Adding a Live Generate Button: Why Synchronous Beat a Job Queue

Short summary

The author chose synchronous execution over async job queues for a content-draft generator, accepting 3–8 second latency to provide immediate user feedback—a practical trade-off for personal tools. A MAX_PENDING cap prevents draft accumulation by enforcing review before generation. The next improvements would be streaming (progressive rendering) and multi-platform batch requests rather than a full async queue.

• •Synchronous endpoints can deliver better UX for small tools despite blocking if latency is acceptable.
• •A draft cap (MAX_PENDING) enforces review discipline rather than allowing infinite accumulation.
• •Streaming is the next step, not a job queue—progressive rendering beats slower polling.
