API
REST、GraphQL、gRPC 与 WebSocket。
Every app you use is a conversation between programs. When you open your feed, a client asks a server for posts and gets JSON back, and the rules of that conversation are an API. This track starts from zero: HTTP requests and responses, status codes, JSON, curl and fetch, then designing clean REST resources. After that you learn what makes developers love an API: safe keys and tokens, pagination, errors that help, rate limits, versioning and webhooks, and when to reach for GraphQL, gRPC or WebSockets instead.
Every example is a real HTTP exchange you can read line by line.
