SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Astro developers often struggle to choose and configure rendering modes (SSR vs SSG) and middleware for protected content; this skill provides patterns and gotchas to implement robust rendering pipelines.

Core Features & Use Cases

  • Rendering mode guidance: Decide between SSR and SSG for pages, routes, and API endpoints with practical examples.
  • Middleware patterns: Implement route protection and status checks across content collections.
  • Project troubleshooting: Debug common rendering issues and TypeScript gotchas in Astro projects.

Quick Start

Configure an Astro page to render with middleware in both SSR and SSG modes to validate access control.

FAQPage Schema
How do I choose between SSR and SSG rendering modes in Astro?

Astro rendering mode choice depends on content needs: SSG pre-renders pages at build time for static content, while SSR dynamically renders pages on the server for protected or real-time data. This skill helps you reason about the correct mode for pages and API routes.

How do I implement middleware for route protection in an Astro project?

Astro middleware intercepts requests to implement route protection and status checks across content collections. This skill provides patterns to configure middleware for access control in both SSR and SSG modes.

Can I use authentication with static output in Astro 5.x?

Yes, Astro 5.x supports authentication with static output by using middleware to validate access control during prerendering. This skill guides you through configuring protected content in SSG mode.

What is the best way to debug TypeScript gotchas in Astro rendering pipelines?

Debugging TypeScript gotchas in Astro rendering pipelines requires reasoning about SSR/SSG configurations and API routes. This skill helps troubleshoot common rendering issues and type errors in Astro projects.

Why does my Astro prerendered page bypass middleware authentication checks?

Astro prerendered pages bypass runtime middleware because they are generated at build time. This skill explains how to apply middleware patterns correctly to ensure access control works across SSG and SSR modes.
