Main event: a robust, asynchronous background-task system decouples browser interaction from data ingestion, using a resilient job queue and observable status updates to the user.

Common pitfalls are avoided by steering clear of synchronous pagination, honoring rate limit headers, and managing token expiry during long migrations.

Introduction: social media import pipelines fail due to third‑party rate limits and front‑end synchronization; the solution requires resilient UX and background processing.

Practical implementation includes a BullMQ-based worker, a React hook for progress, and an Express route to initiate the import, showing how to pass payloads and manage cursors.

Takeaways: separate migrations from the browser, utilize real-time event streams, account for rate limits and tokens, and treat failures as recoverable.

Production checklist: incorporate idempotency keys, cancelable UI actions, and non-blocking behavior during large downloads.

Frontend UX pattern: use a persistent status drawer with real-time updates via WebSockets or SSE, delivering adaptive progress and clear failure messaging.

Problem analysis: synchronous requests and naive spinners cause poor UX, orphaned records, and loss of trust during outages or slow networks.

Step-by-step integration: a frontend hook (useSocialImport) streams via SSE, and a backend orchestrator route (/api/imports/start) initializes jobs and streams status.

Backend architecture: a scalable, concurrent BullMQ-based worker system processes imports in batches with backoff and rate-limit awareness.
