Discover the latest advancements in React frameworks with opt-in design principles. Learn how Astro, React Server Components, and SolidJS empower developers to build performant, user-friendly applications.

Key takeaways
  • Opt-in design is a new approach to framework development that emphasizes starting with the simplest possible solution and adding complexity only when necessary.
  • Astro is a framework that embraces opt-in design principles, allowing developers to choose which features they want to use and when.
  • React Server Components are a new feature that allows developers to opt-in to server-side rendering for specific components, without having to re-architect their entire application.
  • SolidJS is a framework that takes a different approach to reactivity than React, by using signals and effects to track changes and update the UI accordingly.
  • Opt-in design can help developers build more performant and user-friendly applications by avoiding unnecessary complexity and focusing on the user experience.
  • Some key principles of opt-in design include:
    • Starting with the lowest common denominator
    • Adding complexity with simple flags that describe what’s added
    • Staying user first with the API
  • Opt-in design is a powerful approach that can help developers build better applications. By embracing opt-in principles, developers can create applications that are performant, user-friendly, and easy to maintain.
