+# Use with other libraries
+
+You can technically use RTK Query Loader with most other similar query-fetching libraries. This is possible through the use of resolvers.
+
+## Tanstack Query
+
+Below is an example of a resolver for `@tanstack/react-query`:
+
+```typescript
+import {
+  useQuery,
+  UseQueryResult as TanstackUseQueryResult,
+  UseQueryOptions,
+} from "@tanstack/react-query";
+
+const tanstackResolver = <T extends unknown>(
+  query: TanstackUseQueryResult<T>
+): UseQueryResult<T> & {
+  orignal_query: TanstackUseQueryResult<T>;
+} => ({
+  isLoading: query.isLoading,
+  isFetching: query.isFetching,
+  isSuccess: query.isSuccess,
+  isError: query.isError,
+  error: query.error,
+  data: query.data,
+  isUninitialized: !query.isFetchedAfterMount,
+  originalArgs: null,
+  refetch: () => query.refetch(),
+  currentData: query.data,
+  endpointName: undefined,
+  original_query: query,
+});
+
+const useTanstackQuery = <T extends unknown>(
+  args: UseQueryOptions<T>
+) => tanstackResolver(useQuery(args));
+```
+
+This is how you would use it:
+
+```typescript
+import { useTanstackQuery } from "../loader-resolvers";
+
+const loader = createLoader({
+  useQueries: () => {
+    const repoData = useTanstackQuery({
+      queryKey: ["repoData"],
+      queryFn: () =>
+        fetch(
+          "https://api.github.com/repos/ryfylke-react-as/rtk-query-loader"
+        ).then((res) => res.json() as Promise<RepoDataResponse>),
+    });
+
+    return {
+      queries: {
+        repoData,
+      },
+    };
+  },
+});
+```
+
+The output format will obviously be a bit different, but in this example you have access to the original query at the `.original_query` property.
+
+## More libraries
+
+If you are interested in creating resolvers for other libraries, you can [edit this page](https://github.com/ryfylke-react-as/rtk-query-loader/tree/main/docs/docs/Advanced/other-libs.md) and then [submit a pull request](https://github.com/ryfylke-react-as/rtk-query-loader/compare) on GitHub to share your resolver here.
