I wrote my own middleware as module for my purposes that looks like the following:
-- myMiddleware.js
module.exports = {
fn1: function (req, res, next) {
console.log('fn1');
next();
},
fn2: function (req, res, next) {
console.log('fn2');
this.fn1(req, res, function () {
next();
});
}
};
In my sserver.js I use this middleware as the following:
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.cookieParser('your secret here'));
app.use(require('./myMiddleware').fn2);
Unfortunately that does not work because this context in fn2 in not myMiddleware.js object. How can use proper this?
You can't, the 'this' property will always be the vanilla Server (http.Server) instance or compatible handler.
You can do this:
var middlewares = {};
module.exports = middlewares;
middlewares.fn1 = function(req, res, next){ ... };
middlewares.fn2 = function(req, res, next){
middlewares.fn1(req, res, next);
};
