    Documentation

    Install

    $ npm install pino
    

    Usage

    const logger = require('pino')()
    
    logger.info('hello world')
    
    const child = logger.child({ a: 'property' })
    child.info('hello child!')

    This produces:

    {"level":30,"time":1531171074631,"msg":"hello world","pid":657,"hostname":"Davids-MBP-3.fritz.box"}
    {"level":30,"time":1531171082399,"msg":"hello child!","pid":657,"hostname":"Davids-MBP-3.fritz.box","a":"property"}

    Essentials

    Development Formatting

    The pino-pretty module can be used to format logs during development:

    Transports & Log Processing

    Due to Node's single-threaded event-loop, it's highly recommended that sending, alert triggering, reformatting and all forms of log processing is conducted in a separate process. In Pino parlance we call all log processors "transports", and recommend that the transports be run as separate processes, piping the stdout of the application to the stdin of the transport.

    For more details see our Transports⇗ document.

    Low overhead

    Using minimum resources for logging is very important. Log messages tend to get added over time and this can lead to a throttling effect on applications – such as reduced requests per second.

    In many cases, Pino is over 5x faster than alternatives.

    See the Benchmarks document for comparisons.
