Electron Updates

This a minimal Sinatra app meant to handle the autoupdates for Electron Apps.

Running locally

1. bundle install
2. bundle exec rackup config.ru --port 3000

In development you will use the db/releases.json file.

In production you need to set the RELEASES_FILE env var to a remote file (or local also).

Configuring your client

Once you've deployed your sever, you need to configure a client to query it for updates.

The example server compares a version query parameter to determine whether an update is required.

The update resource is /updates/latest, configure your client SQRLUpdater.updateRequest:

NSURLComponents *components = [[NSURLComponents alloc] init];

components.scheme = @"http";

BOOL useLocalServer = NO;
if (useLocalServer) {
  components.host = @"localhost";
  components.port = @(3000);
} else {
  components.host = @"my-server.example.com";
}

components.path = @"/updates/latest";

NSString *bundleVersion = NSBundle.mainBundle.sqrl_bundleVersion;
components.query = [[NSString stringWithFormat:@"version=%@", bundleVersion] stringByAddingPercentEncodingWithAllowedCharacters:NSCharacterSet.URLQueryAllowedCharacterSet]

self.updater = [[SQRLUpdater alloc] initWithUpdateRequest:components.URL];

Updating releases.json

When you have updated the releases.json file, you need to call /updates/reload in order to reload the file with the new changes.
