How to load library in JS repl in a yarn project?

Question

I have a project with a package.json file, generated by YARN.

How can I load a js REPL and load a library that's specified in the package.json file?

Answer 1

With npm or with yarn you can download and install locally all the dependencies specified in a package.json file.

First thing is to run the install command:

my-project $ npm install

or

my-project $ npm install

This command is going to install locally all the dependencies in your package.json file.

Now you should have a new folder node_modules that contains all the code.

On a js file:

// index.js
const myLib = require('myLib')

Now you can work with the library.
