Don't overthink it. Native HTML5 elements come with form validation and even a way to serialize (!) and submit form data w/ action and method attributes. (To implement the same as React components would be a 3 month project coming with a 1 GiB node_modules dir.) The only time you have to add JS bloat is for date pickers and time pickers which aren't supported on Safari yet (and you can user agent sniff for this).

Blows my mind why some people choose to adopt megabytes of dependencies when you can just write a few HTML tags and have it executed by the browser's C++ engine instead of some JavaScript nightmare.
