Do NOT USE APT, it is available and seems to work but this is a node module. Don't be stupid, use npm. Note the mind-bogglingly-insane number of dependencies. Node world, you scare me...
npm install -g eslint
If you have an existing .eslintrc.js that works well in another project, JUST COPY IT to the root of the new vscode folder-based project. Otherwise, this will step you through it. Use the google format as a baseline:
cd myproject eslint --init
- vscode integration
- Get the eslint extension
- Restart vscode and open a project with JS files. Should be all you need.
