The JAMstack is a website development approach that utilizes JavaScript, APIs, and Markup to build fast, secure, and simple websites. It involves hosting the frontend on a Content Delivery Network (CDN) and using APIs for dynamic functionality. In this tutorial, we'll be building a static website using Hugo on Netlify with continuous deployment from GitHub. The process starts by setting up a new Hugo project, installing dependencies, and initializing the repository. We then create our first page, "About," and add it to the theme's navigation. To deploy the site, we link it to our GitHub repository and configure settings for Netlify. After building and deploying the site, we can customize its appearance and set up a custom domain. The JAMstack approach allows developers to build fast, secure, and simple websites with minimal server-side overhead.
