# Jamstack

> Jamstack is a modern web architecture in which the presentation layer is pre-rendered and served from a CDN, while JavaScript and APIs provide the dynamic parts.

**Jamstack** is a modern architecture for building websites and web applications in which the presentation layer is generated in advance and served as ready-made files, while interactivity comes from JavaScript and external APIs. The name derives from three pillars: **J**avaScript, **A**PIs and **M**arkup. Unlike traditional systems that assemble a page on the server for every request, Jamstack decouples the frontend from the backend and publishes it as static assets.

## What Jamstack involves

The foundation is pre-rendering: a static site generator builds ready HTML files at deployment time rather than at the moment of the visit. It works in a few steps:

1. content is pulled from sources — files or headless CMS systems;
2. the generator assembles static pages from it during the build process;
3. the files are pushed to a [CDN](https://nodea.io/en/glossary/cdn) and served from the edge closest to the user;
4. dynamic features are handled by [JavaScript](https://nodea.io/en/glossary/javascript) calling external [APIs](https://nodea.io/en/glossary/api).

The result is very fast loading, a smaller attack surface (no database on the front end) and easy scalability, since serving files from a CDN is cheap and efficient.

## Practical applications

Jamstack works well for blogs, documentation, company sites, portfolios and shops in the [headless commerce](https://nodea.io/en/glossary/headless-ecommerce) model. Popular tools include Next.js, Nuxt, Astro and Hugo, and dynamic operations are often handled by [serverless](https://nodea.io/en/glossary/serverless-computing) functions. The approach fits best where content changes periodically and the priorities are speed, security and low maintenance cost. One limitation can be the build process: for very large sites, generating thousands of pages can take a long time, which is why incremental rendering techniques are used to update only the changed pages. Jamstack is also not ideal for applications with intense, immediate server-side interactivity, where content must be assembled individually for each user on every request. Even so, for a large share of typical sites it is an attractive alternative to classic content management systems, shifting the workload from the server to the build step and the content delivery network.

### Is Jamstack suitable for an online store?

Yes, in a headless model. The commerce layer (cart, payments, inventory) runs as a separate service exposed through an API, while the storefront is generated with Jamstack architecture. This combines the speed of a static site with full e-commerce functionality.
