Note: Angular is Component Based.

1. Factory : It is a set of values and functions.

It uses a single call mechanism.

We have to create an object every time to access

any function.

2. Service : It is a set of factories.

It uses singleton mechanism.

Object is created only for first request and the same

object is used for other requests.

3. Component : It comprises of

a) Presentation in HTML

b) Styles in CSS

c) Logic in Typescript

d) Pre-defined business logic from services.

4. Directive : A directive is responsible for making static DOM

into Dynamic DOM.

A directive is responsible for extending HTML.

Angular is completely decoupled from DOM manipulations.

A directive can return HTML.

a) Return HTML

b) Extend HTML

c) Make HTML more Interactive

5. Pipes : A pipe is used to transform data.

6. Routing : It is a technique used in angular to handle

navigation.

SPA navigation depends on Routing.

7. State Management: HTTP is a state less protocol.

State Management allows to store data and

handle across requests.

a) Session State

b) Application State

c) Cookies etc..

8. Security : Application Level Security

- CORS

- XSS

- Cross Page Posting

- Injection Attacks

9. Module : It is a combination of directives, services,

factories, pipes etc.
