 This document outlines planned improvements and future directions for the Spix project.
 
+## Phase 1: Core Refinements & Branding
+
+1.  **Project Renaming:**
+    *   Update project name in `package.json` from `perplexity_ai_react_clone` to `spix`.
+    *   Update title in `index.html` from `Perplexity` to `Spix`.
+    *   Update any internal branding references (e.g., header in `Nav.tsx`) to "Spix".
+    *   Update `README.md` to reflect the new project name and purpose.
+2.  **Code Cleanup & Linting:**
+    *   Address any remaining ESLint/TypeScript warnings or errors.
+    *   Review component structure for potential improvements.
+
+## Phase 2: Multi-Model Integration Backend
+
+1.  **Backend API Route:**
+    *   Create a backend API route (e.g., `/api/generate`) to handle AI requests securely. This is necessary because API keys for different providers should not be exposed directly in the frontend.
+    *   This route will act as a proxy between the Spix frontend and the various AI provider APIs.
+2.  **Environment Variables:**
+    *   Ensure all necessary API keys (OpenAI, Anthropic, Google GenAI, etc.) are configured as server-side environment variables (e.g., in Vercel project settings, not prefixed with `VITE_`).
+3.  **Provider Logic:**
+    *   Implement logic within the API route to:
+        *   Accept a desired provider/model name as input (e.g., `openai/gpt-4o`, `anthropic/claude-3-7-sonnet-20250219`, `google/gemini-2.5-pro-exp-03-25`).
+        *   Select the correct API key based on the provider.
+        *   Format the request according to the specific provider's API requirements (e.g., different message structures, parameters).
+        *   Call the appropriate provider's API.
+        *   Standardize the response format returned to the frontend.
+4.  **Initial Model Support:**
+    *   Implement support for OpenAI (`gpt-4o`), Anthropic (`claude-3-7-sonnet-20250219`), and Google (`gemini-2.5-pro-exp-03-25`) via the backend route.
+
+## Phase 3: Frontend Integration & Model Selection
+
+1.  **Refactor Frontend API Call:**
+    *   Update `src/pages/Result.tsx` (`callOpenAI` function) to call the new backend API route (`/api/generate`) instead of `api.openai.com` directly.
+    *   Pass the desired model identifier to the backend route.
+2.  **Model Selection UI (Optional):**
+    *   Consider adding a UI element (e.g., a dropdown) to allow users to select which model they want to use for their query.
+    *   Alternatively, implement automatic model selection logic based on criteria like query complexity (this is more advanced).
+3.  **Vercel AI SDK / Responses API (Optional):**
+    *   Evaluate migrating the backend API route to use the Vercel AI SDK or potentially the OpenAI Responses API (if library support becomes available or if using a different SDK) for features like streaming, better state management, and structured outputs.
+
+## Phase 4: Advanced Features & Deployment
+
+1.  **Streaming Responses:**
+    *   Implement streaming support using the Vercel AI SDK or native provider capabilities via the backend route to display results progressively.
+2.  **Conversation History:**
+    *   Implement proper conversation history management, passing relevant context to the backend API route for multi-turn interactions.
+3.  **Tool Use / Agents:**
+    *   Explore integrating tools (like web search) or agentic capabilities using relevant SDKs (e.g., OpenAI Agents SDK, Vercel AI SDK tools).
+4.  **Deployment:**
+    *   Ensure all backend and frontend changes are correctly configured and deployed on Vercel, including server-side environment variables.

     *   **Action Item:** Attempt further fixes (e.g., check package versions, simplify tsconfig, test alternative import strategies).
 *   **Deployment Planning:** Define detailed steps for Vercel deployment, including environment variable setup, build configuration, and testing. Evaluate Cloud Run/Firebase if necessary.

body: Hey @GaryOcean428 - I've reviewed your changes - here's some feedback:

**Overall Comments**:
- Consider using a state management library like Zustand or Jotai for managing global app state instead of React Context.
- The localStorage reads and writes are scattered throughout the codebase; consider centralizing them into a dedicated service.

body: **suggestion (bug_risk):** Event listener removal may be ineffective.

Since the added event listener is an anonymous inline function, the removal call creates a new function instance, which does not remove the previously attached listener. Consider defining the event handler as a named function or storing it in a variable so that the same reference can be used for both addEventListener and removeEventListener.

