npm version [<newversion> | major | minor | patch]
DESCRIPTIONRun this in a package directory to bump the version and write the new data back to the package.json file.
The newversion argument should be a valid semver string, or a valid second argument to semver.inc (one of "patch", "minor", or "major"). In the second case, the existing version will be incremented by 1 in the specified field.
If run in a git repo, it will also create a version commit and tag, and fail if the repo is not clean.
If supplied with --message (shorthand: -m) config option, npm will use it as a commit message when creating a version commit. If the message config contains %s then that will be replaced with the resulting version number. For example:
npm version patch -m "Upgrade to %s for reasons"
If the sign-git-tag config is set, then the tag will be signed using the -s flag to git. Note that you must have a default GPG key set up in your git config for this to work properly. For example:
