Brief MEAN stack presentation.

2. Structure of presentation
•What is MEAN stack?
•Pros and Cons of using MEAN stack
•Show simple app

3. Structure of Web Application

4. Web Application

5. Front end vs Back end

6. Back end Front end
• Never visible to user What user interacts with
directly.
• Built with use of server side Interface between user and
language and database back end.

7. What is MEAN stack?

9. AngularJS
Our app’s entire front end
• Open source, maintained by Google
• Client side MVC (MVVM) framework
• Excellent data bindings
• Easy to test

10. Where to get Angular?
• Extremely lightweight – download/include only what you
need
https://docs.angularjs.org/misc/downloading

11. Node.js
Lightweight web server
• Built on Google Chrome’s V8 Javascript Engine
• Extremely lightweight and efficient
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello Worldn');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');

12. How to install Node.js
• http://nodejs.org/download/
• Prebuilt installers for Windows, OSX
• Use npm to install packages

13. Express
Creates our routes and our API
• “minimal and flexible node.js web application framework”
• Abstracts away a lot of low level logic
(e.g. for HTTP requests)
• Helps organize your Node app into an MVC structure

14. MongoDB
Our datastore
• The top NoSQL Database
• Open Source, maintained by MongoDB
• JSON like syntax
• Key-value stores

15. Finally

16. Advantages of MEAN stack
• there is no programming language to be used with the
MEAN stack other than the JavaScript.
• increases productivity and make ease debugging
• the objects stored in the database are identical to the
objects the client-side JavaScript deal with.
• Support MVC
• Fairly new and developing

17. Disadvantages
• MongoDB may work well for small to mid-sized apps,
but less so for large-scale applications (e.g 100′s of
millions of users).
