@types/winston

What is @types/winston?

@types/winston provides TypeScript type definitions for the winston logging library, enabling developers to use winston with TypeScript and benefit from type checking and autocompletion.

What are @types/winston's main functionalities?

Basic Logging

This feature allows you to create a basic logger that logs messages to the console. The logger is configured with a logging level and a format.

const winston = require('winston');
const logger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  transports: [
    new winston.transports.Console()
  ]
});
logger.info('Hello, Winston!');

File Transport

This feature allows you to log messages to a file. The logger is configured with a file transport that writes logs to 'combined.log'.

const winston = require('winston');
const logger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  transports: [
    new winston.transports.File({ filename: 'combined.log' })
  ]
});
logger.info('Logging to a file!');

Custom Formats

This feature allows you to create custom log formats. The logger is configured with a custom format that includes a timestamp and a custom message format.

const winston = require('winston');
const { combine, timestamp, printf } = winston.format;
const myFormat = printf(({ level, message, timestamp }) => {
  return `${timestamp} [${level}]: ${message}`;
});
const logger = winston.createLogger({
  format: combine(
    timestamp(),
    myFormat
  ),
  transports: [
    new winston.transports.Console()
  ]
});
logger.info('Custom format log message');

This is a stub types definition for winston (https://github.com/winstonjs/winston.git).

winston provides its own type definitions, so you don't need @types/winston installed!
