How can I use a theme provider with TypeScript?

You can use a theme provider in TypeScript by creating a context for your theme and using it with a provider component.

Can you show me a code example?

Sure! Here's a simple example:

import React, { createContext, useContext, ReactNode } from 'react';

interface ThemeContextType {
  theme: string;
  setTheme: (theme: string) => void;
}

const ThemeContext = createContext<ThemeContextType | undefined>(undefined);

const ThemeProvider: React.FC<{ children: ReactNode }> = ({ children }) => {
  const [theme, setTheme] = React.useState('light');

  return (
    <ThemeContext.Provider value={{ theme, setTheme }}>
      {children}
    </ThemeContext.Provider>
  );
};

const useTheme = () => {
  const context = useContext(ThemeContext);
  if (!context) {
    throw new Error('useTheme must be used within a ThemeProvider');
  }
  return context;
};

export { ThemeProvider, useTheme };

What if I want to add more themes?

You can extend the state in your ThemeProvider to include multiple themes and update the setTheme function accordingly.
