Astro

What Astro is

Astro is an open-source web framework, first released in 2021, designed for building content-rich websites, marketing sites, blogs, documentation and e-commerce fronts. Its defining idea is that most websites don’t need to ship a heavy JavaScript application to the browser. Astro renders your pages to plain HTML at build time and, by default, sends zero JavaScript to the visitor.

Where a page genuinely needs interactivity, Astro lets you add it as a self-contained “island”, a small component (built in React, Vue, Svelte or plain JavaScript) that loads on its own, while the rest of the page stays static and instant. You get the speed and SEO of a static site with the interactivity of a modern framework exactly where it earns its place.

How HDC uses Astro

Astro is our default for client websites, and it’s what this very site is built on. In practice that means:

• We build each page as static HTML that’s served pre-rendered, so it appears almost instantly even on a phone with a poor signal on a job site.
• We use Astro’s Content Collections to manage larger sites, services, locations, blog posts, case studies, in a structured, type-safe way, so a 60-page site stays as maintainable as a 6-page one.
• We add interactivity as islands only where it pays off: a lead form, an image slider, a quote calculator, live chat. Everything else ships no JavaScript.
• We pair Astro with Tailwind CSS for styling and host on Cloudflare Pages, where every page is cached at the edge, close to your customers.

Why we apply it

Two things win trades and local businesses more work online: being found (SEO) and not losing the visitor (speed and clarity). Astro is engineered for both. Google has found that 53% of mobile visitors abandon a page that takes more than three seconds to load; Astro pages routinely load in a fraction of that. And because the full content is in the HTML from the first byte, both Google and AI answer engines can read and rank the page properly.

For a business paying for ads, that matters twice over: a faster, better-ranking site means more of every click turns into an enquiry instead of a bounce.

How Astro fits our stack

Astro is the foundation we build on, not the whole picture. On a typical project it sits alongside Tailwind CSS for styling, React for the handful of interactive islands a site needs, TypeScript for safer code and typed content, Cloudflare for edge hosting and security, and a CMS or headless WordPress when a client needs to edit content themselves. That combination gives clients a site that’s fast, secure, easy to update and built to rank, without the bloat of a heavyweight app framework.

When Astro isn’t the right tool

We’re honest about fit. If a project is really a web application, a customer dashboard, a booking platform with constant interactivity, a SaaS product, a framework like Next.js or a dedicated app stack is the better choice, and we’ll build that instead. Astro shines for the content and marketing sites that need to load fast and rank well, which is exactly what most trades and local businesses need.
