This is a collection of items, each specifying one general rule, to help you write RxJava code more effectively. It is modeled after two of my favorite technical books, Effective C++ and Effective Java. I appreciate not only the soundness of their contents, but the brevity of their writing style. I hope that Effective RxJava has the same value proposition.

For each rule I've attempted to provide relevant example code -- most of which is currently in production in the Khan Academy Android app.

• Use Retrolambda
• Emit immutable values
• Understand Observable and observer chains
• Convert functions to Observable
• Convert callbacks to Observable
• Understand subscribeOn and observeOn
• Understand switchMap
• Test emitted values using TestObserver
• Test work scheduling using TestScheduler
• Use compose for operator sequences
• Optimize your subscribers
