UI State Storage & Cleanup

The state of the user interface in the apps built with Touch UI is maintained on the client. Authenticated users find the search criteria, filters, sort expressions, view styles, theme choice, and many other traces of their interactions with the app to be persisted between sessions. This makes it easy to pick up where you left off on the same device even when the browser window is closed and opened again. The app framework uses the local storage of the web view for this purpose. Each identity used to sign into the app will have its own UI state.

Touch UI can be configured to keep the user interface state in the session storage of the web view instead. The user interface state will persist while the browser window is open. App users start with the clean slate when the session is started in the new window.

Set the option ui.state.storage to session in ~/touch-settings.json configuration file to enable this behavior of the UI.


User identities and avatars are still persisted in the local storage to avoid having the user to sign in while moving between the app pages and browsing sessions. So are the global choices such as the theme and the presence of the sidebar.

Another related option allows controlling whether the user interface state is cleared when the user logs in or logs out. Option ui.state.clear is set to never by default. Developers may choose to clear the user-specific application state on the client upon logout. Value always will force the app to clear the UI state both on login and logout.

If the app is expected to be used on the shared devices, then setting the UI state storage to session and having it cleared always will eliminate any potential data exposure that can be exploited by the individuals with the physical access to the device. Recommend the end users to sign out and to close the browser or app when not in use.

Cloud On Time app executes the front end of the applications created with Code On Time from the locally stored HTML pages. Neither localStorage nor the sessionStorage objects are available in the web view. The entire set of local data specific to the user is removed from the device when the user signs out.

Touch UI application in the screenshot is running as the Progressive Web App and behaves just like the app in the web browser. It will retain the minimized sidebar, the data filter, and the reading pane mode when restarted by the user if the options ui.state.storage and ui.state.clear are not specified in the application configuration.

Cloud On Time for Windows 1.2.6
The new release of Cloud On Time for Windows 1.2.6 introduces the same host API that is presently available on iOS, Mac OS, and Windows 10.

It has also been verified with the upcoming Offline Sync Addon. This new product turns your online apps created with Code On Time into disconnected/offline applications. You don't have to write a single line of code to go completely offline!

Cloud On Time for iOS

We are putting final touches on Cloud On Time for iOS and will bring native apps based on Touch UI to your mobile devices made by Apple. The expected availability is end of June 2018.

Code On Time apps are running natively on mobile devices made by Apple.

Presently you can run your apps created with Code On Time in native mode on Windows 10 and Windows 7. Just install Cloud On Time from Microsoft App Store or from our own web site. Connect and start using your app in native mode right away. Soon you will be able to install Cloud On Time app from Apple App Store.

This screenshot shows Cloud On Time for iOS running in emulator with two apps connected. The frontends of the connected apps are installed on your mobile device and interact with the online backend to read/write data. Apps with Offline Sync Add-On will also download the data of offline pages and work in always disconnected mode. Offline data changes are synchronized with the online backend upon explicit user request.

Responsive nature of Touch UI makes the same app display correctly on a device with any screen size. The same app will run on the phones and tablets without a single change.

Your app created with Code On Time will feel “at home” on a native device from any maker.

The standard menu of app pages is displayed on the app home.    Page icons are presented as navigation tabs in Touch UI apps created with Code On Time.

Powerful input controls make it very easy to input data with the virtual and physical keyboards.

About Cloud On Time

Cloud On Time is the free app for iOS and Windows that will soon become available on OSX and Android platforms. One app allows connecting multiple custom online applications. The front end of each app runs locally on the device while sending requests to read/write data to its online backend.

Apps with Offline Sync Add-On will download their data as soon as the front end is installed. The front end works with the local data while creating a full log of change requests. Each request is “simulated” locally – the data is inserted, updated, and deleted from the end user prospective. Next synchronization will send the change log to the server and have it committed in the transaction scope to the database.

Use Cloud On Time to test the native mode of your app or run it in production mode to avoid the lengthy and slow approval cycles of app stores. Cloud On Time automatically detects the changes to the custom app front-end and installs the fresh components when the custom app is launched from the start page. Front end of offline/disconnected apps is automatically updated when the end user requests synchronization.

Custom Native Apps

Cloud On Time delivers a consistent native behavior across all major desktop and mobile operating systems on devices with the touch screens and those with the mouse pointers.

In July / August of 2018 the app generator will provide an option to download a custom native app for all major platforms.  App Store option becomes available as soon the app is published to the file system, FTP server, or major hosting provider. Custom Native App is a special version of Cloud On Time app capable of connecting to a single online backend only.

Developer will request a custom native app to be produced by providing the appropriate signing certificate and branding information. App generator will submit the request to our server. The server will generate a custom version of the Cloud On Time source code for the selected native platform and have it compiled. Developer will retrieve the binary package of the native app and submit it to the corresponding app store for approval.

App Store option allow requesting a custom branded version of the native app for the major platforms.

Custom Native App “knows” the URL of the published online version of the app created with Code On Time. In fact, this URL is baked into the app itself.

The app reads and writes data by making requests to the online backend. If Offline Sync Add-On is installed, then the native app will also work in offline/disconnected mode.

Developer can also choose to run their Code On Time application with “Custom App” client to test its behavior. The app generator will invoke the Windows version of the custom app on the development machine.

Code On Time developers can run the custom native app front end as the client during the development process.

See our roadmap for details.
