Best Practices

Follow these guidelines for optimal performance, security, and maintainability.

Performance Optimization

Caching Strategy

Use ISR for Dynamic Content

Implement Incremental Static Regeneration for content that changes occasionally but needs to be fast.

Cache API Responses

Set appropriate cache headers and use Next.js revalidation to balance freshness and performance.

Optimize Images

Use Next.js Image component with DCloud.dev's automatic image optimization and WebP conversion.

Code Example: Optimized Data Fetching

// Optimized data fetching with caching
export async function getStaticProps() {
  const articles = await fetchArticles();
  
  return {
    props: { articles },
    revalidate: 300, // Revalidate every 5 minutes
  }
}

// Use React.memo for expensive components
const ArticleCard = React.memo(({ article }) => {
  return (
    <div className="article-card">
      <Image
        src={article.image}
        alt={article.title}
        width={400}
        height={200}
        priority={article.featured}
      />
      <h3>{article.title}</h3>
    </div>
  )
})

Security Best Practices

API Security

Validate Input Data

Always validate and sanitize data from APIs before using it in your application.

Use Environment Variables

Store sensitive configuration in environment variables, never in code.

Implement Rate Limiting

Protect your API endpoints from abuse with proper rate limiting.

Security Checklist

HTTPS everywhere

Secure headers configured

Input validation

Regular security updates

Access control implemented

Error handling secure

TypeScript Best Practices

Define Proper Types

Create interfaces for all API responses and component props.

Use Strict Mode

Enable strict TypeScript settings for better type safety.

Generate Types from Schema

Use GraphQL code generation for type-safe API calls.

Data Management

GraphQL Best Practices

Request Only What You Need

Use GraphQL's field selection to minimize data transfer and improve performance.

Use Fragments for Reusability

Define GraphQL fragments for commonly used field sets.

Implement Pagination

Use cursor-based pagination for large datasets.

Example: Efficient GraphQL Query

// Define reusable fragments
const ARTICLE_FRAGMENT = gql`
  fragment ArticleFields on NodeArticle {
    id
    title
    summary
    created
    author {
      displayName
    }
  }
`;

// Use fragments in queries
const GET_ARTICLES = gql`
  query GetArticles($first: Int!, $after: String) {
    nodeArticles(first: $first, after: $after) {
      edges {
        node {
          ...ArticleFields
        }
      }
      pageInfo {
        hasNextPage
        endCursor
      }
    }
  }
  ${ARTICLE_FRAGMENT}
`;
