VS Code: eslint

The extension uses the ESLint library installed in the opened workspace folder. If the folder doesn't provide one the extension looks for a global install version. If you haven't installed ESLint either locally or globally do so by running npm install eslint in the workspace folder for a local install or npm install -g eslint for a global install.
On new folders you might also need to create a .eslintrc configuration file. You can do this by either using the VS Code command Create ESLint configuration or by running the eslint command in a terminal. If you have installed ESLint globally (see above) then run eslint --init in a terminal. If you have installed ESLint locally then run .\node_modules\.bin\eslint --init under Windows and ./node_modules/.bin/eslint --init under Linux and Mac.
