## Install
|
||
|
||
Using NPM:
|
||
```
|
||
$ npm install pino
|
||
```
|
||
|
||
Using YARN:
|
||
```
|
||
$ yarn add pino
|
||
```
|
||
|
||
If you would like to install pino v6, refer to https://github.com/pinojs/pino/tree/v6.x.
|
||
|
||
## 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"}
|
||
{"level":30,"time":1531171082399,"msg":"hello child!","pid":657,"hostname":"Davids-MBP-3.fritz.box","a":"property"}
|
||
```

## 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
|
||
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 [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.
|
||
|
||
### Bundling support
|
||
|
||
Pino supports being bundled using tools like webpack or esbuild.
|
||
|
||
See [Bundling](docs/bundling.md) document for more information.
