Dynamic import support in acorn

This is plugin for Acorn - a tiny, fast JavaScript parser, written completely in JavaScript.

For more information, check out the proposal repo.

Usage

You can use this module directly in order to get Acorn instance with plugin installed:

import acorn from 'acorn-dynamic-import';
// or...
const acorn = require('acorn-dynamic-import').default;

Or you can use inject.js for injecting plugin into your own version of Acorn like this:

const acorn = require('acorn-dynamic-import/lib/inject').default(require('./custom-acorn'));

Then, use the plugins option whenever you need to support dynamicImport while parsing:

const ast = acorn.parse(code, {
  plugins: { dynamicImport: true }
});

To use the updated walk functionality the process is similar. You can require the default implementation as:

import walk from 'acorn-dynamic-import/lib/walk';
// or...
const dynamicImportWalk = require('acorn-dynamic-import/lib/walk').default;

Or you can use the injectable version for injecting the new walk functionality into your own version of Acorn like this:

import { inject } from 'acorn-dynamic-import/lib/walk';
import acornWalk from 'acorn/dist/walk';

const walk = inject(acornWalk);
