Lit Component for Monaco Languageclient

The component can be fully configured with inlined JavaScript. It can be configured as regular or diff editor.

Help / Hints

Proper styling of at least the Diff Editor require that the codicon font is loaded outside the web component. Due to limitations of the Shadow DOM this can unfortunately not be transparently handled by the web component and requires user code adjustments shown here and monaco-editor sample).
