Build, launch, and keep improving
Practical guides for building, customizing, launching, and growing software products.
Make Angular pages crawlable through server rendering or prerendering, stable URLs, complete metadata, structured data, and fast HTML responses. This revised guide emphasizes supported APIs, production tradeoffs, and an upgrade-friendly path without tying the advice to a calendar year.
Design Angular forms with typed reactive models, reusable validation, accessible errors, predictable submission state, and server-side validation. This revised guide emphasizes supported APIs, production tradeoffs, and an upgrade-friendly path without tying the advice to a calendar year.
Use RxJS for asynchronous streams and cancellation while using signals for local synchronous state where they make ownership clearer. This revised guide emphasizes supported APIs, production tradeoffs, and an upgrade-friendly path without tying the advice to a calendar year.
Compare Kotlin and Java for JVM and Android work through interoperability, null safety, concurrency, tooling, team adoption, and library constraints. This revised guide emphasizes supported APIs, production tradeoffs, and an upgrade-friendly path without tying the advice to a calendar year.
Learn Kotlin coroutines through structured concurrency, cancellation, dispatchers, lifecycle ownership, and testable suspend functions. This revised guide emphasizes supported APIs, production tradeoffs, and an upgrade-friendly path without tying the advice to a calendar year.
Use Kotlin Multiplatform to share domain and data logic while choosing shared or native UI based on product and team constraints. This revised guide emphasizes supported APIs, production tradeoffs, and an upgrade-friendly path without tying the advice to a calendar year.
Expose real product actions to the system instead of treating your app as an isolated screen stack.
App Intents are becoming one of the most important integration points for iOS apps. They let your app expose actions and data to system features such as Siri, Shortcuts, Spotlight, widgets, and other surfaces that can help users act without opening the full app first.
For SwiftUI templates, this is a major opportunity. A template usually already has a predictable product loop: browse products, start a chat, save a listing, log a workout, check an order, or create a reminder. App Intents turn those loops into system-level capabilities.
This guide explains how to plan App Intents in a SwiftUI app template:
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.
Flutter teams now have two strong Google-backed paths for AI features:
The right choice is less about which one is "better" and more about where the AI decision should live: in the Flutter client, in a backend flow, or across both.
React Native teams now have two practical ways to add serious AI features to a mobile app:
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.
Flutter apps are cross-platform, but privacy review is still native. Your
pubspec.yaml dependencies can pull in iOS pods, Android libraries, analytics
SDKs, crash reporters, payment SDKs, Firebase packages, and permission handlers
that affect App Store and Google Play disclosures.
Subscription screens are easy to mock in Flutter. Real subscription systems are not. A production app needs store products, test accounts, purchase listeners, receipt validation, renewals, cancellations, refunds, restore purchases, customer support, and a reliable entitlement model.