Suggested implementation:

```typescript
        return () => input?.removeEventListener("keydown", handleKeyDown)

```

```typescript
        // Define the event handler once so that it can be both attached and removed.
        const handleKeyDown = (event: KeyboardEvent) => {
            if (event.key === "Enter") {
                navigate(`/result?query=${input.value}`);
                context.setShowModal(false);
            }
        };

        input?.addEventListener("keydown", handleKeyDown);

```

If there are other inline references to the anonymous event listener (for example, if it is defined elsewhere in the file), be sure to replace them with the new handleKeyDown to ensure consistency. Ensure that the type for event (KeyboardEvent) is either imported or globally available depending on your TypeScript configuration.

body: **issue (complexity):** Consider extracting localStorage operations into a separate helper function to simplify the loadResult function and reduce nested try/catch blocks.

You can simplify `loadResult` by extracting localStorage operations into a separate helper. This reduces nested try/catch blocks and makes the function’s purpose clearer. For example:

```ts
function saveThread(query: string, resultContent: string) {
  try {
    const threads: Threads = JSON.parse(localStorage.getItem("threads") || "{}");
    const threadId = generateUUID();
    threads[threadId] = {
      query,
      result: resultContent,
      createdAt: new Date().toISOString(),
    };
    localStorage.setItem("threads", JSON.stringify(threads));
  } catch (storageError) {
    console.error("Failed to save result to localStorage:", storageError);
  }
}
```

Then refactor `loadResult` as follows:

```ts
const loadResult = async (currentQuery: string) => {
  if (!currentQuery) {
    setError("No query provided.");
    setIsLoading(false);
    return;
  }
  setIsLoading(true);
  setError(null);
  setTitle(currentQuery);
  try {
    const resultContent = await callOpenAI(currentQuery);
    setResult(resultContent);
    saveThread(currentQuery, resultContent);
  } catch (err: unknown) {
    console.error("Failed to load result:", err);
    setError(err instanceof Error ? err.message : "An unexpected error occurred.");
    setResult("");
  } finally {
    setIsLoading(false);
  }
};
```

These changes isolate the localStorage responsibility and reduce the complexity within `loadResult` while keeping functionality intact.

## PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

<table>
<tr><td>⏱️&nbsp;<strong>Estimated effort to review</strong>: 3 🔵🔵🔵⚪⚪</td></tr>
<tr><td>🧪&nbsp;<strong>No relevant tests</strong></td></tr>
<tr><td>🔒&nbsp;<strong>Security concerns</strong><br><br>

<strong>API Key Exposure:</strong><br> The OpenAI API key is being loaded from environment variables with the VITE_ prefix (VITE_OPENAI_API_KEY) in Result.tsx. This means the key is bundled with the client-side code and exposed to users. According to the roadmap, there are plans to move this to a backend API route, but in the current implementation, this is a security vulnerability. API keys should never be exposed in client-side code.</td></tr>

The useEffect in App.tsx adds event listeners to inputRef.current but the cleanup function doesn't properly remove the specific event handler, potentially causing memory leaks.

The error handling in loadResult function catches errors but doesn't provide specific handling for different error types (network errors, API errors, etc.) which could improve user experience.

    console.error("Failed to load result:", err);

<details><summary>Remove conflicting API implementations</summary>

___


**The <code>callOpenAI</code> function contains two conflicting implementations. It first <br>attempts to call the OpenAI API directly, then tries to call a backend API route <br>with the same variable name <code>response</code>. This will cause the first implementation <br>to be overwritten and never used. You should remove one of these implementations <br>based on your roadmap.**

[src/pages/Result.tsx [31-62]](https://github.com/GaryOcean428/spix/pull/1/files#diff-55e8da664a68b7a6c6237232f310e84e09df131d6870334e1a7ff21573b202feR31-R62)

<details><summary>Remove extra closing brace</summary>

___


**There's a syntax error in the <code>callOpenAI</code> function. The function has an extra <br>closing curly brace after the fetch call, which will cause a compilation error. <br>This needs to be removed to ensure the function works correctly.**

[src/pages/Result.tsx [61-72]](https://github.com/GaryOcean428/spix/pull/1/files#diff-55e8da664a68b7a6c6237232f310e84e09df131d6870334e1a7ff21573b202feR61-R72)

Secure API key exposure<!-- not_implemented -->
</summary>

___


**Exposing the OpenAI API key directly in the frontend is a critical security <br>vulnerability. According to the roadmap, API keys should be handled securely in <br>a backend route. Move this API call to a backend endpoint to prevent exposing <br>your API key to clients.**

[src/pages/Result.tsx [61-69]](https://github.com/GaryOcean428/spix/pull/1/files#diff-55e8da664a68b7a6c6237232f310e84e09df131d6870334e1a7ff21573b202feR61-R69)

`[Suggestion has been applied]`

<details><summary>Suggestion importance[1-10]: 10</summary>

__

Why: This is a critical security vulnerability. Exposing API keys in frontend code makes them accessible to anyone who inspects the page, potentially leading to unauthorized API usage and financial costs. The roadmap explicitly mentions moving API calls to a backend route for security.

