This helps keep your application secure, as errors can sometimes expose sensitive information. + +## Schema Validation + +If passing data to an actor from the frontend, use a library like [Zod](https://zod.dev/) to validate input data. + +For example, to validate action parameters: + +```typescript actor.ts +import { actor, UserError } from "rivetkit"; +import { z } from "zod"; + +// Define schema for action parameters +const IncrementSchema = z.object({ + count: z.number().int().positive() +}); + +const counter = actor({ + state: { count: 0 }, + actions: { + increment: (c, params: unknown) => { + // Validate parameters + const result = IncrementSchema.safeParse(params); + if (!result.success) { + throw new UserError("Invalid parameters", { + code: "invalid_params", + metadata: { errors: result.error.issues } + }); + } + c.state.count += result.data.count; + return c.state.count; + } + } +}); +``` + +## Streaming Data + +Actions have a single return value. To stream realtime data in response to an action, use [events](/docs/actors/events). + +## Canceling Long-Running Actions + +For operations that should be cancelable on-demand, create your own `AbortController` and chain it with `c.abortSignal` for automatic cleanup on actor shutdown. + +```typescript +import { actor } from "rivetkit"; + +const chatActor = actor({ + createVars: () => ({ controller: null as AbortController | null }), + + actions: { + generate: async (c, prompt: string) => { + const controller = new AbortController(); + c.vars.controller = controller; + c.abortSignal.addEventListener("abort", () => controller.abort()); + + const response = await fetch("https://api.example.com/generate", { + method: "POST", + body: JSON.stringify({ prompt }), + signal: controller.signal + }); + + return await response.json(); + }, + + cancel: (c) => { + c.vars.controller?.abort(); + } + } +}); +``` + +See [Actor Shutdown Abort Signal](/docs/actors/lifecycle#actor-shutdown-abort-signal) for automatically canceling operations when the actor stops. + +## Using `ActionContext` Externally + +When writing complex logic for actions, you may want to extract parts of your implementation into separate helper functions.

No shared state means no conflicts and no locks, so actors run concurrently without coordination. +- **Actor-to-actor communication:** Actors interact through [actions](/docs/actors/actions) and [events](/docs/actors/events), so they don't need to coordinate access to shared data.

Each actor represents a single user, document, chat room, or other distinct object.

If a user provides a value containing the delimiter (`:` in this example), it can break your key structure and cause key injection attacks. + +### Omitting Keys + +You can create actors without specifying a key in situations where there is a singleton actor (i.e. only one actor of a given type).

See [scaling documentation](/docs/actors/scaling) for more information. + +### Key Uniqueness + +Keys are unique within each actor name. Different actor types can use the same key: + +```typescript +import { actor, setup } from "rivetkit"; +import { createClient } from "rivetkit/client"; + +const chatRoom = actor({ state: { messages: [] as string[] }, actions: {} }); +const userProfile = actor({ state: { name: "" }, actions: {} }); + +const registry = setup({ use: { chatRoom, userProfile } }); +const client = createClient(); + +// These are different actors, same key is fine +const userChat = client.chatRoom.getOrCreate(["user-123"]); +const userProfileHandle = client.userProfile.getOrCreate(["user-123"]); +``` + +## Accessing Keys in Metadata + +Access the actor's key within the actor using the [metadata](/docs/actors/metadata) API: + +```typescript {{"title":"registry.ts"}} +import { actor, setup } from "rivetkit"; + +const chatRoom = actor({ + state: { messages: [] as string[] }, + actions: { + getRoomName: (c) => { + // Access the key from metadata + const key = c.key; + return key[1]; // Get "general" from ["room", "general"] + } + } +});

The actor is prevented from sleeping while the promise passed to `runInBackground` is still active. This is useful for fire-and-forget operations where you don't need to wait for completion. + +Common use cases: +- **Analytics and logging**: Send events to external services without delaying responses +- **State sync**: Populate external databases or APIs with updates to actor state in the background + +```typescript +import { actor } from "rivetkit"; + +interface PlayerInfo { + joinedAt: number; +} + +const gameRoom = actor({ + state: { + players: {} as Record, + scores: {} as Record + }, + + actions: { + playerJoined: (c, playerId: string) => { + c.state.players[playerId] = { joinedAt: Date.now() }; + + // Send analytics event without blocking using waitUntil + c.waitUntil( + fetch('https://analytics.example.com/events', { + method: 'POST', + body: JSON.stringify({ + event: 'player_joined', + playerId, + timestamp: Date.now() + }) + }).then(() => console.log('Analytics sent')) + ); + + return { success: true }; + }, + } +}); +``` + +### Actor Shutdown Abort Signal + +The `c.abortSignal` provides an `AbortSignal` that fires when the actor is stopping. Use this to cancel ongoing operations when the actor sleeps or is destroyed. + +```typescript +import { actor } from "rivetkit"; + +const chatActor = actor({ + actions: { + generate: async (c, prompt: string) => { + const response = await fetch("https://api.example.com/generate", { + method: "POST", + body: JSON.stringify({ prompt }), + signal: c.abortSignal + }); + + return await response.json(); + } + } +}); +``` + +See [Canceling Long-Running Actions](/docs/actors/actions#canceling-long-running-actions) for manually canceling operations on-demand. + +### Using `ActorContext` Type Externally + +When extracting logic from lifecycle hooks or actions into external functions, you'll often need to define the type of the context parameter.

This is because WebSocket connections can remain open for extended periods, and state changes made during event handlers (like `message` events) won't be automatically saved until the connection closes. + +In other cases where you need to force a state change mid-action, you can use `c.saveState()`.

+ + // Verify the scheduled task executed + expect(await schedulerHandle.getCompletedTasks()).toContain("reminder"); +}); +``` + +The `setupTest` function automatically calls `vi.useFakeTimers()`, allowing you to control time in your tests with functions like `vi.advanceTimersByTimeAsync()`.

See [connections](/docs/actors/connections) for more details. + +### Accessing the Request + +The underlying HTTP request is available via `c.request`. This is useful for accessing the path or query parameters. + +```typescript +import { actor } from "rivetkit"; + +const myActor = actor({ + state: {}, + onWebSocket: (c, websocket) => { + if (c.request) { + const url = new URL(c.request.url);
