ESLint / Prettier column width

To increase the column width to 120 I had to change both .eslintrc and .prettierrc. Then VSCode Format Document command worked as expected.

.eslintrc

"rules": {
  "max-len":
      [
          "error",
          {
              "code": 120
          }
      ]
}

.prettierrc

{
  "printWidth": 120
}
