Published on April 5, 2022, the Jamstack has evolved beyond its initial meaning of JavaScript, APIs, and pre-rendered Markup, focusing on building for the web without server-side rendering. The approach now allows for defining URLs that should be pre-rendered in the build process and generating the rest lazily when requested. Netlify's On-demand Builders are serverless functions used to generate web content as needed, automatically cached on Netlify's Edge CDN. This technology enables the creation of a site with an unlimited number of pages depending on URL parameters, such as Goofy Postcard, which uses Contentful as its platform powering the unlimited numbers of generated and cached HTML pages. The project demonstrates how to set up a site that renders content on the fly for faster builds using Jamstack principles and Netlify's On-demand Builders.
