Configuring auto-update for an Electron app
Configuring auto-update for an Electron app#
This is almost really simple. I used electron/update-electron-app for it, the instructions for which are:
- Add it to
packages.jsonwithnpm i update-electron-app - Make sure your
"repository"field in that file points to your GitHub repository - Use GitHub releases to release signed versions of your application
- Add
require('update-electron-app')()somewhere in yourmain.js
I added this… and it didn’t work (#106).
Then I spotted this recipe in the manual setup instructions for the update.electronjs.org server that it uses:
1const server = 'https://update.electronjs.org'2const 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:
No updates found (needs asset matching *{mac,darwin,osx}*.zip in public repository)
It turns out your asset filename needs to match that pattern!
I renamed the asset I was attaching to the release to Datasette-mac.app.zip and the auto-update mechanism started working instantly.
How it works#
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:
1~ % curl -i 'https://update.electronjs.org/simonw/datasette-app/darwin-x64/0.2.1'2HTTP/1.1 204 No Content3Server: Cowboy4Content-Length: 05Connection: keep-alive6Date: Tue, 14 Sep 2021 03:54:47 GMT7Via: 1.1 vegurBut if you tell it you are running a previous version you get this instead:
1~ % curl -i 'https://update.electronjs.org/simonw/datasette-app/darwin-x64/0.2.0'2HTTP/1.1 200 OK3Server: Cowboy4Connection: keep-alive5Content-Type: application/json6Date: Tue, 14 Sep 2021 03:55:19 GMT7Content-Length: 7408Via: 1.1 vegur9
