## Install
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ npm install pino
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Usage
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
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","v":1}
|
|||
|
|
{"level":30,"time":1531171082399,"msg":"hello child!","pid":657,"hostname":"Davids-MBP-3.fritz.box","a":"property","v":1}
|
|||
|
|
```

## Essentials
|
|||
|
|
|
|||
|
|
### Development Formatting
|
|||
|
|
|
|||
|
|
The [`pino-pretty`](https://github.com/pinojs/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⇗](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 – 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.
