Basecoat is a zero-runtime UI library and themable interface framework consisting of a set of accessible web components. It provides a collection of pre-styled interface elements and utility classes designed to function as static assets without requiring a dedicated JavaScript framework runtime.
The project features a dedicated UI component scaffolder, providing a command line interface to automate the generation of project folder structures and the installation of component templates. Visual styles are managed through a system of CSS variables and utility classes, allowing for global theme application and page theme toggling via custom events.
The library covers a broad surface of accessible interface elements, including comprehensive form inputs, layout containers, navigation patterns, and overlay components. These elements utilize ARIA standards and semantic HTML to ensure accessibility across inputs, modals, and navigation menus.
A command line utility is provided to automate the setup of these components by copying JavaScript and template macros directly into a project directory.
