These are extensions that allow facil.io to easily implement HTTP and Websocket services. Please read the project's README.md for more details, or visit facil.io's website.
Notice: these extensions require the core facil.io library, including it's fiobj core type system. Websockets will also require the pubsub service in order for pub/sub to work. The Redis extension can be used to scale pub/sub beyond a single machine.
