  • How to publish packages to npm (the way the industry does things)

    20th of March, 2019 It’s easy to publish a package to the Node.js package repository. There are two phases to this process:

    1. Create your package.
    2. Publish the package.

    But, do you want to bundle your books the way the market does it? It’s not quite that straightforward. There are still additional measures to take. The procedures will be discussed, and I’ll demonstrate a simple method for publishing and updating your package during the session.

    Creating your first package

    The information in this section is intended for people who have never submitted a package to npm previously.If you’ve already published a piece, feel free to go on to the next part.To publish your first package to npm, you’ll need to go through the following procedures: First and foremost, you must have a npm account.If you don’t already have one, you can create one here.Second, you’ll need to log into your npm account from the command line to begin working.(Before proceeding with this step, you must have Node and npm installed on your PC.

    Install them in this location).You sign in using the npm login command.login with nodejs You’ll be asked to enter your login, password, and email address after clicking the link.The third step is to put together a package.Create a folder someplace on your computer and browse to it in order to accomplish this.The command line interface is as follows: Creating a folder named how-to-publish-to-npm mkdir with the command mkdir how-to-publish-to-npm The cd-folder is being navigated into.

    • how-to-publish-to-npm Following that, you’ll want to run the npm init command to get the project up and running.
    • npm init is a command that starts the npm package manager.
    • This command walks you through a series of questions and generates a package.json file for you at the conclusion of the process.
    • This package.json file includes the absolute minimum of information required to publish your project to GitHub.
    • It is acceptable to skip questions that do not make sense to you.
    • The final step is to use the npm publish command to make your package available for download.

    npm publish is a command that allows you to publish a document.The package already exists on npm (since your package has the same name as another package on npm), and you will not be able to publish it until the package is removed from the repository.You’ll receive an error message.You’ll have to update the name of your bundle.

    If you want to modify the name of your package, you must edit the name field in the package.json file.Here, I updated it to publishing-to-npm to make it more readable.(You may check for naming clashes by searching for them on npm or by using the npm search command.) It’s also a good idea to change the name of the folder in order to maintain consistency.

    1. Here’s how to do it from the command line.
    2. mv is a command to rename folders by moving everything in them.
    3. how-to-publish-to-npm publishing-to-npm Rerun the publish command one more time.
    4. You should be receiving a success message right now.

    What to do if every name you came up with is taken up already

    This is a typical problem, given the large number of users that develop packages using npm.It might be challenging to obtain the package name that you want on occasion.This is similar to how I can never find a domain name.In order to overcome this issue, npm provides the ability to publish to a scope.This implies that you may publish the package under your own username (or npm organization), which eliminates the need to deal with naming issues in the future.You have two options for publishing inside a scope:

    1. Manually change the name of the package to @username/package-name in package.json
    2. Npm init -scope=username should be used instead of npm init.

    If your repository includes a scope, you will need to make a little modification to the publish command: npm publish -access public npm publish -access public That’s all there is to it when it comes to publishing a package to npm. Now, let’s talk about how the publishing sector produces its products.

    The way the industry publishes (and updates) packages.

    Consider the case of a well-known framework such as React.There are a few things you’ll notice if you look around React: First and foremost, React is hosted on Github.Second, the React library is available on npm.Third, React adheres to the Semantic Versioning standard (Semver for short).Fourth, any change made to React is identified by a git tag that is connected with it.This git tag is also used in conjunction with Semver.

    Fifth, each React update is accompanied by a set of release notes.As a result, there are several processes involved in releasing a package.You must, at the very least, do the following:

    1. Tests should be run (if there are any).
    2. Semver recommends that you update the version in package.json.
    3. Create a git tag in accordance with Semver’s instructions
    4. Upload the package to the Github repository.
    5. Push the package to the npm repository
    6. Create release notes for each new version of the software.

    Tests should be performed (if any are available).
    According to Semver, update the version of package.json.
    According to Semver, create a git tag.
    The package should be uploaded to Github.
    The package will be added to the npm install directory;
    For each update, you should provide release notes.


    When we use Np (developed by Sindre Sorhus), it is much easier to publish packages without having to worry about skipping any of the processes I described above.

    Installing np

    You may use the following command to install np on your computer: npm install np npm install np This is effective. However, I like to install np globally on my computer so that I can use the np command from any location. npm install -global np sudo npm install -global

    Before using np

    Before you use np, you should make certain that:

    1. You’ve created a Git repository for your project.
    2. It must be equipped with a remote control.
    3. At the very least, you must have pressed the button on the remote.
    4. You must also ensure that your working directory is free of viruses and other malware.

    Initialize the Git repository git init is a command that creates a remote repository.git remote add origin some-url Commit changes to the remote repository Add a git commit.git commit -m ″Initial Commit″ is a command that commits the first commit.

    1. If your project does not have a Git repository, you will receive the following error: This error will appear if your project does not have remote access (at a later part of the checks).
    2. If your working directory is filthy, you’ll see the following error message: The np command will just hang and accomplish nothing if you haven’t made at least one push to the Git remote.

