Saving version number to package.json in Gitlab yaml

Question

I am able to successfully get the version number from my package.json and increment it, however I need to save the new version back to package.json and save it.

How can I do this in the below script in Gitlab

build_android:
  stage: build
  script:
    - export VERSION_NUMBER=$(node -p "require('./package.json').version")
    - echo "Current version number:" $VERSION_NUMBER
    - export NEW_VERSION_NUMBER=$(echo "$VERSION_NUMBER + 0.0.1" | bc)
    - echo "New version number:" $NEW_VERSION_NUMBER

I have tried adding

 - npm version $NEW_VERSION_NUMBER

to the end but the problem is the package.json is never saved to every subsequent build will use the original build number

With all of these answers, none of them address the issue of a gitlab loop. Each time you check into a repository it will trigger another build of the yaml. You need to add a flag so that the check in will be skipped and the yaml doesn't get fired over and over

You have to place the [skip ci] flag in your commit message or use the flag -o ci.skip in your git push.

- git clone https://${GITLAB_USER_LOGIN}@${CI_SERVER_HOST}/${CI_PROJECT_PATH}.git
    - git checkout $CI_COMMIT_REF_NAME
    - npm version minor --no-git-tag-version 
    - git commit -a -m "Bump version [skip ci]"
    - git push "https://${GITLAB_USER_LOGIN}@${CI_SERVER_HOST}/${CI_PROJECT_PATH}.git" "HEAD:${CI_COMMIT_REF_NAME}" -o **ci.skip**
