NPM version

Note: If you only tag your repo using the CLI and not the GitHub UI, you can leave off the fetch. As npm version will use the "version" field in package.json to incremen the tag, not git tags.

Manual

$ git fetch --tags
$ npm version minor
$ git push --follow-tags

Or

$ git fetch --tags && npm version minor && git push --follow-tags

Package commands

Or set up your package.json:

{
    "scripts": {
        "preversion": "git fetch --tags",
        "postversion": "git push --follow-tags"
    }
}

And run:

$ npm version
