API reference

Everything the runtime binds into your scripts. All of it is available as a global, with no import.

Script	Script.loadClass, unload callbacks, runtime libraries, profiling hooks
$ magic imports	The shorthand Java class resolver
Modules: import and export	Sharing code between scripts, path resolution, reload cascades
Bukkit	The Bukkit server global and the platform helpers around it

Reacting to the server

Article	Covers
Commands	registerCommand, tab completion, aliases, middleware
Event listeners	registerListener and event priorities
Scheduler	Sync and async tasks, timers, cancellation
Concurrency model	What runs on which thread, and why loading blocks

Data and the outside world

Article	Covers
Database	The Sql module, queries and transactions
HTTP fetch	Calling external APIs
Console logging	log, warn, error
JSON	Parsing and serializing
Shared state and messaging	StaticStorage, GlobalMap, GlobalNotification, DataFile
Implementing Java interfaces	Handing a JavaScript implementation back to a Java plugin

The two you should read first

If you only read two articles here, make them Modules and the concurrency model. Between them they account for most of the bugs people hit in their first month.
