Instructions

1. Analyze Component Requirements

interface ComponentSpec {

  name: string;

  type: 'functional' | 'page' | 'layout' | 'form' | 'data-display';

  props: PropDefinition[];

  state?: StateDefinition[];

  hooks?: string[];

  styling: 'css-modules' | 'styled-components' | 'tailwind';

  platform: 'web' | 'native' | 'universal';

}

interface PropDefinition {

  name: string;

  type: string;

  required: boolean;

  defaultValue?: any;

  description: string;

}

class ComponentAnalyzer {

  parseRequirements(input: string): ComponentSpec {

    // Extract component specifications from user input

    return {

      name: this.extractName(input),

      type: this.inferType(input),

      props: this.extractProps(input),

      state: this.extractState(input),

      hooks: this.identifyHooks(input),

      styling: this.detectStylingApproach(),

      platform: this.detectPlatform()

    };

  }

}

2. Generate React Component

interface GeneratorOptions {

  typescript: boolean;

  testing: boolean;

  storybook: boolean;

  accessibility: boolean;

}

class ReactComponentGenerator {

  generate(spec: ComponentSpec, options: GeneratorOptions): ComponentFiles {

    return {

      component: this.generateComponent(spec, options),

      types: options.typescript ? this.generateTypes(spec) : null,

      styles: this.generateStyles(spec),

      tests: options.testing ? this.generateTests(spec) : null,

      stories: options.storybook ? this.generateStories(spec) : null,

    const types = options.typescript ? this.generatePropTypes(spec) : '';

    const component = this.generateComponentBody(spec, options);

    const exports = this.generateExports(spec);

    return `${imports}\n\n${types}\n\n${component}\n\n${exports}`;

  }

  generateImports(spec: ComponentSpec, options: GeneratorOptions): string {

    const imports = ["import React, { useState, useEffect } from 'react';"];

    if (spec.styling === 'css-modules') {

      imports.push(`import styles from './${spec.name}.module.css';`);

    } else if (spec.styling === 'styled-components') {

      imports.push("import styled from 'styled-components';");

    }

    if (options.accessibility) {

      imports.push("import { useA11y } from '@/hooks/useA11y';");

    }

    return imports.join('\n');

  }

  generatePropTypes(spec: ComponentSpec): string {

    const props = spec.props.map(p => {

      const optional = p.required ? '' : '?';

      const comment = p.description ? `  /** ${p.description} */\n` : '';

      return `${comment}  ${p.name}${optional}: ${p.type};`;

    }).join('\n');

    return `export interface ${spec.name}Props {\n${props}\n}`;

  }

  generateComponentBody(spec: ComponentSpec, options: GeneratorOptions): string {

    const propsType = options.typescript ? `: React.FC<${spec.name}Props>` : '';

    const destructuredProps = spec.props.map(p => p.name).join(', ');

    let body = `export const ${spec.name}${propsType} = ({ ${destructuredProps} }) => {\n`;

    // Add state hooks

    if (spec.state) {

      body += spec.state.map(s =>

        `  const [${s.name}, set${this.capitalize(s.name)}] = useState${options.typescript ? `<${s.type}>` : ''}(${s.initial});\n`

      ).join('');

      body += '\n';

    }

    // Add effects

    if (spec.hooks?.includes('useEffect')) {

      body += `  useEffect(() => {\n`;

      body += `    // TODO: Add effect logic\n`;

      body += `  }, [${destructuredProps}]);\n\n`;

    }

    // Add accessibility

    if (options.accessibility) {

      body += `  const a11yProps = useA11y({\n`;

      body += `    role: '${this.inferAriaRole(spec.type)}',\n`;

      body += `    label: ${spec.props.find(p => p.name === 'label')?.name || `'${spec.name}'`}\n`;

      body += `  });\n\n`;

    }

    // JSX return

    body += `  return (\n`;

  }

  generateJSX(spec: ComponentSpec, options: GeneratorOptions): string {

    const className = spec.styling === 'css-modules' ? `className={styles.${this.camelCase(spec.name)}}` : '';

    const a11y = options.accessibility ? '{...a11yProps}' : '';

    return `    <div ${className} ${a11y}>\n` +

           `      {/* TODO: Add component content */}\n` +

} from 'react-native';

interface ${spec.name}Props {

${spec.props.map(p => `  ${p.name}${p.required ? '' : '?'}: ${this.mapNativeType(p.type)};`).join('\n')}

}

export const ${spec.name}: React.FC<${spec.name}Props> = ({

  ${spec.props.map(p => p.name).join(',\n  ')}

}) => {

  return (

    <View

      style={styles.container}

      accessible={true}

      accessibilityLabel="${spec.name} component"

    >

      <Text style={styles.text}>

        {/* Component content */}

      </Text>

    </View>

  );

