standard-versionis deprecated. If you're a GitHub user, I recommend release-please as an alternative. If you're unable to use GitHub Actions, or if you need to stick withstandard-versionfor some other reason, you can use the commit-and-tag-version fork ofstandard-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
packageFiles[1], falling back to the lastgit tag. bumpthe version inbumpFiles[1] based on your commits.- Generates a
changelogbased on your commits (uses conventional-changelog under the hood). - Creates a new
commitincluding yourbumpFiles[1] and updated CHANGELOG. - Creates a new
tagwith the new version number.
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),
packageFilesare a subset ofbumpFiles.
- Examples:
bumpFiles– User-defined files where versions should be "bumped", but not explicitly read from.- Examples:
package-lock.json,npm-shrinkwrap.json
- Examples:
updaters– Simple modules used for readingpackageFilesand writing tobumpFiles.
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!
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.
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.
As of [email protected], 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.
You can configure standard-version either by:
- Placing a
standard-versionstanza in yourpackage.json(assuming your project is JavaScript). - Creating a
.versionrc,.versionrc.jsonor.versionrc.js.
- If you are using a
.versionrc.jsyour 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.
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.
NOTE: To pass nested configurations to the CLI without defining them in the
package.jsonuse dot notation as the parameterse.g. --skip.changelog.
To generate your changelog for your first release, simply do:
# npm run script
npm run release -- --first-release
# global bin
standard-version --first-release
# npx
npx standard-version --first-releaseThis will tag a release without bumping the version bumpFiles1.
When you are ready, push the git tag and npm publish your first release. \o/
If you typically use npm version to cut a new release, do this instead:
# npm run script
npm run release
# or global bin
standard-versionAs 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.
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 script
npm run release -- --prereleaseThis 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 script
npm run release -- --prerelease alphaThis will tag the version as: 1.0.1-alpha.0
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 script
npm run release -- --release-as minor
# Or
npm run release -- --release-as 1.1.0You will get version 1.1.0 rather than what would be the auto-generated version 1.0.1.
NOTE: you can combine
--release-asand--prereleaseto generate a release. This is useful when publishing experimental feature(s).
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 script
npm run release -- --no-verify
# or global bin
standard-version --no-verifyIf you have your GPG key set up, add the --sign or -s flag to your standard-version command.
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 theprereleasescript 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 theprebumpscript returns a version #, it will be used rather than the version calculated bystandard-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"
}
}
}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
}
}
}If you want to commit generated artifacts in the release commit, 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:
{
"standard-version": {
"scripts": {
"prerelease": "webpack -p --bail && git add <file(s) to commit>"
}
}
}{
"scripts": {
"release": "standard-version -a"
}
}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 script
npm run release -- --dry-run
# or global bin
standard-version --dry-runTags 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/[email protected]
If you do not want to have any tag prefix you can use the -t flag and provide it with an empty string as value.
Note: simply -t or --tag-prefix without any value will fallback to the default 'v'
# npm run script
npm run release -- --help
# or global bin
standard-version --helpconst standardVersion = require('standard-version')
// Options are the same as command line, except camelCase
// standardVersion returns a Promise
standardVersion({
noVerify: true,
infile: 'docs/CHANGELOG.md',
silent: true
}).then(() => {
// standard-version is done
}).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.
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.
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.
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 you're using a common type, you can use one ofstandard-version's built-inupdatersby specifying atype. b. If your using an less-common version file, you can create your ownupdater.
// .versionrc
{
"bumpFiles": [
{
"filename": "MY_VERSION_TRACKER.txt",
// The `plain-text` updater assumes the file contents represents the version.
"type": "plain-text"
},
{
"filename": "a/deep/package/dot/json/file/package.json",
// The `json` updater assumes the version is available under a `version` key in the provided JSON document.
"type": "json"
},
{
"filename": "VERSION_TRACKER.json",
// See "Custom `updater`s" for more details.
"updater": "standard-version-updater.js"
}
]
}If using .versionrc.js as your configuration file, the updater may also be set as an object, rather than a path:
// .versionrc.js
const tracker = {
filename: 'VERSION_TRACKER.json',
updater: require('./path/to/custom-version-updater')
}
module.exports = {
bumpFiles: [tracker],
packageFiles: [tracker]
}An updater is expected to be a Javascript module with atleast two methods exposed: readVersion and writeVersion.
This method is used to read the version from the provided file contents.
The return value is expected to be a semantic version 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:
// standard-version-updater.js
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)
