Building a Reusable Input Component
Learn to simplify large forms by creating a reusable, customizable input component that handles labels, validation messages, and value changes efficiently.
We'll cover the following...
As our forms grow — think of sign-up pages, settings dashboards, or checkout flows — we’ll notice repeating patterns: labels, placeholders, input elements, and validation messages. Copying this logic everywhere leads to bloated code that’s hard to maintain.
React’s component-based architecture gives us a better way — we can extract this repeated logic into a reusable input component that accepts props for things like label, value, onChange, and error. This keeps our form code clean and consistent while reducing duplication.
Understanding reusable input components
A reusable input component acts as a controlled wrapper around a native <input>. It takes props from its parent (like value, onChange, label, and error) to keep data flow predictable and consistent.
Here’s the key flow:
