Effect, one function at a time

Six short lessons, one Effect function each, in the order I would teach them to a colleague.

Each lesson covers one function from Effect and shows it in a small TypeScript snippet. Read them in order; each one assumes the ones before it.

Lessons

1. 01
   Sequence steps with Effect.gen

   Write sequential Effect code with yield*.

2. 02
   Wrap a promise with Effect.tryPromise

   Turn a promise that can fail into an Effect.

3. 03
   Recover one error with Effect.catchTag

   Recover from one tagged error and leave the others alone.

4. 04
   Feed a layer with Layer.provide

   Feed one layer's output into another layer.

5. 05
   Stop waiting with Effect.timeout

   Stop waiting after a deadline.

6. 06
   Try again with Effect.retry

   Run the effect again after a failure.
