Drag & Drop Form Builder Library for React.
Optimajet FormEngine helps developers create and render dynamic forms in React with a JSON-based approach. It combines a drag-and-drop form builder, a client-side React library, and ready-to-use UI components, with support for reusable forms, validation, localization, responsive layouts, built-in actions, and custom component integration.

JSON-Driven Form Rendering

Renders forms in React from a JSON definition that can describe structure, logic, styling, validation, and actions. This approach supports configuration-driven development and makes forms easier to store, reuse, transfer, and update across applications.

Drag-And-Drop Form Builder

Provides a visual form builder for creating forms through drag-and-drop interaction instead of hand-coding every field. Developers can design and modify form layouts visually, then use the generated form definition in React applications.

React Form Library

Includes a lightweight client-side React library that renders dynamic forms directly in the application. It is designed for building simple and complex forms with minimal code while keeping the form definition separate from presentation logic.

Ready-To-Use UI Components

Offers a component library optimized for use with the form engine and builder. It includes common interface elements such as inputs, dropdowns, date pickers, uploaders, tabs, navigation elements, progress indicators, and multi-step form components.

Custom Component Integration

Allows developers to define and integrate custom React components by specifying their name, type, and properties. This makes it possible to extend the default form capabilities and align the rendered form with application-specific behavior or design requirements.

Built-In Validation

Supports validation rules, required fields, and error messages directly in code or JSON. This helps developers define form behavior in one place and also allows integration with third-party validation libraries when broader validation logic is needed.

Built-In Actions

Handles common form actions such as submit, reset, and external calls as part of the form definition. Developers can configure the actions needed for a given form without building separate handling logic for each standard interaction.

Localization Support

Includes built-in support for multilingual form experiences. Forms can be prepared for multiple languages from the start, and developers can also connect third-party localization libraries when a project needs a broader internationalization setup.

Responsive Layout And Dynamic Styling

Supports responsive layout behavior and dynamic CSS so forms can adapt to different devices and presentation needs. This helps keep the same form usable across varying screen sizes without requiring separate layout implementations.

Programmatic Form Generation

Lets developers build or modify forms in real time using code or external data sources. This is useful for applications that assemble forms dynamically based on user role, workflow state, configuration data, or changing business rules.
