Automated JavaScript project management.

Project Structure

The project structure when using this is quite strict, to ease replication and configuration overhead.

All source code should be placed under src, with the main entry point being src/index.js.

All test files should be placed under test. Individual test files should end in .spec.js and will be ran in all environments (node, browser, webworker, electron-main and electron-renderer). To run node specific tests a file named test/node.js should be used to require all node test files and the same thing for the other environments with a file named test/browser.js.

Your package.json should have the following entries and should pass aegir lint-package-json.

"main": "src/index.js",
"files": [
  "src",
  "dist"
],
"scripts": {
  "lint": "aegir lint",
  "release": "aegir release",
  "build": "aegir build",
  "test": "aegir test",
  "test:node": "aegir test --target node",
  "test:browser": "aegir test --target browser"
}

Examples:
  aegir build                                   Runs the build command to bundle JS code for the browser.
  npx aegir build                               Can be used with `npx` to use a local version
  aegir test -t webworker -- --browser firefox  If the command supports `--` can be used to forward options to the underlying tool.
  npm test -- -- --browser firefox              If `npm test` translates to `aegir test -t browser` and you want to forward options you need to use `-- --` instead.

Use `aegir <command> --help` to learn more about each command.

Configuration

Aegir can be fully configured using a config file named .aegir.js or the package.json using the property aegir.

// file: .aegir.js

'use strict'

/** @type {import('aegir').PartialOptions} */
module.exports = {
  tsRepo: true,
  release: {
    build: false
  }
}

// file: package.json
"main": "src/index.js",
"files": [
  "src",
  "dist"
],
"scripts": {
  "lint": "aegir lint",
  "release": "aegir release",
  "build": "aegir build",
  "test": "aegir test",
  "test:node": "aegir test --target node",
  "test:browser": "aegir test --target browser"
},
"aegir" : {
  "tsRepo": false
}

You can find the complete default config here and the types here.
