- # Frequently Asked Questions
-
- ## Why is the `package.json`’s version not updated in my repository?
-
- **semantic-release** takes care of updating the `package.json`’s version before publishing to [npm](https://www.npmjs.com).
-
- By default, only the published package will contains the version, which is the only place where it is *really* required, but the updated `package.json` will not be pushed to the Git repository
-
- However, the [`@semantic-release/git`](https://github.com/semantic-release/git) plugin can be used to push the updated `package.json` as well as other files to the Git repository.
-
- ## How can I use a npm build script that requires the `package.json`’s version ?
-
- The `package.json`’s version will be updated by the `semantic-release` command just before publishing to [npm](https://www.npmjs.com), therefore it won't be available for scripts ran before the `semantic-release` command.
-
- As the [`@semantic-release/npm`](https://github.com/semantic-release/npm) plugin uses the [npm CLI](https://docs.npmjs.com/cli/npm) to update the `package.json` version and publish the package, all [npm hook scripts](https://docs.npmjs.com/misc/scripts#description) will be executed.
-
- You can run your build script in:
- - the `prepublishOnly` or `prepack` hook so it will be executed during the `publish` step of `@semantic-release/npm`
- - the `postversion` hook so it will be executed during the `prepare` step of `@semantic-release/npm`, which allow for example to update files before committing them with the [`@semantic-release/git`](https://github.com/semantic-release/git) plugin
-
- If using npm hook scripts is not possible, and alternative solution is to [`@semantic-release/exec`](https://github.com/semantic-release/exec) plugin to run your script in the `prepare` step:
- ```json
- {
- "plugins": [
- "@semantic-release/commit-analyzer",
- "@semantic-release/release-notes-generator",
- "@semantic-release/npm",
- ["@semantic-release/exec", {
- "prepareCmd": "./my-build-script.sh ${nextRelease.version}",
- }],
- ]
- }
- ```
-
- ## Is there a way to preview which version would currently get published?
-
- Yes with the [dry-run options](../usage/configuration.md#dryrun) which prints to the console the next version to be published and the release notes.
-
- ## Can I use semantic-release with Yarn?
-
- If you are using a [local](../usage/installation.md#local-installation) **semantic-release** installation and run multiple CI jobs with different versions, the `yarn install` command will fail on jobs running with Node < 8 as **semantic-release** requires [Node >= 8.3](#why-does-semantic-release-require-node-version--83) and specifies it in its `package.json`s [`engines`](https://docs.npmjs.com/files/package.json#engines) key.
-
- The recommended solution is to use the [Yarn](https://yarnpkg.com) [--ignore-engines](https://yarnpkg.com/en/docs/cli/install#toc-yarn-install-ignore-engines) option to install the project dependencies on the CI environment, so Yarn will ignore the **semantic-release**'s `engines` key:
-
- ```bash
- $ yarn install --ignore-engines
- ```
-
- **Note**: Several CI services use Yarn by default if your repository contains a `yarn.lock` file. So you should override the install step to specify `yarn install --ignore-engines`.
-
- Alternatively you can use a [global](../usage/installation.md#global-installation) **semantic-release** installation and make sure to install and run the `semantic-release` command only in a CI jobs running with Node >= 8.3.
-
- If your CI environment provides [nvm](https://github.com/creationix/nvm) you can switch to Node 8 before installing and running the `semantic-release` command:
-
- ```bash
- $ nvm install 8 && yarn global add semantic-release && semantic-release
- ```
-
- See the [CI configuration recipes](../recipes/README.md#ci-configurations) for more details on specific CI environments.
-
- As `semantic-release` is recommended to be executed with [`npx`](https://www.npmjs.com/package/npx) an alternative is required for usage with Yarn. Even though it is possible to install npx with Yarn, it's not recommended. Yarn and npx would be using different cache locations.
-
- For [local installation](../usage/installation.md#local-installation) replace
- `npx semantic-release` with `yarn run semantic-release`.
