📱 Mobile App Templates

React Native Component

Intermediate
React Native

Reusable React Native component with proper styling.

import React from 'react'; import { View, Text, StyleSheet, TouchableOpacity } from 'react-native'; const $COMPONENT_NAME$ = ({ title, onPress, style }) => { return ( {title} ); }; const styles = StyleSheet.create({ container: { padding: 15, backgroundColor: '#667eea', borderRadius: 8, shadowColor: '#000', shadowOffset: { width: 0, height: 2, }, shadowOpacity: 0.25, shadowRadius: 3.84, elevation: 5, }, title: { color: 'white', fontSize: 16, fontWeight: 'bold', textAlign: 'center', }, }); export default $COMPONENT_NAME$;

🔄 DevOps Templates

Docker Compose Template

Advanced
Docker

version: '3.8' services: app: build: . ports: - "3000:3000" environment: - NODE_ENV=production - DATABASE_URL=postgresql://user:password@db:5432/app_db depends_on: - db - redis networks: - app-network db: image: postgres:13 environment: - POSTGRES_DB=app_db - POSTGRES_USER=user - POSTGRES_PASSWORD=password volumes: - postgres_data:/var/lib/postgresql/data ports: - "5432:5432" networks: - app-network redis: image: redis:7-alpine ports: - "6379:6379" networks: - app-network volumes: postgres_data: networks: app-network: driver: bridge

🛠️ Creating Your Own Templates

Build reusable templates to accelerate your development workflow:

Step 1: Identify Patterns

  • Look for code you write repeatedly
  • Identify common project structures
  • Note frequently used configurations

Step 2: Abstract Variables

// Use placeholders like $VARIABLE_NAME$ // Example: const $COMPONENT_NAME$ = () => { ... };

Step 3: Document Usage

  • Create README files for each template
  • Include usage examples and customization options
  • Maintain version history

Step 4: Version Control

  • Store templates in Git repositories
  • Use semantic versioning for releases
  • Test templates before using in production