    Using np

    To make use of np, you must first execute the np command. np np will urge you to submit a Semver number, which you should do. You will be asked to confirm your selection after you have made your selection. np will then take care of the remainder of the publication details for you.

    Error with running tests

    As part of its checks, Np executes the npm test command on the command line.It is possible that if you followed the lesson up to this point, you might receive an error message that looks something like this: As a result of our npm test command returning an error, we are seeing this.You can give it a go yourself: npm test is a command-line tool that tests npm modules.

    1. To resolve this issue, we must make a change to the test script in the package.json file.
    2. For the time being, it appears as follows: In ″scripts,″ the following is an example of a test: ″echo ″Error: no test specified,″ followed by ″echo && exit 1,″ and so on.
    3. Change it to something like this: In ″scripts,″ the following is an example of a ″test″: ″echo ″No test specified.″″ This modification is successful since exit 1 generates an error.
    4. np should be able to finish the publishing process with this modification.
    5. (It’s important to remember to commit the modification before executing np).
    6. At the conclusion of the procedure, np opens a browser window in which you may write your release notes if desired.
    • In summary, np simplifies the process of creating publishing packages!

    This article will walk you through the process of creating and publishing a npm package step by step.

    Create and Publish npm package

    Creating and publishing a npm package will be demonstrated in this tutorial, which will take you step by step.


    In this tutorial, we have shown how to develop and publish a npm package using the Node.js framework. I hope this is of assistance to someone out there! Please spread the word to your friends and colleagues, and please let me know if you have any difficulties while releasing your npm package! Repository: Example of a package:

    A Step-by-Step Guide to Create and Publish npm Package

    • In this article, you will learn how to develop your own Node.js package and submit it to the Node.js repository. You will get an understanding of the following: How to create a npm package using node.js
    • How to test its operation by installing it locally first before distributing it
    • Instructions on how to install and utilize the published package using either the ES6 import syntax or the Node.js require statement.
    • In this section, we will discuss how to handle the package’s semantic versioning.
    • Methods for updating the package to reflect the new version and re-publishing it

    For further detail, you will create a package that returns a list of GitHub repositories belonging to the supplied username, arranged according to the amount of stars each repository has received.


    • To complete this lesson, you will require the following materials: A working installation of Git version control
    • Node.js installed locally, which you may accomplish by following the instructions on this page
    • and a working installation of Git version control.

    Step 1 — Initial Setup

    Start by creating a new folder with the name github-repos-search and then initializing a package in that folder.Make a directory for the json file: mkdir github-repos-search cd github-repos-search use npm init -y to start a new project The following command should be used to set up the current project as a git repository.It should be executed from the github-repos-search folder: Start with git init.

    1. Create a.gitignore file to prevent the node modules folder from being included in your project.
    2. Insert the following material inside the container.
    3. node modules is a gitignore file.
    4. Install the axios package, which will be used to make a request to the GitHub API in the next step.
    5. npm install axios is a command-line program that installs axios.
    6. Your package.json file will now look something like this: Make sure to take a look at our newest offering, the ultimate tailwindcss page maker!
    • The ″name″ of the project is ″github-repos-search″, the ″version″ is ″1.0.0″, the ″description is ″″, the ″main″ is called ″index.js″, the ″dependencies″ are ″axios″: ″0.20.0″, the ″devDependencies″ are ″axios″ and ″devDependencies are ″scripts″: ″test″: ″echo ″Error: no test specified″ && exit 1 The name github-repos-search is defined in the package.json file, which is located at the root of the package directory.
    • As a result, after publishing to the npm repository, the package name will be changed to github-repos-search.
    • Also, the name must be unique on the npm repository, so first determine whether or not such a npm repository already exists by visiting to the npm repository page.
    • If the package name already exists in the npm repository, you will receive an error while attempting to publish the package to the npm repository.

    Step 2 — Writing the code

    • Creating a new file with the name index.js and pasting the following contents into it will result in the following output: const axios = require(‘axios’)
    • const getRepos = async (username =’myogeshchavan97′, page = 1, per page = 30 =>) => => try const repos = await axios.get(‘)
    • return => try const repos = await axios.get(‘)
    • return name:, url: repo.html url, description: repo.description, stars: repo.stargazers count
    • ) return sort((first, second) => second.stars – first.stars)
    • sort((first, second) => second.stars – first.stars)
    • catch (error) return
    • getRepos().then((repositories) => console.log(repositories))
    • getRepos().then((repositories) => console.log(repositories))
    • getRepos().then((repositories) => console.log(repositories))
    • First, let’s get a better understanding of the code. You’ve written a getRepos method that receives an optional object with attributes for the user, the page, and the per page parameter.
    • After that, you utilized object destructuring syntax to extract the properties of the object from the object.
    • Given that passing an object into the method is entirely optional, we have initialized it to default values in the event that the object is not supplied into the function as follows.
    • This is done to avoid receiving an error while destructuring username from the object if the object is not given. = username =’myogeshchavan97′, page = 1, per page = 30
    • Within the method, you are using the GitHub API with the appropriate arguments, which returns the repositories of the specified user, sorted by the date they were last modified.
    • Awaiting axios is same to waiting for const repos. get(‘)
    • get(‘)
    • We are employing the async/await syntax in this case, and the getRepos method is defined as async.
    • The Array map method is then used to choose only the required fields from the answer
    • this is called selective selection. => name:, url: repo.html url, description: repo.description, stars: repo.stargazers count;) return That result is then sorted in decreasing order of stars, with the first piece in the list having the most stars, and so on and so forth.

