Heroku NPM Install Global

Introduction

Heroku is a cloud platform that allows developers to build, run, and scale applications easily. The NPM (Node Package Manager) is a package manager for the Node.js runtime environment. In this guide, we will learn how to use Heroku to install NPM packages globally.

Prerequisites

Before we begin, make sure you have the following:

• Heroku CLI: You need to have the Heroku Command Line Interface (CLI) installed on your machine. You can download it from the official Heroku website.
• Node.js: Ensure that you have Node.js installed, as NPM comes pre-installed with it. You can download Node.js from the official Node.js website.

Steps

Follow these steps to install NPM packages globally on Heroku:

1. Open your terminal or command prompt and log in to your Heroku account using the following command:

   heroku login
   

   This command will prompt you to enter your Heroku credentials.

2. Create a new Heroku application by running the following command:

   heroku create <app-name>
   

   Replace <app-name> with the desired name for your application.

3. Set the Node.js buildpack for your Heroku application by running the following command:

   heroku buildpacks:set heroku/nodejs
   

4. Create a file named package.json in your project's root directory, if it doesn't exist already. Add the NPM package(s) you want to install globally to the dependencies section of this file.

   {
     "name": "<app-name>",
     "version": "1.0.0",
     "dependencies": {
       "<package-name>": "<package-version>"
     }
   }
   

   Replace <app-name> with your application name, <package-name> with the NPM package name, and <package-version> with the desired package version.

5. Commit your changes to Git by running the following commands:

   git init
   git add .
   git commit -m "Initial commit"
   

6. Deploy your application to Heroku using the following command:

   git push heroku main
   

7. Once the deployment is complete, run the following command to open a shell session on the Heroku dyno:

   heroku run bash
   

8. Within the Heroku shell, run the following command to install the NPM package(s) globally:

   npm install -g <package-name>
   

   Replace <package-name> with the NPM package name you added to the package.json file.

9. Exit the Heroku shell by running the exit command.

Conclusion

You have successfully installed NPM packages globally on Heroku using the Heroku CLI. Remember to include the desired packages in your package.json file and follow the necessary steps during the deployment process. Now you can utilize globally installed NPM packages in your Heroku application.
