What is "MEAN" Stack?

Why "MEAN"?

OS Independence

Single-page-application (SPA)

One language on every stack

No discrete technologies

Tons of support - Node Modules

JSON for data transfer

Derived from the word humongous, MongoDB is a scalable and high-performance open source database designed to handle document-oriented storage

Stores data in JSON (internally BSON), providing a rich data model which maps to native programming language type with a dynamic schema

No ACID transactions, instead uses dynamic queries, sorting, rich updates, upserts, and aggregation

Interacting:

Mongo shell
Robomongo
Mongoose module

A series of middleware calls

Middleware: function with access to request and response objects, and the next in middleware in line request-response lifecycle

Events

Properties

Methods

Request

Response

Router

March 21, 2015

  app.get('/games/example/auth', auth.requiresLogin, function(req, res, next) {
    res.send('Only authenticated users can access this');
  });

Middleware

Executed in the order from left to right

Can be used to set a cookie, user's log status, etc.

Demo-II

Stale - but Yeoman for generators which does CRUD out of the box

Alternatives

MongoDB => CouchDB, RavenDB, Riak, Redis

AngularJS => React, EmberJS, Backbone, KnockoutJS, Drundal

Express => Hapi, Koa, Restify

NodeJS => I/O.JS

Conclusions

Frameworks are evolving, but JavaScript is here to stay. Keep investing - ES6 and beyond)
Make a judgement call:
- Write from scratch - hard work, struggle, fail, learn
- Start with a boilerplate framework - relatively easy to start, yet there are limitations
Participate in online communities
Have a side personal project
Stay on top of best practices - user groups, online forms and conferences are great for that
Practice and attend hackathons, hack nights as possible
Try out new things, innovate
