What are some tips for async validation with Formik?

When using Formik for async validation, consider these tips: 1. Use the validate function for async checks. 2. Debounce input to reduce validation calls. 3. Handle loading states to improve user experience.

How can I debounce the validation calls?

You can use a debounce function from libraries like Lodash. Wrap your validation logic in a debounce function to limit how often it runs.

What if I need to validate multiple fields asynchronously?

You can return a promise from your validate function that checks multiple fields. Just ensure to handle the results properly.

Are there any common pitfalls to avoid?

Yes, avoid making too many async calls in quick succession, and ensure your validation logic is efficient to prevent performance issues.
