About

Brewski is a tiny node framework that assists in the creation of performant APIs when other options feel like overkill.

Features

• Fast: being perfomant is a must
• Extendible: supports express style middleware
• Logging: build in logger
• Environment Management: simple handling of enviroment variables with envobj
• Chainable: API is completely chainable

Install

$ npm install brewski
# OR
$ yarn add brewski

Usage

const brewski = require('brewski')

const app = brewski({
  env: {
    port: 8888
  }
})

const { log, env } = app

app.use((req, res, next) => {
  log.info({ url: req.url })
  next()
})

// Middleware with error
// app.use((req, res, next) => {
//   next(new Error('Should be error'))
// })

// http://localhost:8888
app.get('/', (req, res) => {
  res.send('Hi from brewski')
})

// http://localhost:8888/json
app.get('/json', (req, res) => {
  res.send({ test: true })
})

// http://localhost:8888/status/tiaan
app.get('/status/:name', (req, res) => {
  res.status(201).send({ name: req.params.name })
})

// http://localhost:8888/query?name=Tiaan
app.get('/query', (req, res) => {
  res.send({ name: req.query.name })
})

// http://localhost:8888/html
app.get('/html', (req, res) => {
  res.html('<h1>Hi</h1>')
})

// http://localhost:8888/redirect
app.get('/redirect', (req, res) => {
  res.redirect(`http://localhost:${app.env.port}/`)
})

app.listen(app.env.port)

API

brewski(options): Object

Creates and returns a new brewski object.

Options include:

• logLevel: String - Level of logging for pino logger. Defaults to info.
• logStream: Stream - Stream to log to. Defaults to process.stdout.
• env: Object - Environment variables to pass to envobj.
• https: Object - Configuration options if https server should be created. Uses same options as http.createServer
• defaultHandler: function - Function to handle act as default route e.g.:

  function defaultHandler(req, res) {
    res.statusCode = 404
    res.end()
  }

Example:

const brewski = require('brewski')
const api = brewski({
  logLevel: 'fatal',
  env: {
    port: 3000
  }
})

brewski.use(middleware: Function): Object

Add new middleware to the stack. Middleware is processed in the order they are added. Since the middleware function matches that of express, existing packages can be used with no additional configuration:

const brewski = require('brewski')
const api = brewski()

const helmet = require('helmet')

api.use(helmet())

brewski.route(method: String|Array, route: String, handler: Function)

Creates a new route. Brewski uses find-my-way to handle routing and supports parametric, wildcard and parametric with regex routes e.g:

const brewski = require('brewski')
const api = brewski()

api.get('/foo/:baz', (req, res) => {
  res.send(req.params)
})

api.get('/baz/*', (req, res) => {
  res.send(req.params)
})

api.get('/baz/:thing(^\\d+).png', (req, res) => {
  res.send(req.params)
})

Shorthand Methods

You can also use the shorthand methods to declare your routes e.g:

const brewski = require('brewski')
const api = brewski()

function handler(req, res) {
  res.send({success: true})
}

api.get('/foo', handler)
api.post('/foo', handler)
api.patch('/foo', handler)
api.delete('/foo', handler)
api.head('/foo', handler)
api.put('/foo', handler)
api.option('/foo', handler)

api
  .get('/baz', handler)
  .post('/baz', handler)

brewski.server

Access to the HTTP server instance created by brewski. See node docs for more information.

brewski.listen(port, address, callback)

Starts the created server on provided port and address. If port is not provided, env.PORT is used. callback is called after server starts listening.

Example:

const brewski = require('brewski')
const api = brewski()

api.listen()
// api.listen(3000)
// api.listen(3000, () => console.log('Listening on port 3000'))

brewski.log

Provides access to the pino logger instance e.g:

const brewski = require('brewski')
const api = brewski()

api.log.info({foo: true})

See pino documentation for more options.

brewski.env

Provides access to envobj object.
