Web forms are an important aspect of web development as they are used to interact with users. For instance, they can collect user data through sign-ups/ins or sending messages.
You can create forms in React from scratch. However, that approach will consume a lot of your time. Luckily, you can use ready-made forms packaged in the form of libraries.
React form libraries are a collection of pre-designed forms you can import into your React applications. Such libraries help you save time and are created to be responsive to different screen sizes.
These are some of the reasons to use React form libraries;
Simplified form management: Forms are used to collect user data. In a typical form submission process, the state changes a lot. For instance, when a user signs in, the state changes from a visitor to a logged user. React form libraries provide a simpler way to manage these forms, from handling submissions and validation to state management.
Integration with UI frameworks: Most React form libraries integrate with popular UI component frameworks like Material UI and Bootstrap. You can thus use forms from such frameworks and enjoy consistent styling in your forms.
Easy validation: Most React form libraries allow flexible validation of your forms. Validation can happen at the form or input level.
Error handling and feedback: Most libraries provide features for highlighting error messages. You can thus get alerts when your forms fail and know why.
These are the best React form libraries you can start using today;
React Hook Form
React Hook Form is a performant and extensible forms library with an easy-to-use validation. This open-source library is available for web and mobile apps through React Native.
Performant: Forms created using this library are small and fast. React Hook Form does away with unnecessary re-renders.
Supports validation: React Hook Form allows you to add validation to your forms to ensure users submit valid data. For instance, you can set the minimum number of characters for a password or describe the email format needed.
Comes with a form creator: Instead of relying on and editing existing components, this library gives you control over form creation. The templates are already styled; you can add and delete fields effortlessly.
Comprehensive APIs: Depending on your needs, you can use different React Hook Forms APIs. For instance, you can use </>useController API in your controlled forms. On the other hand, you can use the </>useFormState to enable individual form state updates.
