Question 1

How do I set up HTTP caching with Cashew in an Angular app?

Accepted Answer

Install the package, add `provideHttpCache` and `withHttpCacheInterceptor` to your app providers, and use the `withCache` function in HttpClient requests—the README shows a basic example with `getUsers` that caches responses automatically.

Question 2

What's the difference between Cashew and using RxJS shareReplay for caching?

Accepted Answer

Cashew provides a structured API with features like TTL, multiple storage backends, and cache buckets, while RxJS shareReplay is lower-level and requires manual setup for persistence, invalidation, and integration with Angular's HttpClient.

Question 3

How can I invalidate cache for a group of related requests in Cashew?

Accepted Answer

Use CacheBuckets: create a CacheBucket instance, assign it to requests via `withCache`, and call `CacheManager.delete(bucket)` to clear all entries in that bucket, useful for managing collections like user lists.

Question 4

Does Cashew work with service workers for offline caching?

Accepted Answer

No, Cashew is a client-side library that caches HTTP responses via Angular's HttpClient and browser storage. For offline caching, you'd need to integrate service workers separately, as it doesn't handle network-level caching.

Question 5

How to handle cache versioning when my API changes?

Accepted Answer

When using localStorage or sessionStorage, add a `version` key in `withCache`. Updating the version automatically deletes old cache entries, preventing stale data from breaking changes—the README recommends this for updates.

Question 6

Can I use Cashew with Angular standalone components?

Accepted Answer

Yes, Cashew is compatible with Angular's standalone API. The README examples use `bootstrapApplication` with providers, which is the standard approach for standalone components and interceptors.
