Writing Sustainable AsyncAPI Generator Templates
summary
Shows that AsyncAPI Generator templates must be written as frameworks/libraries using inversion of control rather than as files you edit: with AsyncAPI Generator (AG, ~40,000 weekly npm downloads) and a Node.js/Mosquitto MQTT demo the original template overwrites handlers on regeneration and destroys user business logic. Replaces file-editing handlers with an exported API to register middleware (Express‑style), generates a runnable streetlights app from a spec, and proves regeneration adds channels without losing user code.
