While using express in Node.js how to connect it with the client?
Do we need a .js file to be included in on the client side?
The goal is to make a client side with a "connec"t button and when I click that button the client is connected to the server and the server return is alerted on the page.
var app = require('express').createServer();
app.get('/', function(req, res){
res.send('hello world');
});
app.get('message', function(req, res){
console.log(req);
});
app.listen(3000);
Express is a web development framework (the intended client is a web browser).
In the application's root directory type node app.js and then open http://localhost:3000 in your browser
you can add jade file in the view folder and add the button to it and on click event , give the url to be called if that url matched with the app.get of the server code, do the work and after finishing render it back to the page u want with changes.
for rendering use res.render('index');
u can also pass results with it,
res.render('index',{result:result});
