Rollup plugin to allow specification of 'input' array using globs, e.g. input:'./**/*.js'

Maintaining arrays of input files in the Rollup config requires additional thinking when adding a file to a site.

Wouldn't it be great if we could just set Rollup to look at a folder and run for every file that happens to be in there?

This plugin allows exactly that.

This plugin is not a way of specifying that multiple files should be merged into one file, for that the multientry plugin already exists.

Using npm:

npm install --save-dev rollup-plugin-folder-input

*note: if you don't have Rollup installed yet, go do that first.

In the rollup.config.js file add

import { folderInput } from 'rollup-plugin-folder-input'

and make sure the plugin is added at the very start of your plugin list.

  plugins: [
      folderInput(), 
      /* other plugins here */
  ],

then you can use standard Globs in your input specification, e.g.

  input: './src/*.js',

Create rollup.config.js with the following:

import { folderInput } from 'rollup-plugin-folder-input'

export default {
  input: './src/*.js',
  plugins: [folderInput()],
  output: {
    dir: './dist',
    format: 'es',
    plugins: []
  }
}

Run from the command line with

npx rollup -c rollup.config.js

For details on the glob format see the fast-glob documentation
