Lunor is a domain-specific language that can be used in the early phases of front-end development by allowing developers to describe web interfaces in a clear, human-readable syntax that incorporates Markdown for defining the content of a web application. The proposed solution integrates three key components: the Lunor language definition, a template-based code generation, and a Visual Studio Code (VS Code) extension built on the Language Server Protocol, forming a comprehensive environment for efficient web development. Lunor enables rapid prototyping and the creation of simple, yet fully functional web applications, while the generated code remains compatible with standard web technologies for further expansion.
