How can I implement async validation in my forms?
An example of an AI chatbot conversation about testing async validation in forms.
How can I implement async validation in my forms?
You can implement async validation by using promises in your validation function. This allows you to check the validity of input against a server or database.
Can you give me an example of how to do that?
Sure! You can create a function that returns a promise, which resolves if the input is valid or rejects if it's not. For instance, checking if a username is already taken.
What libraries can help with async validation?
Libraries like Formik and React Hook Form provide built-in support for async validation, making it easier to manage forms.