<details><summary>✅ 
Prevent localStorage quota errors<!-- not_implemented -->
</summary>

___


**The code is storing potentially large AI responses in localStorage without any <br>size limits, which could lead to exceeding the 5MB localStorage limit. Implement <br>a mechanism to limit the number of stored threads or their size to prevent <br>localStorage quota errors.**

[src/pages/Result.tsx [193-207]](https://github.com/GaryOcean428/spix/pull/1/files#diff-55e8da664a68b7a6c6237232f310e84e09df131d6870334e1a7ff21573b202feR193-R207)

```diff
 const threads: Threads = JSON.parse(localStorage.getItem("threads") || "{}");
-
 const threadId = generateUUID();
 
+// Add new thread
 threads[threadId] = {
+    query: currentQuery,
+    result: resultContent,
+    createdAt: new Date().toISOString()
+};
 
-    query: currentQuery,
-
-    result: resultContent,
-
-    createdAt: new Date().toISOString()
-
-};
+// Limit storage size by keeping only the most recent threads
+const MAX_THREADS = 20;
+const threadIds = Object.keys(threads);
+if (threadIds.length > MAX_THREADS) {
+    // Sort by date and remove oldest
+    const sortedIds = threadIds.sort((a, b) => 
+        new Date(threads[b].createdAt).getTime() - new Date(threads[a].createdAt).getTime()
+    );
+    const idsToRemove = sortedIds.slice(MAX_THREADS);
+    idsToRemove.forEach(id => delete threads[id]);
+}
 
 localStorage.setItem("threads", JSON.stringify(threads));
```

`[Suggestion has been applied]`

<details><summary>Suggestion importance[1-10]: 7</summary>

__

Why: This suggestion addresses a potential issue where the application could exceed localStorage's 5MB limit by storing unlimited AI responses. Implementing a mechanism to limit stored threads is important for preventing quota errors and maintaining application functionality.

<details><summary>Handle null localStorage value</summary>

___


**The localStorage.getItem() call could return null if the item doesn't exist, <br>which would cause a runtime error when using strict equality (===) with "true". <br>Add a nullish coalescing operator to provide a default value.**

[src/App.tsx [74]](https://github.com/GaryOcean428/spix/pull/1/files#diff-26ad4b834941d9b19ebf9db8082bd202aaf72ea0ddea85f5a8a0cb3c729cc6f2R74-R74)

```diff
-const [isProfileSetup, setIsProfileSetup] = useState(localStorage.getItem("isProfileSetup") === "true"); // Use ===
+const [isProfileSetup, setIsProfileSetup] = useState(localStorage.getItem("isProfileSetup") ?? "false" === "true");
```

 <!-- /improve --apply_suggestion=0 -->

<details><summary>Suggestion importance[1-10]: 8</summary>

__

Why: This suggestion correctly identifies a potential runtime error when using strict equality with a value that could be null. Adding the nullish coalescing operator provides a fallback value, preventing potential crashes.

<details><summary>Fix dependency array</summary>

___


**The dependency array contains <code>context?.isProfileSetup</code> which uses the optional <br>chaining operator. React's dependency array should contain only variables, not <br>expressions with operators. This can cause the effect to not re-run properly <br>when the context changes.**

[src/components/Nav.tsx [18-35]](https://github.com/GaryOcean428/spix/pull/1/files#diff-7f2ef60bbec771e3e2a3e1e7162d91e481d7724cd76ea86a82a0b4ad45c3baefR18-R35)

```diff
 useEffect(() => {
     // Access context properties only if context is not null
     if (context?.isProfileSetup) {
         const userString = localStorage.getItem("user");
         if (userString) {
             try {
                 setProfile(JSON.parse(userString));
             } catch (e) {
                 console.error("Failed to parse user from localStorage:", e);
                 // Optionally clear corrupted data
                 // localStorage.removeItem("user");
             }
         }
     } else {
         setProfile(null); // Clear profile if not setup
     }
-    // Depend on context?.isProfileSetup to re-run effect when context becomes available or changes
-}, [context?.isProfileSetup]);
+    // Depend on context to re-run effect when context becomes available or changes
+}, [context]);
```

 <!-- /improve --apply_suggestion=1 -->

<details><summary>Suggestion importance[1-10]: 7</summary>

__

Why: The suggestion correctly identifies a React hooks dependency issue. Using expressions with operators in dependency arrays can cause unexpected behavior, so changing to depend on the entire context object improves reliability of the effect.
