Building Scalable APIs with Upgrade

When building modern web applications, having a solid API architecture is crucial. In this tutorial, we’ll explore best practices for creating scalable APIs using Upgrade CMS as your content backend.

Understanding the Content API

Upgrade CMS provides a powerful GraphQL and REST API out of the box. Here’s how to leverage both effectively.

REST API Basics

// Fetching all blog posts
const response = await fetch('https://api.upgrade.dev/v1/posts', {
  headers: {
    'Authorization': `Bearer ${API_KEY}`,
    'Content-Type': 'application/json'
  }
});

const posts = await response.json();

GraphQL Queries

query GetPosts($limit: Int!, $offset: Int!) {
  posts(limit: $limit, offset: $offset) {
    id
    title
    content
    author {
      name
      avatar
    }
    publishedAt
  }
}

Caching Strategies

Edge Caching

Implement edge caching to reduce latency:

1. Use CDN for static content
2. Set appropriate cache headers
3. Implement stale-while-revalidate patterns

Application-Level Caching

import { createCache } from '@upgrade/cache';

const cache = createCache({
  ttl: 3600, // 1 hour
  maxSize: 100 // MB
});

export async function getPosts() {
  const cached = await cache.get('posts');
  if (cached) return cached;
  
  const posts = await fetchPosts();
  await cache.set('posts', posts);
  return posts;
}

Rate Limiting

Protect your API with intelligent rate limiting:

• Tier 1: 100 requests/minute for free users
• Tier 2: 1000 requests/minute for pro users
• Tier 3: Unlimited for enterprise

Conclusion

Building scalable APIs requires careful planning and the right tools. Upgrade CMS provides the foundation you need to build robust, performant applications.

Happy coding! 🚀
