# Web Frameworks

Since HTTP logging is a primary use case, Pino has first class support for the Node.js
web framework ecosystem.

## Pino with Fastify

The Fastify web framework comes bundled with Pino by default, simply set Fastify's
`logger` option to `true` and use `reply.log` for log messages that correspond
to each individual request:

```js
const fastify = require('fastify')({
  logger: true
})
fastify.get('/', async (request, reply) => {
  reply.log.info('something')
  return { hello: 'world' }
})
```

The `logger` option can also be set to an object, which will be passed through directly
as the [`pino` options object](api.md#options).

Note: Fastify v1 uses [Pino v4](legacy.md#pino-v4-documentation). The upcoming Fastify v2 will use Pino v5.

See the [fastify documentation](https://www.npmjs.com/package/pino-http#pinohttpopts-stream) for more information.

## Pino with Express

```sh
npm install express-pino-logger
```

```js
const app = require('express')()
const pino = require('express-pino-logger')()

app.use(pino)

app.get('/', function (req, res) {
  req.log.info('something')
  res.send('hello world')
})

app.listen(3000)
```

See the [express-pino-logger readme](http://npm.im/express-pino-logger) for more info.

<a id="hapi"></a>
## Pino with Hapi

```sh
npm install hapi-pino
```

```js
'use strict'

require('make-promises-safe')

const Hapi = require('hapi')

async function start () {
  // Create a server with a host and port
  const server = Hapi.server({
    host: 'localhost',
    port: 3000
  })

  // Add the route
  server.route({
    method: 'GET',
    path: '/',
    handler: async function (request, h) {
      // request.log is HAPI standard way of logging
      request.log(['a', 'b'], 'Request into hello world')

      // a pino instance can also be used, which will be faster
      request.logger.info('In handler %s', request.path)

      return 'hello world'
    }
  })

  await server.register({
    plugin: require('.'),
    options: {
      prettyPrint: process.env.NODE_ENV !== 'production'
    }
  })

  // also as a decorated API
  server.logger().info('another way for accessing it')

  // and through Hapi standard logging system
  server.log(['subsystem'], 'third way for accessing it')

  await server.start()

  return server
}

start().catch((err) => {
  console.log(err)
  process.exit(1)
})
```

<a id="restify"></a>
## Pino with Restify

```sh
npm install restify-pino-logger
```

```js
const server = require('restify').createServer({name: 'server'})
const pino = require('restify-pino-logger')()

server.use(pino)

server.get('/', function (req, res) {
  req.log.info('something')
  res.send('hello world')
})

server.listen(3000)
```

<a id="koa"></a>
## Pino with Koa

### Koa

```sh
npm install koa-pino-logger
```

```js
const Koa = require('koa')
const app = new Koa()
const pino = require('koa-pino-logger')()

app.use(pino)

app.use((ctx) => {
  ctx.log.info('something else')
  ctx.body = 'hello world'
})

app.listen(3000)
```

<a id="http"></a>
## Pino with Node core `http`

```sh
npm install pino-http
```

```js
const http = require('http')
const server = http.createServer(handle)
const logger = require('pino-http')()

function handle (req, res) {
  logger(req, res)
  req.log.info('something else')
  res.end('hello world')
}

server.listen(3000)
```
