Static Site Generation (SSG)
Static Site Generation (SSG) is a Rendering strategy where all HTML pages are pre-rendered at build time and served as static files. There is no server generating HTML on every request — the web server delivers finished files directly. The result: maximum performance, perfect PageSpeed scores, and a minimal attack surface.
Why SSG for content websites?
Static pages load faster than any server-rendered alternative: no database access, no template engine, no application server — just a web server delivering files. Combined with a CDN , SSG pages achieve load times under 100ms worldwide. For Indexierung by search engines, SSG is ideal: crawlers receive complete HTML immediately without JavaScript dependency.
SSG vs. SSR — when to use what?
Server-Side Rendering generates HTML on every request — ideal for personalized or frequently updated content. SSG generates HTML once at build time — perfect for pages whose content rarely changes: glossaries, blogs, portfolios, corporate websites. Hybrid approaches (Incremental Static Regeneration) update individual pages in the background without repeating the entire build.
SSG with Angular
Angular supports SSG natively since version 17. The Build-Prozess renders all defined routes to static HTML files that can be hosted on any web server (Apache, Nginx, CDN). JSON files as content sources enable a Headless CMS -like authoring experience without runtime database dependency. Critical CSS is automatically inlined.
Security advantages of SSG
Static pages have no application-level attack surface: no SQL injection, no XSS through server-side templates, no session hijacking risks. The entire attack surface is reduced to the web server and its configuration — which significantly simplifies Server Hardening . For projects with high security requirements, SSG is often the safest architectural decision.
How we use it
The btech-solutions.eu platform is a concrete SSG project: over 120 pages are generated from JSON files via Angular prerender and served as static HTML on Apache. Build time for all routes: under 90 seconds. Our CI/CD pipeline renders automatically on every push to main. For clients with regular content updates, we couple SSG with Webhook -based rebuilds — preserving the speed advantage without manual build effort.