    • .sort((first, second) => second.stars – first.stars)
    • .sort((first, second) => second.stars
    • The catch block returns an empty array if there is an error
    • otherwise, the catch block returns an empty array.
    • Because the getRepos method is specified as async, you will receive a promise in response
    • thus, you are using the.then handler to obtain the outcome of the getRepos function call and publishing it to the console
    • and

    Once ((repositories) => console.log(repositories)), GetRepos().then((repositories) => console.log(repositories));

    Step 3 — Executing the code

    Now, from the command line, launch the index.js file by entering the following command: index.js The node index.js file is included.You will see a list of the first 30 repositories, which are as follows: Given that you haven’t specified a username in the file, my repositories are displayed by default by default.Let’s make the following update to the code in the example: getRepos(username: ‘gaearon’).then((repositories) => console.log(repositories)); getRepos(username: ‘gaearon’).then((repositories) => console.log(repositories); Once more, run the file by performing the node index.js command, and you should see the following output: Alternatively, you may pass in the page and per page attributes in order to alter the answer so that you only get the top 50 repositories.

    1. getRepos(‘gaearon’ as the username, page: 1, per page: 50 as the per page value).
    2. then((repositories) => console.log(repositories)); then((repositories) => console.log(repositories)); You now have confirmation that the functionality is operational.
    3. Exporting this module will allow you to call the getRepos function from any other file in the future.
    4. As a result, the following code should be removed from the file: getRepos(‘gaearon’, page: 1, per page: 50 ‘).then((repositories) => console.log(repositories)); and replace it with the following code instead: getRepos(‘gaearon’, page: 1, per page: 50 ‘).then((repositories) => console.log(repositories)); module.exports =; module.exports =; You are exporting the getRepos function as a property of the object in this case, so that if you wish to export any other function in the future, you can easily add it to the object as a property of the object.
    5. As a result, the preceding line is the same as the following line: module.exports =; module.exports =;

    Step 4 — Testing the created npm package using require statement

    You have completed the creation of the npm package, but before publishing it to the npm repository, you must test it to ensure that it functions properly when invoked via the need or import statements.There is a quick and simple technique to determine this.From within the github-repos-search folder, run the following command from the command line: github repos search npm link (npm link) When you use the npm link command, a symbolic link is created between your current package and the global npm node modules folder (The same folder where our global npm dependencies get installed).

    1. As a result, you may use the npm package you just built in any project.
    2. In order to verify that the package has been correctly installed, create a new folder on your desktop with whatever name you choose, for example test-repos-library-node, and populate a package.json file with the following contents: make test-repos-library-node in the directory /Desktop testing the repository library node (cd test-repos-library-node) use npm init -y to start a new project If you recall, the name property in our package’s package.json file was github-repos-search; thus, you must need the package with the same name as the property in our package.json file.
    3. After that, from within the test-repos-library-node folder, run the following command to make use of the package you just created: npm link (npm link) github-repos-search Creating a new file with the name index.js and pasting the following code into it will get the desired result: getRepos = require(‘github-repos-search’); const = require(‘github-repos-search’); ().
    4. then((repositories) => console.log(repositories)); then((repositories) => console.log(repositories)); This is an example of how to import a package straight from the node modules folder (This was only possible because you linked it using the npm link).
    5. Now, run the file by entering the following command into the command line: node index.js This is what you will see when you run the program correctly: This demonstrates that when you publish a npm package on the npm repository, anybody may use it by installing it and executing the need statement on the command line.

    Step 5 — Testing the created npm package using the import statement

    By utilizing the need statement, you have confirmed that the package is functional.Let’s check it out with the help of the ES6 import statement.The following command, which should be executed from your desktop folder, will create a new React project: file:/Desktop/npx/cd npx/ test-repos-library-react-create-react-app-test-repos-library-react Now, from within the test-repos-library-react folder, run the following command to make the package you just made available for use: Nodejs link github-repos-search Node.js link Now, open the src/App.js file and replace the following text with the one that follows: The following imports are made: import github-repos-search; import React, from’react’; function App() => useEffect((); import React, from’react’; ((repositories) => console.log(repositories)); return (); getRepos().then((repositories) => console.log(repositories)); return ();

    Open browser console to see the output.

