    Framevuerk

    Framevuerk

    Fast, Responsive, Multi Language, Both Direction Support

    Framevuerk is an archived Vue.js-based UI framework created for building fast, responsive, configurable web interfaces. It was designed without external dependencies beyond Vue and focuses on practical component-based application layouts. The framework supports both left-to-right and right-to-left interface directions, making it useful for multilingual products and internationalized user experiences. It also includes customization options for language, direction, colors, spacing, transitions, shadows, and other visual settings through a builder configuration. Developers can install it through npm and integrate it into a Vue app with its script and stylesheet. Although the repository is now read-only, it remains a useful reference for older Vue UI framework design and configurable front-end theming.
