The document provides an overview of the MEAN stack, which is a full-stack JavaScript solution for building web applications. It consists of MongoDB (a NoSQL database), Express (a Node.js web application framework), AngularJS (a client-side framework), and Node.js (a JavaScript runtime). The document discusses each component, how they work together, advantages like using a single programming language throughout and ability to build fast applications, and disadvantages like MongoDB not being as robust as SQL databases. It concludes that MEAN provides a fast, easy way to create modern, responsive dynamic web sites.
MEAN Stack is a full-stack JavaScript solution that helps you build fast, robust and maintainable production web applications using MongoDB, Express, AngularJS, and Node.js.
MEAN Stack technology is a full-stack JavaScript solution that helps you build fast and very light weight web application. The web application made under MEAN stack is fast because the Node js which is run time environment made by C++ which is very fast as compare to other languages.
MEAN is acronym of Mongodb, Express js, Angular js, Node js. The MEAN stack technology is very easy to learn because MEAN is completely based on JavaScript which means you don't have to learn different languages for implementing this.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. Agenda
• Introduction
• What isLAMP?
• Requirements for amodernweb
• What isMEAN?
• What isMongoDB?
• What isExpress?
• What is AngularJS?
• What isNode.JS?
• Disadvantages of MEANSTACK
• Conclusion
• Any Questions?
3. Introduction
• MEAN is an opinionated
framework which simplifies
full stack JavaScript
and accelerates web
application development.
• MEAN represents a major shift in architecture and
mental models — from relational databases to
NoSQL and from server-side Model-View-Controller
to client-side, single-pageapplications.
• MEAN is an acronym for Mongo DB, Express
JS,Angular JSand Node.Js.
4. What is LAMP ?
• Linux
• Apache
• MySQL
• PHP
• LAMPstack is apopular open source web platform commonly
used to run dynamic web sites andservers.
• It includes Linux,Apache, MySQL,and PHP/Python/Perl andis
considered by many the platform of choice for development
and deployment of high performance web applications which
require asolid and reliable foundation.
5. Problems with LAMP?
• Apache is not the fastest web serveraround
• It’s hard to write good-to-read, reusable and fastPHP
code
• Frontend works with other languages thanthe
backend
• Toomany conversions (XMLto PHPto HTML,model
to SQL)
• There is no separated server-side and client-side
development
6. Requirements for a
modern web?
• Customers want fast web sites/fast responsetimes
• No page reloads
• Enterprises want to govirtual
o Onebox +Severalvirtual images =>Shared Hardware
o Systemwith minimal memory footprint/overhead needed
• Asmany concurrent requests aspossible
• Only load resources when needed (conditional
loading)
• Mobile/Responsive UIs
7. What is MEAN Stack?
MEAN Stack is a full-stack JavaScript solution that
helps you build fast, robust and maintainable
production web applications using MongoDB, Express,
AngularJS,and Node.js.
8. • 100%free , 100%Open Source
• 100%JavaScript (+JSONandHTML)
• 100%Web Standards
• Consistent Models from the backend to the frontend and back
• Useauniform language throughout your stack
o JavaScript(the language of the web)
o JSON(the data format of theweb)
o No conversion needed for the database
• UseJavaScriptwith agreat framework (compared to jQuery)
• Allows to start with the complete frontend development first
• Very low memoryfootprint/overhead
11. What is MongoDB
• Developed by software company 10gen (now
MongoDB Inc.)
• FastNoSQLschemaless database written inC++
• Document-Oriented Storage
o JSON-styledocuments with dynamicschemas
• Full Index Support
o Index on anyattribute
o Replication & HighAvailability
• Auto-Sharding
o Scalehorizontally without compromisingfunctionality
17. Advantages And
Disadvantages
Advantages
• Lightening fast.
• Auto sharding.
• Replication is very easy.
• Youcanperform rich queries, cancreate on the fly
indexes with asingle command.
Disadvantages
• Very unreliable
• Indexes take up alot of RAM.
o B-tree indexes
18. Express JS
Expressis aminimal and flexible node.js web
application framework, providing arobustset of
features for building singleand multi-page, and hybrid
web applications.
