examples/example-vite-react-sdk/src/useDojo.tsx (1)
4-12: Good start with documentation, consider enhancing it further.The JSDoc comments provide a clear overview of the hook's purpose and behavior. To make it even more helpful for developers, consider adding:
- An
@examplesection showing typical usage- Type information for the returned
setupandaccountobjects@seereferences to related components likeDojoProviderHere's a suggested enhancement:
/** * Custom hook to access the Dojo context and account information. * Must be used within a DojoProvider component. * * @returns An object containing: * - setup: The Dojo setup configuration * - account: The current account information * @throws {Error} If used outside of a DojoProvider context + * @see DojoProvider + * @example + * ```tsx + * function GameComponent() { + * const { setup, account } = useDojo(); + * // Use setup and account... + * } + * ``` */examples/example-vite-react-sdk/src/main.tsx (3)
13-18: Enhance TypeDoc comment with more details.While the documentation is good, consider adding more specifics about:
- The configuration parameters required
- The expected error scenarios
- The return type (void/Promise)
/** * Initializes and bootstraps the Dojo application. * Sets up the SDK, burner manager, and renders the root component. * - * @throws {Error} If initialization fails + * @throws {Error} If SDK initialization fails, burner manager setup fails, or rendering fails + * @returns {Promise<void>} Resolves when the application is initialized and rendered */
Line range hint
39-48: Consider safer root element handling.The non-null assertion (
!) ongetElementByIdcould lead to runtime errors if the element is missing.Consider a safer approach:
- createRoot(document.getElementById("root")!).render( + const rootElement = document.getElementById("root"); + if (!rootElement) { + throw new Error("Failed to find root element"); + } + createRoot(rootElement).render(
Line range hint
50-52: Enhance error handling with user feedback.The current error handling only logs to console, which isn't visible to end users.
Consider adding user-visible error handling:
main().catch((error) => { console.error("Failed to initialize the application:", error); + // Display error to user + const rootElement = document.getElementById("root"); + if (rootElement) { + rootElement.innerHTML = ` + <div style="color: red; padding: 20px;"> + Failed to initialize the application. Please try refreshing the page. + </div> + `; + } });examples/example-vite-react-sdk/src/DojoContext.tsx (4)
12-21: Enhance interface documentation with more detailed property descriptions.While the current documentation is good, consider expanding the property descriptions to include:
- Usage examples
- Constraints or requirements
- Relationships between properties
/** * Interface defining the shape of the Dojo context. + * This interface encapsulates all necessary dependencies for Dojo operations. */ interface DojoContextType { - /** The master account used for administrative operations */ + /** + * The master account used for administrative operations. + * This account has elevated privileges and should be used carefully. + * @see Account from starknet for detailed usage + */ masterAccount: Account; - /** The Dojo client instance */ + /** + * The Dojo client instance for interacting with the contract. + * Generated from contract definitions and provides type-safe contract interactions. + */ client: ReturnType<typeof client>; - /** The current burner account information */ + /** + * The current burner account information. + * Contains both the account instance and management functions. + * Used for regular user operations. + */ account: BurnerAccount; }
24-27: Enhance context documentation with usage examples.Consider adding more comprehensive documentation including:
- Usage examples with hooks
- Provider requirements
- Error handling scenarios
/** * React context for sharing Dojo-related data throughout the application. + * + * @example + * // Using the context in a component + * const dojoContext = useContext(DojoContext); + * if (!dojoContext) { + * throw new Error("Component must be used within a DojoContextProvider"); + * } + * + * @remarks + * This context must be accessed within a DojoContextProvider component. + * The initial value is null, so consumers should always check for existence. */
29-35: Enhance error documentation and type safety.The TypeDoc comments are good, but consider adding:
- Return type annotation for the component
- More specific error scenarios in the documentation
/** * Provider component that makes Dojo context available to child components. * * @param props.children - Child components that will have access to the Dojo context * @param props.burnerManager - Instance of BurnerManager for handling burner accounts - * @throws {Error} If DojoProvider is used more than once in the component tree + * @throws {Error} If DojoProvider is nested within another DojoProvider + * @returns {JSX.Element} A context provider wrapping the children */ -export const DojoContextProvider = ({ +export const DojoContextProvider: React.FC<{ + children: ReactNode; + burnerManager: BurnerManager; +}> = ({
Line range hint
44-56: Add dependencies to useMemo and improve error handling.The empty dependency array in useMemo could cause stale values if the config changes. Also, the error message could be more helpful.
