Bundlers integration

• parcel
• rollup
• vite
• webpack

parcel

Supports of exports map is provided under a flag, therefor packages relying only on this mechanism will not be resolved unless the flag is activated.

To activate the exports map resolution you must add this configuration in your package.json

{
  "@parcel/resolver-default": {
    "packageExports": true
  }
}

rollup

rollup does not provides much auto-configuration, fortunately there are plugins to do what we need to achieve.

• commonjs interoperability => @rollup/plugin-commonjs
• modules resolution => @rollup/plugin-node-resolve

Here are the steps to follow:

• Install the following dev-dependencies:

npm i --save-dev @rollup/plugin-commonjs @rollup/plugin-node-resolve

• Configure rollup.config.mjs:

import { nodeResolve } from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';

export default {
  input: 'src/index.js',
  output: {
    file: 'dist/bundle.js',
    format: 'esm',
  },
  plugins: [
    nodeResolve({
      preferBuiltins: false,
      browser: true,
    }),
    commonjs(),
  ],
};

vite

Bundling iexec with vite should run out of the box.

webpack

Bundling iexec with webpack@5 should run out of the box.
