Twitter's Effective Scala guide, a document distilling Twitter's experience and best practices for writing Scala in production, covering formatting, types, collections, concurrency, functional and object-oriented programming, and error handling. The repository contains the markdown source and build tooling (PEG markdown and groff) used to render and publish the guide to GitHub Pages.

Use cases

• learn Scala best practices from Twitter's production experience
• find recommended Scala style and formatting conventions
• understand how to use Scala futures and concurrency effectively
• decide which Scala features to embrace or avoid
• improve functional programming style in Scala
• onboard engineers to idiomatic Scala for high-volume services

When to choose

• you want concise, battle-tested guidance on writing effective Scala
• your team builds high-volume distributed services in Scala
• you need a reference for Scala idioms like Options, pattern matching, and case classes as algebraic data types
• you want a style guide to align a Scala codebase

When to avoid

• you need a tutorial for learning Scala from scratch
• you need up-to-date coverage of the latest Scala 3 features
• you want runnable code or a tool rather than a written guide
• you need an officially maintained specification rather than opinionated advice
