Definition
- REST stands for REpresentational State Transfer. It’s an architectural style for providing standards between computer systems on the web.
- REST compliant systems are called RESTful systems
Key Features
- Separation of Client and Server
- Code on the client side doesn’t affect the server and vice-versa
- Statelessness
- server doesn’t need to know the state the client is and vice versa
Communication between Client and Server
- HTTP Verbs more in CRUD
- GET - retrieve a specific resource or collection of resources
- POST - create new resource
- PUT - update a specific resource (by id)
- DELETE - remove a specific resource by id
- Headers and Accept parameters
- In the header, an
Accept field defines the type of content that the client is able to receive from the server
- These types of content are called MIME Types
- Ex.
application/json, image/png
- Sending responses
content-type header field alerts the client what type of content is being sent (look above at MIME Types)- Response codes (reference link)
