React 18 is Meta’s latest iteration of its popular JavaScript library for building user interfaces.

Whether you’re a seasoned developer or a coding newbie, React 18 provides the tools you need to create fast, scalable, and interactive web applications — like a food delivery platform similar to Swiggy.

React 18 offers better performance, scalability, and developer experience, making it the perfect choice for modern web apps.

🚀 Why Choose React 18 for Your Food Delivery App

Before diving into development, let’s understand why React 18 is your best bet for building a Swiggy-style food delivery app:

  • Speed and Performance: React’s virtual DOM and concurrent features drastically reduce load times.
  • Component Reusability: Break your app into reusable components like Header, MenuItem, or Cart.
  • Scalability: React apps scale well, from MVPs to enterprise-level solutions.
  • Community and Ecosystem: Access thousands of libraries, tools, and open-source resources.
  • Developer Tools: React DevTools make debugging and performance tracking a breeze.

The keyword “React 18” is not just relevant here — it’s essential. It’s the engine driving your app from concept to completion.

A Swiggy-style app combines various features to enhance usability, engagement, and transactions. Here are the core functionalities we aim to replicate:

  • User Authentication
  • Restaurant Listings
  • Search and Filter
  • Menu Display
  • Add to Cart and Checkout
  • Order Tracking
  • Ratings and Reviews
  • Mobile Responsiveness

To bring these features to life, we’ll use React 18’s strengths along with some auxiliary tools like react-router-dom, axios, and json-server.

Initial deployment can be free using Vercel or Netlify; scaling may require a paid backend service.

6. Do I need TypeScript for this project?

Not mandatory, but TypeScript adds type safety and is highly recommended for large projects.
