Standard Version
A utility for versioning using semver and CHANGELOG generation powered by Conventional Commits.
Having problems? Want to contribute? Join us on the node-tooling community Slack.
How It Works:
- Follow the Conventional Commits Specification in your repository.
- When you're ready to release, run
standard-version
.
standard-version
will then do the following:
- Retrieve the current version of your repository by looking at
bumpFiles
[1], falling back to the last git tag
. bump
the version in bumpFiles
[1] based on your commits.- Generates a
changelog
based on your commits (uses conventional-changelog under the hood). - Creates a new
commit
including your bumpFiles
[1] and updated CHANGELOG. - Creates a new
tag
with the new version number.
bumpFiles
, packageFiles
and updaters
standard-version
uses a few key concepts for handling version bumping in your project.
packageFiles
– User-defined files where versions can be read from and be "bumped".
- Examples:
package.json
, manifest.json
- In most cases (including the default),
packageFiles
are a subset of bumpFiles
.
bumpFiles
– User-defined files where versions should be "bumped", but not explicitly read from.
- Examples:
package-lock.json
, npm-shrinkwrap.json
updaters
– Simple modules used for reading packageFiles
and writing to bumpFiles
.
By default, standard-version
assumes you're working in a NodeJS based project... because of this, for the majority of projects you might never need to interact with these options.
That said, if you find your self asking How can I use standard-version for additional metadata files, languages or version files? – these configuration options will help!
Installing standard-version
As a local npm run
script
Install and add to devDependencies
:
npm i --save-dev standard-version
Add an npm run
script to your package.json
:
{
"scripts": {
"release": "standard-version"
}
}
Now you can use npm run release
in place of npm version
.
This has the benefit of making your repo/package more portable, so that other developers can cut releases without having to globally install standard-version
on their machine.
As global bin
Install globally (add to your PATH
):
npm i -g standard-version
Now you can use standard-version
in place of npm version
.
This has the benefit of allowing you to use standard-version
on any repo/package without adding a dev dependency to each one.
Using npx
As of npm@5.2.0
, npx
is installed alongside npm
. Using npx
you can use standard-version
without having to keep a package.json
file by running: npx standard-version
.
This method is especially useful when using standard-version
in non-JavaScript projects.
Configuration
You can configure standard-version
either by:
- Placing a
standard-version
stanza in your package.json
(assuming
your project is JavaScript). - Creating a
.versionrc
, .versionrc.json
or .versionrc.js
.
- If you are using a
.versionrc.js
your default export must be a configuration object, or a function returning a configuration object.
Any of the command line parameters accepted by standard-version
can instead
be provided via configuration. Please refer to the conventional-changelog-config-spec for details on available configuration options.
Customizing CHANGELOG Generation
By default (as of 6.0.0
), standard-version
uses the conventionalcommits preset.
This preset:
- Adheres closely to the conventionalcommits.org
specification.
- Is highly configurable, following the configuration specification
maintained here.
- We've documented these config settings as a recommendation to other tooling makers.
There are a variety of dials and knobs you can turn related to CHANGELOG generation.
As an example, suppose you're using GitLab, rather than GitHub, you might modify the following variables:
commitUrlFormat
: the URL format of commit SHAs detected in commit messages.compareUrlFormat
: the URL format used to compare two tags.issueUrlFormat
: the URL format used to link to issues.
Making these URLs match GitLab's format, rather than GitHub's.
CLI Usage
NOTE: To pass nested configurations to the CLI without defining them in the package.json
use dot notation as the parameters e.g. --skip.changelog
.
First Release
To generate your changelog for your first release, simply do:
npm run release -- --first-release
standard-version --first-release
npx standard-version --first-release
This will tag a release without bumping the version bumpFiles
1.
When you are ready, push the git tag and npm publish
your first release. \o/
Cutting Releases
If you typically use npm version
to cut a new release, do this instead:
npm run release
standard-version
As long as your git commit messages are conventional and accurate, you no longer need to specify the semver type - and you get CHANGELOG generation for free! \o/
After you cut a release, you can push the new git tag and npm publish
(or npm publish --tag next
) when you're ready.
Release as a Pre-Release
Use the flag --prerelease
to generate pre-releases:
Suppose the last version of your code is 1.0.0
, and your code to be committed has patched changes. Run:
npm run release -- --prerelease
This will tag your version as: 1.0.1-0
.
If you want to name the pre-release, you specify the name via --prerelease <name>
.
For example, suppose your pre-release should contain the alpha
prefix:
npm run release -- --prerelease alpha
This will tag the version as: 1.0.1-alpha.0
Release as a Target Type Imperatively (npm version
-like)
To forgo the automated version bump use --release-as
with the argument major
, minor
or patch
.
Suppose the last version of your code is 1.0.0
, you've only landed fix:
commits, but
you would like your next release to be a minor
. Simply run the following:
npm run release -- --release-as minor
npm run release -- --release-as 1.1.0
You will get version 1.1.0
rather than what would be the auto-generated version 1.0.1
.
NOTE: you can combine --release-as
and --prerelease
to generate a release. This is useful when publishing experimental feature(s).
Prevent Git Hooks
If you use git hooks, like pre-commit, to test your code before committing, you can prevent hooks from being verified during the commit step by passing the --no-verify
option:
npm run release -- --no-verify
standard-version --no-verify
Signing Commits and Tags
If you have your GPG key set up, add the --sign
or -s
flag to your standard-version
command.
