rollup-plugin-alias

Define aliases when bundling packages with Rollup.

When we write tests, we may want an easier way to access the local library we are testing or mocking libraries. We may also define aliases to counteract "require hell" and get rid of all those ../../../ imports we may have in the process.

For Webpack users: This is a plugin to have a resolve.alias functionality in Rollup.

Installation

npm install rollup-plugin-alias

Usage

import { rollup } from 'rollup';
import alias from 'rollup-plugin-alias';

rollup({
  entry: './src/index.js',
  plugins: [alias({
    somelibrary: './mylocallibrary'
  })],
});

An optional resolve array with file extensions can be provided. If present local aliases beginning with ./ will be resolved to existing files:

import { rollup } from 'rollup';
import alias from 'rollup-plugin-alias';

rollup({
  entry: './src/index.js',
  plugins: [alias({
    resolve: ['.jsx', '.js']
    foo: './bar',  // Will check for ./bar.jsx and ./bar.js
  })],
});

If not given local aliases will be resolved with a .js extension.
