Understanding Jamstack Architecture

What Jamstack actually means

Jamstack stands for JavaScript, APIs, and Markup. But it's less about specific technologies and more about an architectural approach: pre-render as much as possible, and use APIs for dynamic functionality.

Instead of a server generating pages on every request, Jamstack sites are pre-built into static files and served from a CDN. Dynamic features (forms, authentication, payments) are handled by APIs and serverless functions.

How it works

Build time

A static site generator (Gatsby, Next.js, Hugo) pulls content from your CMS, processes it, and generates optimised HTML, CSS, and JavaScript files. These files are deployed to a CDN.

Request time

When a user visits your site, they receive pre-built files directly from a CDN edge server near them. No database queries. No server processing. Just fast, cached content delivery.

Dynamic functionality

Need a contact form? A serverless function handles the submission. Need user authentication? A third-party service like Auth0 handles it. Need search? Algolia provides an API. Each dynamic feature is handled by the best tool for that specific job.

The benefits

Performance

Pages served from a CDN are fast. Very fast. There's no server-side processing delay, no database query time. The content is already built and waiting.

Security

With no server or database directly exposed to the public, the attack surface is dramatically reduced. There's no WordPress admin to brute force, no SQL database to inject into.

Scalability

CDNs are designed to handle traffic at scale. Whether you get 100 visitors or 100,000, the infrastructure handles it identically. There's no server to overwhelm.

Developer experience

Modern Jamstack tools provide excellent developer experiences. Hot reloading, component-based development, Git-based workflows, and automated deployments make development efficient and enjoyable.

Cost

Hosting static files on a CDN is cheap. Many sites can be hosted for free or near-free on platforms like Cloudflare Pages, Netlify, or Vercel.

When Jamstack makes sense

• Content-driven websites (marketing sites, blogs, portfolios)
• eCommerce storefronts (with a headless commerce backend)
• Documentation sites
• Landing pages and microsites
• Corporate websites

When to consider alternatives

• Real-time applications (chat, live dashboards)
• Very large sites with millions of pages (build times can be an issue)
• Applications requiring complex server-side logic on every request

Our Jamstack experience

At CodeDrips, Jamstack is a core part of our technology stack. We build primarily with Gatsby and Next.js, paired with headless CMS platforms like Sanity and Contentful. This combination gives our clients fast, secure, scalable websites with excellent content management experiences.
