Rivetkit

Debugging Actors

Use the inspector HTTP API to examine running actors. These endpoints are accessible through the gateway at /gateway/{actor_id}/inspector/*. Key endpoints:

• GET /inspector/summary - full actor snapshot (state, connections, RPCs, queue)
• GET /inspector/state / PATCH /inspector/state - read/write actor state
• GET /inspector/connections - active connections
• GET /inspector/rpcs - available actions
• POST /inspector/action/{name} - execute an action with {"args": [...]}
• GET /inspector/queue?limit=50 - queue status
• GET /inspector/traces?startMs=0&endMs=...&limit=1000 - trace spans (OTLP JSON)
• GET /inspector/workflow-history - workflow history and status

In local dev, no auth token is needed. In production, pass Authorization: Bearer <RIVET_INSPECTOR_TOKEN>. See the debugging docs for details.

Citing Sources

When providing information from Rivet documentation, cite the canonical URL so users can learn more. Each reference file includes its canonical URL in the header metadata.

How to cite:

• Use inline links for key concepts: "Use actor keys to uniquely identify instances."
• Add a "Learn more" link after explanations for complex topics

Finding canonical URLs:

The Reference Map below links to reference files. Each file's header contains:

> Canonical URL: https://rivet.dev/docs/actors/actions

Use that canonical URL when citing, not the reference file path.

Examples:

• Actions → https://rivet.dev/docs/actors/actions
• React client → https://rivet.dev/docs/clients/react
• Self-hosting on Kubernetes → https://rivet.dev/docs/self-hosting/kubernetes

First Steps

1. Install RivetKit (latest: 2.1.0-rc.2)

   npm install [email protected]
   

2. Define a registry with setup({ use: { /* actors */ } }).
3. Expose registry.serve() or registry.handler() (serverless) or registry.startRunner() (runner mode). Prefer serverless mode unless the user has a specific reason to use runner mode.
4. Verify /api/rivet/metadata returns 200 before deploying.
5. Configure Rivet Cloud or self-hosted engine
6. Integrate clients (see client guides below for JavaScript, React, or Swift)
7. Prompt the user if they want to deploy. If so, go to Deploying Rivet Backends.

For more information, read the quickstart guide relevant to the user's project.

Error Handling Policy

• Prefer fail-fast behavior by default.
• Avoid try/catch unless it is required for a real recovery path, cleanup boundary, or to add actionable context.
• Never swallow errors. If you add a catch, you must handle the error explicitly, at minimum by logging it.
• When you cannot recover, log context and rethrow.

State vs Vars: Persistence Rules

c.vars is ephemeral. Data in c.vars is lost on every restart, crash, upgrade, or sleep/wake cycle. Only use c.vars for non-serializable objects (e.g., physics engines, WebSocket references, event emitters, caches) or truly transient runtime data (e.g., current input direction that doesn't matter after disconnect).

Persistent storage options. Any data that must survive restarts belongs in one of these, NOT in c.vars:

• c.state — CBOR-serializable data for small, bounded datasets. Ideal for configuration, counters, small player lists, phase flags, etc. Keep under 128 KB. Do not store unbounded or growing data here (e.g., chat logs, event histories, spawned entity lists that grow without limit). State is read/written as a single blob on every persistence cycle.
• c.kv — Key-value store for unbounded data. This is what c.state uses under the hood. Supports binary values. Use for larger or variable-size data like user inventories, world chunks, file blobs, or any collection that may grow over time. Keys are scoped to the actor instance.
• c.db — SQLite database for structured or complex data. Use when you need queries, indexes, joins, aggregations, or relational modeling. Ideal for leaderboards, match histories, player pools, or any data that benefits from SQL.

Common mistake: Storing meaningful game/application data in c.vars instead of persisting it. For example, if users can spawn objects in a physics simulation, the spawn definitions (position, size, type) must be persisted in c.state (or c.kv if unbounded), even though the physics engine handles (non-serializable) live in c.vars. On restart, run() should recreate the runtime objects from the persisted data.

