Functions

func RespondWith

func RespondWith(c *gin.Context, status int, dataField interface{}, errMessage string, code ReturnCode)

RespondWith will respond with the generic API response

func RespondWithInternalError

func RespondWithInternalError(c *gin.Context, err error, innerErr error)

RespondWithInternalError should be called when the request cannot be satisfied due to an internal error

func RespondWithSuccess

func RespondWithSuccess(c *gin.Context, data interface{})

RespondWithSuccess should be called when the request can be satisfied

func RespondWithValidationError

func RespondWithValidationError(c *gin.Context, err error, innerErr error)

RespondWithValidationError should be called when the request cannot be satisfied due to a (request) validation error
