This is almost really simple. I used electron/update-electron-app for it, the instructions for which are:
\npackages.json with npm i update-electron-app\n\"repository\" field in that file points to your GitHub repositoryrequire('update-electron-app')() somewhere in your main.js\nI added this... and it didn't work (#106).
\nThen I spotted this recipe in the manual setup instructions for the update.electronjs.org server that it uses:
const server = 'https://update.electronjs.org'\nconst feed = `${server}/OWNER/REPO/${process.platform}-${process.arch}/${app.getVersion()}`I ran that in the Electron debugger, swapping in simonw/datasette-app as the OWNER/REPO and got this URL:
https://update.electronjs.org/simonw/datasette-app/darwin-x64/0.2.0
Which returned this:
\n\n\n\n
No updates found (needs asset matching *{mac,darwin,osx}*.zip in public repository)
It turns out your asset filename needs to match that pattern!
\nI renamed the asset I was attaching to the release to Datasette-mac.app.zip and the auto-update mechanism started working instantly.
That update URL is interesting. If you hit it with the most recent version of the software (0.2.1 at time of writing) you get this:
~ % curl -i 'https://update.electronjs.org/simonw/datasette-app/darwin-x64/0.2.1'\nHTTP/1.1 204 No Content\nServer: Cowboy\nContent-Length: 0\nConnection: keep-alive\nDate: Tue, 14 Sep 2021 03:54:47 GMT\nVia: 1.1 vegur\nBut if you tell it you are running a previous version you get this instead:
\n~ % curl -i 'https://update.electronjs.org/simonw/datasette-app/darwin-x64/0.2.0'\nHTTP/1.1 200 OK\nServer: Cowboy\nConnection: keep-alive\nContent-Type: application/json\nDate: Tue, 14 Sep 2021 03:55:19 GMT\nContent-Length: 740\nVia: 1.1 vegur\n\n{\"name\":\"0.2.1\",\"notes\":\"- Fixed bug where application would not start without a working internet connection.
