We want a web app to display a list of data and have an input field to interactively filter it. We’ll start with a simple, regular web app built with Hunchentoot. We’ll have a search input to filter our data, and we’ll see that to be more interactive, typically to filter out the results as the user types, we’ll need more than basic HTTP requests. We’ll need some JavaScript. But we’ll reach this level of interactivity with CLOG (and no JavaScript).
