2. API (Application Programming Interface)
The API layer acts as the middleman between your frontend and backend.
It defines how software components talk to each other. REST, GraphQL, gRPC, and even good old SOAP are all protocols you can use here. Sometimes you’ll also use WebSockets for real-time updates.
In essence, the API is the translator that helps your frontend say, “Hey, I need the user’s data,” and the backend understands and responds with it.
