heft-esbuild-plugin

• run esbuild from heft
• support rig packages

TODO

Watch mode is not implemented yet. currentlly taskDependencies is required to trigger build, otherwise it won't build at all in watch mode. normal build is ok.

Usage

1. add task in heft.json:

   	"esbuild": {
   		// "taskDependencies": ["typescript"], // you may need this
   		"taskPlugin": {
   			"pluginPackage": "@build-script/heft-esbuild-plugin",
   			"options": {
   				"any": "thing"
   			}
   		}
   	},

2. create config file config/esbuild.{ts,mts,cts,mjs,cjs,json} (no .js!)
3. write export options. example:

   /// <reference types='@build-script/heft-esbuild-plugin' />
   import type { BuildOptions, Plugin } from 'esbuild';
   export const options: BuildOptions[] = [
   	{
   		entryPoints: [{ in: './src/renderer.ts', out: 'renderer' }],
   		platform: 'browser',
   		outdir: './lib',
   		external: ['electron'],
   		plugins: [nodeSassPlugin()],
   	},
   	{
   		entryPoints: [{ in: './src/window/preload.ts', out: 'preload' }],
   		platform: 'node',
   		outdir: './lib',
   		define: { 'process.env.NODE_ENV': 'production' },
   		external: ['electron'],
   	},
   ];

session api

config script will have a globalThis.session object, which has type: IGlobalSession

This object will delete after script load, you must save a copy if you want to use it.

This is correct:

const session = globalThis.session; // save local copy for use
createEsbuildPlugin(session);
function after() {
	console.log(session.rootDir);
}

This is wrong:

function after() {
	console.log(session.rootDir); // Oops! session is gone
}

Write file hook

see: IOutputModifier

const session = globalThis.session; // save local copy for use
export function onEmit(files, options, lastReturn) {
	files[0].text = '/** xxx */' + files[0].text;
	files.push({ path: '/absolute/path.js', text: 'xxxxx' });
}

Note

Dependencies

You must install esbuild your-self.

If you use .ts as config file, typescript and ts-node is also required.

Depenency packages can be installed in rig package.

Settings

There are some default settings: see this file

Your config file override each options, not extend them. (except loader is extend)

Required options:

• outdir
• entryPoints

Deleted options: (throw if set)

• outfile
• absWorkingDir

Ignored options:

• write: handle by library
• metafile: force to true

ts-node

ts-node is registered if (and only if) config file is .ts. It will not unregister anymore.

If type field in package.json is module, you must create a config/package.json with content {"type":"commonjs"}.

You can create a config/tsconfig.json for ts-node.
