q-data.json: split per loader by wmertens · Pull Request #8501 · QwikDev/qwik

wmertens · 2026-03-28T14:53:14Z

Big sanity improvement, some breaking changes:
Route loaders now each get their own cacheable .json path, and SPA navigation no longer needs to contact the server on every click.

Breaking:

Routeloaders are now Async Signals, and the loader.value.failed in-band data is no longer available. Instead, read from loader.error.
Routeloaders no longer resolve action results. The reason is that routeloaders are supposed to be cacheable and having them differ based on actions is wrong.
There are several other ways to use action results, so this isn't limiting.

The net result of this change:

less server traffic
no incorrect q-data.json caches
saner API

Pull request overview

This PR refactors Qwik Router’s data fetching model by replacing monolithic q-data.json requests with per-loader cacheable JSON endpoints and aligning route loaders with the new AsyncSignal-based loader runtime. It also introduces supporting middleware/handlers, build-time route metadata emission for loader hashes, SSG output changes, and updates docs/tests accordingly.

Changes:

Replace q-data.json SPA navigation with per-loader q-loader-*.json fetching + caching/ETag support, and make route loaders AsyncSignals.
Add new request recognition + middleware handlers for loader/action JSON flows, and update SSG to emit per-loader files.
Enhance the router Vite plugin to track loader segment hashes and inject them into the generated route trie (_R), including dev HMR invalidation.

+Instead, Qwik Router now retrieves `q-loader-${hash}.${manifestHash}.json` for RouteLoader data. You can specify expiry for each RouteLoader individually, and it is automatically used to set browser caching headers. The `manifestHash` ensures that when you build a new version of your app, the old cached data will be invalidated and the new data will be fetched.
+
+The default expiry for RouteLoader data is 2 minutes, so that prefetching and caching of RouteLoader data is useful. You control this with the `expiry` option on each RouteLoader, and you can set it to `0` to disable caching.
+
+Furthermore, any RouteLoader that has `expiry: 0` will be generated as a file during SSG, which allows SPA navigation to work even without a server.
+
+Note: Be careful with caching for RouteLoaders that return user-specific data, especially regarding logout and CDN caching. Use low expiry times for these and use `eTag` to still allow caching benefits.


+FEAT: route loaders now accept `search` to only allow certain query parameters to trigger the loader. This means that random search parameters won't cause the loader to re-run. If you do not pass `search`, then all search parameters will be passed to the loader and will trigger it when they change.
+
+However, `qwikRouter` now has the option `strictLoaders` which is `true` by default, which means that if you do not specify `search` for a loader, then it will not receive any search parameters and will not re-run when the search parameters change.


+By default, after an action completes, ALL current route loaders are invalidated on the client and re-fetched as needed (so that the browser cache is correct). This can be controlled with:
+
+- `invalidate: [loader1, loader2]` — Only invalidate specific loaders. The client re-fetches them individually. Other loaders keep their current data. - `invalidate: []` — No loaders are invalidated. The action response only contains the action result. Use this when the action doesn't affect any loader data.
+


+\#\# Options
+
+- `search: string[]` — Allowlist of URL search params the loader depends on. Only listed params are sent in the request and changes to other params are ignored. `search: []` means no search params are sent and only route path changes trigger a re-fetch. - `allowStale: false` — Clears the previous value when re-fetching, so components see a loading state instead of stale data during navigation. Useful when old data would be confusing. - `eTag` — Enable ETag-based caching. Can be `true` (auto-hash), a string, or a function. - `expires` / `poll` — Control client-side caching and polling behavior.
+
+The `strictLoaders` Vite plugin option applies `search: []` globally for all loaders that don't specify an explicit `search` option.

- Each loader gets its own .json file served where it's exported - `q-data.json` no longer exists - declarative redirects are found in the routing trie on the client - programmatic redirects are passed in the JSON results - route loaders get expiry and polling - SPA navigation no longer waits for route loaders - `showStale: false` prevents showing the user stale data - `search` allows defining which search params matter for the loader

instead of sending data that the browser can't cache

- search: [] was skipping path changes - actions should set HTTP status - don't lose loadersByFile

		FEAT: route loaders now accept `search` to only allow certain query parameters to trigger the loader. This means that random search parameters won't cause the loader to re-run. If you do not pass `search`, then all search parameters will be passed to the loader and will trigger it when they change.

		However, `qwikRouter` now has the option `strictLoaders` which is `true` by default, which means that if you do not specify `search` for a loader, then it will not receive any search parameters and will not re-run when the search parameters change.

		By default, after an action completes, ALL current route loaders are invalidated on the client and re-fetched as needed (so that the browser cache is correct). This can be controlled with:

		- `invalidate: [loader1, loader2]` — Only invalidate specific loaders. The client re-fetches them individually. Other loaders keep their current data. - `invalidate: []` — No loaders are invalidated. The action response only contains the action result. Use this when the action doesn't affect any loader data.
