$ npm i -D eslint eslint-plugin-security eslint-config-emarsys

Then add it to your .eslintrc

{
  "extends": [
    "emarsys"
  ]
}

Eslint config properties like env or globals are strongly project specific so you have to set them in your own .eslintrc file.

For instance:

{
  "env": {
    "browser": true
  },
  "globals": {
    "React": true
  },
  "extends": [
    "emarsys"
  ]
}
