sequenz
sequenz composes connect middleware for nodejs
sequenz makes a single middleware from multiple middlewares
install
npm install sequenz
use
a middleware is a function of three arguments:
the request object req from the nodejs http server,
the response objectres from the nodejs http server
and a callback next.
middleware handles the request and usually modifies the response.
if a middleware doesn't end the request it should call next to give control
to the next middleware.
the sequenz module exports a single function. that function either takes a single array of middlewares or any number of middlewares as separate arguments. it returns a new middleware that will call those middlewares in order.
example
the example uses some connect middleware and passage for routing.
var http = require('http');
var connect = require('connect');
var sequenz = require('sequenz');
var passage = require('passage');
var routes = sequenz(
passage.get('/', function(req, res, next) {
res.end('landing page');
}),
passage.get('/about', function(req, res, next) {
res.end('about page');
})
);
var middleware = sequenz(
function(req, res, next) {
console.log('i am a middleware that is called first on every request');
next();
},
connect.favicon(),
connect.bodyParser(),
connect.cookieParser(),
connect.query(),
routes,
function(req, res, next) {
res.statusCode = 404;
res.end('not found');
}
);
var server = http.createServer(middleware);
server.listen(8080);
