presea

An utility function for bundling Node.js single executable applications.

From Node.js 20, it supports Single Executable Applications experimentally. This package integrates the binary bundle steps with unbuild following Single executable applications | Node.js v20.0.0 Document.

Installation

npm i -D presea

Usage

import { bundle } from 'presea'

await bundle('path/to/package')

CLI

This is working in progress.

npm i -g presea

echo "console.log('Hello')" > cli.js

presea cli.js

GitHub Actions

Here is an example GitHub Actions config to bundle single executable applications.

You should replace <bin> to your own binary name which is the same as your package.json or your build config.

name: Release

on:
  push:
    tags:
      - 'v*'

jobs:
  bundle:
    name: Bundle on ${{ matrix.target }}

    runs-on: ${{ matrix.os }}

    strategy:
      fail-fast: false
      matrix:
        include:
          - target: linux
            os: ubuntu-latest
            binary: ./dist/<bin>
          - target: windows
            os: windows-latest
            binary: .\dist\<bin>.exe

    steps:
      - uses: actions/checkout@v3

      - name: Setup pnpm
        uses: pnpm/action-setup@v2.2.4

      - name: Setup node
        uses: actions/setup-node@v3
        with:
          node-version: 20.x
          cache: pnpm

      - name: Install
        run: pnpm install

      - name: Build
        run: pnpm build  # now binary is located at matrix.binary

      # Upload to release and so on...

unbuild

Warning

Currently, SEA only supports for a single script, and can not require other node_modules.

But unbuild can not bundle the whole project into a single script.

See feat: unbuild bundle into a single script.

You should provide field bin in your package.json like the following config.

{
  "bin": {
    "hello": "./dist/hello.mjs"
  }
}

Import presea preset in your build.config.ts.

// build.config.ts

import { defineBuildConfig } from 'unbuild';

import { Sea } from 'presea/unbuild';

export default defineBuildConfig({
  preset: Sea(),
  // Your config...
});

Then, just run unbuild and the bundled single executable application is in your output directory.

$ npx unbuild

$ ./dist/hello world
Hello, world!

Development
