Case study

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.

How we worked

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.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

PageSpeed Insights

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.

What ships

Not just a new look. A concert archive.

  • Astro 6 static site with noindex preview on vianocevbratislave.alohasmile.sk.
  • Homepage with no runtime scripts in the DOM inventory, compared with 25 scripts on the original Wix homepage.
  • 16-edition history with separate pages for each year and the 17th edition already prepared.
  • 304 historical photos plus new 2025 and 2026 photos, optimised into responsive variants.
  • Photo galleries with lightbox, YouTube videos, partner sections, and old Wix URLs redirected to the new routes.
  • JSON-LD for WebSite, WebPage, BreadcrumbList, and MusicEvent when an edition has a confirmed date.
  • Content split into Astro Content Collections so the next edition can be added as data, not as a layout rebuild.
  • Original state captured as a case-study inventory with desktop and mobile screenshots.
  • Preview remains noindex until photo, video, and partner-logo rights are signed off.
