TypeScript has a comprehensive flow and is, without a doubt, great. But it is missing a standard library like those available for other languages.
Primitives like concurrency, execution suspending/interruption, retries, data decoding/encoding, caching, queues, etc., are possible in TypeScript but challenging to put together.
Many NPM libraries may provide those functionalities, but every library usually has a different API design. The time has come, and we may finally have a library that aims to solve this and many other TypeScript problems. Its name is Effect. Let’s dive deeper into it and check if this is our TypeScript silver bullet.
We will talk about:
- Effect & its main advantages
- Creating a simple Effect base application
- Using basic Effect primitives like pipes and generators
- Wrapping existing code with Effect
- Handling errors and dependency injection in Effect
- Using type-safe data decoding and encoding using @effect/schema
- Fetching type-safe JSON data from REST API
- Creating HTTP server with Effect
- Accessing SQL database with Effect
- Using Effect in React Applications
- Adding observability/telemetry to Effect applications.
