Automatic Front-end Disaster Recovery Solution Overview

For front‑end development, page rendering depends on static assets and API data; API responses are the most failure‑prone, so front‑end disaster recovery focuses on safeguarding API data.

When an API request fails, the system returns fallback data to keep the page functional.

The solution is packaged as an npm tool with a visual backend for managing and analyzing disaster‑recovery data.

Integration is low‑cost, though backup data still requires developers to trigger it.

Manual backup is infeasible for APIs with numerous parameter variations, prompting the need for automatic backup generation.

Key questions: which requests need automatic backup, how to ensure backup accuracy, and how to control which APIs are backed up.

Several automatic backup strategies were evaluated; the chosen approach generates backup data on‑demand when a fallback request finds no existing backup, accepting occasional first‑failure gaps.

Optimizations include a visual whitelist for target APIs, static parameter settings to limit unnecessary backups, syncing backup results to responsible developers, and a one‑click recovery option for non‑automatic cases.

After deployment, front‑end disaster‑recovery coverage rose from ~30% to ~70%, with 80% of backup data generated automatically, significantly improving stability.

Future work includes monitoring backend API anomalies, enhancing data freshness for prefetch and performance optimization, and establishing feedback loops for API quality.
