Build

You can generate binaries from Electron using the electron-packagerpackage.

Mac

npx electron-packager ./ --platform=darwin --arch=x64 --icon=s3.icns --overwrite --protocol=sage3 --protocol-name="SAGE3 application"

Windows

npx electron-packager . --platform=win32 --arch=x64 --icon=s3.ico --overwrite

Sign

To distribute binaries, they should be notarized and signed so they can be installed smoothly on users' machines. We provide a series of build_* scripts, that you can use starting points. You will need a developer certificate for the operating system you want to target (macOS developer certificate, Windows developer certificate, ...).

Mac

Using a combination of electron-packager, electron-notarize, electron-osx-sign and electron-installer-dmg we can build installable binaries (DMG file containing a signed binary application). This is currently automated using GitHub actions on github.com.

We use the update-electron-app package to trigger an update check, download and restart. Internally, that uses the 'autoUpdater' API from Electron to check for an update.

Win

Packages used: electron-packager, electron-winstaller

TODO: signed binary steps (need help)

Deploy

We trigger a new version of the binaries but committing sources in webstack/clients/electron

• Automatic updates (macOS only for now) are handled by creating a git tag in the dev branch.
• Edit the package.json to increase the version number
• git tag 1.0.10
• git push origin 1.0.10
• Find the new update in the github release page: https://github.com/SAGE-3/next/releases