Deploying Rivet Backends

Assume the user is deploying to Rivet Cloud, unless otherwise specified. If user is self-hosting, read the self-hosting guides below.

1. Verify that Rivet Actors are working in local dev
2. Prompt the user to choose a provider to deploy to (see Connect for a list of providers, such as Vercel, Railway, etc)
3. Follow the deploy guide for that given provider. You will need to instruct the user when you need manual intervention.

API Reference

The RivetKit OpenAPI specification is available in the skill directory at openapi.json. This file documents all HTTP endpoints for managing actors.

Misc Notes

• The Rivet domain is rivet.dev, not rivet.gg

Features

• Long-Lived, Stateful Compute: Each unit of compute is like a tiny server that remembers things between requests – no need to re-fetch data from a database or worry about timeouts. Like AWS Lambda, but with memory and no timeouts.
• Blazing-Fast Reads & Writes: State is stored on the same machine as your compute, so reads and writes are ultra-fast. No database round trips, no latency spikes. State is persisted to Rivet for long term storage, so it survives server restarts.
• Realtime: Update state and broadcast changes in realtime with WebSockets. No external pub/sub systems, no polling – just built-in low-latency events.
• Infinitely Scalable: Automatically scale from zero to millions of concurrent actors. Pay only for what you use with instant scaling and no cold starts.
• Fault Tolerant: Built-in error handling and recovery. Actors automatically restart on failure while preserving state integrity and continuing operations.

When to Use Rivet Actors

• AI agents & sandboxes: multi-step toolchains, conversation memory, sandbox orchestration.
• Multiplayer or collaborative apps: CRDT docs, shared cursors, realtime dashboards, chat.
• Workflow automation: background jobs, cron, rate limiters, durable queues, backpressure control.
• Data-intensive backends: geo-distributed or per-tenant databases, in-memory caches, sharded SQL.
• Networking workloads: WebSocket servers, custom protocols, local-first sync, edge fanout.

Actor Quick Reference

In-Memory State

Persistent data that survives restarts, crashes, and deployments. State is persisted on Rivet Cloud or Rivet self-hosted, so it survives restarts if the current process crashes or exits.

Static Initial State

import { actor } from "rivetkit";

const counter = actor({
  state: { count: 0 },
  actions: {
    increment: (c) => c.state.count += 1,
  },
});

Dynamic Initial State

import { actor } from "rivetkit";

interface CounterState {
  count: number;
}

const counter = actor({
  state: { count: 0 } as CounterState,
  createState: (c, input: { start?: number }): CounterState => ({
    count: input.start ?? 0,
  }),
  actions: {
    increment: (c) => c.state.count += 1,
  },
});

Documentation

Keys

Keys uniquely identify actor instances. Use compound keys (arrays) for hierarchical addressing:

import { actor, setup } from "rivetkit";
import { createClient } from "rivetkit/client";

const chatRoom = actor({
  state: { messages: [] as string[] },
  actions: {
    getRoomInfo: (c) => ({ org: c.key[0], room: c.key[1] }),
  },
});

const registry = setup({ use: { chatRoom } });
const client = createClient<typeof registry>();

// Compound key: [org, room]
client.chatRoom.getOrCreate(["org-acme", "general"]);

// Access key inside actor via c.key

Don't build keys with string interpolation like "org:${userId}" when userId contains user data. Use arrays instead to prevent key injection attacks.

Documentation

Input

Pass initialization data when creating actors.

import { actor, setup } from "rivetkit";
import { createClient } from "rivetkit/client";

const game = actor({
  createState: (c, input: { mode: string }) => ({ mode: input.mode }),
  actions: {},
});

const registry = setup({ use: { game } });
const client = createClient<typeof registry>();

// Client usage
const gameHandle = client.game.getOrCreate(["game-1"], {
  createWithInput: { mode: "ranked" }
});

Documentation

Temporary Variables

Temporary data that doesn't survive restarts. Use for non-serializable objects (event emitters, connections, etc).

