  1. Nice post, wish when I read all these forms in react blogs though that they’d include nice ways the include validation

  2. Great article 👍
    There is a small typo in the first example. You entered username.. probably ment email

  3. I think, the approach you used for get data using FormData, it’s antipattern in react. Please see controlled components vs uncontrolled components.

  4. I think what the author is trying to say throughout the article is that in simple cases, the overhead of controlled components doesn’t bring any additional benefits. Just using uncontrolled components alone isn’t an anti pattern.

  5. Hi ,
    I use a custom hook, but the problem is that I also have a large list in the component. When I do the onChange operation, this list becomes re render again and greatly reduces performance.

  6. Your code works fine until a checkbox is added. The formData doesn’t seem to return a true/false value.

    const formData = new FormData(e.target as HTMLFormElement);

    The formData.get(‘registerMe’) returns ‘on’ instead of true/false. I cannot think of any other way except to access the checkbox value directly:


    So wouldn’t it be better to access the elements directly rather than through the FormData? You already have a reference to the form and can access the values.
