  • TypeScript: Typing Form Events In React

    TypeScript: Typing Form Events In React

    Updated on · 9 min read

    Handling events in React is very close to how the events on DOM elements are handled. The biggest difference is, however, that React wraps the native DOM events into SyntheticEvent, making them behave slightly differently than the native events. Consequently, typing form events in React is not the same as native events. In this post, we'll see how to type form events in React on the example of a simple component as well as discuss the most common pitfalls.