Static Initial Vars

import { actor } from "rivetkit";

const counter = actor({
  state: { count: 0 },
  vars: { lastAccess: 0 },
  actions: {
    increment: (c) => {
      c.vars.lastAccess = Date.now();
      return c.state.count += 1;
    },
  },
});

Dynamic Initial Vars

import { actor } from "rivetkit";

const counter = actor({
  state: { count: 0 },
  createVars: () => ({
    emitter: new EventTarget(),
  }),
  actions: {
    increment: (c) => {
      c.vars.emitter.dispatchEvent(new Event("change"));
      return c.state.count += 1;
    },
  },
});

Documentation

Actions

Actions are the primary way clients and other actors communicate with an actor.

import { actor } from "rivetkit";

const counter = actor({
  state: { count: 0 },
  actions: {
    increment: (c, amount: number) => (c.state.count += amount),
    getCount: (c) => c.state.count,
  },
});

Documentation

Events & Broadcasts

Events enable real-time communication from actors to connected clients.

import { actor, event } from "rivetkit";

const chatRoom = actor({
  state: { messages: [] as string[] },
  events: {
    newMessage: event<{ text: string }>(),
  },
  actions: {
    sendMessage: (c, text: string) => {
      // Broadcast to ALL connected clients
      c.broadcast("newMessage", { text });
    },
  },
});

Documentation

Connections

Access the current connection via c.conn or all connected clients via c.conns. Use c.conn.id or c.conn.state to securely identify who is calling an action. Connection state is initialized via connState or createConnState, which receives parameters passed by the client on connect.

Static Connection Initial State

import { actor } from "rivetkit";

const chatRoom = actor({
  state: {},
  connState: { visitorId: 0 },
  onConnect: (c, conn) => {
    conn.state.visitorId = Math.random();
  },
  actions: {
    whoAmI: (c) => c.conn.state.visitorId,
  },
});

Dynamic Connection Initial State

import { actor } from "rivetkit";

const chatRoom = actor({
  state: {},
  // params passed from client
  createConnState: (c, params: { userId: string }) => ({
    userId: params.userId,
  }),
  actions: {
    // Access current connection's state and params
    whoAmI: (c) => ({
      state: c.conn.state,
      params: c.conn.params,
    }),
    // Iterate all connections with c.conns
    notifyOthers: (c, text: string) => {
      for (const conn of c.conns.values()) {
        if (conn !== c.conn) conn.send("notification", { text });
      }
    },
  },
});

Documentation

Queues

Use queues to process durable messages in order inside a run loop.

import { actor, queue } from "rivetkit";

const counter = actor({
  state: { value: 0 },
  queues: {
    increment: queue<{ amount: number }>(),
  },
  run: async (c) => {
    for await (const message of c.queue.iter()) {
      c.state.value += message.body.amount;
    }
  },
});

Documentation

Workflows

Use workflows when your run logic needs durable, replayable multi-step execution.

import { actor, queue } from "rivetkit";
import { workflow } from "rivetkit/workflow";

const worker = actor({
  state: { processed: 0 },
  queues: {
    tasks: queue<{ url: string }>(),
  },
  run: workflow(async (ctx) => {
    await ctx.loop("task-loop", async (loopCtx) => {
        const message = await loopCtx.queue.next("wait-task");

        await loopCtx.step("process-task", async () => {
          await processTask(message.body.url);
          loopCtx.state.processed += 1;
        });

      });
  }),
});

async function processTask(url: string): Promise<void> {
  const res = await fetch(url, { method: "POST" });
  if (!res.ok) throw new Error(`Task failed: ${res.status}`);
}

