Worker độc lập khi cần routing phức tạp Standalone Worker for complex routing
Dùng Worker khi cần middleware, auth edge, hoặc nhiều hostname. Worker là đơn vị compute linh hoạt nhất. Use a Worker when you need middleware, edge auth, or multiple hostnames. Workers are the most flexible compute unit.
Các bước thực hiện Step-by-step
- `wrangler init` hoặc dashboard Create Worker. `wrangler init` or dashboard Create Worker.
- Viết fetch handler: routing theo pathname/hostname. Write fetch handler: route by pathname/hostname.
- Deploy `wrangler deploy` — gán custom domain hoặc route `*.example.com/*`. Deploy with `wrangler deploy` — attach custom domain or route `*.example.com/*`.
- Dùng `wrangler tail` khi debug. Use `wrangler tail` when debugging.
Giải thích chi tiết Detailed explanation
Worker độc lập phù hợp middleware toàn zone, BFF, hoặc multi-tenant routing — linh hoạt hơn Pages Functions. Standalone Workers suit zone-wide middleware, BFFs, or multi-tenant routing — more flexible than Pages Functions.
Lưu ý (best practices) Note (best practices)
Custom domain: Worker là origin, DNS/SSL tự động. Route: Worker chạy trước origin — cần DNS record proxied (orange cloud); thiếu record sẽ gây ERR_NAME_NOT_RESOLVED. Custom domain: the Worker is the origin with automatic DNS/SSL. Route: the Worker runs in front of an origin — you need a proxied DNS record (orange cloud); missing records cause ERR_NAME_NOT_RESOLVED.
