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:
[pretty demo](pretty-demo.png)
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 are 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 [Transportsβ](docs/transports.md) 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 βΒ such as reduced requests per second.
In many cases, Pino is over 5x faster than alternatives.
See the [Benchmarks](docs/benchmarks.md) document for comparisons.
Bundling support
Pino supports being bundled using tools like webpack or esbuild.
See [Bundling](docs/bundling.md) document for more information.
