0http

0http

Cero friction HTTP framework:

• Tweaked Node.js Server for high throughput.
• The request router you like.

If no router is provided, it uses the find-my-way router as default implementation.

Usage

const cero = require('0http')
const { router, server } = cero()

router.on('GET', '/hello', (req, res) => {
  res.end('Hello World!')
})

router.on('POST', '/do', (req, res) => {
  // ...
  res.statusCode = 201
  res.end()
})

//...

server.listen(3000)

Routers

0http allows you to define the router implementation you prefer as soon as it support the following interface:

router.lookup = (req, res) // -> should trigger router search and handlers execution

find-my-way router

https://github.com/delvedor/find-my-way

This is the default router in 0http if no router is provided via configuration. Internally uses a Radix Tree router that will bring better performance over iterative regular expressions matching.

0http - sequential

This a 0http extended implementation of the trouter router. Includes support for middlewares and shortcuts for routes registration.
As this is an iterative regular expression matching router, it tends to be slower than find-my-way when the number of registered routes increases. However, tiny micro-services should not see major performance degradation.

Supported HTTP verbs: GET, HEAD, PATCH, OPTIONS, CONNECT, DELETE, TRACE, POST, PUT

const cero = require('0http')
const { router, server } = cero({
  router: require('0http/lib/router/sequential')()
})

router.use('/', (req, res, next) => {
  res.write('Hello ')
  next()
})

const routeMiddleware = (req, res, next) => {
  res.write('World')
  next()
}
router.get('/sayhi', routeMiddleware, (req, res) => {
  res.end('!')
})

server.listen(3000)

Async middlewares

You can user async middlewares to await the remaining chain execution:

router.use('/', async (req, res, next) => {
  try {
    await next()
  } catch (err) {
    res.statusCode = 500
    res.end(err.message)
  }
})

router.get('/sayhi', () => { throw new Error('Uuuups!') }, (req, res) => {
  res.end('!')
})

Servers

0http is just a wrapper for the servers and routers implementations you provide.

const cero = require('0http')

const { router, server } = cero({
  server: yourCustomServerInstance
})

Node.js http.Server

If no server is provided by configuration, the standard Node.js http.Server implementation is used.
Because this server offers the best balance between Node.js ecosystem compatibility and performance, we highly recommend it for most use cases.

Low Server

low is a tiny Node.js friendly wrapper around the great uWebSockets.js HTTP server. I/O throughput is maximized at the cost of API compatibility.

As far as for Node.js, uWebSockets.js brings the best I/O performance in terms of HTTP support.

Install dependencies

npm i uNetworking/uWebSockets.js#v15.11.0

Example usage

const low = require('0http/lib/server/low')
const cero = require('0http')

const { router, server } = cero({
  server: low()
})

router.on('GET', '/hi', (req, res) => {
  res.end('Hello World!')
})

server.listen(3000, (socket) => {
  if (socket) {
    console.log('HTTP server ready!')
  }
})


// ...
server.close()
