VS Code and Javascript Debugging

I’ve been tinkering on a Discord-bot in Javascript using Node.js, together with my best friend.

For easier testing, we run the bot in Docker, so we don’t have all the dependencies littering our computers. We do want to be able to debug the bot, though, which is where I ran into an article on the internet by oneturkmen. The article has been deleted, but the GitHub-repository is (at the time of writing this article) still available here.

I’m running Windows 10 Professional, with Docker installed using the ‘Containers’-feature of Windows 10.

First, we have to have a docker-compose.yml file, with the following data:

#docker-compose run --rm node /bin/bash
node:
    image: node:carbon
    working_dir: /usr/src/app
    volumes:
        - .:/usr/src/app
    environment:
        - DISCORD_TOKEN
    ports:
      - "9229:9229"
    command: node -r dotenv/config --inspect=0.0.0.0 app.js
