This document provides an overview of AngularJS including its advantages, uses, required tools, architecture, key concepts like directives, filters, dependency injection and services. AngularJS is a JavaScript MVC framework created by Google that focuses on the HTML side of web apps. It enhances HTML with directives, templates and bindings and is well-suited for single page apps. Development requires a code editor, browser and optional tools like NodeJS, GitHub, NPM and Gulp. The document outlines Angular's modular structure and core components like controllers, modules and scopes.
![Tools Required for
development
• Eclipse or Visual studio code (Code Editor)
• Google Chrome browser (Recommended browser)
• NodeJS (For client server) [Optional]
• GitHub (For accessing external repositories) [Optional]
• NPM, Bower (For managing 3rd party resources) [Optional]
• Gulp (Task runner) [Optional]](https://image.slidesharecdn.com/angularpatterns-170424070720/85/Angular-patterns-5-320.jpg)

- 2. What is AngularJS ? • AngularJS is a JavaScript MVC Framework created by Google. • Focus more on HTML side of web apps. • It deals everything within the browser, making it an ideal partner with any server technology • Angular supports hundreds of JavaScript components to integrate.
- 3. Advantages • Enhances HTML by attaching directives, custom tags, attributes, expressions, templates within HTML • Good for Single Page Applications (SPA) • Easy Data binding, Two way data binding • Re-usable Components • Dependency Injection • E2E Testing, Unit testing is easier
- 4. Where to use AngularJS ? • Single Page Applications • Dynamic Web Applications • RESTful applications • CRUD based applications • Mobile applications
- 5. Tools Required for development • Eclipse or Visual studio code (Code Editor) • Google Chrome browser (Recommended browser) • NodeJS (For client server) [Optional] • GitHub (For accessing external repositories) [Optional] • NPM, Bower (For managing 3rd party resources) [Optional] • Gulp (Task runner) [Optional]
- 8. LIFT Guideline Why LIFT ? Provides a consistent structure that scales well, is modular, and makes it easier to increase developer efficiency by finding code quickly. L – Locating our code easy I – Identify code at glance F – Flat structure as long as we can T – Try to stay dry
- 9. Application Structure Folders by Type Folders by Feature
- 10. Dependency Injection The process of injecting dependent functionality into modules at run time. Using an "constructor function". using an "injectable factory method"
- 11. Modules
- 13. Scopes and RootScopes • Scopes : Accessible inside only particular controller • RootScopes : Accessible through any controller
- 14. Controllers Controllers are the view handlers. Binds data into view using model
- 15. Services
- 16. Factories
- 18. Directives • Markers on a DOM element (such as arrtibute, element name, comment or css class) that tells angularJS HTML compiler ($compile) to attach a specific behaviour • It works via event listeners • It also capable to transform the DOM element and its children.
- 20. Filters • Filters format the value of an expression for display to the user • They can be used in view templates, controllers or services.
- 22. Angular Events
- 23. Dynamic views
- 24. UI Routing • UI-Router is a routing framework for AngularJS built by the Angular Team. • It changes your application views based on state of the application and not just the route URL.
- 25. Sample UI Routing template
- 26. API call using Angular Resource $resource was meant to retrieve data from an endpoint, manipulate it and send it back
