Dojo.js SDK Setup

When to Use

Use this skill when:

• Setting up dojo.js in a new frontend project
• Configuring the SDK with world address and Torii URL
• Setting up the React provider hierarchy
• Generating TypeScript types from ABIs

SDK Initialization

import { init } from "@dojoengine/sdk";
import { DojoConfig } from "@dojoengine/core";
import { schema } from "./models.gen"; // Generated from ABI

const sdk = await init<typeof schema>({
    client: {
        worldAddress: "0x...",
        toriiUrl: "http://localhost:8080",
    },
    domain: {
        name: "MyGame",
        version: "1.0.0",
        chainId: "SN_MAIN", // or "SN_SEPOLIA"
    },
});

React Provider Setup

Note:

masterAddress

and

masterPrivateKey

are for local development only. In production, use wallet connections instead.

import { DojoSdkProvider } from "@dojoengine/sdk/react";
import { DojoConfig, DojoProvider } from "@dojoengine/core";

const dojoConfig: DojoConfig = {
    manifest: manifest, // From manifest.json
    rpcUrl: process.env.VITE_RPC_URL || "http://localhost:5050",
    toriiUrl: process.env.VITE_TORII_URL || "http://localhost:8080",
    // For local development only - never hardcode in production
    masterAddress: process.env.VITE_MASTER_ADDRESS || "0x...",
    masterPrivateKey: process.env.VITE_MASTER_PRIVATE_KEY || "",
};

function App() {
    return (
        <DojoSdkProvider
            dojoConfig={dojoConfig}
            sdk={sdk}
            // clientFn is a user-provided factory to create your game client
            clientFn={(provider) => new GameClient(provider)}
        >
            {children}
        </DojoSdkProvider>
    );
}

Environment Variables

VITE_WORLD_ADDRESS=0x...
VITE_TORII_URL=http://localhost:8080
VITE_RPC_URL=http://localhost:5050
VITE_CHAIN_ID=SN_SEPOLIA

Key Configuration Options

worldAddress

toriiUrl

http://localhost:8080

rpcUrl

chainId

SN_MAIN

SN_SEPOLIA

manifest

Using DojoContext

import { useDojoSDK } from "@dojoengine/sdk/react";

function GameComponent() {
    const { sdk, config, provider, useDojoStore } = useDojoSDK();
    // sdk: SDK instance for queries/subscriptions
    // config: DojoConfig
    // provider: DojoProvider for contract calls
    // useDojoStore: Zustand store hook
}

Common Pitfalls

1. Missing schema types: Generate types from ABI using

   @dojoengine/core

   CLI
2. CORS issues: Ensure Torii is configured to allow your frontend origin
3. Wrong chain ID: Must match the deployed world's chain
4. Provider hierarchy:

   DojoSdkProvider

   must wrap all Dojo-consuming components
