Proper error message sent from backend to client

[mittalyashu]

Store all types of error message in json format and send the response back based on the error type.

For example

module.exports = {
	SERVER_ERROR: {
		message: "Server error",
		statusCode: 500
	},
        USER_NOT_FOUND: {
		message: "User not found",
		statusCode: 404
        }
};

If you have suggestions for error messages based on the routes and controller we're using, please share them in comments below.
