How can I handle errors in a TypeScript context API application?

You can handle errors in a TypeScript context API application by using try-catch blocks and custom error boundaries.

Can you give me an example of using a try-catch block?

Sure! You can wrap your API call in a try-catch block like this:

try {
  const response = await fetch('/api/data');
  const data = await response.json();
} catch (error) {
  console.error('Error fetching data:', error);
}

What about using custom error boundaries?

Custom error boundaries can be created by defining a class component that implements componentDidCatch to catch errors in its child components.

How do I implement a custom error boundary?

You can implement a custom error boundary like this:

class ErrorBoundary extends React.Component {
  state = { hasError: false };

  static getDerivedStateFromError(error) {
    return { hasError: true };
  }

  componentDidCatch(error, errorInfo) {
    console.error('Error caught in ErrorBoundary:', error, errorInfo);
  }

  render() {
    if (this.state.hasError) {
      return <h1>Something went wrong.</h1>;
    }
    return this.props.children;
  }
}
