    Documentation

    Install

    $ npm install pino
    

    If you would like to install pino v6, refer to https://github.com/pinojs/pino/tree/v6.x.

    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 be conducted in a separate process or thread.

    In Pino terminology we call all log processors "transports", and recommend that the transports be run in a worker thread using our pino.transport API.

    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.

    Bundling support

    Pino supports to being bundled using tools like webpack or esbuild.
