​
JSON Editor Component

The JSON Editor component provides a direct interface for editing the underlying JSON schema of a view. It offers syntax highlighting, validation, and auto-completion to help users edit schemas efficiently.

​
Features

  • Syntax Highlighting: Color-coded JSON for better readability
  • Schema Validation: Real-time validation against the view schema specification
  • Auto-Completion: Suggestions for schema properties and values
  • Error Highlighting: Visual indication of syntax and validation errors
  • Format Controls: Options to format, minify, and copy JSON

​
Basic Usage

import { JSONEditor } from '@repo/view-builder/json-editor/JSONEditor';
import { SchemaProvider } from '@repo/view-builder/hooks/useSchemaState';

function MyJSONEditor() {
  return (
    <SchemaProvider>
      <JSONEditor />
    </SchemaProvider>
  );
}

​
Editor Controls

The JSON Editor includes the following controls:

  • Format: Format the JSON for better readability
  • Validate: Validate the JSON against the schema specification
  • Copy: Copy the JSON to the clipboard
  • Reset: Reset the JSON to the last valid state
  • Apply: Apply changes to the schema

​
Customization

You can customize the editor appearance and behavior:

<JSONEditor
  theme="dark"
  readOnly={false}
  height="500px"
  showLineNumbers={true}
  formatOnPaste={true}
/>

​
Integration with Schema State

The JSON Editor automatically syncs with the schema state:

import { JSONEditor } from '@repo/view-builder/json-editor/JSONEditor';
import { useSchemaState } from '@repo/view-builder/hooks/useSchemaState';

function SchemaEditor() {
  const { schema, setSchema } = useSchemaState();
  
  const handleChange = (newSchema) => {
    setSchema(newSchema);
  };
  
  return <JSONEditor value={schema} onChange={handleChange} />;
}

​
Advanced Usage

​
Custom Schema Validation

You can provide custom validation rules:

import { JSONEditor } from '@repo/view-builder/json-editor/JSONEditor';

const customValidationRules = [
  {
    rule: (schema) => schema.fields && Object.keys(schema.fields).length > 0,
    message: 'Schema must contain at least one field'
  },
  {
    rule: (schema) => schema.type === 'form' || schema.type === 'table' || schema.type === 'detail',
    message: 'Schema type must be one of: form, table, detail'
  }
];

function ValidatedEditor() {
  return <JSONEditor validationRules={customValidationRules} />;
}

​
Schema Templates

You can provide predefined schema templates:

import { JSONEditor } from '@repo/view-builder/json-editor/JSONEditor';

const schemaTemplates = {
  emptyForm: {
    type: 'form',
    schema: 'user',
    fields: {}
  },
  emptyTable: {
    type: 'table',
    schema: 'user',
    columns: []
  },
  emptyDetail: {
    type: 'detail',
    schema: 'user',
    sections: []
  }
};

function TemplatedEditor() {
  return <JSONEditor templates={schemaTemplates} />;
}

​
Custom Actions

You can add custom actions to the editor:

import { JSONEditor } from '@repo/view-builder/json-editor/JSONEditor';

const customActions = [
  {
    label: 'Generate Types',
    icon: 'code',
    action: (schema) => {
      // Generate TypeScript types from schema
      console.log('Generating types for schema:', schema);
    }
  },
  {
    label: 'Export to File',
    icon: 'download',
    action: (schema) => {
      // Export schema to file
      const blob = new Blob([JSON.stringify(schema, null, 2)], { type: 'application/json' });
      const url = URL.createObjectURL(blob);
      const a = document.createElement('a');
      a.href = url;
      a.download = 'schema.json';
      a.click();
    }
  }
];

function ActionableEditor() {
  return <JSONEditor customActions={customActions} />;
}
