It may be the case you don't want to install and maintain multiple versions of Node (10, 12, 14... future releases) in your machine, or you don't want to install npm packages globally.
Keep your Screeps-TypeScript project isolated with its dependencies within a container!
VS Code supports remote development and allows you to use a container as a full-featured development environment. You can open a project mounted into a Docker container to edit with full code completions, code navigation, debugging, and more.
Refer to VS Code documentation if you want to understand more about remote development:
For Windows, set source code locations you want to open in a container. In Docker, right-click and select Settings / Preferences > Shared Drives / File Sharing. See Container tips if you hit trouble with sharing.
For Linux, see supported platforms. From the terminal, run sudo usermod -aG docker $USER to add your user to the docker group. This setting takes effect after you sign out and back in again.

The container pre-installs and configures all Pre-Requisites for this project + other utils for your daily basis:
