Lightrun for code-server

For some developers, VS Code for the Web is not an option for various security, compliance and compatability reasons. For these developers - who still want the creature comforts VS Code provides without having to rely on itself - there is the option of using an open-source, self-hosted version of VS Code for the Web called code-server.

Lightrun supports code-server out of the box - see installation instructione here. In addition, note that these instructions will work for developers who use externally-hosted version of VS Code (like GitLab's new Web IDE) too, so make sure to check it out if you're using any hosted version of VS Code.


Since Lightrun for runs completely within your browser, there are some limitations when compared to using Lightrun directly in your IDE.
