When Are Form Builders Useful?

Form builders are particularly useful when you're dealing with complex forms that have a lot of fields, nested attributes, and validations. They abstract away a lot of the repetitive tasks involved in constructing these forms and allow developers to focus on more important things.

If you're building an application using JavaScript, chances are you'd be using npm to manage your project dependencies. Using npm, you can install a form builder package and start using it right away. This wouldn't just save development time but also ensure you're following the best practices when it comes to form handling in JavaScript applications.

For instance, tasks like validation rules definition, error messages handling, nested forms management, fields association, among others, can be much simpler and standardized across the application.

Functionalities of Form Builders

Form builders typically come with the following functionalities:

1. Dynamic Form Rendering: Ability to dynamically render forms based on metadata.

2. Form Validations: Ability to define validation rules and enforce them on the form inputs.

3. Event Handling: Handle form events based on user interactions like click or input changes.

4. Field Customization: Option to customize form field types, including text boxes, radio buttons, checkboxes, dropdowns, etc.

5. Data Binding: Ability to bind data to form fields and keep them in sync with the state.

6. Nested Forms: Support for creating complex forms with nested fields.

7. Template Features: Templates to generate form structure and layout, including responsiveness for mobile screens.

Gotchas/Pitfalls to Watch Out For

While form builders offer convenience and reduce development time, there are some potential pitfalls you need to be aware of:

1. Over-reliance: Do not totally rely on a form builder for all aspects of form management. Understand that form builders abstract away many things for the sake of convenience, which might not always be ideal for your specific use case.

2. Customization Limitations: Often, the ease-of-use comes at the expense of customizability. You must be aware of what custom options are available and how far you can stretch the builder to suit your needs.

3. Learning Curve: Form builders can have a steep learning curve, and reading the documentation well is important.

4. Bundle Size: Form builders can be quite big in size and can affect the overall size of your application bundle. Make sure you do some analysis on the size increment with such a package included.

5. Compatibility Issues: Make sure the form builder is compatible with your tech stack and the package versions you're using.

Always remember to maintain a balance between the in-built module and customization to ascertain seamless development processes.
