Building the application
To build the complete application, you will need to build the python executable and the Electron portion separately.
You will not be able to do cross compatible builds for MacOS, Linux and Windows. The Python executable will be OS specific so you will need to build on each target OS separately.
For macOS you will need an Apple Developer Certificate. You can get one of these here.
Create Python executable
To first build the Python exectuable run:
yarn python:build
This should create a single file named api or (api.exe on Windows) in the pyflaskdist directory. We use pyinstaller since we can't guarantee that a user will have python on their system. Using Pyinstaller allows us to have a portable python environment alongside our flask application. When you bundle the Electron application (in the next step), the python application will be automatically included in the Electron bundle.
Create Electron application
Local build
To now build the final electron application you can use the following command:
yarn electron:build
This will create the installer needed to share your application. The final installer will be saved in the dist_electron folder.
Build and release to Github
You can also push your build to a draft release on GitHub. You will need to have a Github token in your environment to push items to github. Create your github token here. You will need the repo permissions on your token. Follow the electron-builder instructions on setting up your token.
yarn electron:build-release
