Modern, fast and lightweight Logger
Modern, fast, lightweight and generic logger. It's based on pino (https://www.npmjs.com/package/pino).
How to Install
npm install @diva.exchange/diva-logger
Getting Started - Usage
Use it either as
import { Logger } from '@diva.exchange/diva-logger'
Logger.trace('hello world')
or
const Logger = require('@diva.exchange/diva-logger')
Logger.trace('hello world')
API
diva-logger is static. It can be used without instantiation, like
import { Logger } from '@diva.exchange/diva-logger'
try {
throw new Error('A recoverable error')
} catch (error) {
Logger.warn(error)
// go on
}
diva-logger also attaches itself gently to the two global events uncaughtException and unhandledRejection. Hence an unhandled exception or an unhandled rejected promise will be properly logged (fatal):
import { Logger } from '@diva.exchange/diva-logger'
throw new Error('This is fatal')
After an unhandled exception or unhandled rejected promise, the process will be terminated with the exit code 1 (after the remaining event stack has been processed).
Chaining
diva-logger supports chaining, like
Logger.trace('trace message').debug('debug message')
Logging Examples, Usage of API
trace(any[, options])
Logger.trace('some trace message')
Logger.trace(process.env)
debug(any[, options])
Logger.debug(12345)
info(any[, options])
Logger.info('info goes here')
warn(any[, options])
Logger.warn('warning - recoverable error')
error(any[, options])
Logger.error('some serious error')
Logger.error(SomeObject)
fatal(any[, options])
Logger.fatal('One of the last messages of the process...')
