Orbiter Versus OrbiterMicro
At only 10k gzipped, OrbiterMicro delivers a stripped down, yet full-fledged realtime communications system in a tiny package. OrbiterMicro is perfect for mobile devices and bandwidth-limited environments. For larger projects, where a slightly larger download is acceptable (49k gzipped) , use Orbiter instead of OrbiterMicro. Orbiter provides a much more extensive API that is easier to use and faster to develop with than OrbiterMicro.
OrbiterMicro's API is directly interchangeable with Orbiter's API, so it's trivial to upgrade a project from OrbiterMicro to Orbiter. OrbiterMicro is, in fact, a subset of Orbiter; both are compiled from the exact same core code.
The complete code for the chat is shown below. For a direct API comparison, see the Orbiter version of the chat.
