What are @ui5/logger's main functionalities?

Basic Logging

This feature allows you to create a logger instance and log messages at different levels such as info and error.

const { getLogger } = require('@ui5/logger');
const log = getLogger('myLogger');
log.info('This is an info message');
log.error('This is an error message');

Custom Log Levels

This feature allows you to define custom log levels and use them in your application.

const { getLogger, createLogger } = require('@ui5/logger');
const customLogger = createLogger({
  transports: [
    new (require('@ui5/logger').transports.Console)({
      level: 'custom'
    })
  ]
});
const log = getLogger('customLogger');
log.custom('This is a custom log level message');

Custom Transports

This feature allows you to create custom transports for logging, such as logging to the console with a specific format.

const { getLogger, createLogger, transports } = require('@ui5/logger');
const customTransport = new transports.Console({
  level: 'info',
  format: require('@ui5/logger').formats.simple()
});
const customLogger = createLogger({
  transports: [customTransport]
});
const log = getLogger('customLogger');
log.info('This is an info message with a custom transport');
