Algebraic Effects: From Research to Real-World Software Development

Algebraic effects are no longer a purely academic concept; they're a powerful tool for real-world software development. This article explores their key advantages: improved code testability, enhanced visibility into code behavior, and the ability to create custom control flow abstractions. Unlike monads, algebraic effects offer a more intuitive approach to managing side effects, yielding immediate benefits. Using Flix, a language with built-in support for algebraic effects, the article demonstrates practical applications, including handling exceptions, asynchronous operations, coroutines, generators, and backtracking search, culminating in a real-world AI movie recommendation app.
