JavaScript project management
Aegir is an opinionated tool for TypeScript/JavaScript project management, testing and release. You should use it if you just want to ship working code and have few strongly held opinions on linting, project layout and testing frameworks.
It bundles config for standard tools such as eslint, mocha, etc and lets you concentrate on writing code instead of formatting whitespace.
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.
.aegir.js
module.exports = {
tsRepo: true,
release: {
build: false
}
}
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.
Continuous Integration
Check this template for Github Actions https://github.com/ipfs/aegir/blob/main/md/github-actions.md
Testing helpers
In addition to running the tests aegir also provides several helpers to be used by the tests.
Check the documentation
Typescript
Aegir will detect the presence of tsconfig.json files and build typescript as appropriate.
Releases
aegir release will run semantic-release-style auto-releases with every change to main.
If you wish to batch changes up instead, please use release-please.
Config updates
You can keep your project configuration up to date by running:
$ npx aegir check-project
It will attempt to add/amend any configuration files that require updating to the latest versions.
If you have any custom config in your project please double check the edits it will make!
Install
$ npm i aegir
