You need to use the babel-preset-stage-2 preset together with the env preset when using 8.10 as target.

The problem is, that the pure env 8.10 preset does not include the spread rest operator and import. So use

"presets": [
    ["env", {
      "targets": {
        "node": "8.10"
      }
    }],
    "stage-2"
  ],

We did the transistion yesterday for our projects and that way it works.

@OlzhasAlexandrov I updated my comment to include the dash (wrote the answer just too quickly 😄 ). Thanks for the correction.
