Unable to publish when setting endpoint url to CloudFront

[miickel]

• Version: 19.49.0

• electron-updater version: 2.17.6

We have this app that we're about to distribute globally using S3 + CloudFront.

S3 is setup correctly and I can publish as usual using build --mac --win -p always, but if I set the publish.endpoint option to the CloudFront URL (e.g. https://d3tpy77yecs5fp.cloudfront.net) it fails with:

Error: Cannot Cleanup [...] XMLParserError: Unexpected close tag

Is S3 + CloudFront supported? Do I need to use setFeedURL?

Thanks

Could you please provide full error? Is publish successful?

Cloudfront won't take S3 upload requests, so you can not point endpoint to cloudfront.

However, it'd be really great to allow specify the front-end url for distribution. I know GenericServerOptions has an option for this.

@bithavoc You can set 2 publish providers, first one will be used for electron-updater, all will be used to publish (so, as you said, just use GenericServerOptions for CouldFront).

Did anyone get this working? What I am really looking for is:

1. Upload to S3
2. But download from CloudFront via autoupdate.

Is it enough to set up GenericServer (CloudFront) as first on the list, and S3 as second? Then publish will upload to S3 all files, but use CF to fetch the files?

You can set the publish config as S3 in package.json but then in your Electron script overwrite the config with a generic one for your cloudfront:

autoUpdater.setFeedURL({
    provider: 'generic',
    url: 'https://anydomain.com/',
})
autoUpdater.checkForUpdatesAndNotify()

I was investigating a similar case.
The solution is similar, but in my case I also had to specify a "channel".
This is because we used the development build tag name X.Y.Z-dev.
In this case, the uploaded feed check yml file will be generated in dev.yml.
For production builds, the tag will be X.Y.Z, so channel will be latest.

    publish:
      - provider: s3
        region: [s3 Region]
        bucket: [s3 bucket]
        path: [s3 upload prefix]
        acl: private

        autoUpdater.setFeedURL ({
          provider: "generic",
          url: "https://[CDNDomain]/[s3 upload prefix]/",
          channel: "dev",
        });
