Dojo Client Integration

Connect your game client or frontend to your deployed Dojo world across multiple platforms.

When to Use This Skill

• "Set up JavaScript SDK for my Dojo game"
• "Integrate Dojo with Unity"
• "Generate TypeScript bindings"
• "Connect React app to my world"

What This Skill Does

Handles client integration for:

• JavaScript/TypeScript SDK (primary)
• Unity, Unreal, Godot, Bevy (game engines)
• Typed binding generation
• Query/subscription patterns

Supported Platforms

Platform	Language	Package
JavaScript/TypeScript	JS/TS	@dojoengine/sdk
Unity	C#	dojo.unity
Unreal Engine	C++	dojo.unreal
Godot	GDScript	dojo.godot
Bevy	Rust	dojo.bevy
C/C++	C/C++	dojo.c

JavaScript/TypeScript Integration

Quick Start

Use the quickstart wizard:

pnpx @dojoengine/create-dojo start

Manual Setup

1. Install dependencies:

# Essential packages
pnpm add @dojoengine/core @dojoengine/sdk @dojoengine/torii-client

# Controller + starknet-react (recommended)
pnpm add @cartridge/connector @cartridge/controller @starknet-react/core @starknet-react/chains starknet

# For state management
pnpm add @dojoengine/state zustand immer

# Build tools for WASM support
pnpm add -D vite-plugin-wasm vite-plugin-top-level-await

2. Create dojoConfig.ts:

import { createDojoConfig } from "@dojoengine/core";
import manifest from "../path/to/manifest_dev.json";

export const dojoConfig = createDojoConfig({ manifest });

Important: The manifest must contain a valid world ABI with at least one type: "interface" entry. If manifest.world.abi is missing or empty, starknet.js throws "Unable to determine Cairo version". This is populated automatically by sozo build — if you see this error, rebuild your contracts.

3. Generate TypeScript bindings:

DOJO_MANIFEST_PATH="../path/to/Scarb.toml" sozo build --typescript

4. Initialize the SDK:

import { init } from "@dojoengine/sdk";
import { DojoSdkProvider } from "@dojoengine/sdk/react";
import { dojoConfig } from "./dojoConfig.ts";
import { setupWorld } from "./bindings/typescript/contracts.gen.ts";
import type { SchemaType } from "./bindings/typescript/models.gen.ts";

async function main() {
    const sdk = await init<SchemaType>({
        client: {
            worldAddress: dojoConfig.manifest.world.address,
            toriiUrl: "http://localhost:8080",
            relayUrl: "/ip4/127.0.0.1/tcp/9090",
        },
        domain: {
            name: "MyDojoProject",
            version: "1.0",
            chainId: "KATANA",
            revision: "1",
        },
    });

    // Use in React
    createRoot(document.getElementById("root")!).render(
        
    );
}

Controller Integration (starknet-react)

Cartridge Controller is the recommended way to handle account management in Dojo games. It provides session-based authentication via starknet-react.

Define policies and create the connector (outside React components):

import { ControllerConnector } from "@cartridge/connector";
import { SessionPolicies } from "@cartridge/controller";

const policies: SessionPolicies = {
    contracts: {
        [ACTIONS_CONTRACT_ADDRESS]: {
            methods: [
                { name: "spawn", entrypoint: "spawn" },
                { name: "move", entrypoint: "move" },
            ],
        },
    },
};

const connector = new ControllerConnector({ policies });

Wrap your app with StarknetConfig:

import { StarknetConfig } from "@starknet-react/core";
import { sepolia, mainnet } from "@starknet-react/chains";

function StarknetProvider({ children }: { children: React.ReactNode }) {
    return (
        <StarknetConfig
            autoConnect
            chains={[mainnet, sepolia]}
            connectors={[connector]}
            provider={provider}
        >
            {children}
        </StarknetConfig>
    );
}

Connect/disconnect:

import { useConnect, useDisconnect, useAccount } from "@starknet-react/core";

function ConnectWallet() {
    const { connect, connectors } = useConnect();
    const { disconnect } = useDisconnect();
    const { address } = useAccount();

    return address ? (
        <button onClick={() => disconnect()}>Disconnect</button>
    ) : (
        <button onClick={() => connect({ connector: connectors[0] })}>
            Connect
        </button>
    );
}

The useAccount() hook used in the "Executing Systems" section below returns the Controller session account once connected.