    ); export the default application; Begin by issuing the following command from the terminal to launch the React application: start of the yarn Now, If you look at the output in the browser console, you will find that it is as expected: This demonstrates that when you publish a npm package to the npm repository, anybody may use it by installing it and executing the import statement on the package.json file.

    Step 6 — Publish to the npm repository

    You have now successfully confirmed that the package is operational.It’s time to make it available in the npm repository.Return to the github-repos-search project folder, where you previously generated the npm package, and save your work.

    1. Let’s add some metadata to the package to make it more useful.
    2. The package’s json file is used to display more information about the product.
    3. The completed bundle is shown below.
    4. The json file is as follows: ″The name of the project is ″github-repos-search″, the version is ″1.0.0″, the description is ″″, the main file is called index.js, and the home page is called homepage.js.
    5. The repository’s type is ″git″, the url is ″git+″, the dependencies are ″axios0.20.0″ and ″devDependencies″ are ″axios0.20.0″, and the scripts are called test and echo.
    6. The scripts are called test and echo.
    • [″github″, ″repos″, ″repositories″, ″sort,″ ″stars,″ ″author,″ ″license,″ and ″keywords″]; ″author,″ ″Yogesh Chavan,″ ″license,″ and ″keywords″: [″github″, ″repos″, ″repositories″, ″sort,″ and ″stars″]; and ″keywords″ and ″keywords″ and ″keywords″ and ″keywords and stars.″ ″ For further information, you have included the homepage, repository, keywords, and author (These are optional).
    • Make the necessary adjustments in accordance with your GitHub repository.
    • To use this URL, create a new GitHub repository, and then push the github-repos-search repository to the GitHub server.
    • If you don’t already have an account, go to and register for a new one.
    • Open a terminal window and, from within the github-repos-search folder, type the following command into the terminal: To log in, navigate to npm login and input your npmjs website credentials.
    • After that, execute the following command in order to get it published to the npm repository: npm publish is a command that allows you to publish a document.
    • If you visit to the following address in the browser, you will see your just published package: Now, let’s add a file to the package, which will provide some information about the package.

    Create a new file with the name within the github-repos-search folder and paste the text of this page into it.github-repos-search is a subdirectory of github.Let’s try publishing it once more with the npm publish command this time.You will receive the above-mentioned error.

    This is due to the fact that you are republishing the module with the same version as before.If you look at our package.json file, you’ll notice that the version number in the file is 1.0.0, which is correct.You must increase it each time you publish a new version of the document.So, what should you make the next increase to?You must first grasp the notion of semantic versioning in order to accomplish this.

    Step 7 — Semantic versioning in npm

    Using the dot operator to separate the three numbers, the version value can be calculated.So let’s pretend that the version number is a,b,c.The first value (a in a.b.c) defines the major version of the package — This signifies that this version has significant code changes and may contain API modifications that are potentially dangerous.

    1. The second number (b in a.b.c) denotes the minor version, which contains only minor modifications and will not include any API changes that are considered to be breaking.
    2. The third number (c in a.b.c) provides the patch version, which is generally the most recent one and contains all of the problem fixes.
    3. Because you only inserted a file and did not make any API changes, you may increase the patch version by one number, which is the last digit in our example.
    4. As a result, alter the version number within the package.
    5. Change the version number of the json file from 1.0.0 to 1.0.1 and rerun the npm publish command.
    6. If you go to the npm package page right now, you will notice that the revised npm package is available.


    The npm package you generated in this lesson was submitted to the npm repository, and you earned a certificate for your efforts. Check out the github-repos-search repository on GitHub if you want to see the whole source code from this lesson. You can also view the published npm module by visiting this page.

