Forces Influencing the View
• Marketing - Trend to ‘native’ like apps UX
• Performance - Offload some of the work to the client
• Business - Web applications need more hits to make a $

The View Evolution
What makes it possible?• Improved browser JS performance• Improved client hardware• HTML 5 Standards
text
Move to Single Page Applications
Single Page App
Result:• We get a “Standalone” Client• The “V” in server MVC almost disappears• Client becomes more complex• Asset management importance hits a new peak• Both server and client become more robust

Move all presentation logic to the client

Basic Architecture text
New Web Client Complexities
• Lots of assets (JS, CSS, HTML, Images)
• Lots of 3rd party libraries
• Lots of events and logic
• Complex data models and logic
• State management
• Routing management
text
Introducing Web Client Development
text
Web Apps Development Keys
• Start treating web apps with respect (as software)
• Adopt standard development flows and tools
• Test your code
• Separation of concerns and concise modules
• Manage assets with designated tools
• Use dependency management tools
text
The Web Dev Toolkit
text
Yeoman
• Project Scaffolding• Code Generation
text
Grunt
• JS Task executor• Used for:
○ JS & CSS file concatenation andminification
○ Asset versioning○ Code linting○ CSS - Sass, Less, Compass○ HTML optimisation○ Test execution○ Many many more…
text
Bower
• Client dependency manager
text
Summary
• Web apps should be treated as software
• Web Client should be developed as a separate
project
• Coding paradigms (MVC) should be applied to web
apps
• Use tools to increase efficiency
