esbuild-plugin-peg

This plugin lets you import PEGjs and Peggy files when bundling with Esbuild

Installation

npm install --save-dev esbuild-plugin-peg

or

bun add -D esbuild-plugin-peg

Getting Started

my.peggy

start = a:[0-9] "+" b:[0-9] { return a + b; }

main.js

import * as parser from './my.peggy'

console.log(parser.parse("1+2"))

build.js

const peg = require('esbuild-plugin-peg');

require('esbuild').build({
  entryPoints: ['main.js'],
  bundle: true,
  outfile: 'out.js',
  plugins: [peg()],
});

If you are using bun, you can activate the plugin as follows:

peg-loader.ts

import { plugin } from 'bun'
import peg from 'esbuild-plugin-peg/bun'

await plugin(peg())

You can then activate the loader per default in your project via

preload = "./peg-loader.ts"
