Modern language engineering with Langium
summary
Langium is a TypeScript-first framework that claims to turn a grammar into a working language with parsing, linking, scoping, validations, LSP support and code generation from a single grammar. It uses a Chevrotain-based parser, generates a typed semantic model and DI-friendly services, supports TypeScript-first framework workflows and two runtimes (frontend/backend language servers or browser-only architecture in a webworker). The demo builds a MiniLogo language, generates TypeScript canvas code, and the preview drawing and rename/validation features work end to end.
