Frontend build fails due to duplicate handleWebSocketMessage and missing parseContent in Game.tsx

[Abhishek2005-ard]

Description

The frontend fails to compile due to multiple issues in Game.tsx related to WebSocket message handling.

Issues Identified

1. handleWebSocketMessage is declared twice in the same file.
2. One declaration contains invalid syntax (}, [] )) which breaks compilation.
3. The function parseContent is used but not defined or imported.
4. This results in TypeScript / Vite build errors.

Expected Behavior

The frontend should compile successfully and handle WebSocket messages using a single, valid handleWebSocketMessage implementation.

Actual Behavior

Build fails with syntax and reference errors.

Suggested Fix

• Remove the duplicate handleWebSocketMessage declaration.
• Keep the useCallback version.
• Add a helper function like:

  function parseContent<T>(content: string, type: string): T | null {
    try {
      return JSON.parse(content) as T;
    } catch (error) {
      console.error(`Failed to parse content for ${type}:`, error);
      return null;
    }
  }

Hi , I'm a GSoC 2026 candidate and I'd like to fix this build blocker.

My plan is to:

Refactor Game.tsx: I will remove the duplicate and syntactically broken handleWebSocketMessage declaration while keeping the useCallback version to maintain proper React performance.

Implement parseContent: I will add the suggested parseContent helper function with TypeScript generics to ensure type safety and handle JSON parsing errors gracefully.

Verify the Build: I will run the Vite build locally to confirm that all syntax and reference errors are resolved and the frontend compiles successfully.

I can have a PR ready for this today. Please assign this to me!

Hi maintainers, I would like to work on this issue if it’s still unassigned.

Summary (what’s breaking)

• Game.tsx has two handleWebSocketMessage declarations; one includes invalid syntax, so TypeScript/Vite can’t compile.
• parseContent is referenced but not defined/imported, causing a reference error.

Proposed approach

1. Remove the duplicate/broken handleWebSocketMessage
   • Keep the useCallback version (stable reference, correct React pattern).
   • Ensure the callback dependency list is correct to avoid stale state/handlers.
2. Introduce a small typed parseContent helper
   • Add it near the WebSocket handling code (or in a shared utils file if that’s the repo convention).
   • Return T | null on parse failure and log with message type for debugging.
3. Update call-sites to handle null safely
   • Guard before accessing parsed fields to prevent runtime crashes.
4. Verify and document
   • Run lint/typecheck (if present) and build locally.
   • Confirm the frontend compiles and WebSocket message handling still works as expected.

Implementation sketch

function parseContent<T>(content: string, type: string): T | null {
  try {
    return JSON.parse(content) as T;
  } catch (error) {
    console.error(`Failed to parse content for ${type}:`, error, content);
    return null;
  }
}

Deliverable

• A PR that fixes the build and references this issue (Fixes #136), with a short note on how to reproduce/verify.

If someone is already actively working on it, please let me know and I’ll pick another issue to avoid duplicate effort. Otherwise, I’m happy to take it on.

Thanks for the clear analysis and proposed solution. I’m planning to work on this issue and will follow the approach mentioned above. I’ll open a PR once the fix is ready.