- if (currentValue) { - throw new Error("DojoProvider can only be used once"); + if (currentValue) { + throw new Error( + "DojoProvider is already present in the React tree. " + + "Ensure it's only used once at the root level." + ); } const masterAccount = useMemo( () => new Account( dojoProvider.provider, dojoConfig.masterAddress, dojoConfig.masterPrivateKey, "1" ), - [] + [ + dojoProvider.provider, + dojoConfig.masterAddress, + dojoConfig.masterPrivateKey + ] );examples/example-vite-react-sdk/src/bindings.ts (7)
1-14: Enhance type safety and documentation for the Moves interface.While the documentation is good, consider these improvements:
- Make
fieldOrdertype more specific using a tuple or readonly array of known fields- Add examples in the interface documentation
- Document the relationship between
can_moveandremaining/** * Interface representing a player's movement capabilities and state. + * + * @example + * const moves: Moves = { + * fieldOrder: ["player", "remaining", "last_direction", "can_move"], + * player: "0x123", + * remaining: 3, + * last_direction: Direction.Up, + * can_move: true + * }; */ interface Moves { /** Order of fields in the model */ - fieldOrder: string[]; + fieldOrder: readonly ["player", "remaining", "last_direction", "can_move"];
17-26: Apply similar type safety improvements to DirectionsAvailable interface.Consider the same type safety improvements as suggested for the Moves interface.
/** * Interface representing available movement directions for a player. + * + * @example + * const directions: DirectionsAvailable = { + * fieldOrder: ["player", "directions"], + * player: "0x123", + * directions: [Direction.Up, Direction.Right] + * }; */ interface DirectionsAvailable { /** Order of fields in the model */ - fieldOrder: string[]; + fieldOrder: readonly ["player", "directions"];
29-39: Apply consistent type safety improvements to Position interface.Maintain consistency with the previous interfaces by applying the same type safety improvements.
/** * Interface representing a player's position in the game world. + * + * @example + * const position: Position = { + * fieldOrder: ["player", "vec"], + * player: "0x123", + * vec: { x: 10, y: 20 } + * }; */ interface Position { /** Order of fields in the model */ - fieldOrder: string[]; + fieldOrder: readonly ["player", "vec"];
Line range hint
41-50: Enhance Direction enum documentation.Consider documenting the significance of the string values and their usage in the game context.
/** * Enum representing possible movement directions. + * + * The string values (0-4) are used for serialization in the game state. + * Direction.None (0) represents no movement or initial state. */
52-60: Consider enhancing Vec2 interface with constraints or utilities.If applicable to your game mechanics:
- Consider adding range constraints for coordinates
- Document any expected value ranges
- Consider adding readonly modifier if immutability is desired
interface Vec2 { /** X coordinate */ - x: number; + readonly x: number; /** Y coordinate */ - y: number; + readonly y: number; }
Line range hint
62-71: Enhance Schema type documentation.Consider adding more context about the dojo_starter namespace and its purpose in the game architecture.
/** * Type representing the complete schema of game models. + * + * All game models are namespaced under 'dojo_starter' to avoid + * conflicts with other systems and maintain clear boundaries. + * This schema is used by the Dojo store for state management. */
Line range hint
73-79: Enhance Models enum documentation.Add more context about how these model identifiers are used in the system.
/** * Enum representing model identifiers in the format "namespace-modelName". + * + * These identifiers are used to reference specific models in the Dojo store + * and maintain consistency across the application when querying or updating + * game state. */examples/example-vite-react-sdk/src/useSystemCalls.ts (3)
Line range hint
1-20: Add TypeScript types for better type safety.Consider adding TypeScript types for the state and returned objects to improve type safety and developer experience.
