pino

✓ import pino from 'pino'

Pino supports both ESM imports and CommonJS `require()` syntax.

Initializes a Pino logger and demonstrates basic info logging and creating a child logger with additional properties.

import pino from 'pino'; const logger = pino(); logger.info('hello world'); const child = logger.child({ a: 'property' }); child.info('hello child!');

Debug

Known issues

breakingPino v10 drops support for Node.js 18.

fix

Upgrade your Node.js runtime to version 20 or newer, or stick to Pino v9.x.

affects: >=10.0.0

breakingThe type signature for the `censor` function used in redaction has been updated for improved safety, potentially causing TypeScript errors or runtime issues if using previous, less safe types.

fix

Review and update your `censor` function implementations to match the safer type definitions introduced in v10.1.0. Consult the official Pino redaction documentation for guidance.

affects: >=10.1.0

gotchaWhen using Pino transports in worker threads, certain Node.js monitoring tools or `--import` preload options can lead to `ERR_WORKER_INVALID_EXEC_ARGV` errors or memory leaks.

fix

Ensure your Pino version is at least 10.3.1 for fixes related to `NODE_OPTIONS` sanitization and `ERR_WORKER_INVALID_EXEC_ARGV`. Avoid using `--import` preloads with transports if possible, or consult Pino transport documentation for recommended practices.

affects: >=10.0.0

gotchaPino's transport level filtering behavior might not be immediately intuitive. Logs are filtered by the transport's level, not necessarily the parent logger's level.

fix

Explicitly configure transport levels if you require specific filtering. Refer to the 'Transports' documentation for detailed examples on level filtering.

affects: >=10.3.1

Errors

Common errors & fixes

ERR_WORKER_INVALID_EXEC_ARGV

Using Pino transports in worker threads with specific monitoring tools or `NODE_OPTIONS` preload configurations.

fix

Upgrade to Pino v10.2.1 or newer. Ensure Node.js environment variables (like `NODE_OPTIONS`) are correctly sanitized or avoid conflicting preload settings when using worker-based transports.

TypeError: Argument of type '...' is not assignable to parameter of type '(...)'

Pino v10.1.0 introduced stricter type definitions for the `censor` function signature, leading to TypeScript compilation errors for older, less safe implementations.

fix

Adjust the signature of your `censor` function to align with the updated, safer types provided by Pino v10.1.0 and later. Consult the Pino redaction documentation for the correct signature.
