Use Claude to Write Go HTTP Handlers

Go's net/http patterns are consistent, but writing idiomatic handlers — with context propagation, structured errors, and clean JSON encoding — is repetitive. Claude nails the idioms.

claude "Write a Go HTTP handler for a POST /users endpoint. It should decode a JSON body, validate the required fields, insert into Postgres using pgx, and return appropriate status codes. Use the standard library only."

Claude will produce a handler that handles decode errors, validation, DB errors, and success responses cleanly — with no magic:

func (h *UserHandler) Create(w http.ResponseWriter, r *http.Request) {
    var req CreateUserRequest
    if err := json.NewDecoder(r.Body).Decode(&req); err != nil {
        http.Error(w, "invalid request body", http.StatusBadRequest)
        return
    }
    if req.Email == "" {
        http.Error(w, "email is required", http.StatusUnprocessableEntity)
        return
    }
    // ...
}

For router-specific patterns, be explicit about what you're using:

claude "Write a Chi router middleware that logs request duration and status code using slog. Apply it to all routes except /health."

Go rewards consistency — Claude delivers it every time.
