Advanced Features and Best Practices

Once you've mastered the basics of ROAARRR, it's time to explore some of the more advanced features that can significantly boost your productivity.

Advanced Configuration

Custom Webpack Configuration

You can extend the default webpack configuration by creating a roaarrr.config.js file:

module.exports = {
  webpack: (config) => {
    config.module.rules.push({
      test: /\.svg$/,
      use: ['@svgr/webpack']
    })
    return config
  }
}

Environment Variables

Manage your environment variables effectively:

# .env.local
DATABASE_URL=your_database_url
API_KEY=your_api_key

Performance Optimization

Code Splitting

Implement code splitting to improve your application's loading performance:

import dynamic from 'next/dynamic'

const DynamicComponent = dynamic(() => import('./HeavyComponent'), {
  loading: () => <p>Loading...</p>
})

Image Optimization

Use ROAARRR's built-in image optimization:

import Image from 'roaarrr/image'

export default function MyComponent() {
  return (
    <Image
      src="/hero-image.jpg"
      alt="Hero Image"
      width={800}
      height={600}
      priority
    />
  )
}

Testing Strategies

Unit Testing

Write comprehensive unit tests:

import { render, screen } from '@testing-library/react'
import MyComponent from './MyComponent'

test('renders component correctly', () => {
  render(<MyComponent />)
  expect(screen.getByText('Hello World')).toBeInTheDocument()
})

Integration Testing

Test your API endpoints:

import { testApiHandler } from 'next-test-api-route-handler'
import handler from './api/users'

describe('/api/users', () => {
  it('returns user data', async () => {
    await testApiHandler({
      handler,
      test: async ({ fetch }) => {
        const res = await fetch({ method: 'GET' })
        expect(res.status).toBe(200)
      }
    })
  })
})

Security Best Practices

1. Input Validation: Always validate user input
2. Authentication: Implement proper authentication mechanisms
3. HTTPS: Use HTTPS in production
4. Dependencies: Keep dependencies updated

Deployment Strategies

Vercel Deployment

Deploy to Vercel with zero configuration:

npx vercel --prod

Docker Deployment

Create a Dockerfile for containerized deployment:

FROM node:18-alpine
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production
COPY . .
RUN npm run build
EXPOSE 3000
CMD ["npm", "start"]

Conclusion

By implementing these advanced features and best practices, you'll be able to build more robust, performant, and maintainable applications with ROAARRR.
