In this modern era of software development, working with open source libraries and packages has become a norm. However, businesses often require more privacy and security while using third-party libraries and packages. GitHub, one of the most popular web-based hosting services for version control, provides private repositories that can be used to maintain the necessary level of privacy.
NPM (Node Package Manager) is also a widely used tool to install and manage dependencies for Node.js projects. It allows the developers to share and reuse code easily. In this article, we will explore how to use a private GitHub repository as an NPM dependency with code examples.
Step 1: Create a Private GitHub Repository
The first step is to create a private repository on GitHub that will be used as an NPM dependency. To create a private repository, you need to go to GitHub and create a new repository with the “Private” option enabled.
Once the repository is created, you need to add the necessary code files to the repository, and commit and push them to the master branch of the repository. Make sure that you include a package.json file in the repository as well. This file should contain all the necessary information about the package, such as name, version, dependencies, etc.
Let's create a new package from scratch for this example. Create a new directory named “npm-private-github” on your local system. Inside the directory, create a new file named package.json and add the necessary details.
{
"name": "npm-private-github",
"version": "1.0.0",
"description": "Demo private npm package repo on Github",
"main": "index.js",
"dependencies": {
"lodash": "^4.17.15"
}
}
As you can see, we have added the name, version, description, main file, and dependencies in the package.json file. We have included the lodash library as one of the dependencies.
Step 2: Generate a Personal Access Token
To install dependencies from a private GitHub repository, you need to authenticate yourself using a Personal Access Token (PAT). To generate a PAT, go to GitHub's settings and navigate to the Developer Settings > Personal Access Tokens section. Click on the “Generate new token” button to create a new token.
Select the “repo” scope for the token and click on the “Generate token” button. You will see the token generated on the screen. Make sure to copy the token value somewhere safe so that you can use it later.
Step 3: Install the Dependencies from Private GitHub Repository
Now that we have created the private GitHub repository and generated the PAT, we can install the dependencies from the private repository using the NPM command.
To install the package from the private GitHub repository, we need to add the repository URL and the PAT as the prefix to the package name in the dependencies array of the package.json file.
{
"name": "npm-private-github",
"version": "1.0.0",
"description": "Demo private npm package repo on Github",
"main": "index.js",
"dependencies": {
"lodash": "^4.17.15",
"my-private-github-repo": "https://myusername:${PAT}@github.com/myusername/my-private-github-repo.git"
}
}
As you can see in the above package.json file, we have added the URL of the private GitHub repository and the PAT generated in Step 2. We have also added an imaginary name “my-private-github-repo” to represent the actual package name of the private GitHub repository.
After adding the dependencies in the package.json file, run the following command to install the dependencies:
npm install
This command will install the dependencies from the public registry, as well as the private GitHub repository.
Step 4: Verify the Installation
After completing the installation, verify that the private package has been installed successfully. To do that, we can list all installed packages using the following command:
npm ls
This command will show the list of all installed packages in the project. You should be able to see the private GitHub package in the list.
Step 5: Using the Private GitHub Package
Now that we have installed the private GitHub package, we can use it in our application. In this example, we will create a simple “index.js” file and use the lodash library and the private GitHub package to demonstrate how to use them.
// index.js
const _ = require('lodash');
const myPrivateRepo = require('my-private-github-repo');
console.log(_.reverse(['Hello', 'World'])); // Output: [ 'World', 'Hello' ]
console.log(myPrivateRepo.greet()); // Output: Hello, this is my private repository on GitHub!
As you can see in the above code, we have imported the lodash library using the “require” method. We have also imported the private GitHub package using the package name we defined in the package.json file.
Finally, we have used both libraries in the console.log statements to reverse an array of strings using lodash and to print a greeting message from the private GitHub package.
Conclusion
Using private GitHub repositories as NPM dependencies is a great way to maintain privacy and security in your projects. In this article, we have covered the steps required to use a private GitHub repository as an NPM dependency with code examples. We hope that this article has provided you with a good understanding of how to use private GitHub packages, and you can now incorporate them into your projects to maintain the necessary level of privacy.

Private GitHub Repositories
Private GitHub repositories are repositories that can only be accessed and viewed by authorized users. They are used by businesses that require more privacy and security when using third-party libraries and packages. Private repositories are not visible to the public and can only be accessed by those who have been granted permission by the owner of the repository.
GitHub provides free unlimited private repositories for individuals, as well as teams. Private repositories are also available for organizations, but they come with a cost, depending on the number of users and the storage needed.
Personal Access Tokens (PATs)
Personal Access Tokens (PATs) are used to access your GitHub account from the command line. They are similar to a password and should be kept confidential. PATs can be used to perform various actions on GitHub, such as accessing private repositories, creating and deleting repositories, managing issues and pull requests, and many more.
PATs are generated from the GitHub website, and they can be scoped to provide access to certain privileges, such as only access to specific repositories. PATs can also have expiration dates set, meaning they will only be valid for a certain period of time.
Node Package Manager (NPM)
Node Package Manager (NPM) is a package manager for Node.js. It allows developers to easily install, update, and manage dependencies for Node.js projects. NPM provides a public registry where developers can publish open-source packages and share them with others.
NPM is widely used in the Node.js development community, and it is the default package manager that comes with Node.js. NPM can be used to install packages locally, as well as globally, and provides many useful commands to help manage dependencies, such as "npm install", "npm update", "npm uninstall", and many more.
Using a Private GitHub Repository as an NPM Dependency
Using a Private GitHub Repository as an NPM Dependency is a great way to maintain privacy and security in your projects. It allows developers to use code from private repositories in their projects without making them public. This method involves adding the URL of the private repository and a Personal Access Token (PAT) as a prefix to the package name in the dependencies array of your project's package.json file.
Once the dependencies are added, running "npm install" will install all the dependencies, including those from the private GitHub repository. Developers can then use the private packages just like they would with any other package that is publicly available in the NPM registry.
Conclusion
In conclusion, using private GitHub repositories as NPM dependencies is a great way to maintain privacy and security in your projects. It allows businesses to use third-party libraries and packages without compromising the security of their code. Personal Access Tokens (PATs) provide the necessary authentication to access the private repositories, and Node Package Manager (NPM) simplifies the process of managing dependencies and installing packages in Node.js projects.
