Console Capture

Send existing browser console output to Logged without replacing your normal console behavior.

Setup

import { Logged } from "@logged/sdk";

const logger = new Logged({
  apiKey: process.env.NEXT_PUBLIC_LOGGED_API_KEY!,
});

logger.interceptConsole();

After calling interceptConsole(), the following browser methods are forwarded to Logged while still appearing in DevTools:

• console.log
• console.info
• console.warn
• console.error

How it works

console.log("Application started");

console.info("User authenticated");

console.warn("API response is slow");

console.error("Payment failed");

Each call still prints to the browser console. Logged receives a structured copy with the log level, message, and serialized arguments.

Serialization

Console arguments are serialized safely so objects, arrays, and circular references do not break the SDK.

console.log("User:", {
  id: "123",
  role: "admin",
});

This produces a Logged event with the object preserved in metadata rather than stringified into [object Object].

Cleanup

logger.stopConsoleInterception();

Restores the original console methods. This is useful in tests or when disabling capture for part of an application lifecycle.
