SWR data fetching patterns — keys and fetchers, isLoading vs isValidating, revalidation strategy, useSWRMutation, useSWRInfinite, conditional fetching.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# SWR Patterns

> **Quick Guide:** SWR renders the cached value immediately and revalidates behind it, so the cache
> key is the whole identity of a request and an unstable key is the single most expensive mistake
> here. `isLoading` covers the first fetch only and `isValidating` covers every fetch, which is why
> using the second as a spinner hides the data SWR exists to show. Reads are `useSWR`, writes are
> `useSWRMutation`, and a `null` key is how a request is skipped without breaking the rules of hooks.

**Detailed Resources:**

- [examples/core.md](examples/core.md) — fetchers, key shapes, state handling, `SWRConfig`
- [examples/mutations.md](examples/mutations.md) — `useSWRMutation`, optimistic updates, `populateCache`, global `mutate`
- [examples/caching.md](examples/caching.md) — revalidation strategies, prefetching, cache persistence
- [examples/pagination.md](examples/pagination.md) — `useSWRInfinite`, infinite scroll, offset and filtered paging
- [examples/conditional.md](examples/conditional.md) — the null key, dependent queries, function keys
- [examples/error-handling.md](examples/error-handling.md) — retry policy, status-specific handling, offline

How to install

The exact contents, by fingerprint
mdr add agents-inc/skills/web-data-fetching-swr@sha256:008488714cfc60cf

The line at the top of this page pins the label git:20260906.c4a7735, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