Documentation

Actor-to-Actor Communication

Actors can call other actors using c.client().

import { actor, setup } from "rivetkit";

const inventory = actor({
  state: { stock: 100 },
  actions: {
    reserve: (c, amount: number) => { c.state.stock -= amount; }
  }
});

const order = actor({
  state: {},
  actions: {
    process: async (c) => {
      const client = c.client<typeof registry>();
      await client.inventory.getOrCreate(["main"]).reserve(1);
    },
  },
});

const registry = setup({ use: { inventory, order } });

Documentation

Scheduling

Schedule actions to run after a delay or at a specific time. Schedules persist across restarts, upgrades, and crashes.

import { actor, event } from "rivetkit";

const reminder = actor({
  state: { message: "" },
  events: {
    reminder: event<{ message: string }>(),
  },
  actions: {
    // Schedule action to run after delay (ms)
    setReminder: (c, message: string, delayMs: number) => {
      c.state.message = message;
      c.schedule.after(delayMs, "sendReminder");
    },
    // Schedule action to run at specific timestamp
    setReminderAt: (c, message: string, timestamp: number) => {
      c.state.message = message;
      c.schedule.at(timestamp, "sendReminder");
    },
    sendReminder: (c) => {
      c.broadcast("reminder", { message: c.state.message });
    },
  },
});

Documentation

Destroying Actors

Permanently delete an actor and its state using c.destroy().

import { actor } from "rivetkit";

const userAccount = actor({
  state: { email: "", name: "" },
  onDestroy: (c) => {
    console.log(`Account ${c.state.email} deleted`);
  },
  actions: {
    deleteAccount: (c) => {
      c.destroy();
    },
  },
});

Documentation

Lifecycle Hooks

Actors support hooks for initialization, background processing, connections, networking, and state changes. Use run for long-lived background loops, and exit cleanly on shutdown with c.aborted or c.abortSignal.

import { actor, event, queue } from "rivetkit";

interface RoomState {
  users: Record<string, boolean>;
  name?: string;
}

interface RoomInput {
  roomName: string;
}

interface ConnState {
  userId: string;
  joinedAt: number;
}

const chatRoom = actor({
  state: { users: {} } as RoomState,
  vars: { startTime: 0 },
  connState: { userId: "", joinedAt: 0 } as ConnState,
  events: {
    stateChanged: event<RoomState>(),
  },
  queues: {
    work: queue<{ task: string }>(),
  },

  // State & vars initialization
  createState: (c, input: RoomInput): RoomState => ({ users: {}, name: input.roomName }),
  createVars: () => ({ startTime: Date.now() }),

  // Actor lifecycle
  onCreate: (c) => console.log("created", c.key),
  onDestroy: (c) => console.log("destroyed"),
  onWake: (c) => console.log("actor started"),
  onSleep: (c) => console.log("actor sleeping"),
  run: async (c) => {
    for await (const message of c.queue.iter()) {
      console.log("processing", message.body.task);
    }
  },
  onStateChange: (c, newState) => c.broadcast("stateChanged", newState),

  // Connection lifecycle
  createConnState: (c, params): ConnState => ({ userId: (params as { userId: string }).userId, joinedAt: Date.now() }),
  onBeforeConnect: (c, params) => { /* validate auth */ },
  onConnect: (c, conn) => console.log("connected:", conn.state.userId),
  onDisconnect: (c, conn) => console.log("disconnected:", conn.state.userId),

  // Networking
  onRequest: (c, req) => new Response(JSON.stringify(c.state)),
  onWebSocket: (c, socket) => socket.addEventListener("message", console.log),

  // Response transformation
  onBeforeActionResponse: <Out>(c: unknown, name: string, args: unknown[], output: Out): Out => output,

  actions: {},
});

Documentation

Context Types

When writing helper functions outside the actor definition, use *ContextOf<typeof myActor> to extract the correct context type. Do not manually define your own context interface — always derive it from the actor definition.

