What is @types/pino?
@types/pino provides TypeScript type definitions for the Pino logging library, which is a fast and low-overhead logging library for Node.js applications.
What are @types/pino's main functionalities?
Basic Logging
This feature allows you to create a basic logger instance and log messages at the 'info' level.
const pino = require('pino');
const logger = pino();
logger.info('Hello, world!');
Custom Log Levels
This feature allows you to define custom log levels for more granular logging.
const pino = require('pino');
const logger = pino({
customLevels: {
foo: 35
}
});
logger.foo('This is a custom log level');
Child Loggers
This feature allows you to create child loggers that inherit properties from the parent logger.
const pino = require('pino');
const logger = pino();
const child = logger.child({ a: 'property' });
child.info('Hello from child logger');
Log Redaction
This feature allows you to redact sensitive information from logs.
const pino = require('pino');
const logger = pino({
redact: ['req.headers.authorization']
});
logger.info({ req: { headers: { authorization: 'secret' } } }, 'Request received');