    Steps to Create and Publish NPM packages

    • It is our goal in this tutorial to teach you how to create and publish your own npm package (also called an NPM module). There are several advantages to using NPM packages, some of which are described below: Code that may be reused
    • Managing code (via the use of versioning)
    • Collaborating on code
    • As seen below, the life cycle of a npm package follows the following form: Modular Life-Cycle 1. Establish a New Project: Before beginning any work, it is necessary to establish a project. Install Node.js on your computer.
    • Create an account with npm using account.npm-signup
    • Using the npm login command, logging into the npm account
    • Npm-login
    • In order to initialize a module, the following steps must be taken: Navigate to the terminal/command-line and type npm init, followed by the appropriate commands. npm-init Set the version prompt to 0.0.0 in the version prompt. It is responsible for initializing the module. Maintaining the 1.0.0 version number indicates that the current module version is the first major release available to possible downloaders of the module. It goes without saying that you don’t want the first big release to be a complete whitewash and full of problems.
    • During the main prompt, select the module’s entry point from the drop-down menu. Those who are interested in downloading the module will use it as an entrance point to the module. Make a note of the path to the entry point, which is’src/index.js,’ which is considered common practice these days to place your code in a directory called’src.’
    • Simply enter the command ″test″ into the command prompt. Because of a typographical error in the photograph above, it has been cropped out of the image. You have the option of changing your test command from the package that will finally be formed. as well as a json file
    • You can provide the url of the git repository where the package will be hosted in the git repository prompt
    • however, this is not required.
    • Fill in the keywords, author, and license information, or simply press ‘Enter’ to navigate your way through them. These might be updated at a later time within the package. json
    • Potential downloaders will be able to read the file that is included with the project. This will be displayed on the module’s homepage when it is activated. It is important to note that the file should be in markdown. A file should be included with a npm module in order to serve potential users with information such as module descriptions, how to use the package, how to contribute to the package, and so on.
    • It is preferable, in the end, if our project directory resembles the following structure: project-directory-structure 3. Constructing a module: This step is referred to as the coding phase. In case you have any previous experience with NPM modules, you are probably aware that NPM modules expose methods that are then called by the project. A common control-flow diagram is as follows: Function-call-workflow-that-present-in-npm-module Let’s start by creating a basic function in the npm module that adds two integers together. The following is an example of this function: The following is the file name: index.jsconst gfgFns = gfgFns is the value of module.exports. It is important to note that the index.js file has a certain structure (which is the entry point of npm module that we are building). GfgFns is the object that is exported for usage by other programs.
    • Add: addTwoNums is a function that adds two numbers () The name of the function (addTwoNums) is denoted by the symbol ‘add’. This function to add two integers is referred to as the ‘add’ function because of its name.
    • GfgFns is the value of module.exports. After that, the gfgFns object is exported with the given name. When this function needs to be utilized in a different file than the current one
    • 4. Publishing a module: Once the coding module has been completed, the npm package should be published. There is one thing to bear in mind while publishing the package: if your package name already exists in the npm registry, you will not be allowed to publish your package until the name is changed. Check whether your package name is usable by going to the command line and typingnpm search packagename. If your package name is useful, it should look somewhat like the image below when you run the command. npm-search-gfgnpmpkgupload-cmd-1 You can alter the module name in the package.json file of the npm module project if the name you want to use already exists in another module. After you’ve checked for name availability, you should proceed to the command-line/terminal and do the following steps: npm publishnpm-publish-cmdnpm-publish-cmdnpm-publish-cmdnpm-publish-cmd Now, let’s put this module to the test and see how well it performs. Create a new project directory for your work
    • In the terminal, execute npm init to start the Node project from the beginning.
    • After that, run npm install gfgnpmpkgupload to get the npm module that we recently created.
    • Appjs-npmpkgupload-directory-add function
    • Now that everything is in place, let’s try running the node.js file to check whether our module was successfully uploaded, published, imported into our new project, and utilized.
    • Node-appjs-add(4+5=9)-run-success-11
    • 5. Managing and updating versions: When software is being built, it is inevitable that it will have several versions. Various versions are created as a consequence of bug corrections, small upgrades, significant improvements, and significant releases. NPM gives us with the following features to help us with version control. Coding for versioning and publishing: On the basis of semantic-versioning, NPM allows us to update our module’s version number. It is possible to do three different sorts of version bumps, namely patch, minor, and major. For example, if the current module version is 0.4.5, the following would be true: Take note of how minor version upgrades reset patch versions to 0, and how major version upgrades reset minor and patch versions to 0. > npm version patchupdate version to 0.4.6 > npm version minorupdate version to 0.5.0 > npm version majorupdate version to 1.0.0 > npm version majorupdate version to 1.0.0 When we run the aforementioned script, the version number in the package.json file is immediately changed as well, which is convenient. Note that if a module is re-published without the version number being updated, the NPM command-line will generate an error message. Examine, for example, the image on the right. Because the version number has not changed, npm publish has failed. ‘npm publish’ failed in this case because it was attempted without boosting the version number, resulting in a command-line error. It should go without saying that you cannot downgrade the version. In the case of 0.1.2, the version number cannot be changed to 0.1.1. What happens if a user has an outdated version of the module on their computer? It is sufficient for users to simply repeat the npm install packagename command once a npm module has been re-published (updated) in order to obtain the most recent version of the module. A package that is reliant on other packages: When producing packages, it is customary to search for, utilize, and notice dependencies in other packages. The following is an example of how this is accomplished: Install the dependencies that your npm module will require in the npm module project
    • this will be done in the npm module project.
    • Install those dependencies into your project by running npm install packagename1 in your project directory. Check that the ‘dependencies’ field in the package.json file has been updated to include the references to these dependencies. Please keep in mind that the dependencies and their versions that are listed here will be carried forward with the npm package.
    • Simply publish the module after ensuring that all of the preceding steps have been correctly completed using > npm version minor npm publish, as shown below.
    • Ideally, the above method will complete properly, and the results should be accessible to view on the npm registry website, as shown below:
    • Three-dependencies
    • -prompt-jest-mathsjs

    Consider the following scenario: we’ll try to develop a module that reads a text file, parses the numbers in the file, adds them all together and displays the result in a terminal.This is what our npm module should look like in order to accomplish this.Now that we have our module established, let’s import it into our new project with the help of npm install gfgnpmpkgupload npm install gfgnpmpkgupload Run runnpm init -y before performing the above command to ensure that the project has been properly set up.

