Together, let's build amazing PHP forum software.

I’m Toby Zerner, the developer of esoTalk. Years ago, I built esoTalk as a fresh, lightweight forum software alternative. esoTalk is nice but it is not built on a sustainable foundation.

As it stands, there is a need for modern, well-architected, powerful forum software that is easy to use and self-host. That’s what Flarum is. But I'm a full-time student and I don't have time to do this by myself. So I'm opening up Flarum to the world — let's build it together.

Philosophy

I have a vision for Flarum — one that has grown over years of playing with forums, developing esoTalk, and learning from mistakes. It is captured by the following four points:

• Modern design. Beautiful, clean, customizable. Forum design hasn’t evolved with the rest of the web; let's finally bring it up to speed.
• Unopinionated feature-set. Every community is different, and forum software should be able to adapt to — rather than define — how a community is run. As such, Flarum will have a lightweight core, and most features will be implemented as optional extensions.
• High performance. Flarum should perform well on scales big and small, and on a large range of devices.
• Sustainable architecture. Flarum should be built for the future, on a strong foundation which can evolve with the technologies that power it.

Flarum is open-source software released under the MIT license.

Technology

I've carefully considered which frameworks to use to build Flarum. Here's the reasoning:

Laravel

PHP remains the most user-friendly language for deploying web scripts, especially on shared hosting. The Laravel framework will allow for rapid development of Flarum’s API, and has a large community which will encourage collaboration and evolution.

Ember.js

Ember.js is a mature JavaScript framework which will power Flarum’s front-end. Use of a JavaScript framework allows us to build a fast, dynamic interface which feels more like an app than a simple web page.

Don't like the fact that Flarum is an Ember.js app? Take a look at FluxBB 2, which is being developed in a more traditional manner with Laravel.

Current State

Take a look at the live demo to see Flarum in action.

For a general overview of where Flarum is headed, read this blog post.

In short, the priority at the moment is to build out a lightweight core, and only start building Extensions when it is relatively stable.

For a full list of planned features, see Features.

Installation

Currently Flarum is in its very early stages, and it isn’t pretty. It is far from usable. Set it up only if you know what you’re doing, and expect it to break a lot.

1. Install Vagrant and VirtualBox.

2. Clone the Flarum skeleton app and set up the Vagrant box:

   git clone https://github.com/flarum/flarum.git
   cd flarum
   vagrant up
   

3. SSH into the Vagrant box and compile the Ember app:

   vagrant ssh
   cd /vagrant/flarum/core/ember && ember build
   

4. Add the following to your /etc/hosts file:

   192.168.29.29 flarum.dev

5. Visit flarum.dev in a browser.

If you’re having trouble, do not create a new issue — instead, get help on the Flarum Development Forum or hop on the IRC channel (#flarum on irc.freenode.net).

Contributing

Building Flarum is going to be a team effort, and we'd love for you to help! All contributions are welcomed.

What Can I Do?

• Contribute code. Start by becoming familiar with Flarum's source code and its Architecture. Then have a look at what needs to be done in the list above, and see if there's anything you can help out with. See below for instructions on submitting a Pull Request.

• Participate in discussion. Review the wiki and issues and contribute your constructive thoughts. We'd also love to hear general feedback on the Flarum Development Forum, on IRC (#flarum on irc.freenode.net), and on Twitter.

• Spread the word. Know someone who could help out? Please share this project with them!

Process

1. Review the Flarum Contributor License Agreement. (Why?)

2. Install Flarum as detailed in the instructions above.

3. Create a new branch.

   git checkout -b new-flarum-branch
   

   Please implement only one feature/bugfix per branch to keep pull requests clean and focused.

4. Code.

   • Follow the coding style: PSR-2.
   • Include tests and make sure they pass (subject to #3 and #4).

5. Commit.

   • Commit messages are required.
   • They should include a short description of the changes on the first line, then a blank line, then more details if necessary.

6. Clean up. Squash together minor commits.

   git rebase -i
   

7. Update your branch so that it is based on top of the latest code from the Flarum repository.

   git fetch origin
   git rebase origin/master
   

8. Fork your repository on GitHub and push to it.

   git remote add mine git@github.com:<your user name>/flarum.git
   git push mine new-flarum-branch
   

9. Submit a pull request.

   • Go to the Flarum repository you just pushed to (e.g. https://github.com/your-user-name/flarum).
   • Click "Pull Request".
   • Write your branch name in the branch field.
   • Click "Update Commit Range".
   • Ensure that the correct commits and files changes are included.
   • Fill in a descriptive title and other details about your pull request.
   • Click "Send pull request".

10. Respond to feedback.

    • We may suggest changes to your code. Maintaining a high standard of code quality is important for the longevity of this project — use it as an opportunity to improve your own skills and learn something new!

Core Team

Currently the only person on the core development team is Toby Zerner (@tobscure). Over time, judged by display of commitment to the project, and quantity/quality of contributions, I will be looking for more people to join the core development team. Please do not email me asking to be on the core team; rather, demonstrate initiative and commitment to the project, and I will more than likely notice!
