Each application with all its resources needs to be placed into a separate directory with index.html file and app.yaml file formatted as in this example:
name: 'My Application'
Initial loading of applications to the device
Applications can be loaded from the following sources:
- a flash drive,
- over SSH,
- from a cloud storage (coming soon).
LOADING FROM A FLASH DRIVE
Copy the directory with your application into the root directory of a flash drive and insert it into the device. In several seconds the Settings page will open. You can now go to the USB drive page and see your application in the list, along with the install button. After the application is installed, it will appear on the Installed Applications page, from where it can be started.
LOADING OVER SFTP AND SSH
You can use secure shell access to upload applications (see How-To). To install an application this way, copy it into /home/pi/.inox/apps/ location, after which execute the following:
$ sudo systemctl restart adminprocess
Your application will appear on the Installed Applications page, from where it can be started.
Because Pyxis applications are web pages, most of the debugging can be done locally on a developer workstation using the standard tools available for web development. You can test your applications in Chrome browser and expect the exact same behavior on the target hardware.
Chrome DevTools allow you to create an emulated device with a specific screen size, which is helpful for evaluation of the exact look of the application:
UPDATING APPLICATION FILES OVER SFTP
You can set up an SFTP client in the development environment of your choice to upload files directly to the device. You will need SSH access for this to work (see How-To). Application files are located at
/home/pi/.inox/apps/ on the device, and you can set your tools to map them to your local files.
REMOTE INSPECTION WITH CHROME DEVTOOLS
Once uploaded to the device, applications can be debugged remotely with Chrome DevTools. On your workstation, in a terminal, execute the following command:
$ ssh -NL 9222:localhost:9222 pi@<ADDRESS>
Then, in Chrome browser, navigate to
chrome://inspect/#devices and, if everything is right, you must see the application available for remote inspection:
