Question 1

How does Astro compare to Next.js for static sites?

Accepted Answer

Astro typically delivers better performance for static sites by shipping minimal to zero JavaScript by default, while Next.js includes more client-side JS. However, Next.js has stronger built-in SSR and API routes for dynamic content.

Question 2

Can I use Astro for e-commerce sites?

Accepted Answer

Yes, but it's best for static product pages; for dynamic features like shopping carts, you'll need to manage client-side state carefully using island architecture, which can add complexity.

Question 3

How to add React components in Astro?

Accepted Answer

Install the @astrojs/react integration, then import and use React components in .astro files with client directives like `client:load` to control hydration based on your needs.

Question 4

Does Astro support server-side rendering (SSR)?

Accepted Answer

Yes, but it requires an adapter like @astrojs/node or @astrojs/vercel and configuration in astro.config.mjs. It's optimized for static generation, so SSR setup isn't as straightforward as in some other frameworks.

Question 5

What's the performance impact of using multiple UI frameworks in Astro?

Accepted Answer

Minimal impact on initial load since Astro compiles to static HTML, but bundle size can increase if many interactive components from different frameworks are hydrated, potentially affecting runtime performance.

Question 6

How to deploy an Astro site to Vercel?

Accepted Answer

Use the @astrojs/vercel adapter, add it to your astro.config.mjs, and deploy via Vercel's platform—the integration handles most setup automatically for static or SSR deployments.
