Building Automation Systems with NestJS
summary
NestJS is used as a central backend that receives POSTs from Bob CRM, writes them to MongoDB, emits an event (event emitter emits contractCreated), pushes jobs into a queue, and triggers browser RPA (UiPath or Power Automate or repurposed Playwright/Selenium) to complete contract steps. Implementation uses modules, controllers/services, DTOs, a MongoDB change stream listener, cron jobs (example: every 30s backup, daily 2am report), optional Redis/Kafka microservice for job history, and it runs end to end.