    1. Create your project in the following manner: The npmpkguploadtest project’s organizational structure There should be a numFile.txt file in each of the datafiles, which contains the numbers that need to be added and shown in the console./ numFile.txt – sum = 55 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 We will have a gfgapp.js file that will perform the actual addition in order to consume this numFile.txt.
    2. npmpkguploadtest-gfgappjs Go to the command-line and type node gfgapp.jsnode gfgappjs command-line view to see if this is true.
    3. run a successful race The boilerplate for the NPM module is as follows: On, you may get boilerplates for NPM modules that can be used for project bootstrapping.
    4. There are several technology combinations available, and you may choose the generator that best suits your needs.
    5. To begin, navigate to Yeoman Generator.
    6. Search and search for anything like ‘npm module boilerplate’ or something along those lines.
    • Unpublishing an NPM package consists of the following steps: An NPM package should be removed from the internet within 72 hours of its initial publication.
    • The second option is to get in touch with the npm registry.
    • If you want to remove your publication from the web within 72 hours, use the following command: npm unpublish packageName (npm unpublish packageName) If you want to learn more about unpublishing packages from the registry, check out NPM’s unpublishing packages from the registry page.
    • Example: To add two numbers, you can use the published package.
    • Filename: app.jsconst GFGFns = require(‘gfgnpmpkgupload’);console.log(GFGFns.add(4, 5));console.log(GFGFns.add(4, 5));console.log(GFGFns.add(4, 5)); Output:node-appjs-add459-run-success-1

    How to publish NPM packages

    • Let’s say you’ve created a JS project and want to share it with the rest of the world. Whether it’s a simple project that draws a circle (which may or may not be the package you want to publish) or a complex project that you want to be used by thousands of developers, such as Jquery, you can publish them on NPM. There will be three sections to this: Publishing to NPM in the usual manner
    • Making use of GitHub Actions to automate the publication process
    • Additionally, you may use GitHub Actions to test your projects.

    Publishing Your Package

    So you’ve decided on a project.You want it in a package-ready format so that you can publish it as soon as you’re ready.All NPM Packages have the same structure, which is as follows: As a result, the index.js file contains the majority of our code.

    1. You should be familiar with the concept of a, and I recommend that you include one in your project to make it more appealing on NPM.
    2. The LICENSE file is very essential, and you should make sure you pick the right one.
    3. is a website where you may choose a license.
    4. Following the completion of these two file sets (and making certain that you do not proceed without them), we may go to the package.json and package-lock.json files.
    5. These are essential since they inform NPM of the existence of the package.
    6. Check to see that you have NPM and Node.js installed; if you don’t, you can learn how to install NPM by visiting this page.
    • In this case, we have NPM, Node.js, and the LICENSE,, and index.js files, among other things.
    • The package.json file may be created by simply opening up your terminal or command line and entering the following command: This will guide you through the instructions necessary for setting up your project; feel free to skip questions if you don’t understand them; nonetheless, it shouldn’t be too difficult to complete.
    • In addition, if you do not wish to include a question, such as a testing script if you do not have one, you can leave the question blank.
    • The package-lock.json file should be generated as well (if npm I wasn’t run previously).
    • If you’ve ever constructed a Python package, you’ll recognize that the package.json file is nearly identical to the file.
    • Despite the fact that the npm init command leads you through some of the most important elements of the package.json file, there are a few more items you may include, which you can find in the entire list of things to include here.
    • To publish npm packages, you must first register and create an account at npm.

    Then you must run the command on your terminal or command prompt.Log in using the credentials associated with your NPM account, which you created when you enrolled.Okay, now that we’ve generated all of our files and signed in, what should we do?We have finished publishing the product!

    You should go through your package one last time to make sure everything is as you want it to be, and to ensure that there are as few issues as possible (you might want to modify the version to v.x.x alpha or beta instead in case there is a bug you don’t spot), and then run the last command: Hooray for you!We completed the task!Did we, or didn’t we?To be honest, it’s kind of true.If you did not receive an error, you are in excellent shape; nonetheless, you may face an error that prevents it from being published.It’s possible that someone else is already using the name that you provided in your package.

    If the error it generates looks something like this:

    1 You do not have permission to publish. Are you logged in as the correct user?

    Then you have a problem on your hands.If this is the case, there are two possibilities.The first method is self-explanatory: come up with a new name.

