Aegir: JavaScript DevOps Automation Mastery

Aegir

JavaScript project management

Install

$ npm i aegir

Browser <script> tag

Loading this module through a script tag will make it's exports available as Aegir in the global namespace.

<script src="https://unpkg.com/aegir/dist/index.min.js"></script>

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 or src/index.ts.

All test files should be placed under test. Individual test files should end in .spec.js or .spec.ts 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 or test/node.ts should be used to require all node test files and the same thing for the other environments with a file named test/browser.js or test/browser.ts.

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"
}

Configuration

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

// file: .aegir.js

/** @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" : {
