effect-log

Logging batteris for effect-ts.

Pretty logger

Use PrettyLogger.make to create the pretty logger or PrettyLogger.layer to
obtain a layer replacing the default logger. Optionally, these functions
accept an options object configuring what information gets
to the output.

``typescript
import { Effect, pipe } from "effect";
import { PrettyLog } from "effect-log";

import { exampleEffect } from "./example-logging-effect";

// These are the defaults. You can omit the argument
// completely if you're okay with the defaults.
const logger = PrettyLog.layer({
showFiberId: true,
showTime: true,
showSpans: true,
enableColors: true,
});

pipe(exampleEffect, Effect.provide(logger), Effect.runSync);
`

!pretty

JSON logger

Use JsonLogger.make to create the JSON logger or JsonLogger.layer to
obtain a layer replacing the default loggger. Optionally, these functions
accept an options object configuring what information gets
to the output.

`typescript
import { Effect, pipe } from "effect";
import { JsonLogger } from "effect-log";

import { exampleEffect } from "./example-logging-effect";

// These are the defaults. You can omit the argument
// completely if you're okay with the defaults.
const logger = JsonLogger.layer({
showFiberId: true,
showTime: true,
showSpans: true,
messageField: "message",
});

pipe(exampleEffect, Effect.provide(logger), Effect.runSync);
