Configuration

<!-- AUTOGENERATED CONFIG DESCRIPTIONS -->

Description

Run this in a package directory to bump the version and write the new data
back to package.json, package-lock.json, and, if present,
npm-shrinkwrap.json.

The newversion argument should be a valid semver string, a valid second
argument to semver.inc (one
of patch, minor, major, prepatch, preminor, premajor,
prerelease), or from-git. In the second case, the existing version will
be incremented by 1 in the specified field. from-git will try to read
the latest git tag, and use that as the new npm version.

If run in a git repo, it will also create a version commit and tag. This
behavior is controlled by git-tag-version (see below), and can be
disabled on the command line by running npm --no-git-tag-version version.
It will fail if the working directory is not clean, unless the -f or
--force flag is set.

If supplied with -m or --message 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:

$ npm config set sign-git-tag true
$ npm version patch

You need a passphrase to unlock the secret key for

If preversion, version, or postversion are in the scripts property
of the package.json, they will be executed as part of running npm version.

The exact order of execution is as follows:

•

Check to make sure the git working directory is clean before we get

started. Your scripts may add files to the commit in future steps.
This step is skipped if the --force flag is set.

•

Run the preversion script. These scripts have access to the old

version in package.json. A typical use would be running your full
test suite before deploying. Any files you want added to the commit
should be explicitly added using git add.

•

Bump version in package.json as requested (patch, minor,

major, etc).

•

Run the version script. These scripts have access to the new version

in package.json (so they can incorporate it into file headers in
generated files for example). Again, scripts should explicitly add
generated files to the commit using git add.

	•		Commit and tag.
	•		Run the postversion script. Use it to clean up the file system or

automatically push the commit and/or tag.

Take the following example:

{
"scripts": {
"preversion": "npm test",
"version": "npm run build && git add -A dist",
"postversion": "git push && git push --tags && rm -rf build/temp"
}
}

This runs all your tests and proceeds only if they pass. Then runs your
build script, and adds everything in the dist directory to the commit.
After the commit, it pushes the new commit and tag up to the server, and
deletes the build/temp directory.
