React/React Native Component Scaffolding

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.

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 {
    const imports = this.generateImports(spec, options);
    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}`;
