How to Use Lerna to Create a Monorepo for Multiple Node Packages

Create two packages, hello-world, and aloha-world (with the default options):

0 reactions
lerna create hello-world
lerna create aloha-world
lerna create
 is Lerna’s way to help us create packages managed by a Lerna initialized repo.
0 reactions

Inside both of the packages, modify the corresponding js files to have them greet as we want them to:

0 reactions

aloha-world.js

0 reactions
'use strict';

module.exports = alohaWorld;

function alohaWorld() {
 console.log('Aloha World');
}

hello-world.js

0 reactions
'use strict';

module.exports = helloWorld;

function helloWorld() {
 console.log('Hello World');
}

Now we have to make a modification in our package.json to contain the GitHub username of our account / organization:

0 reactions
{
 "name": "@aspectom/aloha-world",
 "version": "0.0.0",
 "description": "> TODO: description",
 "author": "Tom Z <[email protected]>",
 "homepage": "",
 "license": "ISC",
 "main": "lib/aloha-world.js",
 "directories": {
   "lib": "lib",
   "test": "__tests__"
 },
 "files": [
   "lib"
 ],
 "repository": {
   "type": "git",
   "url": "[email protected]:aspectom/learna.git"
 },
 "scripts": {
   "test": "echo \"Error: run tests from root\" && exit 1"
 }
}
