Bump a package version
npm version [<newversion> | major | minor | patch | build]Run 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 "build", "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.
