Tha 𝗔𝗣𝗜 Design 𝗛𝗮𝗻𝗱𝗯𝗼𝗼𝗸

 Here is the 𝟮𝟬𝟮𝟲 𝗔𝗣𝗜 𝗛𝗮𝗻𝗱𝗯𝗼𝗼𝗸 broken down by architecture:

𝟭. 𝗧𝗵𝗲 "𝗥𝗲𝗾𝘂𝗲𝘀𝘁-𝗥𝗲𝘀𝗽𝗼𝗻𝘀𝗲" 𝗧𝗿𝗶𝗼: This is synchronous. You ask, you wait. 

• 𝗥𝗘𝗦𝗧: Resource-centric. Uses standard HTTP verbs (GET, POST). Best for cacheable, stateless web services. 

• 𝗥𝗣𝗖 (𝗴𝗥𝗣𝗖): Action-centric. Treats network calls like local functions. Best for high-performance internal microservices. 

• 𝗚𝗿𝗮𝗽𝗵𝗤𝗟: Client-centric. The client defines the structure. Best for mobile apps to prevent over-fetching data.

𝟮. 𝗧𝗵𝗲 "𝗘𝘃𝗲𝗻𝘁-𝗗𝗿𝗶𝘃𝗲𝗻" 𝗧𝗿𝗶𝗼: This is asynchronous. The server pushes data when it's ready. 

• 𝗪𝗲𝗯𝗵𝗼𝗼𝗸𝘀: The "Reverse Request." The server calls your URL when an event happens. No polling required. 

• 𝗪𝗲𝗯𝗦𝗼𝗰𝗸𝗲𝘁𝘀: Persistent, Full-Duplex. The connection stays open for two-way chatter. Essential for gaming and chat. 

• 𝗛𝗧𝗧𝗣 𝗦𝘁𝗿𝗲𝗮𝗺𝗶𝗻𝗴 (𝗦𝗦𝗘): Mono-directional. The server pushes chunks of data down an open line. Great for news tickers.
