What is SPA ?

3.
–Microsoft
“Single-Page Applications are Web apps that load a single HTML page
and dynamically update that page as the user interacts with the app”

4.
Let the users have experience of desktop application on
using web pages.
Why SPA ?

5.
• Maintains application state.
• Help to bookmark and share.
• Keep the data and view in synchronization.
• Partial refresh
• Reduces static resource loading.
• Fast navigation between the application pages.
Advantages of SPA

6.
Server Side
Client Side
Types of SPA ?

7.
Server Side
Client Side
In early days Single Page application has developed fully in server
side with the help of Template engine. Business logic also written
in same programming language.
Ex: JSP, ASP, ERB, HBS
Now days Template engine got developed for client side rendering
and Half of the business logic has written in client side .

8.
• Write Less bugs
• Write Less vulnerable
• Organize application code
• Fast development
• Reusability
• Let focus more on business logic
• Fast development
• Reduces code review
Why framework ?

Libraries

12.
• Model
Application data.
• View
Elements which are going to be visible and interactive to user.
• State Container
Data which is going to represent state of the views
• Dispatcher / Observer Pattern
Helps to write loosely coupled code

13.
Development Utilities

14.
• Linting Tools
Helps to avoid mistakes when writing programs.
Example : ESLint , JSLint , JSHint and JSCS
• Code Transpiler for script
Let us write next generation code now that looks pretty-printed and readable.
Example : CoffeScript, Type Script, Bable JS, Live script
• Package manager
Tool for package management
Example : NPM, Bower, Yarn

15.
• Live reload / Hot reload
• Module Bundler
Helps to bundle all dependency files for production.
Example : browserify, webpack, requires JS
• CSS Preprocessors
A Scripting language for css that use to generate compiled regular CSS
Syntax.
Example : Sass, LESS

Framework
Choose
Make Own

17.
Framework after Architecture
Decide your Application architecture First

18.
Popular Architectures
• Model View Controller
Example : Angular, Ember
• Model View Viewmodel
Example : Knockout
• Model View Presenter
Example : Backbone , Riot
Note : Listed above architectures are frequently used not recommended for all types app*

19.
What is MVC ?
• Model
Business model
• View
Representing model and Handling DOM events
• Controller
Writing business logic

20.
What is MVVM ?
• Model

• Presenter
Representing UI with model.

22.
“All frameworks are not created for single solution and that might not
suite for our application.”
My thought 😉

23.
• Less to learn.
• Should be Straightforward to JavaScript.
• Framework size should not exceed application size.