19. What is Express ?
• Node JSbased webframework
• Basedon connect middleware
• Makesusageof Node JSeveneasier
• Easyto implement RESTAPI
• Easyto implement sessionmanagement
• Supports several template rendering engines (Jade,EJS)
o Supports partials -> soyou cansplit your HTMLin
fragments
• Asynchronous
• Implements MVCpattern
20. Express – What is it?
• Allows to set up middlewares to respond to HTTP
Requests.
• Defines arouting table which is used to perform
different action based on HTTPMethod and URL.
• Allows to dynamically render HTMLPagesbased on
passingarguments to templates.
21. Example
var express=require('express');
var app =express();
app.get('/', function (req,res)
{
res.send('Hello World!'); });
app.listen(3000, function ()
{
console.log('Example app listening on port 3000!');
});
22. Advantages And
Disadvantages
Advantages
• Regardlessof complexity, there should be veryfew
roadblocks if you know JavaScriptwell.
• Supports concurrency well.
• Fastand the performance is comparable with Golang
micro frameworks and Elixir's Phoenix.
Disadvantages
• There is no built in error handlingmethods.
23. What is Angular?
AngularJSis an open-sourceJavaScript
framework, maintained byGoogle,that assists with
running single-page applications.
• Its goal is to augment browser-based applications
with model–view–controller (MVC) capability, in an
effort to make both development andtestingeasier.
24. AngularJS
• JavaScriptframework developed by Google
• Basedon Model-View-* Pattern (client-side)
o MVC/MVVM
o Bi-Directional DataBinding
• Declarative Programming (focus on what – not thehow!)
o Directives are integrated in HTMLdirectly
o DOMManipulations completely hidden
• Great for Frontenddevelopment
o Great for SPA(Single PageApplications)
o Great for mobileapps
• Very modular and extensible
o Makestesting an ease
• Great Browser support (>IE8)
• Well documented
26. AngularJs directives
• ng-app
o Declares an element as a root element of the application
allowing behaviour to be modified through custom HTML
tags.
• ng-bind
o Automatically changesthe text of aHTMLelement tothe
value of agivenexpression.
• ng-model
o Similar to ng-bind, but allows two-way data bindingbetween
the view and thescope.
• ng-controller
o Specifies aJavaScriptcontroller classthat evaluates HTML
expressions.
27. AngularJs directives
• ng-repeat
o Instantiate an element once per item from acollection.
• ng-show& ng-hide
o Conditionally show or hide an element, depending onthe
value of abooleanexpression.
• ng-switch
o Conditionally instantiate one template from aset ofchoices,
depending on the value of aselectionexpression.
• ng-view
o Thebasedirective responsible for handling routes that
resolve JSONbefore rendering templates driven by specified
controllers.
29. Node JS
Node.js is aplatform built on Chrome'sJavaScript
runtime for easily building fast, scalablenetwork
applications.
• Node.js usesan event-driven, non-blockingI/O
model that makesit lightweight andefficient,
perfect for data-intensive real-time applicationsthat
run acrossdistributed devices.
30. What is Node JS?
• Written in C/C++
o Canalso useClibraries
• Built on top of Chrome’s V8engine – sopure
JavaScript!
o Therefore based on latest ECMAScript5
• Framework to build asynchronous I/Oapplications
• SingleThreaded – no concurrency bugs– no
deadlocks!
o Not internally though – but we’ll get to that
• Onenode process =one CPUCore
31. What is Node JS continue
• Caneasily handle 10k concurrent connections
o Doesn’t have any problems with concurrency
o Doesn’t create much overhead (CPU/Memory)
• Easilyscalable (just create acluster)
• Very fast (well, it’s mostly Ccode)
• Installation and first server start within lessthan5
minutes
o REST-APIthat replies to GETrequests canbe
implemented in lessthan 5 minutes aswell!
• It’s not awebframework!
35. Disadvantages of mean
Stack
• There are still no general JScodingguidelines
• MongoDB is not asrobust asan SQLserver
o Thissecurity is what they sacrifice to gain speed
• Onceyou’ve created the first site with this
technology, it’s hard to go back tothe old approach
36. Conclusion
In the end, Mean is a full stack, Javascript, web
application framework. If you require a fast, easy,
simple way to create a modern, responsive, dynamic
web site then MEANwould be agreat solution.
