Docusaurus
Docusaurus — static site generator for fast, secure, and scalable websites.
Stack Components
Why
Pre-renders HTML at build time for optimal performance and zero server runtime. Static site generators (Astro, Eleventy) produce 3-10x faster pages than SSR frameworks.
Astro's island architecture ships 90% less JavaScript than Next.js by default, scoring 95+ on Lighthouse.
When
Use for docs, blogs, and marketing sites. Avoid for dynamic user-specific content (use SSR).
How
Example
Common Problems
- ⚠Docusaurus rebuild slow for large sites — use incremental builds
- ⚠No dynamic content — add client-side JS or edge functions if needed
- ⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical
Best Practices
- ✓Deploy Docusaurus output to CDN for global edge caching
- ✓Use {ne} content collections for type-safe frontmatter
- ✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit
FAQ
What is Docusaurus and what projects is it for?
Docusaurus — static site generator for fast, secure, and scalable websites. It pairs layered technologies for end-to-end type safety and out-of-the-box deploys, fitting everything from MVPs to production SaaS.
How do I spin up a working demo with Docusaurus in 10 minutes?
Two steps: (1) Install Docusaurus; (2) Write content (MD/MDX). Get the local dev server running, then wire one real data source to verify the end-to-end loop.
What is the most common pitfall with Docusaurus and how do I avoid it?
The most common pitfall is: Docusaurus rebuild slow for large sites — use incremental builds. Avoid it by adding the matching checklist to your PR template and running type-check + lint + unit tests in CI — three gates before merge.
What are the best practices for Docusaurus?
Best practices for Docusaurus include: Deploy Docusaurus output to CDN for global edge caching; Use {ne} content collections for type-safe frontmatter; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Deploy Docusaurus output to CDN for global edge caching" — should be set up at project init to avoid costly rework later.
When should I NOT choose Docusaurus?
Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). Docusaurus shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
