Json Editor
JSON Editor is a schema-driven UI framework and web-based editor used to generate interactive forms and validate JSON data. It translates JSON Schema specifications into a hierarchy of HTML form elements, allowing users to manipulate complex JSON structures through a structured interface rather than raw text.
The framework differentiates itself through a plugin-based extension system that supports custom resolver functions and the integration of specialized editors, such as WYSIWYG, Markdown, and syntax-highlighted code editors. It employs recursive schema resolution to handle nested definitions and implements state-based conditional validation using if-then-else logic.
The project provides a broad range of capabilities including bidirectional data binding, array and object layout management for grids and tabs, and dynamic field syncing via template interpolation. Its component library covers standard inputs alongside specialized tools like color pickers, date-time pickers, autocomplete components, and file upload interfaces.
The interface supports localization of UI strings and integrates with various CSS frameworks to decouple structural form generation from visual styling.
Features
- Schema-Driven Generators - Automatically generates a hierarchy of HTML form elements and input controls based on JSON Schema definitions.
- Declarative UI Schemas - Functions as a schema-driven UI framework that maps declarative data structures to interactive form components.
- Form Builders - Provides a framework for creating interactive forms with conditional logic, custom resolvers, and dynamic field values.
- Plugin-Based Input Extensions - Provides a plugin system for registering custom resolver functions and UI components for specialized data types.
- JSON Forms - Provides a framework for automatically generating dynamic web forms from JSON schema specifications.
- Conditional Validation Rules - Applies dynamic validation rules using if-then-else logic based on the current values of other form fields.
- Schema Validators - Verifies that current form values conform to predefined JSON Schema rules and flags invalid entries.
- Schema Reference Resolution - Resolves internal and external JSON pointers to load schema definitions from remote URLs or local sources.
- Bidirectional Data-Binding - Synchronizes the internal JSON data model with the DOM state via programmatic getters and setters.
- Standard Input Controls - Generates standard HTML form inputs for strings, integers, and numbers based on JSON Schema types.
- JSON Schema Editors - Provides a browser-based interface for editing complex JSON structures guided by a schema and integrated validation.
- Specialized Editor Integrations - Integrating specialized editors such as WYSIWYG, Markdown, or code editors into a schema-driven form workflow.
- Markdown Editors - Embeds a dedicated markdown editor component for authoring and formatting string content.
- Visual Array Layouts - Renders JSON arrays as interactive tables, tabs, or multi-select lists to improve data entry efficiency.
- Template Interpolation - Uses a template engine to update field labels and values in real-time based on other input states.
- Dynamic Configuration Interfaces - Enables the creation of administrative panels for editing complex JSON settings through a structured UI.
- Value Change Triggers - Implements callbacks that trigger specific actions whenever a form field value is modified.
- Custom Validation Rules - Allows the injection of user-defined logic into the validation engine to enforce custom data formats.
- Embedded Third-Party Editors - Embeds specialized third-party editors for WYSIWYG HTML, Markdown, and syntax-highlighted code within the generated forms.
- Code Editor Components - Integrates full-featured code editor components with syntax highlighting for various programming and markup languages.
- Complex Form Layouts - Simplifies complex JSON data entry by rendering nested objects and arrays as tables, tabs, and grids.
- Dynamic Field Syncing - JSON Editor updates specific field values automatically based on other inputs using a JavaScript template engine.
- Custom Resolver Components - Allows registering custom resolver functions and UI components to handle specialized data types.
- Rich Text WYSIWYG Editors - Integrates rich text WYSIWYG editors for HTML, BBCode, and general visual formatting.
- Schema-Driven Input Rendering - Automatically renders specialized inputs such as color pickers and date pickers based on the format defined in the JSON schema.
- CSS Framework Mapping - Decouples form generation from visual styling by mapping structural elements to various CSS framework classes.
- Form Layout Management - Allows precise control over the visual arrangement of fields using grids, tabs, and custom property ordering.
- Cross-Field Dependency Links - Implements logic that triggers updates or visibility changes in form fields based on the state of other inputs.
- Data Utilities and Libraries - JSON Schema-based form editor.
