Optimistic UI Updates That Never Lie to the User

说明与用途

即时 UI 反馈与诚实回滚和清晰错误信息提升用户信任，降低感知延迟。

问题

Users experience broken interactions when UI updates are delayed or silently revert after a failed server request.

结果

Instant UI feedback with honest rollback and informative errors improves user trust and reduces perceived latency.

工作流

• 1. Capture current liked state and stash it.
• 2. Toggle liked state locally and render immediately.
• 3. Call API to persist change. - If success: do nothing further. - If failure: retry with backoff up to 3 attempts. 4. If all retries fail: restore stashed state, render, and display error message.
• 5. Provide a manual retry button in the error message to re‑run the optimistic flow.

证据

Optimistic UI shows the result in under 16ms, before the server replies

Show a specific error on failure, not a silent revert

Retry with backoff beats a dead button after one failed request
