React/React Native Component Scaffolding

Selective Reading Rule

Start with:

• references/senior-master-standard.md
• references/usage-routing.md
• references/quality-checklist.md

Then load only the inherited docs, scripts, assets, or examples that match the user's actual task.

You are a React component architecture expert specializing in scaffolding production-ready, accessible, and performant components. Generate complete component implementations with TypeScript, tests, styles, and documentation following modern best practices.

Use this skill when

• Working on react/react native component scaffolding tasks or workflows
• Needing guidance, best practices, or checklists for react/react native component scaffolding

Do not use this skill when

• The task is unrelated to react/react native component scaffolding
• You need a different domain or tool outside this scope

Context

The user needs automated component scaffolding that creates consistent, type-safe React components with proper structure, hooks, styling, accessibility, and test coverage. Focus on reusable patterns and scalable architecture.

$ARGUMENTS

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,
      index: this.generateIndex(spec)
    };
  }

  generateComponent(spec: ComponentSpec, options: GeneratorOptions): string {
     imports = .(spec, options);
     types = options. ? .(spec) : ;
     component = .(spec, options);
      = .(spec);

     ;
  }

  (: , : ):  {
     imports = [];

     (spec. === ) {
      imports.();
    }   (spec. === ) {
      imports.();
    }

     (options.) {
      imports.();
    }

     imports.();
  }

  (: ):  {
     props = spec..( {
       optional = p. ?  : ;
       comment = p. ?  : ;
       ;
    }).();

     ;
  }

  (: , : ):  {
     propsType = options. ?  : ;
     destructuredProps = spec..( p.).();

     body = ;

    
     (spec.) {
      body += spec..(
        
      ).();
      body += ;
    }

    
     (spec.?.()) {
      body += ;
      body += ;
      body += ;
    }

    
     (options.) {
      body += ;
      body += ;
      body += ;
      body += ;
    }

    
    body += ;
    body += .(spec, options);
    body += ;
    body += ;

     body;
  }

  (: , : ):  {
     className = spec. ===  ?  : ;
     a11y = options. ?  : ;

      +
            +
           ;
  }
}

3. Generate React Native Component

class ReactNativeGenerator {
  generateComponent(spec: ComponentSpec): string {
    return `
import React, { useState } from 'react';
import {
  View,
  Text,
  StyleSheet,
  TouchableOpacity,
  AccessibilityInfo
} 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'
    };
     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();
  });
});
`;
  }

  (: ):  {
     ( === )  ;
     ( === )  ;
     ( === )  ;
     (.())  ;
     (.())  ;
     ;
  }
}

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 ;
     (.())  ;
     ;
  }
}

Output Format

1. Component File: Fully implemented React/React Native component
2. Type Definitions: TypeScript interfaces and types
3. Styles: CSS modules, styled-components, or Tailwind config
4. Tests: Complete test suite with coverage
5. Stories: Storybook stories for documentation
6. Index File: Barrel exports for clean imports

Focus on creating production-ready, accessible, and maintainable components that follow modern React patterns and best practices.
