Usage & Trade-offs
All fields support markdown. Use concise bullets and concrete situations.
When to use it
*
Use Cloudflare Workers when: - Building edge-side rendering or API proxies. - Needing global distribution without server management. - Handling custom logic for web traffic (e.g., A/B testing). - Integrating with Cloudflare's CDN and security features.
Pros
*
- Sub-millisecond cold starts and edge proximity. - Free tier with generous request limits. - V8 isolates for secure, isolated execution. - Easy deployment via Wrangler CLI. - Integrates with KV storage and Durable Objects.
Cons
*
- 10ms CPU time limit on free plan; bursts cost extra. - Limited to JavaScript/WebAssembly runtime. - Debugging distributed code can be challenging. - Vendor lock-in to Cloudflare ecosystem. - No persistent state without additional services.
Notes
Note: Use Workers for KV for simple key-value caching at edge. Monitor with Cloudflare Analytics for performance. Test locally with miniflare for faster iteration.
