I'm using amplify appsync in my electron app and all works except for the realtime events which means my app doesn't get signalled when the data changes in the cloud.
I know this is because it's running in Node which is what amplify is looking for (JS.browserOrNode) however I don't know how to fix it. Can someone advise me how I can get the realtime updates? When I query it just gets the local data unless I Datastore.stop() and Datastore.start() but surely there's a better way?
Thank you in advance!
Thanks to the amplify team on discord for this one, in amplify-js the logic for the browser vs node check is:
const browserOrNode = () => {
const isBrowser =
typeof window !== 'undefined' && typeof window.document !== 'undefined';
const isNode =
typeof process !== 'undefined' &&
process.versions != null &&
process.versions.node != null;
return {
isBrowser,
isNode,
};
};
The Datastore logic determines whether it's going to spit that warning or start the subscriptions:
if (isNode) {
logger.warn(
'Realtime disabled when in a server-side environment'
);
} else {
//#region GraphQL Subscriptions
[
// const ctlObservable: Observable<CONTROL_MSG>
ctlSubsObservable,
// const dataObservable: Observable<[TransformerMutationType, SchemaModel, Readonly<{
// id: string;
// } & Record<string, any>>]>
dataSubsObservable,
] = this.subscriptionsProcessor.start();
}
But because Electron runs the app in a Node.js environment it's why DataStore is disabling realtime.
You can stop this by forcing isNode to be false and then realtime works with electron :)
