Development Setup
flarum/flarum is a "skeleton" application which uses Composer to download flarum/core and a bunch of extensions. In order to work on these, you will need to change their versions to dev-master
in composer.json
and install them from source:
$ composer update --prefer-source
Flarum's front-end code is written in ES6 and transpiled into JavaScript. The compiled JavaScript is only committed when we tag a release; during development you will need to do it yourself. To recompile the JavaScript you will need Node.js.
$ npm install -g gulp
$ cd vendor/flarum/core
$ ./scripts/compile.sh
Development tools
Most Flarum contributors use PHPStorm with an educational or open source license.
For serving a local forum, Laravel Valet (Mac), XAMPP (Win) and Docker-Flarum (Linux) are popular choices.
See also the First Read for Extension Developers and the great Flarum Development Workflow discussion.
What to work on
Check out the Roadmap and Milestones for an overview of what needs to be done. See the Good first issue label for a list of issues that should be relatively easy to get started with.
