Vianoce v Bratislave off Wix, onto Astro. A cultural archive the team can actually update.
Vianoce v Bratislave is a festive Christmas concert with a history going back to 2010. The old Wix site worked as an online poster, but it was hard for the client to edit, the mobile layout was fragile, and past-edition content was scattered across galleries, old slugs, and Wix sections. The new Astro site turns it into a fast cultural archive: the upcoming 17th edition, history, photo galleries, videos, partners, redirects, and content structured for future years.
From a single Wix poster to a structured edition archive.
Rescue the content first. Then turn it into a system.
This was not just a visual refresh. The real value was taking apart the old concert site, inventorying editions, photos, programmes, partners, and videos, then rebuilding them into a structure the team can keep using for future concerts.
- Original Wix audit
Inventory pages, links, and assets
We captured the original desktop and mobile state: homepage, cast, About, partners, gallery, video gallery, and contact. The Wix homepage had 25 scripts and external hosts including static.parastorage.com, GTM, GA, and Sentry.
- Content migration
Editions instead of one-off sections
We normalised the content into editions: 2010 to 2019, 2022 to 2026, including cast, programmes, photo galleries, videos, partners, and redirects from the old Wix URLs.
- New build
Astro site with concert atmosphere
The new design uses a dark opera-house visual direction, real concert photography, self-hosted logos and assets, static pages with no runtime scripts on the homepage, and structured data for concert editions.
- Handover
Preview ready for approval
The new state is deployed to a noindex preview domain. Production cutover can happen after photo, video, and partner-logo rights are confirmed.
Less Wix runtime. More content.
Mobile and desktop Lighthouse runs comparing the original Wix site and the new Astro preview. The new site carries a richer visual system and a much larger archive, so it is not smaller in bytes, but it cuts Wix runtime weight and request count sharply. The preview SEO score is lower only because the preview intentionally remains noindex.
Mobile lab data: Performance 74 → 81, Accessibility 91 → 100, Best Practices 100 → 100, SEO 100 → 69 because the preview is noindex. Desktop: Performance 69 → 87, LCP 7.6 s → 2.2 s, requests 146 → 40.
Not just a new look. A concert archive.
- Astro 6 static site with noindex preview on vianocevbratislave.alohasmile.sk.

- Preview remains noindex until photo, video, and partner-logo rights are signed off.
