📝 Walkthrough

Walkthrough

This PR updates an Astro project configuration to use the new top-level fonts structure, bumps core dependencies and integrations to latest major versions, reorganizes content collection setup into a dedicated file, adds HTTP redirect resolution for episode images, and updates transcript rendering to use the new content API pattern.

Changes

Cohort / File(s)	Summary
Configuration & Dependencies astro.config.mjs, package.json	Migrated font setup from experimental.fonts to top-level fonts with fontProviders.google(), added formats: ['woff2'], and bumped Astro to v6.0.3, @astrojs/preact to v5.0.0, and @astrojs/vercel to v10.0.0.
Content Collection src/content.config.ts, src/content/config.ts	Relocated transcripts collection definition from src/content/config.ts to new src/content.config.ts file with glob loader for *.md and *.mdx files.
Episode Image Optimization src/lib/optimize-episode-image.ts	Added new resolveRedirects() helper to follow HTTP 3xx redirects by extracting Location header, integrated into optimizeImage() for resolved image URLs.
Page Components src/pages/[episode].astro, src/pages/[episode].html.md.ts	Updated transcript rendering to call render(Transcript) instead of Transcript.render() and tightened body check from if (transcript) to if (transcript?.body).

Poem

🐰 The config takes flight to a brighter new nest,
With fonts at the top and redirects that jest,
Collections reorganized, episodes rendered with grace,
Each hop brings new order to this bustling place!

23-40: ⚠️ Potential issue | 🟡 Minor

Consider updating to latest patch versions for Astro 6.

All specified package versions exist and are compatible with Astro 6. However, newer patch versions are available:

• astro: 6.0.3 → 6.0.8 (latest)
• @astrojs/preact: 5.0.0 → 5.0.2
• @astrojs/vercel: 10.0.0 → 10.0.2
• @astrojs/db: 0.20.0 → 0.20.1

Update these to get bug fixes and improvements. Your Node 22.0.0+ requirement aligns with Astro 6's dropping of Node 18/20 support.

1-7: Consider using HEAD request for redirect resolution.

The current implementation uses GET which downloads the full response body just to check for redirects. A HEAD request would be more efficient since you only need the headers:

♻️ Proposed optimization

 export async function resolveRedirects(url: string): Promise<string> {
-  const response = await fetch(url, { method: 'GET', redirect: 'manual' });
+  const response = await fetch(url, { method: 'HEAD', redirect: 'manual' });
   if (response.status >= 300 && response.status < 400) {
     return response.headers.get('location') ?? url;
   }
   return url;
 }

Additionally, be aware of these edge cases:

1. Relative Location headers: Some servers return relative paths (e.g., /new/path). The code returns these as-is, which may break if an absolute URL is expected downstream.
2. Redirect chains: This only follows one hop. Multiple redirects (301 → 302 → 200) will return the first intermediate URL, not the final destination.

to GET if the server rejects HEAD) with redirect: 'manual', loop to follow
redirect chains up to a safe maxRedirects (e.g., 5) until a non-3xx status is
returned, and when reading response.headers.get('location') resolve any relative
Location values to absolute URLs using the original/current URL as the base (via
the URL constructor) before continuing the loop or returning the final URL;
update references to resolveRedirects to rely on this behavior.
