AEgir

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 setup files for the node and the browser should be test/node.js and test/browser.js respectively.

Your package.json should have the following entries.

"main": "src/index.js",
"scripts": {
  "lint": "aegir-lint",
  "release": "aegir-release",
  "build": "aegir-build",
  "test": "aegir-test",
  "test:node": "aegir-test node",
  "test:browser": "aegir-test browser",
  "coverage": "aegir-coverage",
  "coverage-publish": "aegir-coverage publish"
}

Stack Requirements

To bring you its many benefits, aegir requires

• JS written in Standard style
• Tests written in Mocha
• Karma for browser tests

Tasks

Linting

Linting uses eslint and standard with some custom rules to enforce some more strictness.

You can run it using

$ aegir-lint
# or as gulp task
$ gulp lint

Testing

You can run it using

$ aegir-test
# or as gulp task
$ gulp test

There are also browser and node specific tasks

$ aegir-test node
$ gulp test:node
$ aegir-test browser
$ gulp test:browser

If you want to run tests in a webworker you can also pass --webworker as a flag to enable that.

If the needed environment variables are set, tests are also run on [Sauce Labs]. You will need

• $SAUCE=true
• SAUCE_USERNAME=<username>
• SAUCE_ACCESS_KEY=<access key>

Fixtures

Loading fixture files in node and the browser can be painful, that's why aegir provides a method to do this. For it to work you have to put your fixtures in the folder test/fixtures, and then

// test/awesome.spec.js
const loadFixture = require('aegir/fixtures')

const myFixture = loadFixture(__dirname, 'fixtures/largefixture')

If you write a module like interface-ipfs-core which is to be consumed by other modules tests you need to pass in a third parameter such that the server is able to serve the correct files.

For example

// awesome-tests module
const loadFixture = require('aegir/fixtures')

const myFixture = loadFixture(__dirname, 'fixtures/coolfixture', 'awesome-tests')

// tests for module using the awesome-tests
require('awesome-tests')

// .aegir.js file in the module using the awesome-tests module
'use strict'

module.exports = {
  karma: {
    files: [{
      pattern: 'node_modules/awesome-tests/test/fixtures/**/*',
      watched: false,
      served: true,
      included: false
    }]
  }
}

Coverage

You can run it using

$ aegir-coverage
# or as gulp task
$ gulp coverage

To auto publish coverage reports from Travis to Coveralls add this to your .travis.yml file. For more details see node-coveralls.

script:
  - npm run coverage

after_success:
  - npm run coverage-publish

Building

This will build a browser ready version into dist, so after publishing the results will be available under

https://unpkg.com/<module-name>/dist/index.js
https://unpkg.com/<module-name>/dist/index.min.js

You can run it using

$ aegir-build
# or as gulp task
$ gulp build

Specifying a custom entry file for Webpack

By default, aegir uses src/index.js as the entry file for Webpack. You can customize which file to use as the entry point by specifying entry field in your user configuration file. To do this, create .aegir.js file in your project's root diretory and add point the entry field to the file Webpack should use as the entry:

module.exports = {
  entry: "src/browser-index.js",
}

Webpack will use the specified file as the entry point and output it to dist/<filename>, eg. dist/browser-index.js.

If .aegir.js file is not present in the project, webpack will use src/index.js as the default entry file.

Releasing

1. Run linting
2. Run tests
3. Build everything
4. Bump the version in package.json
5. Generate a changelog based on the git log
6. Commit the version change & CHANGELOG.md
7. Create a git tag
8. Run git push to upstream/master
9. Publish a release to Github releases (if GH_TOKEN is available)
10. Publish to npm

# Major release
$ gulp release --type major
$ aegir-release --type major
# Minor relase
$ gulp release --type minor
$ aegir-release --type minor
# Patch release
$ gulp release
$ aegir-release

You can also specify a --env for a release, which can be either 'node', 'browser' or 'no-build'.

$ aegir-release --env node
$ gulp release --env node

You can generate a changelog for all versions by using --first

$ aegir-relase --first

You can skip all changelog generation and the github release by passing in --no-changelog.

If you want documentation generation you can pass --docs to the release task to build documentation and publish it to the gh-pages branch.

Documentation

You can use aegir-docs to generate documentation. This uses documentation.js with the theme [https://github.com/dignifiedquire/clean-documentation-theme].

To publish the documentation automatically to the gh-pages branch you can run

$ aegir-docs --publish
