The Clawject Language Service provides code editors (VSCode, WebStorm, etc.) with a way to get errors and navigation inside Beans, Contexts, etc.
Clawject package provide language service,
but it can't be used directly because TypeScript not allows using language services that are not package itself,
so @clawject/language-service package have @clawject/di as a dependency and re-exporting its language service.
You can read more about language service in the documentation