};

const styles = StyleSheet.create({

  container: {

    flex: 1,

    padding: 16,

    backgroundColor: '#fff',

  },

  text: {

    fontSize: 16,

    color: '#333',

  },

});

`;

  }

  mapNativeType(webType: string): string {

    const typeMap: Record<string, string> = {

      'string': 'string',

      'number': 'number',

      'boolean': 'boolean',

      'React.ReactNode': 'React.ReactNode',

      'Function': '() => void'

    };

    return typeMap[webType] || webType;

  }

}

4. Generate Component Tests

class ComponentTestGenerator {

  generateTests(spec: ComponentSpec): string {

    return `

import { render, screen, fireEvent } from '@testing-library/react';

import { ${spec.name} } from './${spec.name}';

describe('${spec.name}', () => {

  const defaultProps = {

${spec.props.filter(p => p.required).map(p => `    ${p.name}: ${this.getMockValue(p.type)},`).join('\n')}

  };

  it('renders without crashing', () => {

    render(<${spec.name} {...defaultProps} />);

    expect(screen.getByRole('${this.inferAriaRole(spec.type)}')).toBeInTheDocument();

  });

  it('displays correct content', () => {

    render(<${spec.name} {...defaultProps} />);

    expect(screen.getByText(/content/i)).toBeVisible();

  });

${spec.props.filter(p => p.type.includes('()') || p.name.startsWith('on')).map(p => `

  it('calls ${p.name} when triggered', () => {

    const mock${this.capitalize(p.name)} = jest.fn();

    render(<${spec.name} {...defaultProps} ${p.name}={mock${this.capitalize(p.name)}} />);

    const trigger = screen.getByRole('button');

    fireEvent.click(trigger);

    expect(mock${this.capitalize(p.name)}).toHaveBeenCalledTimes(1);

  });`).join('\n')}

  it('meets accessibility standards', async () => {

    const { container } = render(<${spec.name} {...defaultProps} />);

    const results = await axe(container);

    expect(results).toHaveNoViolations();

  });

});

`;

  }

  getMockValue(type: string): string {

    if (type === 'string') return "'test value'";

    if (type === 'number') return '42';

    if (type === 'boolean') return 'true';

    if (type.includes('[]')) return '[]';

    if (type.includes('()')) return 'jest.fn()';

    return '{}';

  }

}

5. Generate Styles

class StyleGenerator {

  generateCSSModule(spec: ComponentSpec): string {

    const className = this.camelCase(spec.name);

    return `

.${className} {

  display: flex;

  flex-direction: column;

  padding: 1rem;

  background-color: var(--bg-primary);

}

.${className}Title {

  font-size: 1.5rem;

  font-weight: 600;

  color: var(--text-primary);

  margin-bottom: 0.5rem;

}

.${className}Content {

  flex: 1;

  color: var(--text-secondary);

}

`;

  }

  generateStyledComponents(spec: ComponentSpec): string {

    return `

import styled from 'styled-components';

export const ${spec.name}Container = styled.div\`

  display: flex;

  flex-direction: column;

  padding: \${({ theme }) => theme.spacing.md};

  background-color: \${({ theme }) => theme.colors.background};

\`;

export const ${spec.name}Title = styled.h2\`

  font-size: \${({ theme }) => theme.fontSize.lg};

  font-weight: 600;

  color: \${({ theme }) => theme.colors.text.primary};

  margin-bottom: \${({ theme }) => theme.spacing.sm};

\`;

`;

  }

  generateTailwind(spec: ComponentSpec): string {

    return `

// Use these Tailwind classes in your component:

// Container: "flex flex-col p-4 bg-white rounded-lg shadow"

// Title: "text-xl font-semibold text-gray-900 mb-2"

// Content: "flex-1 text-gray-700"

`;

  }

}

6. Generate Storybook Stories

class StorybookGenerator {

  generateStories(spec: ComponentSpec): string {

    return `

import type { Meta, StoryObj } from '@storybook/react';

import { ${spec.name} } from './${spec.name}';

const meta: Meta<typeof ${spec.name}> = {

  title: 'Components/${spec.name}',

  component: ${spec.name},

  tags: ['autodocs'],

  argTypes: {

${spec.props.map(p => `    ${p.name}: { control: '${this.inferControl(p.type)}', description: '${p.description}' },`).join('\n')}

  },

};

export default meta;

type Story = StoryObj<typeof ${spec.name}>;

export const Default: Story = {

  args: {

${spec.props.map(p => `    ${p.name}: ${p.defaultValue || this.getMockValue(p.type)},`).join('\n')}

  },

};

export const Interactive: Story = {

  args: {

    ...Default.args,

  },

};

`;

  }

  inferControl(type: string): string {

    if (type === 'string') return 'text';

    if (type === 'number') return 'number';

    if (type === 'boolean') return 'boolean';

    if (type.includes('[]')) return 'object';

    return 'text';

  }

}
