Error Handling

Goroute provides out of the box global error handling. This is possible due to route handler func signature.

Each route handler requires this signature:

HandlerFunc func(Context) error

Which allows to directly return error from handler:

mux.GET("/user/:id", func(c Context) error {
    id := c.Param("id")
    if id == "" {
        return errors.New("id is empty")
    }
    if len(id) != 32 {
        return errors.New("id is invalid")
    }
    return c.NoContent(http.StatusOk)
})
