  • Gathering user input without forms is possible, but forms make things simpler
  • What are forms?
  • Forms are the typical method we user input required to interact with an ecosystem
    • Highly opinionated
    • Many ways to do them
  • Security, validation, accessibility etc.

    • Working with What We Have in React and Javascript/HTML
    • Controlled vs Uncontrolled
    • Validation
      • preventing server side hacking
      • ensuring validity of data
      • checking each field on submission
      • regex
  • Where vanilla react forms fail?
    • large swathes of setStates or managing a large state object
    • multiple types of validation, shared validation
    • lots of vanilla code to cover existing and potentially future cases
    • you end up just creating your own form framework, so why not use an existing one?
