Error Handling in WaveMaker App


WaveMaker platform, by default, takes care of the error handling for all the network calls being made by Variables and Widgets within an App.

Notification Action

By default, the errors are captured by a Notification Action called appNotification. This Action is created in the app by default, which is of error toaster type. Therefore, all the errors display as a red toaster, and these can be customized. If the messages does not apply, you can delete the appNotification variable.

tip

For more information about Toasters, see Toast in Notification Action.

Widgets do not use the appNotification action. Widgets by default, display error and success messages in the form of toaster.

You can customize these error messages. A common JavaScript error handler in app.js gets invoked once an error is captured by a Variable or a Widget. The signature of the error handler is explained below.

/*
* This application level callback function will be invoked after
* a Variable receives an error from the target service.
* Use this function to write common error handling logic across the application.
* errorMsg:  The error message returned by the target service.
*            This message will be displayed through appNotification variable
*            You can change this through $rootScope.Variables.appNotification.setMessage(YOUR_CUSTOM_MESSAGE)
* xhrObj:      The xhrObject used to make the service call
*              This object contains useful information like
*              statusCode, url, request/response body.
*/

App.onServiceError = function (errorMsg, xhrObj) {

};

Examples


Show custom message for all failures corresponding to HTTP status code

An app could a number of Variables hitting backend services. These services, in case of error, return an HTTP status code, for example, 400, 404, 500, and more. For example, to display a message for 404 error, use the onServiceError handler. In the following code snippet, see how to:

  1. Capture the error status of 404 from the xhrObj.status.
  2. Build a custom message.
  3. Use the setMessage method setting the message on the default notification variable.
App.onServiceError = function(errorMsg, xhrObj) {
        var custom_message;

        // logic to compute error message
        if (xhrObj.status === 404) {
            custom_message = 'Requested resource "' + xhrObj.url + '" not found. Please contact admin.';
        }

        // set message on the default notification variable
        App.Actions.appNotification.setMessage(custom_message);
    };

Log errors to a database table

Capture all service errors of an app and store it in a DB. Here, lvErrorLogs is the Variable corresponding to the table where error logs can be stored in a database. This table contains columns, including message, url, httpStatus and userid.

App.Variables.lvErrorLogs.insertRecord({
        row: {
            "message": errorMsg.message || errorMsg,
            "url": xhrObj.url,
            "httpStatus": xhrObj.status,
            "userid": App.Variables.loggedInUser.dataSet.id
        }
    });
