how to create delta file

Hi: after uploading the first version of my app,how can I build the second version to support auto-update? it seems that auto-update need a foo-version-delta.nupkg file right?I found an option win.remoteReleases in electron-builder which requires a URL to your exists updates.I’m not sure what this exactly means.For example,I created a version 0.0.1 and upload assests foo-0.0.1-full.nupkg and foo setup.exe, and then I do some changes for my app and want to build the version 0.0.2,but I don’t how to build the delta file

Hi @ArekSredzki i prefer to reopen the issue, the real problem is not on downloading the -full.nupkg file downloading while updating the app… It is for generating the -delta.nupkg file for the next update release, which the [https://github.com/electron/windows-installer](Electron windows installer) gets as an output and downloads the full.nupkg file to generate the -delta.nupkg file. The real problem here is to keep we can’t generate the -delta.nupkg file with the electron-release-server.

@ArekSredzki I agree with @SamvelRaja here. I’ve tried config like:

...
"electronWinstallerConfig": {
        "remoteReleases": "http://my.release-server.domain/update/win64"
},
...

And get an error like

Failed to sync URL as GitHub repo: Repo URL must be to the root URL of the repo e.g. https://github.com/myuser/myrepo.

It seems winstaller suffixes the remoteRelease url with RELEASES, but the URLS returned in the downloaded RELEASES file (auto generated by electron-release-server) are not useable by winstaller.

Does electron-release-server support delta builds as well as delta updates? If so what URL should we use?
