Introduction

Weepub aims to help projects publish to npm different versions of their library for different environments (UMD, minified UMD, ES modules, common js, original source).

Use Case

Although not advised, there are some use cases for adding a different version of a library to your project. Here are a couple:

• to decrease install time
• to replace places where a minified file is already being used in the project

Notes

There are some things to consider when opting-in to using different versions of a library:

• increased difficulty in debugging errors when minified
• treeshaking is not possible when minified

Example

• Create folders: For each different version of the library, create a separate directory with a package.json file. It's likely that the directory already exists and contains the file you want to publish as a separate npm module. If that's the case, simply add a valid package.json file to the directory.

redux/
...cjs/package.json
...es/package.json
...umd/package.json
...umd-min/package.json

• Install:

npm install weepub --save-dev

• Configure:

const weepub = require('weepub');

const options =   {
  packages: [
    {
      name: 'cjs',
      source: 'lib/redux.js'
    },
    {
      name: 'es',
      source: 'es/redux.js'
    },
    {
      name: 'umd',
      source: 'dist/redux.js'
    },
    {
      name: 'umd-min',
      source: 'dist/redux.min.js'
    }
  ]
};

• Publish:

weepub( options ).publish();
