How to automatically push tag to git after npm version command?

Question

npm version:

Run this in a package directory to bump the version and write the new data back to package.json [..] If run in a git repo, it will also create a version commit and tag.

How do I configure npm/ wrap npm version command to automatically push tag to git?, i.e. an equivalent of:

npm version patch
+ [email protected]
git push origin v3.0.1

NPM documentation recommends adding a postversion script to the prackage.json, e.g.

"scripts": {
    "postversion": "git push && git push --tags && rm -rf build/temp"
}

However, this suggestion applies to a single package only and it is bad because it syncs all the tags, not just the last created tag.

Answer 1

Assuming the new tag is the only tag on the current revision something like this might work.

$ npm version patch
$ tag=$(git tag --points-at HEAD)
$ git push origin "$tag"

Otherwise you could try catching (and parsing) the output from npm version patch like this perhaps (assuming the output is always + [email protected] and the tag is always v<part after @).

$ tag=$(npm version patch 2>&1)
$ tag=v${tag#*@}
$ git push origin "$tag"

You could also try grabbing the available tags before the npm version patch call and then diffing that list against the available tags after which should find the new tag and you can push it.
