Constants

const (
	ECONFLICT       = "conflict"
	EFORBIDDEN      = "forbidden"
	EINTERNAL       = "internal"
	EINVALID        = "invalid"

Application error codes.

These are meant to be generic and they map well to HTTP error codes.

Variables

var DefaultConfig = Config{
	Postgrest: PostgrestConfig{
		Version:   "v10.0.0",
		DBRole:    "postgrest_api",
		Port:      3000,
		AdminPort: 3001,
		MaxRows:   2000,
	},
}

Functions

func ErrorCode

func ErrorCode(err error) string

ErrorCode unwraps an application error and returns its code. Non-application errors always return EINTERNAL.

func ErrorData

func ErrorData(err error) string

ErrorMessage unwraps an application error and returns its message. Non-application errors always return "Internal error".

func ErrorDebugInfo

func ErrorDebugInfo(err error) string

ErrorDebugInfo unwraps an application error and returns its debug message.

func ErrorMessage

func ErrorMessage(err error) string

ErrorMessage unwraps an application error and returns its message. Non-application errors always return "Internal error".

func ErrorStatusCode

func ErrorStatusCode(code string) int

ErrorStatusCode returns the associated HTTP status code for an application error code.

func PrintableSecret

func PrintableSecret(secret string) string

func WriteError

func WriteError(c echo.Context, err error) error

func WriteSuccess

func WriteSuccess(c echo.Context, payload any) error

type Error

type Error struct {
	// Machine-readable error code.
	Code string

	// Human-readable error message.
	Message string
