The lazy UI framework. Get lazui ... do less ... deliver more.
lazui is pronounced "lazy", as in "Lazy loading ... ".
lazui is a JavaScript library that allows you to create interactive websites and single page apps with less work.
lazui extends the attribute space of typical HTML to provide a rich set of functionality. It provides the JavaScript, so
you don't have to.
lazui gives you access to the best ideas from htmx, lighterHTML, Knockout, Turbo and Stimulus and Vue
lazui has a small core (less than 8K) and incremental loading of just the parts you use. Or, you can create a custom bundle for one time loading.
There are great features in the above libraries, you should not have to choose just one approach.
