rollup-plugin-multi-input

:warning: Do you really need rollup-plugin-multi-input?

Take a look at the rollup preserveModules and preserveModulesRoot options.

A rollup plugin to bundle modular libraries with sub directories.

• Use multiple entry points.
• Use glob in entries.
• Preserve src tree structure in the dist folder.

Install

Install via npm or yarn.

npm i -D rollup-plugin-multi-input
yarn add rollup-plugin-multi-input

Setup

In the rollup configuration

import multiInput from 'rollup-plugin-multi-input';

export default {
    // use glob in the input
    input: ['src/**/*.js'],
    output: {
      format: 'esm',
      dir: 'dist'
    },
    plugins: [ multiInput() ],
};

If using a rollup version lower than 1.0.0 enable experimentalCodeSplitting.

It's possible to mix input type.

• use glob in array

  input: ['src/**/*.js']
  

• use object input configuration

  // DO 👍
  input: [{
    output1: 'src/output1.js'
  }]
  // DON'T ❌ (glob not supported yet)
  input: [{
    output1: 'src/**/*.js'
  }]
  

• use glob string and object configuration

  input: ['src/more/**/*.js', 'src/more2/**/*.js', {
    output1: 'src/output1.js'
  }]
  

Options

relative 'src/'

Specify the relative path to use in the dist folder.

Example:

import multiInput from 'rollup-plugin-multi-input';

export default {
    input: ['src/bar.js', 'src/foo/bar.js'],
    output: {
      format: 'esm',
      dir: 'dist'
    },
    plugins: [ multiInput({ relative: 'src/' }) ],
};
// create the files dist/bar.js and dist/foo/bar.js

transformOutputPath

A callback for transforming output file path.

Example:

import multiInput from 'rollup-plugin-multi-input';
import path from 'path';

export default {
    input: ['src/bar.js', 'src/foo/bar.js'],
    output: {
      format: 'esm',
      dir: 'dist'
    },
    plugins: [ multiInput({ 
        relative: 'src/', 
        transformOutputPath: (output, input) => `awesome/path/${path.basename(output)}`, 
    }) ],
};
// create the files awesome/path/bar.js and awesome/path/foo/bar.js

glob {}

fast-glob object configuration.
