If you're using @edx/frontend-build, then you'll get this package for free. Otherwise, you can install it via:
npx install-peerdeps --dev @edx/eslint-config
This will install the package and all of its peer dependencies.
Then, once it's installed, create an .eslintrc.js file in the top-level directory of your project with the following contents:
module.exports = {
extends: "@edx/eslint-config",
}
