func ReadJSON(w http.ResponseWriter, r *http.Request, dst any) error

ReadJSON reads and decodes JSON from the request body into the provided destination struct. It also performs various checks and returns detailed error messages for different types of JSON decoding errors.

func ReadUUIDPath(r http.Request) (uuid.UUID, error)

ReadUUIDPath extracts and parses a UUID from the request path, returning an error if the UUID is invalid.

func RespondWithJSON

func RespondWithJSON(w http.ResponseWriter, code int, payload interface{})

RespondWithJSON encodes the given payload to JSON and writes it to the response writer with the specified HTTP status code.

func WriteJSON

func WriteJSON(w http.ResponseWriter, status int, data models.Envelope, headers http.Header) error

WriteJSON encodes the given data to JSON with indentation and writes it to the response writer with the specified HTTP status code and headers.
