In this blog post, we’ll walk through the process of building serverless applications using the power of WebAssembly with Fermyon Spin and htmx . For demonstration purposes, we will build a simple shopping list. We’ll implement the serverless back end in Rust. For building the front end, we’ll start with a simple HTML page, which we will enhance using htmx. Before we dive into implementing the sample application, we will ensure that everybody is on track and quickly recap what Fermyon Spin and htmx actually are. What is htmx? htmx is a lightweight JavaScript library built for developers, facilitating progressive enhancements in web applications. By seamlessly updating specific parts of a web page without necessitating a complete reload, htmx empowers us to effortlessly create dynamic and interactive user experiences. Its simplicity and performance-oriented approach, utilizing HTML attributes for defining behavior, make it a valuable tool for augmenting existing projects or crafting new front ends.…