Querying Entities

import { ToriiQueryBuilder, KeysClause, MemberClause } from "@dojoengine/sdk";

// Simple query: Find a specific player
const entities = await sdk.getEntities({
    query: new ToriiQueryBuilder().withClause(
        KeysClause(["dojo_starter-Player"], ["0xabcde..."], "FixedLen").build()
    ),
});

// Access the results
entities.items.forEach((entity) => {
    const player = entity.models.dojo_starter.Player;
    console.log(`Player: ${player?.name}, Score: ${player?.score}`);
});

Complex Queries

const entities = await sdk.getEntities({
    query: new ToriiQueryBuilder()
        .withClause(
            MemberClause("dojo_starter-Player", "score", "Gt", 0).build()
        )
        .withLimit(10)
        .withOffset(0)
        .withOrderBy([{ field: "score", direction: "Desc" }]),
});

Subscribing to Changes

const [initialEntities, subscription] = await sdk.subscribeEntityQuery({
    query: new ToriiQueryBuilder()
        .withClause(
            MemberClause("dojo_starter-Player", "score", "Gt", 100).build()
        )
        .includeHashedKeys(),
    callback: ({ data, error }) => {
        if (data) {
            data.forEach((entity) => {
                const player = entity.models.dojo_starter.Player;
                console.log(`Player ${player?.id}: ${player?.score} points`);
            });
        }
    },
});

// Cancel later
// subscription.cancel();

React Hooks

import { useEntityQuery, useModels, useModel, useEntityId } from "@dojoengine/sdk/react";

function MyComponent() {
    // Subscribe to entity changes
    useEntityQuery(
        new ToriiQueryBuilder()
            .withClause(MemberClause("dojo_starter-Item", "durability", "Eq", 2).build())
            .includeHashedKeys()
    );

    // Get all items from the store
    const items = useModels("dojo_starter-Item");

    // Get a single item by entity ID
    const entityId = useEntityId(1);
    const item = useModel(entityId, "dojo_starter-Item");

    return (
        <div>
            {Object.entries(items).map(([id, item]) => (
                <div key={id}>Item {id}: durability {item?.durability}</div>
            ))}
        </div>
    );
}

Executing Systems

import { useDojoSDK } from "@dojoengine/sdk/react";
import { useAccount } from "@starknet-react/core";

function GameActions() {
    const { client } = useDojoSDK();
    const { account } = useAccount();

    async function spawn() {
        await client.actions.spawn({ account });
    }

    async function move(direction: number) {
        await client.actions.move({ account, direction });
    }

    return (
        <div>
            <button onClick={spawn}>Spawn</button>
            <button onClick={() => move(1)}>Move Right</button>
        </div>
    );
}

Client Integration Checklist

Pre-Integration

• World deployed (dojo-deploy skill)
• Torii indexer running (dojo-indexer skill)
• World address recorded
• RPC endpoint accessible

Setup

• SDK/package installed
• Bindings generated (sozo build --typescript)
• Manifest imported
• SDK initialized
• Test queries work

Integration

• Entity reads working
• System executions working
• Subscriptions configured
• Error handling added

Troubleshooting

"Cannot connect to RPC"

• Verify RPC URL is correct
• Check Katana/Torii is running
• Verify network is reachable

"World not found"

• Check world address is correct
• Verify world is deployed
• Check RPC is pointing to correct network

"Model not found"

• Ensure model is deployed
• Check model name includes namespace (dojo_starter-Position)
• Verify entity exists with that key

Next Steps

After client integration:

1. Test end-to-end workflow
2. Implement optimistic updates
3. Add error handling
4. Connect wallet for transactions
