Hyvä-Compatible Magento 2 Modules That Actually Improve Core Web Vitals

Hyvä delivers a lean, performance-first frontend for Magento 2 but Core Web Vitals (CWV) still depend on how extensions handle assets, images, and rendering. Many so-called “Hyvä-compatible” modules reintroduce frontend bloat or conflicts. In this article, we highlight qoliber extensions that are truly Hyvä-safe and engineered to improve CWV metrics like LCP, CLS, and TBT.

1. Lazy Loading for Better LCP

Largest Contentful Paint (LCP) often suffers when product listing and detail pages load too many images upfront. Hyvä makes it easy to apply native loading="lazy", but modules that inject galleries or banners can still block rendering. qoliber performance modules enforce lazy load for secondary assets while keeping above-the-fold media eagerly loaded, balancing UX and performance.

2. Image Optimization & WebP Support

Oversized images are a top cause of poor CWV scores. qoliber SEO extensions include functionality to generate SEO-friendly file names, alt attributes, and serve optimized formats like WebP. Clean markup plus optimized image delivery reduce transfer size, boosting LCP and improving crawlability.

3. Deferring Non-Critical JS

Even in Hyvä, some modules attempt to push inline scripts or load third-party JS globally. That increases Total Blocking Time (TBT). qoliber performance-safe modules defer non-critical JS execution until after interaction readiness, ensuring first input delay (FID) stays low and CWV audits stay green.

4. Clean CSS Output and No Legacy Assets

Many “compatible” extensions still inject RequireJS, Knockout, or heavy CSS bundles. Hyvä’s philosophy removes them, and qoliber extensions respect this. CSS is scoped, minimal, and Tailwind-compatible, so modules never cause layout shifts (CLS) or unexpected reflows on PLPs or PDPs.

5. SEO & Structured Data Without JS Injection

Structured data (breadcrumbs, product schema, Open Graph) should render server-side, not injected with JS after page load. qoliber SEO modules follow this rule: clean JSON-LD inlined in HTML ensures Google parses it instantly, without hurting CWV or delaying paint times.

6. Sitemaps & Canonicals That Reduce Crawl Load

Search engine crawlers hitting thousands of unnecessary URLs can slow down server response. qoliber’s SEO: Advanced Sitemaps and SEO: Pretty Filter URLs modules reduce crawl waste and keep server load predictable. Lower backend stress means faster TTFB for real users - another CWV factor.

Conclusion

Core Web Vitals can’t be gamed with marketing claims - they require technical discipline and performance-first code. Hyvä gives Magento 2 projects the right baseline, but only extensions built with the same philosophy make the difference.

At qoliber, every module we ship is Hyvä-compatible, ElasticSuite-ready, and CWV-safe. From lazy load and WebP to structured data and sitemap control, our Magento 2 extensions are engineered to actually improve CWV scores in real audits --> not just demos.