Lifecycle Scripts
standard-version
supports lifecycle scripts. These allow you to execute your
own supplementary commands during the release. The following
hooks are available and execute in the order documented:
prerelease
: executed before anything happens. If the prerelease
script returns a
non-zero exit code, versioning will be aborted, but it has no other effect on the
process.prebump
/postbump
: executed before and after the version is bumped. If the prebump
script returns a version #, it will be used rather than
the version calculated by standard-version
.prechangelog
/postchangelog
: executes before and after the CHANGELOG is generated.precommit
/postcommit
: called before and after the commit step.pretag
/posttag
: called before and after the tagging step.
Simply add the following to your package.json to configure lifecycle scripts:
{
"standard-version": {
"scripts": {
"prebump": "echo 9.9.9"
}
}
}
As an example to change from using GitHub to track your items to using your projects Jira use a
postchangelog
script to replace the url fragment containing 'https://github.com/`myproject`/issues/'
with a link to your Jira - assuming you have already installed replace
{
"standard-version": {
"scripts": {
"postchangelog": "replace 'https://github.com/myproject/issues/' 'https://myjira/browse/' CHANGELOG.md"
}
}
}
Skipping Lifecycle Steps
You can skip any of the lifecycle steps (bump
, changelog
, commit
, tag
),
by adding the following to your package.json:
{
"standard-version": {
"skip": {
"changelog": true
}
}
}
Committing Generated Artifacts in the Release Commit
If you want to commit generated artifacts in the release commit (e.g. #96), you can use the --commit-all
or -a
flag. You will need to stage the artifacts you want to commit, so your release
command could look like this:
"prerelease": "webpack -p --bail",
"release": "git add <file(s) to commit> && standard-version -a"
Dry Run Mode
running standard-version
with the flag --dry-run
allows you to see what
commands would be run, without committing to git or updating files.
npm run release -- --dry-run
standard-version --dry-run
Prefix Tags
Tags are prefixed with v
by default. If you would like to prefix your tags with something else, you can do so with the -t
flag.
standard-version -t @scope/package\@
This will prefix your tags to look something like @scope/package@2.0.0
If you do not want to have any tag prefix you can use the -t
flag without value.
CLI Help
npm run release -- --help
standard-version --help
Code Usage
const standardVersion = require('standard-version')
standardVersion({
noVerify: true,
infile: 'docs/CHANGELOG.md',
silent: true
}).then(() => {
}).catch(err => {
console.error(`standard-version failed with message: ${err.message}`)
})
TIP: Use the silent
option to prevent standard-version
from printing to the console
.
FAQ
How is standard-version
different from semantic-release
?
semantic-release
is described as:
semantic-release automates the whole package release workflow including: determining the next version number, generating the release notes and publishing the package.
While both are based on the same foundation of structured commit messages, standard-version
takes a different approach by handling versioning, changelog generation, and git tagging for you without automatic pushing (to GitHub) or publishing (to an npm registry). Use of standard-version
only affects your local git repo - it doesn't affect remote resources at all. After you run standard-version
, you can review your release state, correct mistakes and follow the release strategy that makes the most sense for your codebase.
We think they are both fantastic tools, and we encourage folks to use semantic-release
instead of standard-version
if it makes sense for their use-case.
Should I always squash commits when merging PRs?
The instructions to squash commits when merging pull requests assumes that one PR equals, at most, one feature or fix.
If you have multiple features or fixes landing in a single PR and each commit uses a structured message, then you can do a standard merge when accepting the PR. This will preserve the commit history from your branch after the merge.
Although this will allow each commit to be included as separate entries in your CHANGELOG, the entries will not be able to reference the PR that pulled the changes in because the preserved commit messages do not include the PR number.
For this reason, we recommend keeping the scope of each PR to one general feature or fix. In practice, this allows you to use unstructured commit messages when committing each little change and then squash them into a single commit with a structured message (referencing the PR number) once they have been reviewed and accepted.
Can I use standard-version
for additional metadata files, languages or version files?
As of version 7.1.0
you can configure multiple bumpFiles
and packageFiles
.
-
Specify a custom bumpFile
"filename
", this is the path to the file you want to "bump"
-
Specify the bumpFile
"updater
", this is how the file will be bumped.
a. If your using a common type, you can use one of standard-version
's built-in updaters
by specifying a type
.
b. If your using an less-common version file, you can create your own updater
.
{
"bumpFiles": [
{
"filename": "MY_VERSION_TRACKER.txt",
"type": "plain-text"
},
{
"filename": "a/deep/package/dot/json/file/package.json",
"type": "json"
},
{
"filename": "VERSION_TRACKER.json",
"updater": "standard-version-updater.js"
}
]
}
Custom updater
s
An updater
is expected to be a Javascript module with atleast two methods exposed: readVersion
and writeVersion
.
readVersion(contents = string): string
This method is used to read the version from the provided file contents.
The return value is expected to be a semantic version string.
writeVersion(contents = string, version: string): string
This method is used to write the version to the provided contents.
The return value will be written directly (overwrite) to the provided file.
Let's assume our VERSION_TRACKER.json
has the following contents:
{
"tracker": {
"package": {
"version": "1.0.0"
}
}
}
An acceptable standard-version-updater.js
would be:
const stringifyPackage = require('stringify-package')
const detectIndent = require('detect-indent')
const detectNewline = require('detect-newline')
module.exports.readVersion = function (contents) {
return JSON.parse(contents).tracker.package.version;
}
module.exports.writeVersion = function (contents, version) {
const json = JSON.parse(contents)
let indent = detectIndent(contents).indent
let newline = detectNewline(contents)
json.tracker.package.version = version
return stringifyPackage(json, indent, newline)
}
