PlugIns in 1999.io
Plugins in 1999.io are basically single-page apps that have access to the server, and can do things on behalf of the logged-in user.
Through lots of factoring over many months, the code is extremely high level.
We use Twitter for identity and the local server file system to store JSON files.
Very lightweight and low-tech but also quite powerful.
It’s all coming together nicely.
