How does barcode scanning work?

The mobile app uses the device camera to scan a barcode. The UPC is queried against the Open Food Facts or Nutritionix database. If the product is found, its nutritional data pre-fills the food log entry. For unlisted items, users can manually enter and save to their custom food library.

How does the dietitian portal work?

Dietitians log in to see their client list with each client's daily food diary, macro adherence, weight trend, and upcoming check-ins. They can assign meal plans, send messages, and add clinical notes per client. Clients see the assigned plan in their app.

How is calorie burn integrated?

Users connect Apple Health or Google Fit via OAuth. The app reads daily step count and active calories from the connected source. Net calorie balance = food calories − calories burned. Fitness data syncs each time the app opens.

The Challenge

Why building a Nutrition Tracker from scratch is hard

Building a Nutrition Tracking & Meal Planning Platform from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing nutrition tracker-specific business logic, integrations, and role-based access rules.

What's Included

Everything your Nutrition Tracker needs

ProjectCode generates a production-ready Nutrition Tracker with all the modules your team needs from day one.

Food diary with macro and micronutrient tracking

Barcode scanner for packaged food lookup

Meal plan generator based on goals and dietary restrictions

Recipe builder with nutritional calculation

Water intake tracking

Integration with fitness trackers for calorie burn data

Dietitian portal for client plan assignment

Progress tracking: weight, measurements, and goal metrics

Architecture

How it's built

The generated Nutrition Tracker follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for nutrition tracker workflows

NestJS REST API with dedicated nutrition tracker modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all nutrition tracker entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live nutrition tracker status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

Database

PostgreSQL schema designed for Nutrition Tracker

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

meal_plans (id, user_id, dietitian_id, name, days jsonb, total_calories, created_at)

FAQ

Common questions about building a Nutrition Tracker

The platform uses the USDA FoodData Central database (free, open API) with 1M+ foods including branded items, raw ingredients, and restaurant items. Each item has per-100g nutritional values. The food log calculates nutrition based on the entered serving size.
