Package description
The connect npm package is a middleware layer for Node.js, designed to be used as a part of the 'http' module. It allows developers to create a series of middleware functions to handle requests and responses in a sequential manner. Connect is often used to set up middleware that can perform various tasks such as logging, parsing, session handling, and more.
Logging
This feature allows you to log every request that comes into the server with the method and URL.
const connect = require('connect');
const app = connect();
// Middleware for logging
function logger(req, res, next) {
console.log('%s %s', req.method, req.url);
next();
}
app.use(logger);
app.listen(3000);Static File Serving
This feature serves static files from a specified directory, in this case, 'public'.
const connect = require('connect');
const serveStatic = require('serve-static');
const app = connect();
app.use(serveStatic('public'));
app.listen(3000);Body Parsing
This feature allows you to parse the body of incoming requests in middleware before handling them.
const connect = require('connect');
const bodyParser = require('body-parser');
const app = connect();
app.use(bodyParser.json());
app.use(function(req, res) {
res.end(JSON.stringify(req.body));
});
app.listen(3000);Cookie Parsing
This feature allows you to parse cookies attached to the client request object.
const connect = require('connect');
const cookieParser = require('cookie-parser');
const app = connect();
app.use(cookieParser());
app.use(function(req, res) {
res.end(JSON.stringify(req.cookies));
});
app.listen(3000);Express is a web application framework for Node.js, built on top of connect. It extends connect's middleware model with additional functionality like routing, template engine support, and more. Express is more feature-rich and is considered a de facto standard for Node.js web applications.
Koa is a web framework designed by the creators of Express, aiming to be a smaller, more expressive, and more robust foundation for web applications and APIs. Koa uses async functions to eliminate callbacks and greatly increase error-handling capabilities. It does not bundle any middleware within its core, and it provides an elegant suite of methods that make writing servers fast and enjoyable.
Hapi is a rich framework for building applications and services. It enables developers to focus on writing reusable application logic instead of spending time building infrastructure. Hapi is known for its powerful plugin system and comprehensive API.
Restify is a Node.js web service framework optimized for building semantically correct RESTful web services ready for production use at scale. It is somewhat similar to Express but is more focused on enabling the building of correct REST web services.
Readme
Connect is a high performance middleware framework built by the combined forces of Tim Caswell (creationix) and TJ Holowaychuk (visionmedia) and the other skilled developers of ExtJS. Connect takes the familiar concepts of Ruby's Rack and applies it to the asynchronous world of node.
ExtJS is releasing Connect under the very liberal MIT license in hopes that we can provide some level of leadership and stability for application frameworks to build on.

To run the benchmarks you must have ApacheBench, and gnuplot installed, then:
$ make benchmark && make graphs && open results/graphs/*.png
First update the git submodules, which includes the Expresso TDD framework:
$ git submodule update --init
Then run the test suites located in ./test with the following command:
$ make test
Run a single test, or use a custom glob pattern:
$ make test TESTS=test/connect.test.js
