What's a RESTful API? Here's a dead-simple guide:
————
Representational State Transfer (REST) is an architectural style that is commonly used for web-based APIs alongside HTTP as the transport protocol.
𝗞𝗲𝘆 𝗰𝗼𝗻𝗰𝗲𝗽𝘁𝘀:
🔹 𝗦𝘁𝗮𝘁𝗲𝗹𝗲𝘀𝘀: The server shouldn’t need to store any information about a user between requests. Everything that the server needs to execute a task should be sent in the request.
🔹 𝗦𝗲𝗽𝗮𝗿𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝗰𝗼𝗻𝗰𝗲𝗿𝗻𝘀: The client and server should function independently of each other.
🔹 𝗖𝗮𝗰𝗵𝗲𝗮𝗯𝗹𝗲: Responses can be cached on the client to boost performance.
🔹 𝗖𝗼𝗻𝘀𝗶𝘀𝘁𝗲𝗻𝘁 𝗶𝗻𝘁𝗲𝗿𝗳𝗮𝗰𝗲: By using HTTP methods like GET, POST, and DELETE, API interfaces stay consistent.
🔹 𝗥𝗲𝘀𝗼𝘂𝗿𝗰𝗲-𝗯𝗮𝘀𝗲𝗱: RESTful APIs have an emphasis on resources rather than methods or functions. A resource can be an object, entity, or data within a system. Resources are uniquely identified using a Uniform Resource Identifier (URI).
🔹 𝗦𝘁𝗮𝗻𝗱𝗮𝗿𝗱 𝗺𝗲𝗱𝗶𝗮 𝘁𝘆𝗽𝗲𝘀: Responses are usually sent as JSON, XML, or plain text. Clients can request a preferred media type.
By providing guidelines like statelessness, separation of concerns, and standardized interfaces, REST has made it easier to develop scalable, stable, high-performing applications.
