What are the best practices for using Context API with TypeScript?

When using Context API with TypeScript, it's important to define your context types clearly. This helps in maintaining type safety.

Can you give me an example of how to define context types?

Sure! You can create an interface for your context value and then use it when creating your context. For example:

interface MyContextType {
  value: string;
  updateValue: (newValue: string) => void;
}

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

How do I handle default values in my context?

You can provide default values by using a provider component. For instance:

const MyProvider: React.FC = ({ children }) => {
  const [value, setValue] = useState('default');
  const updateValue = (newValue: string) => setValue(newValue);

  return <MyContext.Provider value={{ value, updateValue }}>{children}</MyContext.Provider>;
};

What about using multiple contexts?

When using multiple contexts, it's best to create separate providers for each context and nest them in your component tree. This keeps your code organized and manageable.