-export const useSystemCalls = () => { +interface SystemCallsHook { + spawn: () => Promise<void>; +} + +export const useSystemCalls = (): SystemCallsHook => {
6-12: Enhance TypeDoc documentation with more details.The documentation could be improved by:
- Explaining the optimistic update pattern
- Documenting error handling behavior
- Adding @throws annotation for potential errors
/** * Custom hook to handle system calls and state management in the Dojo application. * Provides functionality for spawning entities and managing optimistic updates. + * + * The hook implements optimistic updates to provide immediate feedback while + * waiting for blockchain confirmation. If the operation fails, the optimistic + * update is automatically reverted. * * @returns An object containing system call functions: * - spawn: Function to spawn a new entity with initial moves + * @throws {Error} When spawn operation fails or transaction is rejected */
Line range hint
29-74: Improve code maintainability and error handling.Several improvements can be made to enhance the code:
- Extract magic numbers to named constants
- Add safer property access
- Improve error messages
+const INITIAL_MOVES = 100; + const spawn = async () => { const entityId = generateEntityId(); const transactionId = uuidv4(); - const remainingMoves = 100; + const remainingMoves = INITIAL_MOVES; state.applyOptimisticUpdate(transactionId, (draft) => { - if (draft.entities[entityId]?.models?.dojo_starter?.Moves) { + const moves = draft.entities[entityId]?.models?.dojo_starter?.Moves; + if (moves) { draft.entities[entityId].models.dojo_starter.Moves.remaining = remainingMoves; } }); try { await client.actions.spawn({ account }); await state.waitForEntityChange(entityId, (entity) => { return ( entity?.models?.dojo_starter?.Moves?.remaining === remainingMoves ); }); } catch (error) { state.revertOptimisticUpdate(transactionId); - console.error("Error executing spawn:", error); + console.error(`Failed to spawn entity ${entityId}:`, error); throw error; } finally { state.confirmTransaction(transactionId); } };examples/example-vite-react-sdk/src/App.tsx (3)
11-13: Enhance store documentation with usage examples and type information.While the current documentation provides a basic description, consider expanding it to be more helpful for developers:
/** * Global store for managing Dojo game state. + * Created using createDojoStore with the game Schema. + * + * @example + * ```tsx + * const gameState = useDojoStore((state) => state); + * const entities = useDojoStore((state) => state.entities); + * ``` + * + * @type {ReturnType<typeof createDojoStore<Schema>>} */
16-21: Enhance component documentation with return type and hook usage.The documentation provides good context but could be more comprehensive:
/** * Main application component that provides game functionality and UI. * Handles entity subscriptions, state management, and user interactions. * + * @remarks + * Uses several hooks for state management and subscriptions: + * - useDojoStore for global state + * - useEffect for entity subscriptions and fetching + * - useMemo for computing entityId * * @param props.sdk - The Dojo SDK instance configured with the game schema + * @returns {JSX.Element} A React component rendering the game UI with controls and entity table */
Line range hint
22-280: Consider architectural improvements for better maintainability.The implementation is solid, but consider these architectural improvements:
- Extract the entity subscription and fetching logic into a custom hook (e.g.,
useEntitySync)- Move the UI components (burner management, movement controls, entity table) into separate components
- Create a dedicated types file for common interfaces and types
This would improve code organization and reusability.

Line range hint 19-38: Add configuration validation.
The SDK initialization uses configuration values directly without validation.
Let's check the dojoConfig structure:
Consider adding configuration validation:
function validateConfig(config: typeof dojoConfig) {
const required = ['rpcUrl', 'toriiUrl', 'relayUrl', 'manifest'];
for (const field of required) {
if (!config[field]) {
throw new Error(`Missing required configuration: ${field}`);
}
}
}
// Add before SDK init:
validateConfig(dojoConfig);examples/example-vite-react-sdk/src/DojoContext.tsx (1)
Line range hint 58-78: Verify cleanup of provider resources.
The implementation looks correct. However, let's verify that there are no memory leaks from the provider setup.
examples/example-vite-react-sdk/src/bindings.ts (1)
Line range hint 81-103: Schema implementation looks good!
The schema constant provides sensible default values and the exports include all necessary types for external usage.

Line range hint 34-74: Verify consistent optimistic update handling.
Let's ensure that optimistic updates and error handling are consistent across all system calls in the codebase.
✅ Verification successful
Based on the search results, I can now provide a final response since I have sufficient information about the optimistic update patterns and error handling across the codebase:
Optimistic update handling is consistent and well-implemented
The optimistic update pattern in the spawn function follows the established pattern from the SDK implementation (packages/sdk/src/state/zustand.ts), which includes:
- Proper transaction ID generation
- Consistent use of
applyOptimisticUpdate,revertOptimisticUpdate, andconfirmTransaction - Error handling in a try-catch block with proper cleanup
- Using the finally block to confirm successful transactions
The error handling also aligns with the codebase-wide pattern of:
- Reverting optimistic updates on failure
- Logging the error with context
- Re-throwing for proper error propagation
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Search for other optimistic update patterns to ensure consistency
rg -A 5 'applyOptimisticUpdate|revertOptimisticUpdate|confirmTransaction' --type ts
# Look for similar error handling patterns
rg -A 5 'catch \(error\)' --type ts

🛠️ Refactor suggestion
Add input validation for account address.
The function should validate that the account address exists before attempting to generate an entity ID.
const generateEntityId = () => {
+ if (!account?.address) {
+ throw new Error('No account address available');
+ }
return getEntityIdFromKeys([BigInt(account?.address)]);
