As Magento 2 continues to evolve, its legacy Luma and Blank themes are increasingly seen as outdated, heavy, and difficult to customize. This is why so many developers and store owners are embracing the Hyvä theme: a modern frontend built for speed, simplicity, and a far better developer experience.

Whether you're integrating Hyvä from scratch or migrating an existing Luma-based storefront, here are some practical, field-tested tips to help you ensure a smooth and successful transition.

1. Assess extension compatibility early

Hyvä removes Magento’s reliance on Knockout.js and jQuery, which means many traditional extensions won’t work out of the box.

Before writing a single line of code, evaluate all third-party modules you depend on.

✔️ Tip: Use the official Hyvä Compatibility Module Tracker to check whether your extensions already support Hyvä or if alternatives exist.

This step alone can save weeks of unnecessary development work.

2. Start with a clean Magento instance (If possible)

For the best results, start your integration on a fresh Magento 2 installation.

Avoid carrying over old Luma-based styles, overrides, or bloated customizations unless they’re absolutely essential. Hyvä is designed for performance, so a clean slate helps you take full advantage of its optimized architecture.

3. Leverage Tailwind CSS and Alpine.js

Hyvä’s frontend stack is intentionally lightweight, using:

Tailwind CSS for utility-first styling

Alpine.js for minimal, reactive behavior

Ensure your team is familiar with these technologies; they’ll enable faster development cycles, cleaner HTML, and less JavaScript debt.

4. Plan for design adjustments

Hyvä uses different layout structures, templates, and component patterns compared to Luma.

If you have existing Figma or UI design files that were created with Luma in mind, expect some level of adaptation.

A short UI/UX design alignment sprint can help ensure your visuals match Hyvä’s structure without compromising the intended design.

5. Optimize critical path CSS & fonts

Hyvä already minimizes render-blocking resources, but you can take performance even further by:

Fine-tuning critical CSS

Using optimized web fonts

Implementing smart lazy loading for images

Reducing unused CSS utilities (via Tailwind’s purge process)

These refinements can significantly boost your Core Web Vitals, especially Largest Contentful Paint (LCP) and First Input Delay (FID).

6. Choose the right checkout strategy

Hyvä provides a lightweight Hyvä Checkout solution, but you also have the option of keeping the original Luma checkout as a fallback.

Hyvä checkout → Faster, modern, and performance-optimized

Luma checkout → Still works, but may limit your full performance gains

⚠️ Note: If you keep the Luma checkout, your site won't achieve the maximum speed benefits Hyvä is capable of delivering.

7. Follow Hyvä best practices & leverage the community

The Hyvä ecosystem is incredibly active.

Join the Hyvä Slack community, keep up with documentation updates, and learn from the shared code snippets and best-practice discussions. This support network is invaluable during integration.

Final thoughts

Hyvä isn’t just a theme; it’s a performance revolution for Magento. When implemented thoughtfully, it can:

Dramatically improve site speed

Reduce frontend complexity

Boost developer productivity

Enhance the overall user experience

If you're planning a Hyvä integration or migration, following the best practices above will set you up for success.
