Question 1

How do I validate data in angular-async-local-storage?

Accepted Answer

Use the get method with a JSON schema parameter, like this.storage.get('key', { type: 'string' }).subscribe(...). The library validates data against the schema and errors if invalid, with full details in the validation guide.

Question 2

angular-async-local-storage vs native localStorage: which should I use?

Accepted Answer

For Angular apps, angular-async-local-storage is better as it prevents UI freezes with async IndexedDB and integrates with RxJS. Use native localStorage only for trivial, infrequent storage where simplicity outweighs performance concerns.

Question 3

Can I use angular-async-local-storage with Angular Universal?

Accepted Answer

It's client-side storage, so on the server, it won't work. You'll need to handle server-side rendering separately, possibly by mocking or avoiding storage calls during SSR, as it relies on browser APIs.

Question 4

How to handle errors when reading data?

Accepted Answer

Subscribe with error handling or use catchError from RxJS. For example, this.storage.get('key').pipe(catchError(() => of(defaultValue))).subscribe(...). The errors guide provides specifics on potential issues.

Question 5

Does it support watching for changes in stored values?

Accepted Answer

Yes, use the watch method to get an Observable that emits when the value changes. For example, this.storage.watch('key').subscribe(value => ...). Refer to the watching guide for advanced usage.
