# Route Fix for Published App

## Problem
When publishing the app to a static hosting service (like GitHub Pages), accessing the root URL `/` results in "Cannot GET /" error. This happens because:

1. The app uses React Router for client-side routing
2. Static hosting servers don't understand client-side routes
3. When a user accesses `/`, the server looks for a physical file at that path
4. The server returns 404 because there's no file matching that route

## Solution Applied

### 1. Created `public/_redirects` File
This file tells compatible static hosts (Netlify, Render, etc.) to redirect all routes to `index.html`:

```
/*    /index.html   200
```

### 2. Created `public/404.html` 
For hosts like GitHub Pages that use a 404 page, this file captures the route and stores it in sessionStorage:

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Redirecting...</title>
    <script>
        sessionStorage.redirect = location.href;
    </script>
    <meta http-equiv="refresh" content="0;URL='/'" />
</head>
<body>
    <p>Redirecting...</p>
</body>
</html>
```

### 3. Updated `index.html`
Added a script to restore the route from sessionStorage after the redirect:

```html
<script>
    (function() {
        var redirect = sessionStorage.redirect;
        delete sessionStorage.redirect;
        if (redirect && redirect !== location.href) {
            history.replaceState(null, null, redirect);
        }
    })();
</script>
```

## How It Works

1. User accesses `https://your-app.github.io/dashboard`
2. GitHub Pages returns 404 (no physical file at that path)
3. GitHub Pages serves `404.html` instead
4. `404.html` stores the URL in sessionStorage and redirects to `/`
5. `index.html` loads with the React app
6. The script in `index.html` reads sessionStorage and updates the URL
7. React Router sees `/dashboard` in the URL and renders the correct route

## Enhanced Console Logging

Added comprehensive trace logging throughout the initialization flow:

### App Initialization (`App.tsx`)
- Current URL, pathname, search, hash
- Seed data loading progress
- App ready state
- Component preloading status

### Route Configuration (`routes.tsx`)
- Enabled pages list with details
- Root page detection
- Route creation with paths

### Router Provider (`RouterProvider.tsx`)
- Feature toggles state
- State and action context keys
- Routes memo updates
- Individual route rendering

### Page Loader (`page-loader.ts`)
- Page configuration loading
- Enabled pages filtering
- Props resolution for each state/action
- Keyboard shortcuts configuration

## Verification

To verify the fix works:

1. Build the app: `npm run build`
2. Serve the `dist` folder with a static server
3. Navigate to `/` - should load the home page
4. Navigate to `/dashboard` - should load dashboard
5. Refresh on `/dashboard` - should stay on dashboard (not 404)

## Trace Console Output

You can now trace the full initialization flow in the browser console:

```
[INIT] 🚀 main.tsx starting - BEGIN
[INIT] 📦 Importing React DOM
[INIT] ✅ React DOM imported

[APP] 🚀 App component initializing
[APP] 🌐 Current URL: https://...

```

## Additional Notes

- The root route `/` is configured in `src/config/pages.json` with `"isRoot": true`
- The home page uses the `ProjectDashboard` component
- All routes are dynamically generated from the JSON configuration
- The console logs include emojis and structured prefixes for easy filtering
