What is Yarn?

Yarn is a fast, reliable, secure package manager for JavaScript developed by Facebook. It is crucial in modern software development for efficiently managing dependencies, ensuring consistent installations across different environments, and avoiding version conflicts. Yarn's use of a lock file (yarn.lock) and a global cache for downloaded packages streamline the development process, making it an essential tool for developers on platforms like AlmaLinux, where it simplifies the management of JavaScript dependencies in projects

Prerequisites

  • Operating System and Version: AlmaLinux OS 8.
  • Ensure you have root or sudo access to install the Yarn.

Step #4. Create a JavaScript file (index.js) in the project directory

Open the JavaScript file index.js and use the following command:

nano index.js

Then, add the following details:

// index.js
const _ = require('lodash');

console.log(_.capitalize('This is the sample yarn project!'));

Step #5. Run the JavaScript file

To run the JavaScript file, use the following command:

node index.js

Here is the output:

[root@yarn-alma sample-yarn-project]# node index.js
This is the sample yarn project!

Step #6. Add scripts to the package.json (optional)

To run commonly used commands, add scripts to the package.json file. For example, add a script to run the index.js file:

"scripts": {
  "start": "node index.js"
}

Here is the output:
