Ubuntu Manpage: npm-version - Bump a package version

NAME

npm-version - Bump a package version

'npm [-v | --version]' to print npm version
'npm view <pkg> version' to view a package's published version
'npm ls' to inspect current package/dependency versions

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 https://github.com/npm/node-semver#functions (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

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:

1. 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.

2. 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.

3. Bump version in package.json as requested (patch, minor, major, etc).

4. 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.

5. Commit and tag.

6. 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.

Configuration
allow-same-version
• Default: false

• Type: Boolean

Prevents throwing an error when npm version is used to set the new version to the same
value as the current version.

git-tag-version
• Default: true

• Type: Boolean

Commit and tag the version change.

commit-hooks
• Default: true

• Type: Boolean

Run git commit hooks when committing the version change.

sign-git-tag
• Default: false

• Type: Boolean

Pass the -s flag to git to sign the tag.

Note that you must have a default GPG key set up in your git config for this to work
properly.