    1. However, if you truly enjoy your given name and want to preserve it, you may scout it out for yourself.
    2. This is something that many people do, and although it will be visible to others on NPM, it does not appear to be that problematic.
    3. Simply modify the name of your package from name to @npmusername/package-name, and you’re done.
    4. Replace @npmusername with your NPM username and package-name with the name of your package as it appeared in the NPM repository.
    5. Example: If your NPM username is QLabs, and the package name is minor, you may alter the name of the package to @QLabs/minor.
    6. If you continue to receive an error message, you will be prompted to upgrade your NPM account, which will include a fee.
    • If this is the case, you do not have an issue in your package.
    • json.
    • Instead of doing npm publish, try executing:
    1 npm publish -access public

    Otherwise, you may have made a clerical error when packaging the item(s).You either didn’t include a json file or you didn’t include one.If not, you should put it on hold until you get your question answered.

    1. Having corrected all of our problems and released the package, we can now test to ensure that we followed the procedures correctly.
    2. The npm install command is used to install Node.js.
    1 npm install

    If you scoped the problem when attempting to solve it, be sure to include the scope when installing the solution. So we went ahead and did it! We were successful in our attempt to generate an NPM Package! But don’t go just yet. There’s more to it than that.

    Using GitHub Actions to Automatically Publish Releases on NPM

    Image courtesy of Luke Chesser via Unsplash.Because practically everyone uses GitHub, I strongly advise you to make use of it and to upload your source code to it as well.Now, the vast majority of packages are hosted on GitHub, which provides some interesting advantages through the usage of GitHub Actions.

    1. Don’t be concerned if you’ve never worked with one before.
    2. It’ll be as simple as pie from here on out.
    3. Firstly, navigate to your package’s GitHub repository and then to settings>secrets, where you may create a new secret.
    4. To generate an access token for the value of our GitHub secret, go to the NPM repository, log in, then go to ″ and create a new access token for the value of our GitHub secret.″ Double-check to make sure the ″Read and Publish″ access level is selected, then click on the ″Create Token″ option.
    5. Copy the token and paste it as the value into the GitHub Secret field on the right.
    6. Navigate to the Actions tab on GitHub at this point.
    • The first part of the GitHub Actions Tab should be labeled ″Workflows created for your JavaScript repository,″ and it should be located at the bottom of the page.
    • On the ″Publish Node.js Package″ process, select ″Set up this workflow″ from the drop-down menu.
    • The editor should appear with code that has already been written.
    • It should be replaced with:
    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 name: Publish on: release: types: jobs: build: runs-on: ubuntu-latest steps: – uses: actions/[email protected] – uses: actions/[email protected] with: node-version: 12 registry-url:- run: yarn install – run: npm publish -access public env: NODE_AUTH_TOKEN: $

    Let’s go over the steps of the procedure. When you go to the actions tab on your repository once the action has been created, you will see the name that was assigned to it.

    1 2 3 on: release: types:

    This means that it will run every time you publish a new release on GitHub, saving you the time and effort of having to go to the command prompt and type npm publish each time you want to publish a new version on the platform.

    1 2 3 jobs: build: runs-on: ubuntu-latest

    This configures the task build and ensures that it is running on the most up to date version of Ubuntu.

    1 2 3 4 5 6 7 8 9 10 steps: – uses: actions/[email protected] – uses: actions/[email protected] with: node-version: 12 registry-url: – run: yarn install – run: npm publish -access public env: NODE_AUTH_TOKEN: $
    • This is where we will set the steps of the task that will be executed. It does the following: Obtains the repository files
    • Installs Node.js, Version 12, using the NPM registry URL as a point of entry
    • Installation of package dependencies using the yarn install command.
    • The npm publish command is executed, and the –access public flag prevents the problem from occurring again. When it is run, the environment variable NODE AUTH TOKEN is assigned to the secret we established before.

    Every time a new release is published on GitHub, a new release will be instantly published on NPM as well.

    Using GitHub Actions for CI on Your NPM Project

    Image courtesy of Markus Winkler via Unsplash.What more things can we accomplish with GitHub now that we’ve automated publishing with GitHub Actions?GitHub, on the other hand, provides a simple approach to perform continuous integration using GitHub Actions.

    1. Create a new file in the.github/workflows directory of your repository’s git repository.
    2. Copy and paste the template supplied by GitHub on their documentation page:
    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 name: Node.js Package on: release: types: jobs: build: runs-on: ubuntu-latest steps: – uses: actions/[email protected] – uses: actions/[email protected] with: node-version: ’12.x’ registry-url: ‘ – run: npm install – run: npm publish env: NODE_AUTH_TOKEN: $

    Let’s walk through this process step by step. You may customize the name that will appear on the actions tab to anything you want it to be. This is executed every time you make a change to the repository.

    1 2 3 jobs: build: runs-on: ubuntu-latest

    This determines which operating system will be used to test it. Based on whatever operating system you wish to test on, you may modify the value to windows-latest or macos-latest.

    1 2 3 strategy: matrix: node-version:

    This defines the node versions that will be tested on; you may change the versions that will be tested on at any time.

