How can I define TypeScript types for the Context API?

You can define TypeScript types for the Context API by creating an interface for your context value and using it in your context provider.

Can you show me an example of that?

Sure! First, define an interface like this:

interface MyContextType {
  user: string;
  isAuthenticated: boolean;
}

Then, create your context:

const MyContext = createContext<MyContextType | undefined>(undefined);

What about using the context in a component?

In your component, you can use the useContext hook like this:

const context = useContext(MyContext);
if (!context) {
  throw new Error('useContext must be used within a MyProvider');
}

Thanks! This is really helpful.