import { actor, ActionContextOf } from "rivetkit";

const gameRoom = actor({
  state: { players: [] as string[], score: 0 },
  actions: {
    addPlayer: (c, playerId: string) => {
      validatePlayer(c, playerId);
      c.state.players.push(playerId);
    },
  },
});

// Good: derive context type from actor definition
function validatePlayer(c: ActionContextOf<typeof gameRoom>, playerId: string) {
  if (c.state.players.includes(playerId)) {
    throw new Error("Player already in room");
  }
}

// Bad: don't manually define context types like this
// type MyContext = { state: { players: string[] }; ... };

Documentation

Errors

Use UserError to throw errors that are safely returned to clients. Pass metadata to include structured data. Other errors are converted to generic "internal error" for security.

Actor

import { actor, UserError } from "rivetkit";

const user = actor({
  state: { username: "" },
  actions: {
    updateUsername: (c, username: string) => {
      if (username.length < 3) {
        throw new UserError("Username too short", {
          code: "username_too_short",
          metadata: { minLength: 3, actual: username.length },
        });
      }
      c.state.username = username;
    },
  },
});

Client

import { actor, setup } from "rivetkit";
import { createClient, ActorError } from "rivetkit/client";

const user = actor({
  state: { username: "" },
  actions: { updateUsername: (c, username: string) => { c.state.username = username; } }
});

const registry = setup({ use: { user } });
const client = createClient<typeof registry>();

try {
  await client.user.getOrCreate([]).updateUsername("ab");
} catch (error) {
  if (error instanceof ActorError) {
    console.log(error.code);     // "username_too_short"
    console.log(error.metadata); // { minLength: 3, actual: 2 }
  }
}

Documentation

Low-Level HTTP & WebSocket Handlers

For custom protocols or integrating libraries that need direct access to HTTP Request/Response or WebSocket connections, use onRequest and onWebSocket.

HTTP Handler Documentation · WebSocket Handler Documentation

Icons & Names

Customize how actors appear in the UI with display names and icons. It's recommended to always provide a name and icon to actors in order to make them easier to distinguish in the dashboard.

import { actor } from "rivetkit";

const chatRoom = actor({
  options: {
    name: "Chat Room",
    icon: "💬",  // or FontAwesome: "comments", "chart-line", etc.
  },
  // ...
});

Common Patterns

Actors scale naturally through isolated state and message-passing. Structure your applications with these patterns:

Documentation

Actor Per Entity

Create one actor per user, document, or room. Use compound keys to scope entities:

import { createClient } from "rivetkit/client";
import type { registry } from "./actors";

const client = createClient<typeof registry>();

// Single key: one actor per user
client.user.getOrCreate(["user-123"]);

// Compound key: document scoped to an organization
client.document.getOrCreate(["org-acme", "doc-456"]);

import { actor, setup } from "rivetkit";

export const user = actor({
  state: { name: "" },
  actions: {},
});

export const document = actor({
  state: { content: "" },
  actions: {},
});

export const registry = setup({ use: { user, document } });

Coordinator & Data Actors

Data actors handle core logic (chat rooms, game sessions, user data). Coordinator actors track and manage collections of data actors—think of them as an index.

import { actor, setup } from "rivetkit";

// Coordinator: tracks chat rooms within an organization
export const chatRoomList = actor({
  state: { rooms: [] as string[] },
  actions: {
    addRoom: async (c, name: string) => {
      // Create the chat room actor
      const client = c.client<typeof registry>();
      await client.chatRoom.create([c.key[0], name]);
      c.state.rooms.push(name);
    },
    listRooms: (c) => c.state.rooms,
  },
});

// Data actor: handles a single chat room
export const chatRoom = actor({
  state: { messages: [] as string[] },
  actions: {
    send: (c, msg: string) => { c.state.messages.push(msg); },
  },
});

export const registry = setup({ use: { chatRoomList, chatRoom } });

import { createClient } from "rivetkit/client";
import type { registry } from "./actors";

const client = createClient<typeof registry>();

