A language server for the Web.
WEBlsp is an implementation of the Language Server Protocol (Work In Progress) providing full-featured language support for HTML and CSS, including code completion, diagnostics, hover, and more. It uses HTMLlsrs and CSSlsrs, our own modern and fast language services, designed to be integrated into language servers written in Rust or via WebAssembly.
