Middleware is the programming pattern of providing hooks with a resume callback.
Here's the basic usage of the file that you'll be creating:
var Middleware = require('./'); // <- this is the file you make;
var middleware = new Middleware();
middleware.use(function(next) {
var self = this;
setTimeout(function() {
self.hook1 = true;
next();
}, 10);
});
middleware.use(function(next) {
var self = this;
setTimeout(function() {
self.hook2 = true;
next();
}, 10);
});
var start = new Date();
middleware.go(function() {
console.log(this.hook1); // true
console.log(this.hook2); // true
console.log(new Date() - start); // around 20
});
