FAQs

Error Boundaries are used to handle errors in class components. The most easy and effective way to handle problems that occur within your React components is to use error boundaries. If you use class component, you may construct an error boundary component by inserting the life cycle method componentDidCatch(error, info).

After you've made the api call, the server (assuming you're also building the server) should check to see if the name and phone number are already in use. The server should return an error if they already exist. After your API call, capture the error in your react app and assign it to your error state variable.
