ESBuild Velcro Plugin

This esbuild plugin uses Velcro to build projects without having to npm install dependencies.

This Plugin wires up Velcro with esbuild so that bare module

Example

Given a project with the following file structure:

package.json:

{
  "dependencies": {
    "react": "~17.0.1",
    "react-dom": "~17.0.1"
  }
}

index.jsx:

import * as React from 'react';
import * as ReactDOMServer from 'react-dom/server';

const Hello = () => <h1>Hello world</h1>;

export function render() {
  return ReactDOMServer.renderToString(<Hello />);
}

Configure esbuild to build this project without ever having to npm install react or react-dom...

build.js:

import { build } from 'esbuild';
import { createPlugin } from 'esbuild-plugin-velcro';

(async () => {
  const result = await build({
    bundle: true,
    define: {
      'process.env.NODE_ENV': JSON.stringify('development'),
    },
    entryPoints: ['.'],
    plugins: [createPlugin({ target: 'node' })],
  });
})();

Usage

createPlugin(options)

Returns an instance of this plugin where options is an optional object having:

• .extensions is an optional array of extensions to support resolving files without explicit extensions.
• .packageMain is an optional array of supported 'main' fields. Options:
  • browser - Note that the browser field's extended resolution and overrides semantics are supported
  • module
  • jsnext:main
  • main
  • unpkg
• .target is an optional value describing the target runtime environment for the build. Options:
  • node - When this is specified, Node's built-in modules will be treated as esbuild externals, and therefore not bundled.
