👋Hey, I need you to generate a complete backend project using Node.js with Express for a mobile marketplace app.
Here's everything the project should include and how it should work:
📌 General Stack:
Node.js with Express
PostgreSQL via Prisma ORM
JWT authentication for secure user sessions
BCrypt for password hashing
CORS
Helmet for securing HTTP headers
Multer for handling image uploads (store images locally in uploads/ folder for now)
Firebase Admin SDK for push notifications
Twilio Conversations API integration for in-app messaging
REST API, JSON-based communication
📌 Features to Implement:
📂 User Management
Sign Up / Sign In with:
Email & password
Google account (OAuth2)
Apple account (OAuth2)
Password recovery via email (send a reset link or code)
JWT-based Auth
Profile management API:
Photo, name, location, phone, WhatsApp number
View "my listings"
View "my favorites"
Edit profile info
Logout
Delete account
📂 Item Listings
Create Listing API:
Upload photos (support multiple)
Title, description
Price, category (fetched from DB)
Location
Allow phone or WhatsApp visibility
Get Listings (paginated, latest first)
Listing Detail
Mark item as Sold / Available
Bookmark (Favorite) listing
Report listing (send report info to admin DB table)
📂 Search and Filters
Search items by keyword (full-text search)
Filter items:
By category
By location (Mexico city zones — predefined list)
By price range
📂 Chat (with Twilio)
Integrate Twilio Conversations API
API to get conversation list per user
API to start a new chat (buyer <-> seller)
Setup Webhooks to listen to new messages from Twilio
On new message, trigger push notification via Firebase Cloud Messaging (FCM)
📂 Push Notifications
Integrate Firebase Admin SDK
API to send a push to a specific device
API to send mass notification (for admin)
📌 Other Requirements:
.env support for secrets (JWT_SECRET, DATABASE_URL, TWILIO, FIREBASE, etc.)
Swagger/OpenAPI docs for all endpoints (accessible via /docs)
Use Express middlewares for:
Error handling
Auth guard middleware (protect private routes)
Folder structure should be clean:
bash
Копіювати
Редагувати
/src
/controllers
/routes
/middlewares
/prisma
/services
/utils
/uploads
/prisma/schema.prisma
app.js
📌 Deliverables:
Complete, clean, ready-to-run Node.js backend project
Include package.json with all dependencies
Prisma migration and seed data for categories and dummy users
Instructions for:
Running locally (with npm run dev)
Setting up environment variables
Deploying to production
Please generate this project structure and code now.
I'll create a complete Node.js backend project for your mobile marketplace app with all the features you've requested. This will be a comprehensive, production-ready backend with proper structure and documentation.
