• Constants
• func DecodeJSON(w http.ResponseWriter, r *http.Request, target any) error
• func LimitedBody(w http.ResponseWriter, r *http.Request, maxBytes int64) io.ReadCloser
• func WriteJSON(w http.ResponseWriter, status int, data any)

Constants

const MaxRequestBodySize = 1 << 20

MaxRequestBodySize is the maximum allowed request body size (1MB). This prevents memory exhaustion attacks via large payloads.

Functions

func DecodeJSON

func DecodeJSON(w http.ResponseWriter, r *http.Request, target any) error

DecodeJSON decodes JSON from the request body into the target. It uses LimitedBody to prevent oversized payloads.

func LimitedBody

func LimitedBody(w http.ResponseWriter, r *http.Request, maxBytes int64) io.ReadCloser

LimitedBody wraps a request body with a size limit. Returns a ReadCloser that will return an error if the body exceeds maxBytes.

func WriteJSON

func WriteJSON(w http.ResponseWriter, status int, data any)

WriteJSON writes a JSON response with the given status code. It sets the Content-Type header to application/json.
