Expo Router API routes give React Native teams a practical middle ground between "everything is client-side" and "we need a separate backend project before we can ship." With EAS Hosting, those routes can be deployed alongside an Expo Router web app and used for server-side work such as secrets, validation, webhooks, AI calls, and small backend endpoints.

React Native teams now have two practical ways to add serious AI features to a mobile app:

• call Gemini models through Firebase AI Logic from a Firebase-aware app;
• keep AI orchestration on your own backend and call OpenAI from the server.

Both approaches can be correct. The wrong choice is usually the one that ignores secrets, user identity, App Store release cycles, cost controls, and how quickly your AI product will evolve.

Subscriptions look simple in product mockups: show plans, take payment, unlock premium features. In a real React Native app, subscriptions touch StoreKit, Google Play Billing, receipt validation, renewals, refunds, grace periods, intro offers, backend entitlements, app review, and customer support.

According to the official LiteLLM docs, LiteLLM can act as a Python SDK or as a proxy server that exposes 100+ models through an OpenAI-compatible format. The same docs highlight routing and fallbacks, spend tracking, budgets, virtual keys, logging, and rate limiting. That is exactly why tools like LiteLLM are showing up in more production stacks for AI chat, search, recommendations, and assistant features.

For React Native teams, that also means an AI gateway is no longer just backend plumbing. It is part of your release architecture. If the gateway is exposed, misconfigured, or compromised, your app can leak provider access, burn through budget, or break a core feature without a new binary release ever going through the App Store or Play Store.

This stretch has been one of the busiest periods the React Native ecosystem has seen in years. The important changes are not limited to framework releases. They also affect build pipelines, performance tooling, Expo workflows, and the platform requirements that determine whether your app can ship at all.

If you are building or maintaining a production app, these are the updates worth tracking first.

React Native templates are no longer just time-saving shortcuts. For serious teams, they are a strategic decision that affects architecture quality, release velocity, and long-term maintenance.

The problem is not finding templates. The problem is picking the right abstraction level for your product stage, then customizing it without destroying the advantages that made templates attractive in the first place.

This guide is written for developers and technical founders who want a clear, honest framework for choosing between free starters, premium kits, and production-ready full app templates.

It also covers the operational reality after you pick one: project planning, backend integration, UI patterns, performance tuning, testing, release, and scaling a portfolio of apps.

If you are evaluating options, start by scanning the current React Native templates collection and come back to this guide with your shortlist.

React Native architecture has moved from a bridge-centered mental model toward a typed, concurrent, multi-platform runtime. That shift affects how teams pick dependencies, write native modules, debug apps, design data flows, and decide when to use Expo, custom native code, or shared cross-platform packages.

Implement Android MVVM with unidirectional state, lifecycle-aware ViewModels, immutable UI models, coroutines, and repositories that expose clear contracts. This revised guide emphasizes supported APIs, production tradeoffs, and an upgrade-friendly path without tying the advice to a calendar year.

In this tutorial, we will explore various design patterns that can be used to architect your Angular application. Design patterns are reusable solutions to common problems that developers face during software development. By using design patterns, we can create more maintainable, scalable, and modular code. We will cover the MVC, Singleton, Dependency Injection, Observer, Facade, and Factory design patterns in the context of Angular development.

In this article we are going to learn how to implement the powerful MVVM design pattern in SwiftUI applications that are leveraging the Combine framework. The combination of these 3 concepts will be the standard of iOS app architecture for the years to come, so it’s really important to set up a solid groundwork when it comes to designing Swift apps going forward.

Writing highly-modularized code is critical in building a robust iOS app, that is scalable and extensible. To make a well-architected iOS app in Swift, there are various design patterns that can be used, to build a high-quality codebase. We focus a lot on building robust architecture in our Xcode app templates, so in this article we are sharing the way we leverage protocol-oriented programming in Swift, to create scalable iOS apps. We are not creating just one app, but instead, we are making a ton of app templates, so a good design is critical to our mission.

In this article we will talk about @EnvironmentObject in SwiftUI and how to use it to handle certain state management situations within our iOS applications.
