@itrocks/prepare-module v0.0.24

prepare-module

Prepare your front-end module with dependencies for npm publishing.

Pre-requisites

• Your project is a library you intend to publish on npm,
• your project contains front-end ESM scripts in a src subfolder,
• your transpiler generates transpiled .js and .d.ts files into src,
• you want to import ... from '@itrocks/something' without TypeScript errors.

Installation

Install @itrocks/prepare-module as a development dependency:

npm i @itrocks/prepare-module --save-dev

Usage

In your project, install the required dependency and import the necessary front-end script with a relative path:

import { SortedArrayBy } from '../node_modules/@itrocks/sorted-array/sorted-array.js'

Then, add the following to your packages.json file:

{
	"scripts": {
		"prepare": "prepare-module"
	}
}

How It Works

When your publish your package using npm publish, prepare-module will handle the following tasks:

• Copies your js script and .d.ts files from src to your project root directory,
• Updates the import paths in your script to relative imports within node_modules, as shown below.

If your project is published under the same namespace as the dependency:

import { SortedArrayBy } from '../sorted-array/sorted-array.js'

If published under a different namespace:

import { SortedArrayBy } from '../../@itrocks/sorted-array/sorted-array.js'

If published without a namespace:

import { SortedArrayBy } from '../@itrocks/sorted-array/sorted-array.js'

Deployment

When coding with TypeScript, avoid deploying files in src/*.js: the scripts in your project root directory are the final ones to be used.
