rollup-plugin-resolve-index

Resolves Node-style directories with index.js files in Rollup

Rollup by default doesn't handle resolving ./folder to ./folder/index.js/jsx internally. While there is the rollup-plugin-node-resolve plugin which also resolves directories as well as all dependencies from the node_modules directory, these may sometimes be too much for the use case at hand.

Installation

npm install --save-dev rollup-plugin-resolve-index

Usage

1import { rollup } from 'rollup';
2import localResolve from 'rollup-plugin-resolve-index';
3
4// This will resolve `./files` to `./files/index.js` if the file exists
5rollup({
6  entry: './files',
7  plugins: [localResolve()],
8});

if you want to resolve a different file than index.js you can pass a extensions option to the plugin:

1// This will resolve `./files` to `./files/index.js` or `./files/index.jsx` if the file exists
2rollup({
3  entry: './files',
4  plugins: [localResolve({
5    extensions: ['.js', '.jsx'],
6  })],
7});

Things to improve on

• Check for index.js file asynchronously
• Use absolute paths instead of relative ones to be consistent with how Rollup handles modules
