PDF Tools avoids complex long-polling architectures by utilizing a Serverless-Optimized State Machine.
- The Request: A user drops PDF files into the UI. The frontend uploads these files and initiates a processing job.
- State Tracking: The API records the job in MongoDB (e.g.,
uploading->processing). - Synchronous Processing: To comply with Vercel's serverless architecture, the PDF operation runs synchronously inside the API route, preventing dangling promises from being frozen by the platform.
- Completion: The database state transitions to
completedand the user instantly receives their manipulated document.
