|
|
|
### REFERENCIAS A CONSULTAR

|
|
2. `frontend/src/components/Layout.tsx` - Layout principal
|
|
3. `frontend/src/index.css` - Estilos globales
|
|
4. `frontend/src/contexts/` - Contextos existentes
|
|
|
|
### ESTRATEGIA
|
|
- Usar `darkMode: 'class'` en Tailwind
|
|
- Toggle agrega/quita clase `dark` en `<html>`
|
|
- Persistir en localStorage
|
|

### INSTRUCCIONES
|
|
1. Modificar `tailwind.config.js`:
|
|
- Agregar `darkMode: 'class'`
|
|
|
|
2. Crear `ThemeContext.tsx`:
|
|
```typescript
|
|
interface ThemeContextType {
|
|
theme: 'light' | 'dark' | 'system';
|
|
setTheme: (theme: 'light' | 'dark' | 'system') => void;
|
|
resolvedTheme: 'light' | 'dark';
|
|
}
|
|
```
|
|
|
|
3. Modificar `Layout.tsx`:
|
|
- Agregar botón de toggle en header
|
|
- Usar iconos Sun/Moon
|
|
|
|
4. Actualizar `index.css`:
|
|
- Agregar variables CSS para dark mode
|
|
- Colores base para ambos temas
|
|
|
|
5. Agregar clases dark: en componentes principales:
|
|
- `dark:bg-gray-900`
|
|
- `dark:text-white`
|
|

|
|
|
|

### Cambios Implementados
|
|
|
|
1. **Tailwind Config:**
|
|
```javascript
|
|
module.exports = {
|
|
darkMode: 'class',
|
|
// ...
|
|
}
|
|
```
|
|
|
|
2. **ThemeContext:**
|
|
```typescript
|
|
export const ThemeProvider = ({ children }) => {
|
|
const [theme, setTheme] = useState<'light' | 'dark' | 'system'>(() => {
|
|
return localStorage.getItem('theme') || 'system';
|
|
});
|
|
|
|
useEffect(() => {
|
|
const root = document.documentElement;
|
|
const isDark = theme === 'dark' ||
|
|
(theme === 'system' && window.matchMedia('(prefers-color-scheme: dark)').matches);
|
|
|
|
root.classList.toggle('dark', isDark);
|
|
localStorage.setItem('theme', theme);
|
|
}, [theme]);
|
|
|
|
return (
|
|
<ThemeContext.Provider value={{ theme, setTheme, resolvedTheme }}>
|
|
{children}
|
|
</ThemeContext.Provider>
|
|
);
|
|
};
|
|
```
|
|
|
|
3. **Toggle Button:**
|
|
```tsx
|
|
<button onClick={toggleTheme}>
|
|
{resolvedTheme === 'dark' ? <Sun /> : <Moon />}
|
|
</button>
|
|
```
|
|
|
|
4. **CSS Variables:**
|
|
```css
|
|
:root {
|
|
--background: #ffffff;
|
|
--foreground: #171717;
|
|
}
|
|
.dark {
