Faye

Faye is a set of tools for dirt-simple publish-subscribe messaging between web clients. It ships with easy-to-use message routing servers for Node.js and Rack applications, and clients that can be used on the server and in the browser.

See faye.jcoglan.com for documentation.

Questions, issues, ideas

Please raise questions on the mailing list: groups.google.com/group/faye-users, and feel free to announce and share ideas on Faye-related projects here too. I’d appreciate it if we only use the GitHub issue tracker for bona fide bugs; You’ll probably get better and quicker answers to questions from the mailing list.

Development

To hack on Faye, you’ll need Ruby in order to build both the Gem and the NPM package. There are also a few submodules we use for testing. The following should get you up and running:

# Download the code from Git
git clone git://github.com/faye/faye.git
cd faye
git submodule update --init --recursive

# Install dependencies
bundle install
npm install

# Build Faye
bundle exec jake

# Run tests
bundle exec rspec -c spec/
node spec/node.js

# Install Ruby gem
gem build faye.gemspec
gem install faye-x.x.x.gem

# Install NPM package
npm install build

To-do

Notification API:

Notify listeners of network drop-out (may be transport dependent)
Provide reflection API for internal stats on channels, subscriptions, message queues
(Maybe) build a monitoring GUI into the server

Sugar:

Add sugar for authentication extensions for protected subscribe + publish

Missing protocol features:

Provide support for user-defined /service/* channels
Let local server-side clients listen to /meta/* channels
