The Tabris.js Developer App

The Tabris.js Developer App is the easiest way to see some Tabris.js examples and to start developing mobile apps without having to perform an app build. It is available for free in the app stores – just follow the links below or search for “Tabris.js” in the store on your mobile device. (The app “Tabris.js 2” is for legacy Tabris.js 2.x projects only, “Tabris.js” is always the current version.)

The Developer Tools

In the developer tools toolbar at the top, you’ll find an URL input text field and a Reload action that loads and starts the running script from scratch. In the overflow menu your find the Home action which lets you go back to the Developer App (on Android you can also press the back button). You’ll also find the actions to clear, filter and share the log.

While running Tabris.js scripts in the Developer App, you can open the log console by tapping on the “console” button in the developer tools toolbar at the top. In it you’ll see messages and errors logged by the running script. You can also enter JavaScript expressions that will be evaluated in the context of your script, for example tabris.device.platform.

Play with the Playground

To get started with Tabris.js development easily, try out the Playground, our online code editor. Here you’ll find a collection of example scripts that you can modify and try on your mobile device immediately. Almost every Tabris.js feature is demonstrated by one of these.

To load the playground script in your Developer App, go to the “URL” tab on the home screen and scan the QR code on the playground page. When you edit the code in the playground you only need to reload via the developer console or scan the QR code again.

You can also add your own scripts to the list by pressing “save”. Note that these are stored only on your machine and will be lost if you clear your browser user data. The snippets are also available in the tabris git repository.

Code Sideloading

Just like the playground scripts, you can also load an entire app that you’re developing on your machine. For this to work, your mobile device must be connected to the same network as your development machine.

After setting up your Tabris.js project, you can use the Tabris CLI to serve your app. In your project directory, call:

tabris serve

The CLI will start an HTTP server and print an URL and QR code. In the Developer App, go to the “URL” tab on the home screen and either scan the QR or enter the URL and tap “Connect”. Keep the CLI running as long as you are testing the application.


:point_right: You may notice a some delay while the Developer App downloads the sources to the mobile device. Once you’ve built the app, this delay will be gone, because the sources are then bundled with the app.
