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.
