README

🐼 HTTPanda - a frugal HTTP server for simple tasks

  • Lightweight and fast
  • Streamlined feature set, sufficient for most applications
  • Supports express (and connect) compatible middleware
  • Both CommonJS and ES module support via tsukuru

Basic usage

import { Server } from 'httpanda';
import cors from 'cors';

const server = new Server();
server.use(cors())
      .get('/hello', (req, res) => res.end('Hello World!'))
      .get('/users/:id', (req, res) => res.end(`Welcome, user ${req.params.id}!`))
      .listen(3000).then(() => console.log('Listening on port 3000')).catch(e => console.error(e));

Reference

new Server(options?: ServerOptions)

Creates a new instance of HTTPanda.

All options are optional, you can just use new Server() to use the default options.

Available options:

server

Your own HTTP server instance. Can also take a https.Server to support SSL.

onError

An error handler that takes the following arguments:

  • e - the error object
  • req - the request object (an instance of the internal Request type)
  • res - the response object (an instance of the internal Response type, currently equivalent to http.ServerResponse)
  • next - a function you can call to ignore the error and keep walking the middleware chain

Example

const server = new Server({
    server: https.createServer({ /* ... certificate stuff ... */ }),
    onError: (e, res) => {
        console.log(e);
        res.statusCode = e.code || 500;
        res.end(JSON.stringify(e));
    }
})

server.listen(port: number): Promise<this>

Listens to the given port. The returned Promise resolves with the Server instance on success, or rejects in case the port is in use or could otherwise not be bound.

Other forms of this as shown in the node net documentation are also supported, except the callback is always replaced by the returned Promise.

server.use(...callbacks: RouteCallback[]): this

server.use(path: string, ...callbacks: RouteCallback[]): this

Chains a set of middlewares on the given path, or on any path if none is given. Express middlewares are supported!

server.add(method: string | undefined, path: string, ...callbacks: RouteCallback[]): this

Adds a callback to a specific path. Parameters can be specified on the path with a leading colon and are available on req.params:

server.get('/users/:id', (req, res) => res.end(`Welcome, user ${req.params.id}!`))

If you pass undefined as method, the callback will execute on any method.

server.all(path: string, ...callbacks: RouteCallback[]): this

A shortcut to server.add(undefined, path, ...callbacks).

server.get(path: string, ...callbacks: RouteCallback[]): this

A shortcut to server.add('GET', path, ...callbacks).

Other shortcuts that work the same way:

  • server.head
  • server.options
  • server.post
  • server.put
  • server.patch
  • server.delete
  • server.connect
  • server.trace
