kick.js

sinatra style routing framework

var app = kick();

app.use(function(req, res, next) {
    req.hello = 'hello world';
    next();
})

app.get('/', function(req, res, next) {
    res.end(req.hello);
})

app.get('/user/:userid', function(req, res, next) {
    res.end(req.params.userid + req.hello);
})

benchmark

benchmark with siege.js, constant routing has similar RPS with helloworld, param routing (30 param routing defined) lose 5% RPS.

node hello world [code]

GET:/  without cookie
    done:100000
    200 OK: 100000
    rps: 7495
    response: 0ms(min)	17ms(max)	1ms(avg)

GET:/user/30/abcdefg  without cookie
    done:100000
    200 OK: 100000
    rps: 7577
    response: 0ms(min)	17ms(max)	1ms(avg)

kick example [code]

GET:/  without cookie
    done:100000
    200 OK: 100000
    rps: 7411
    response: 0ms(min)	18ms(max)	1ms(avg)

GET:/user/30/abcdefg  without cookie
    done:100000
    200 OK: 100000
    rps: 7079
    response: 0ms(min)	17ms(max)	1ms(avg)

app.configure(env, fn)

app.use(middleware, ...)

app.configure('development', function(){
    app.use(connect.logger('dev'))
    app.use(connect.static(__dirname + '/public'))
    app.use(connect.cookieParser('tobo!'))
    app.use(connect.session());
});

app.get(path, middleware, ...)

Constant routing, O(1)

app.get('/about', routes.about);

Param routing, O(N)

app.get('/user/:userid', function(req, res, next) {
    res.end(req.params.userid);
});

Above will match /user/123 and req.params.userid is 123

Regular expression routing, O(N)

app.get(/^\/user-(\d+)$/, function(req, res, next) {
    res.end(req.params[1])
});

Above will match /user-123 and req.params[1] is 123

N = count(params routing) + count(regular expression routing)
