React Native is a JavaScript-based mobile-app framework created by Meta (Facebook) that allows developers to build fully native mobile applications for both Android and iOS using a single codebase.
Instead of writing separate apps in Java or Swift, teams can reuse up to 90 % of their code — reducing development time and cost while maintaining native performance.

What We Teach at Oliya.tech

At Oliya Academy, React Native is taught as the mobile counterpart to the React web curriculum.
From Week 3 onward, students move from the browser to the device, using the same component-driven mindset they mastered earlier.
Each learner builds, tests, and deploys a production-grade mobile application connected to a live Django REST API.

The learning journey includes:

• Setting up development environments using Expo CLI and React Native CLI.

• Understanding the component hierarchy (View, Text, ScrollView, FlatList).

• Managing state through useState, useReducer, and Context API.

• Navigation patterns with React Navigation v6 (Stack, Drawer, Tabs).

• Integrating Axios for API calls to live back-ends.

• Handling authentication flows, JWT tokens, and session persistence via AsyncStorage.

• Using native device features — Camera, Location, Push Notifications, and Maps.

• Integrating payment gateways (Stripe / Razorpay SDKs).

• Testing with Jest, performance profiling using Flipper, and publishing builds via Expo EAS.

• Deployment pipelines on AWS Amplify or Google Play Console, with CI/CD setup through GitHub Actions.

By the end of the cycle, every student has published a fully functioning app that mirrors a commercial mobile product.

Industry Examples

All examples below are publicly confirmed through engineering blogs, conference talks, or open-source repositories.

1. Meta (Facebook & Instagram)
React Native was developed by Facebook’s engineering team and is used inside Facebook Ads Manager, Instagram, and portions of the Facebook main app.
Meta engineers maintain React Native as an active open-source project with continuous optimisation for iOS and Android.

2. Airbnb
Airbnb publicly shared its adoption of React Native for cross-platform features in its mobile app.
Although later it restructured its architecture, the company credits React Native for rapid experimentation and early mobile velocity.

3. Uber Eats
Uber’s mobile division uses React Native to deliver a uniform customer experience for its food-delivery app.
Engineers have confirmed its use in restaurant dashboards and order-tracking components.

4. Walmart
Walmart migrated large portions of its shopping app to React Native to unify Android and iOS development.
The Walmart Labs blog cites significant reductions in code duplication and release cycles.

5. Bloomberg
Bloomberg’s mobile engineers publicly confirmed that the Bloomberg consumer app is built with React Native, allowing instant updates and real-time market data refreshes across devices.

6. Shopify
Shopify adopted React Native company-wide, rebuilding its merchant mobile apps and its Point-of-Sale (POS) product on the framework.
Shopify engineers also contribute to the React Native core and publish documentation on best practices.

7. Tesla
The Tesla Mobile App — used for controlling vehicles and monitoring energy products — employs React Native for cross-platform UI, confirmed by developers involved in its early builds.

8. Discord
Discord’s iOS and Android apps use React Native for messaging, audio controls, and interface consistency.
Engineering blogs show how React Native’s virtual DOM keeps high-frequency chat rendering performant.

9. Delivery Hero / Swiggy / Zomato
Food-delivery platforms in multiple markets, including Swiggy and Zomato in India, rely on React Native for customer and vendor mobile apps.
This choice enables fast iteration and synchronised feature updates across operating systems.

10. Coinbase Wallet
Coinbase’s mobile wallet leverages React Native to manage crypto-asset dashboards and user authentication flows, as described in official developer interviews.

Summary

Across these verified implementations, React Native has proven to be the dominant framework for cross-platform mobile development.
It is trusted by global enterprises for three main reasons:

1. Single Codebase Efficiency — shared logic for Android and iOS reduces delivery time.

2. Native Performance — direct access to platform APIs ensures speed comparable to native apps.

3. Scalability — its modular design scales easily from startups to billion-user ecosystems like Facebook and Instagram.

React Native bridges the web and mobile worlds, allowing developers to reuse React knowledge while delivering genuine native experiences.
