A lightweight Facebook library supporting the Graph, Marketing, and Atlas APIs, realtime updates, test users, and OAuth.
Koala is a Ruby wrapper for Facebook's Graph API, handling OAuth, batch requests, real-time update subscriptions, and test user management. It's for Ruby/Rails apps that need to read or write Facebook data. The abstraction layer is thin by design — you get back hashes and move on.
Batch API support is well-designed — the block-based DSL lets you consume results inline rather than unpacking a flat array afterward. Faraday as the HTTP layer means you can swap middleware, add logging, or tune timeouts without touching library internals. Rate limit header parsing is exposed both on errors and via a global hook, which is the right place to put it. Test infrastructure is unusually good — mock responses work out of the box, live tests run against test users, and VCR cassettes are included.
The README still advertises MRI 2.1–2.4, which is ancient; it's unclear without digging how current the actual supported version matrix is. The global configuration is explicitly documented as not threadsafe, which is a real problem in any multi-threaded Rails server. Facebook's API versioning has changed significantly since v2.0 days — there's no evidence the library tracks deprecations proactively, so you're likely to hit silent behavioral drift. Marketing and Atlas API support is mentioned prominently but the actual implementation surface for those is minimal compared to Graph.
