Package: effect
Module: Logger

Logger.pretty

The pretty logger utilizes the capabilities of the console API to generate visually engaging and color-enhanced log outputs. This feature is particularly useful for improving the readability of log messages during development and debugging processes.

Example

import { Effect, Logger } from "effect"

const program = Effect.log("message1", "message2").pipe(
  Effect.annotateLogs({ key1: "value1", key2: "value2" }),
  Effect.withLogSpan("myspan")
)

Effect.runFork(program.pipe(Effect.provide(Logger.pretty)))
//         green --v                      v-- bold and cyan
// [07:51:54.434] INFO (#0) myspan=1ms: message1
//   message2
//    v-- bold
//   key2: value2
//   key1: value1

Signature
