Which architecture patterns enable cloud api integration in React.js applications?
The architecture patterns that enable cloud api integration in React.js applications include BFF layers, gateway aggregation, event-driven designs, and robust caching.
1. Backend for Frontend (BFF)
- A UI‑specific service shapes endpoints to screen needs and device constraints.
- Payloads shrink by composing data from multiple domains into UI‑ready JSON.
- UI complexity drops as the BFF owns auth, rate limits, and schema evolution.
- Latency improves via server‑side caching, batching, and connection pooling.
- Security strengthens with token handling offloaded from the browser surface.
- Evolution stays flexible as UI changes avoid broad backend rewrites.
2. GraphQL federation and caching
- A unified schema spans multiple services through gateway composition.
- Clients request exact fields, reducing overfetch and underfetch penalties.
- Performance benefits from persisted queries, CDN caching, and APQ.
- Type safety increases with codegen for hooks, fragments, and operations.
- Governance centralizes with schema checks, lint rules, and change contracts.
- Resilience improves through query timeouts, retries, and partial data strategies.
3. Event‑driven patterns with webhooks and queues
- UIs react to domain events via webhooks, SSE, or pub/sub channels.
- Backpressure protection appears through queues, dead letters, and replays.
- Perceived speed improves using optimistic updates and eventual consistency notes.
- Spikes smooth with buffering, fan‑out consumers, and auto‑scale targets.
- Audit needs meet with immutable logs, correlation IDs, and event schemas.
