+# SWR Integration
+
+[SWR](https://swr.vercel.app/) is a React Hooks library for data fetching that provides features like caching, revalidation, and more. oRPC SWR integration is very lightweight and straightforward. There is no extra overhead.
+
+::: warning
+This guide assumes you are already familiar with [SWR](https://swr.vercel.app/). If you need a refresher, review the official SWR documentation before continuing.
+:::
+
+## Installation
+
+::: code-group
+
+```sh [npm]
+npm install @orpc/swr@beta
+```
+
+```sh [yarn]
+yarn add @orpc/swr@beta
+```
+
+```sh [pnpm]
+pnpm add @orpc/swr@beta
+```
+
+```sh [bun]
+bun add @orpc/swr@beta
+```
+
+```sh [deno]
+deno add npm:@orpc/swr@beta
+```
+
+:::
+
+## Setup
+
+Before you begin, set up either a [server-side client](/docs/client/server-side) or a [client-side client](/docs/client/client-side).
+
+```ts
+import { createSWRUtils } from '@orpc/swr'
+
+export const orpc = createSWRUtils(client)
+
+orpc.planet.find.key({ input: { id: 123 } })
+```
+
+::: details Avoiding Key Conflicts?
+
+You can avoid key conflicts by passing a unique prefix when creating your utils:
+
+```ts
+const userORPC = createSWRUtils(userClient, {
+  prefix: 'user'
+})
+
+const postORPC = createSWRUtils(postClient, {
+  prefix: 'post'
+})
+```
+
+:::
+
+## Data Fetching
+
+Use `.key` and `.fetcher` methods to configure `useSWR` for data fetching:
+
+```ts
+import useSWR from 'swr'
+
+const { data, error, isLoading } = useSWR(
+  orpc.planet.find.key({ input: { id: 123 } }),
+  orpc.planet.find.fetcher({ context: { cache: true } }), // Provide client context if needed
+)
+```
+
+## Infinite Queries
+
+Use `.key` and `.fetcher` methods to configure `useSWRInfinite` for infinite queries:
+
+```ts
+import useSWRInfinite from 'swr/infinite'
+
+const { data, error, isLoading, size, setSize } = useSWRInfinite(
+  (index, previousPageData) => {
+    if (previousPageData && !previousPageData.nextCursor) {
+      return null // reached the end
+    }
+
+    return orpc.planet.list.key({ input: { cursor: previousPageData?.nextCursor } })
+  },
+  orpc.planet.list.fetcher({ context: { cache: true } }), // Provide client context if needed
+)
+```
+
+## Subscriptions
+
+Use `.key` and `.subscriber` methods to configure `useSWRSubscription` to subscribe to an [AsyncIteratorObject](/docs/async-iterator-object):
+
+```ts
+import useSWRSubscription from 'swr/subscription'
+
+const { data, error } = useSWRSubscription(
+  orpc.streamed.key({ input: { id: 3 } }),
+  orpc.streamed.subscriber({ context: { cache: true }, maxChunks: 10 }), // Provide client context if needed
+)
+```
+
+Use `.liveSubscriber` to subscribe to the latest events without chunking:
+
+```ts
+import useSWRSubscription from 'swr/subscription'
+
+const { data, error } = useSWRSubscription(
+  orpc.streamed.key({ input: { id: 3 } }),
+  orpc.streamed.liveSubscriber({ context: { cache: true } }), // Provide client context if needed
+)
+```
+
+## Mutations
+
+Use `.key` and `.mutator` methods to configure `useSWRMutation` for mutations with automatic revalidation on success:
+
+```ts
+import useSWRMutation from 'swr/mutation'
+
+const { trigger, isMutating } = useSWRMutation(
+  orpc.planet.list.key(),
+  orpc.planet.create.mutator({ context: { cache: true } }), // Provide client context if needed
+)
+
+trigger({ name: 'New Planet' }) // auto revalidate orpc.planet.list.key() on success
+```
+
+## Manual Revalidation
+
+Use `.matcher` to invalidate data manually:
+
+```ts
+import { mutate } from 'swr'
+
+mutate(orpc.matcher()) // invalidate all orpc data
+mutate(orpc.planet.matcher()) // invalidate all planet data
+mutate(orpc.planet.find.matcher({ input: { id: 123 }, strategy: 'exact' })) // invalidate specific planet data
+```
+
+## Calling Clients
+
+Use `.call` to call a procedure client directly. It's an alias for corresponding procedure client.
+
+```ts
+const planet = await orpc.planet.find.call({ id: 123 })
+```
+
+## Operation Context
+
+When clients are invoked through the SWR integration, an **operation context** is automatically added to the [client context](/docs/client/rpc-link#using-client-context). This context can be used to configure the request behavior, like setting the HTTP method.
+
+```ts
+import {
+  SWR_OPERATION_CONTEXT_SYMBOL,
+  SWROperationContext,
+} from '@orpc/swr'
+
+interface ClientContext extends SWROperationContext {
+}
+
+const GET_OPERATION_TYPE = new Set(['fetcher', 'subscriber', 'liveSubscriber'])
+
+const link = new RPCLink<ClientContext>({
+  method: ({ context }, path) => {
+    const operationType = context[SWR_OPERATION_CONTEXT_SYMBOL]?.type
+
+    if (operationType && GET_OPERATION_TYPE.has(operationType)) {
+      return 'GET'
+    }
+
+    return 'POST'
+  },
+})
+```
