Effect is a powerful TypeScript library for building complex synchronous and asynchronous programs. Web application development often requires boilerplate code for tasks such as asynchrony, concurrency, state management and error handling. Effect-TS streamlines these processes using a functional programming approach. Leveraging TypeScript’s type system, Effect helps catch hard-to-detect issues at compile time. Our team previously used fp-ts for functional programming but found that Effect-TS provides abstractions that align more closely with daily tasks. It also makes code easier to combine and test. While traditional approaches like Promise/try-catch or async/await can handle such scenarios, after using Effect, our team found no reason to go back.
