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 @ayan4m1/rollup-plugin-multi-input
yarn add @ayan4m1/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
