Architecture

Stack

• Frontend: React + Vite (apps/web)
• API: Express + TypeScript (services/api)
• AI Service: FastAPI (services/ai)
• Data: MongoDB + Redis/BullMQ

Request flow:

Web -> /api/* (Express) -> /v1/* (FastAPI)

Async checklist jobs:

Express route -> BullMQ queue -> API worker -> AI pipeline -> MongoDB

Features

• Auth (register/login/me)
• Manual upload and management
• Checklist generation jobs with status tracking
• Checklist detail page with item updates
• PDF export for generated checklists
• Per-manual persisted chat history

Repository Structure

• apps/web: React frontend
• services/api: Express API + worker
• services/ai: FastAPI AI pipeline service
• docs: project documentation
• packages/shared-types: shared DTO package scaffold