    1 2 3 4 5 6 7 8 9 10 11 steps: – uses: actions/[email protected] – name: Use Node.js $ uses: actions/[email protected] with: node-version: $ – run: npm install – run: npm run build -if-present – run: npm test env: CI: true

    The final section is the one we should pay attention to:

    1 2 3 4 5 – run: npm install – run: npm run build -if-present – run: npm test env: CI: true
    • This:Installs the package dependencies by using the npm install command line tool
    • This command executes the build steps specified in your package.
    • Json use npm run build
    • The npm test command executes your test script, which is declared in your package as a dependency.
    • Json


    • We completed the task! We were able to successfully publish an NPM Package. That, however, is not the case! In conclusion, I would like to say that Publishing to NPM in the usual manner
    • Making use of GitHub Actions to automate the publication process
    • Additionally, you may use GitHub Actions to test your projects.
    • Despite the fact that NPM appears to be a competent package management, there is another JS package manager available: Yarn (there is also pnpm, but I don’t use it much).
    • So, which one should you use?
    • NPM is required since Yarn does not have the ability to publish packages, however Yarn is extremely efficient.

    My preference is to use both since Yarn installs faster while NPM takes longer (albeit not much longer), and because NPM can publish packages and perform other things that Yarn cannot.For further information, you should read this essay by Harsha Vardhan, which appears in the JavaScript in Plain English collection.

    Further Reading, Examples, & Package Managers

    • It is explained in this post by Harsha Vardhan, who writes for the JavaScript in Plain English magazine, what the distinctions are between Yarn and NPM.
    • Pnpm
    • \sYarn
    • According to Matt Goldwater’s essay in the JavaScript in Plain English publication, the history of all of the package managers as well as the problems that they tackled are discussed.
    • A fairly nice tutorial on publishing NPM packages and also using NPM to test packages can be found on, written by Zell Liew, and can be found here.

    Creating and publishing scoped public packages

    You may publish public user-scoped or organization-scoped packages to the npm registry if you want to make your code available to the public under a user or organization namespace. More information on scopes may be found under the heading ″About scopes.″

    Creating a scoped public package

    1. If you are using npmrc to manage accounts on several registries, you must switch to the appropriate profile on the command line.
    2. Create the following directory for your package using the command line:
    3. Navigate to the following directory at the root of your package:
    4. If you are using git to manage your package code, you may execute the following commands in the package root directory, substituting git-remote-url with the git remote URL for your package:
    5. Initiate a git remote by adding the origin git:/git-remote-url to the command line.
    6. Run the npm init command in the package root directory, passing the scope parameter to the scope flag as follows:
    7. If you want a package that is exclusive to your organization, replace my-org with the name of your organization:
    8. If you want to create a package that is only accessible by your username, use the following command: npm init [email protected]
    1. Responses to the prompts will result in the creation of a package.json file. See ″Package name recommendations″ for assistance in naming your package.
    2. Create a README file that describes what your package code is and how to utilize it.
    3. Write the code for your package in your favourite text editor
    4. then save it.

    Reviewing package contents for sensitive or unnecessary information

    • Users can be harmed by publishing sensitive information to the register.
    • It can also jeopardize your development infrastructure, which can be expensive to repair, and put you at danger of legal action.
    • We highly advise that you remove any sensitive information from your package before submitting it to the registry, such as private keys, passwords, personally identifying information (PII), and credit card data.

    When dealing with less sensitive information, such as testing data, a.npmignore or.gitignore file can be used to prevent information from being published to the registry.More information may be found in this article.

    Testing your package

    We recommend that you test your package before submitting it to the npm registry in order to minimise the possibility of publishing problems. To test your package, run npm install with the complete path to the directory containing your package:

    Publishing scoped public packages

    By default, scoped packages are published with private visibility and are not publicly accessible. For public exposure, you can use the npm publishing command with the -accesspublic option for scoped packages.

    1. To begin, browse to the root directory of your package from the command line.
    2. To publish your scoped public package to the npm registry, run:npm publish -access public
    3. to publish your scoped private package to the npm registry, run:npm publish -access private
    4. Alternatively, you may visit by changing package-name* with the name of your package and clicking on ″View Public Package Page.″ On the npm website, public packages will be identified by the word public after the package name.

    Consult the CLI documentation for further information on how to use the publish command.

    Before we begin…

    • Before we begin, please ensure that the following items are prepared. Account on GitHub
    • NodeJS and npm are installed
    • a npm account has been created.

    Choosing a package name

    • You must first determine whether the desired name is accessible for the npm package. If you are publishing an unscoped (public) package, the name of the package should be distinct from the rest of the packages. Alternatively, if you are publishing a scoped (private) package, the name does not need to be unique, and the name takes the format @npm username/package-name rather than @npm username/package. Read more about scoped packages, package name guidelines, and package naming conventions.

    Initializing the npm package

    • Create a new directory and initialize using npm init
    $ npm init Enter fullscreen mode Exit fullscreen mode Initializing package will ask you a few questions for setup. The default package.json file will be created in your project directory { ″name″: ″number-to-comma-format″, ″version″: ″1.0.0″, ″description″: ″Convert a number to comma separated format″, ″main″:
