TypeScript definitions for bunyan
@types/bunyan provides TypeScript type definitions for the Bunyan logging library, which is a simple and fast JSON logging library for Node.js services.
Basic Logging
This feature allows you to create a basic logger and log messages at the 'info' level.
const bunyan = require('bunyan');
const log = bunyan.createLogger({name: 'myapp'});
log.info('Hello, world!');
Logging with Different Levels
This feature allows you to log messages at different levels such as trace, debug, info, warn, error, and fatal.
const bunyan = require('bunyan');
const log = bunyan.createLogger({name: 'myapp'});
log.trace('Trace message');
log.debug('Debug message');
log.info('Info message');
log.warn('Warn message');
log.error('Error message');
log.fatal('Fatal message');
Child Loggers
This feature allows you to create child loggers that inherit properties from the parent logger but can also have additional context-specific properties.
const bunyan = require('bunyan');
const log = bunyan.createLogger({name: 'myapp'});
const child = log.child({widget_type: 'foo'});
child.info('Hello from child logger');
Serializers
This feature allows you to use serializers to format log messages, such as including request and response objects in a structured way.
const bunyan = require('bunyan');
const log = bunyan.createLogger({name: 'myapp', serializers: bunyan.stdSerializers});
log.info({req: {method: 'GET', url: '/'}}, 'Request received');
Winston is another popular logging library for Node.js that supports multiple transports (e.g., console, file, HTTP) and log levels. It is more flexible in terms of output formats and transport options compared to Bunyan.
Pino is a very fast JSON logger for Node.js, similar to Bunyan. It focuses on performance and low overhead, making it suitable for high-throughput applications. Pino also provides a CLI tool for pretty-printing logs.
Log4js is a logging library inspired by the Java log4j library. It provides a variety of appenders for different output targets and supports hierarchical loggers. It is more feature-rich but can be more complex to configure compared to Bunyan.