// Coordinator per org
const coordinator = client.chatRoomList.getOrCreate(["org-acme"]);
await coordinator.addRoom("general");
await coordinator.addRoom("random");

// Access chat rooms created by coordinator
client.chatRoom.get(["org-acme", "general"]);

Run Loop

Use a run loop for continuous background work inside an actor. Process queue messages in order, run logic on intervals, stream AI responses, or coordinate long-running tasks.

import { actor, queue, setup } from "rivetkit";

const counterWorker = actor({
  state: { value: 0 },
  queues: {
    mutate: queue<{ delta: number }>(),
  },
  run: async (c) => {
    for await (const message of c.queue.iter()) {
      c.state.value += message.body.delta;
    }
  },
  actions: {
    getValue: (c) => c.state.value,
  },
});

const registry = setup({ use: { counterWorker } });

Workflow Loop

Use this pattern for long-lived, durable workflows that initialize resources, process commands in a loop, then clean up.

import { actor, queue, setup } from "rivetkit";
import { Loop, workflow } from "rivetkit/workflow";

type WorkMessage = { amount: number };
type ControlMessage = { type: "stop"; reason: string };

const worker = actor({
  state: {
    phase: "idle" as "idle" | "running" | "stopped",
    processed: 0,
    total: 0,
    stopReason: null as string | null,
  },
  queues: {
    work: queue<WorkMessage>(),
    control: queue<ControlMessage>(),
  },
  run: workflow(async (ctx) => {
    await ctx.step("setup", async () => {
      await fetch("https://api.example.com/workers/init", { method: "POST" });
      ctx.state.phase = "running";
      ctx.state.stopReason = null;
    });

    const stopReason = await ctx.loop("worker-loop", async (loopCtx) => {
        const message = await loopCtx.queue.next("wait-command", {
          names: ["work", "control"],
        });

        if (message.name === "work") {
          await loopCtx.step("apply-work", async () => {
            await fetch("https://api.example.com/workers/process", {
              method: "POST",
              body: JSON.stringify({ amount: message.body.amount }),
            });
            loopCtx.state.processed += 1;
            loopCtx.state.total += message.body.amount;
          });
          return;
        }

        return Loop.break((message.body as ControlMessage).reason);
      });

    await ctx.step("teardown", async () => {
      await fetch("https://api.example.com/workers/shutdown", { method: "POST" });
      ctx.state.phase = "stopped";
      ctx.state.stopReason = stopReason;
    });
  }),
});

const registry = setup({ use: { worker } });

Documentation

Actions vs Queues

• Actions are not durable. Use them for realtime reads, ephemeral data, and low-latency communication like player input.
• Queues are durable. Use them to serialize mutations through the run loop, avoiding race conditions with SQLite and other local state. Callers can still wait for a response from queued work.

Authentication, Security, & CORS

• Validate credentials in onBeforeConnect or createConnState and throw an error to reject unauthorized connections.
• Use c.conn.state to securely identify users in actions rather than trusting action parameters.
• For cross-origin access, validate the request origin in onBeforeConnect.

Authentication Documentation · CORS Documentation

Versions & Upgrades

When deploying new code, set a version number so Rivet can route new actors to the latest runner and optionally drain old ones. Use a build timestamp, git commit count, or CI build number as the version.

Documentation

Anti-Patterns

Never build a "god" actor

Do not put all your logic in a single actor. A god actor serializes every operation through one bottleneck, kills parallelism, and makes the entire system fail as a unit. Split into focused actors per entity.

Never create an actor per request

Actors are long-lived and maintain state across requests. Creating a new actor for every incoming request throws away the core benefit of the model and wastes resources on actor creation and teardown. Use actors for persistent entities and regular functions for stateless work.
