You can use docker to get the package.json version. In this example we tag and push with "latest" and package.json version:

.gitlab-ci.yml

docker-build-master:
  # Official docker image.
  image: docker:latest
  stage: build
  services:
    - docker:dind
  before_script:
    - docker login -u "$CI_REGISTRY_USER" -p "$CI_REGISTRY_PASSWORD" $CI_REGISTRY
  script:
    - export VERSION=$(docker run --rm -v "$PWD":/app:ro -w /app node:slim node -p "require('./package.json').version")
    - docker build --pull -t "$CI_REGISTRY_IMAGE" .
    - docker push "$CI_REGISTRY_IMAGE:latest"
    - docker image tag "$CI_REGISTRY_IMAGE:latest" "$CI_REGISTRY_IMAGE:$VERSION"
    - docker push "$CI_REGISTRY_IMAGE:$VERSION"
  only:
    - master
