How can I use hooks with the Context API in React?
You can use the useContext
hook to access context values in your functional components. Would you like an example?
Yes, please provide a code example.
Sure! Here's a simple example:
import React, { createContext, useContext, useState } from 'react';
const MyContext = createContext();
const MyProvider = ({ children }) => {
const [value, setValue] = useState('Hello, World!');
return <MyContext.Provider value={{ value, setValue }}>{children}</MyContext.Provider>;
};
const MyComponent = () => {
const { value } = useContext(MyContext);
return <div>{value}</div>;
};
const App = () => (
<MyProvider>
<MyComponent />
</MyProvider>
);
export default App;
What if I want to update the context value?
You can use the setValue
function from the context to update the value. For example:
const MyComponent = () => {
const { value, setValue } = useContext(MyContext);
return (
<div>
<p>{value}</p>
<button onClick={() => setValue('New Value')}>Update Value</button>
</div>
);
};
