Foodly food delivery app based on react native boasts a dynamic backend crafted with Node.js and Express, providing a solid foundation for high-performance operations. MongoDB is employed for efficient data handling, and Firebase Admin is seamlessly integrated to enhance backend management capabilities.
The frontend, developed with the latest version of React Native and Expo, features a sleek, cutting-edge user interface. Google Maps APIs are deftly incorporated for location-based services such as routes, directions, and geocoding, ensuring precise localization of users and restaurants. This geolocation accuracy allows for personalized recommendations and accurate delivery pricing. Additionally, the Distance Matrix is utilized to accurately calculate delivery costs, distances, and time estimates, ensuring a smooth and efficient user experience in our food delivery app.
Basic App Features
Backend System Overview
1. Authentication and Authorization
Integration with Firebase Admin: Implement backend services using Firebase Admin SDK to manage users, roles, and permissions.
Role-Based Authentication: Define four distinct roles: Admin, Vendor, Client, and Driver.
Advanced Middleware: Create middleware functions to verify user roles and enforce access control for protected routes.
2. User Management
Registration and Profiles: Enable registration for different user roles, each with a unique set of data fields and validation rules.
Implement JSON Web Tokens (JWT) for secure, token-based user authentication.
Use password encryption techniques (such as bcrypt) to ensure the safety of user credentials.
User CRUD Operations: Allow for adding, updating, and retrieving user information.
Address Management: Provide functionality for users to add, update, and retrieve addresses.
Implement logic to maintain a single default address per user, with the ability to change the default setting.
3. Vendor-Specific Features
Vendor Registration: Set up a registration process for vendors, including the collection of necessary information and validation.
Vendor Middleware: Ensure that only vendors can access routes for managing their restaurant and food items.
Food Management: Develop endpoints for vendors to upload and manage their food items.
4. Recommendations and Dynamic Content
Location-Based Restaurant Recommendations: Create endpoints that suggest restaurants to clients based on their current location.
Dynamic Food Recommendations: Develop algorithms to recommend food items to users also based on user location.
Preparation and Delivery Time: Introduce logic to recommend food that can be prepared and delivered in the shortest possible time, considering user location.
5. Shopping Cart and Order Processing
Cart Management: Allow users to add and remove items from the cart.
Enable users to adjust the quantity of cart items.
Update and return the cart count whenever changes are made to the cart.
Order Creation and Management: Provide functionality for users to create orders and customize them with add-ons.
Update orders based on payment and delivery status.
6. Categories and Recommendations
Category Management: Allow admins to add, update, and delete categories of food.
Category Recommendations: Use aggregation pipelines to offer random category recommendations to users.
7. Driver-Specific Functionality
Driver Registration and Restrictions: Establish registration for drivers and ensure middleware restricts them to driver-related tasks.

Run the app quickly
Here I will show you how to run the app without much effort once you get the source code. Watch the video and do as follow.
Run the application with food schema. Learn step by step how to create a schema and make it up and running.
Connect with firebase
Google map and api
Here we will see how to connect to our own google map and use our own api key.
Upload schema to your own mongodb
Here we will see how to upload the schema to our own mongodb. Watch the video and make sure you have already created a schema. Here we just show how to upload a given schema to your own mongodb.
Set up database name correctly
Once data has been uploaded make sure you have set the database name in the connection string.
Running both frontend and backend
Here once you uploaded your schema to mongodb, now you can run your own code locally. Make sure you set up the database name in the string.
Enable food search
Here we will see how to enable food search. To do that follow the video.
