Support publishing to Snapcraft

• Version: 20.26.0

• Target: Snap

electron-builder has a snap target, but it seems we still need to manually upload the binary using snapcraft push dist/appname_2.16.0_amd64.snap and then snapcraft release appname 1 stable. Would be nice if electron-builder could handle the publish-step too.

Python is not a good language for CLI tools (the same as NodeJS 😉), but at least now snapcraft is available for macOS. I cannot find easily instructions how to install it on Windows without Linux subsystem.

electron-builder 21 forces you to publish to store. A new publish provider snapStore is the default value for snap and your regular publish configuration is ignored unless explicitly specified for snap (under key snap).

electron build service cannot be used to publish snap for poor Windows users, who cannot migrate to a normal OS, because I don’t want to take responsibility for credentials. Maybe later electron-builder will produce a special plugin for snapcraft, so, you will be able to use official build service from Canonical to build and publish your snap. I cannot predict when it will be implemented and will be implemented or not.

I like how snapcrat is developer friendly (shame on you, bloody Apple and not so bloody but still, MS).

snapcrat push produces correct and clear error messages, so, electron-builder is not forced to add another layer of error handling.

It will be released in 2 days.

Quoting @adam-lynch , on issue #4982, you can disable it by providing a generic provider:

You can also set snap.publish to: { provider: “generic”, url: “https://anydummyurl.com” }
