App Debugging

You can monitor the execution information of web apps or JS services running on the target device with Web Inspector and Node Inspector. For this, you need to create a package file (.ipk) without minifying.

Web Inspector

The webOS TV platform supports Web Inspector for debugging web apps. Web Inspector monitors your app running on a target device with the execution information. Web Inspector uses the Chromium browser as a default browser.

To use the Inspector, you need to have Chromium installed, of which the version is compatible with the webOS TV version. The following table shows the compatible Chromium version by webOS TV version and their download links.
