Start

Sinatra inspired web framework.

It has simple API to serve static files, handle dynamic requests, websockets and create JSON responses.

import 'package:start/start.dart';

void main() {
  start(port: 3000).then((Server app) {

    app.static('web');

    app.get('/hello/:name.:lastname?').listen((request) {
      request.response
        .header('Content-Type', 'text/html; charset=UTF-8')
        .send('Hello, ${request.param('name')} ${request.param('lastname')}');
    });

    app.ws('/socket').listen((socket) {
      socket.on('ping').listen((data) => socket.send('pong'));
      socket.on('pong').listen((data) => socket.close(1000, 'requested'));
    });

  });
}

API

start()

You start the server with start() function. It has 3 named arguments and returns Server future

Server

listen(host, port) // start the server (it's performed by the start function)
stop() // stops the server
get|post|put|delete(String route) // adds a handler, returns a Stream<Request>
ws(String route) // adds WebSocket handler, returns a Stream
static(String path, {bool jail, bool listing, bool links}) // serves static files from `path`, follows symlinks outside the root if jail is false

Routes

Route is a string with placeholders like :firstname its value is available through the Request param() method. Placeholders should start with colon :, if placeholder ends with a question mark ? it's optional. "/hello/:firstname.:lastname?" will match "/hello/john" and "/hello/john.doe"
