How To: Debugging With Any User Account

The Debugging With Any User Account tutorial explains how to impersonate users without a password when debugging an app. Application framework allows easy overriding of the login mechanism. You will learn to ignore the password on the localhost address and how to use a master password to “unlock” any user account.

Offline App Step-By-Step

Code On Time offers a unique method of offline application development.

You begin by creating an online app instead. Put together a few data models and your application is ready to execute in any major web browser. You can even have it installed on your device to run natively.

Use the Project Designer to mark the data-aware pages as “offline”. This will enable the atomic data entry in the forms. Master and detail data items are persisted together when the top-level form is saved.

Next enable the Offline Sync Add-on, the optional component that brings about the magic. Users in the “Offline” role will see how the application front-end and account data are downloaded to the device as soon as they sign in. The front-end will look for the data in the local storage when performing the read and write operations. Users will have to explicitly sync their pending changes with the online back-end.

Learn to build offline apps with an online-first approach!

The installed app will also work in the offline mode without any distinguishable differences with the offline mode in a browser.

Custom User Login Responses

 The introduction of the 2-Factor Authentication in the application framework has required changes to the login process. The framework challenges the users to enter a verification code to confirm their identity. Method CreateUserLoginResponse(username, success)  in the ApplicationServices partial class creates the JSON object with the instructions for the client-side code when the verification is needed.

Developers can take advantage of the new method to provide custom responses informing the user about the remaining login attempts, locked account, and other special cases. Otherwise the framework displays a generic message “Your user name and password are not valid.”

The sample code below will let the user name if the account is locked or display a notification at the bottom of the screen. The code executes only if there is no login response created by the base implementation to avoid conflicts with the multi-factor authentication.

Invalid username or password will yield a notification message when the JSON object with the notify property is returned.

A more prominent response is provided if the responses includes the alert property.

If the event property is returned in the response, then the framework will raise the client-side event on the document object with the response passed as the args property of the event. 2FA implementation uses this method to pass extended information to the client library.
