Effect Module Console

Owned scope

• Owns only effect/Console.
• Source of truth: packages/effect/src/Console.ts.

What it is for

• The Console module provides a functional interface for console operations within the Effect ecosystem. It offers type-safe logging, debugging, and console manipulation capabilities with built-in support for testing and environment isolation.

• log
• info
• time
• warn
• clear
• count

• Full API list: references/api-reference.md

How to use it

• Use the reference docs to select the smallest API surface that solves your task.
• Validate behavior against existing tests before introducing new usage patterns.

Starter example

import { Console, Effect } from "effect";

// Basic logging
const program = Effect.gen(function* () {
  yield* Console.log("Hello, World!");
  yield* Console.error("Something went wrong");
  yield* Console.warn("This is a warning");
  yield* Console.info("Information message");
});

Common pitfalls

• Concurrency helpers can hide ordering/cancellation behavior; test interruption and race paths.
• Prefer explicit, typed combinators over ad-hoc casting or unchecked assumptions.

Not covered here

• Adjacent modules in effect/* and effect/unstable/* are out of scope for this owner.

Escalate to

• effect-skill-router for routing and ownership checks.