-
- For [global installation](../usage/installation.md#global-installation) replace
- `npx semantic-release` with `yarn global add semantic-release && semantic-release`.
-
- ## Can I use semantic-release to publish non-JavaScript packages?
-
- Yes, **semantic-release** is a Node CLI application but it can be used to publish any type of packages.
-
- To publish a non-Node package (without a `package.json`) you would need to:
- - Use a [global](../usage/installation.md#global-installation) **semantic-release** installation
- - Set **semantic-release** [options](../usage/configuration.md#options) via [CLI arguments or rc file](../usage/configuration.md#configuration)
- - Make sure your CI job executing the `semantic-release` command has access to [Node >= 8](#why-does-semantic-release-require-node-version--83) to execute the `semantic-release` command
-
- See the [CI configuration recipes](../recipes/README.md#ci-configurations) for more details on specific CI environments.
-
- In addition you will need to configure the **semantic-release** [plugins](../usage/plugins.md#plugins) to disable the [`@semantic-release/npm`](https://github.com/semantic-release/npm) plugin which is used by default and use a plugin for your project type.
-
- If there is no specific plugin for your project type you can use the [`@semantic-release/exec`](https://github.com/semantic-release/exec) plugin to publish the release with a shell command.
-
- Here is a basic example to create [GitHub releases](https://help.github.com/articles/about-releases) and use a shell command to publish:
-
- ```json
- {
- "plugins": [
- "@semantic-release/commit-analyzer",
- "@semantic-release/release-notes-generator",
- "@semantic-release/github",
- ["@semantic-release/exec", {
- "prepareCmd" : "set-version ${nextRelease.version}",
- "publishCmd" : "publish-package"
- }]
- ]
- }
- ```
-
- **Note**: This is a theoretical example where the command `set-version` update the project version with the value passed as its first argument and `publish-package` publishes the package to a registry.
-
- See the [package managers and languages recipes](../recipes/README.md#package-managers-and-languages) for more details on specific project types.
-
- ## Can I use semantic-release with any CI service?
-
- Yes, **semantic-release** can be used with any CI service, as long as it provides:
- - A way to set [authentication](../usage/ci-configuration.md#authentication) via environment variables
- - A way to guarantee that the `semantic-release` command is [executed only after all the tests of all the jobs in the CI build pass](../usage/ci-configuration.md#run-semantic-release-only-after-all-tests-succeeded)
-
- See the [CI configuration recipes](../recipes/README.md#ci-configurations) for more details on specific CI environments.
-
- ## Can I run semantic-release on my local machine rather than on a CI server?
-
- Yes, you can by explicitly setting the [`--no-ci` CLI option](../usage/configuration.md#ci) option. You will also have to set the required [authentication](../usage/ci-configuration.md#authentication) via environment variables on your local machine, for example:
-
- ```bash
- $ NPM_TOKEN=<your_npm_token> GH_TOKEN=<your_github_token> npx semantic-release --no-ci
- ```
-
- However this is not the recommended approach, as running unit and integration tests on an independent machine before publishing software is a crucial part of the release workflow.
-
- ## Can I use semantic-release with GitLab?
-
- Yes, with the [`@semantic-release/gitlab-config`](https://github.com/semantic-release/gitlab-config) shareable configuration.
-
- See the [GitLab CI recipes](../recipes/gitlab-ci.md#using-semantic-release-with-gitlab-ci) for the CI configuration.
-
- ## Can I use semantic-release with any Git hosted environment?
-
- By default **semantic-release** uses the [`@semantic-release/github`](https://github.com/semantic-release/github) plugin to publish a [GitHub release](https://help.github.com/articles/about-releases). For other Git hosted environment the [`@semantic-release/git`](https://github.com/semantic-release/git) and [`@semantic-release/changelog`](https://github.com/semantic-release/changelog) plugins can be used via [plugins configuration](../usage/plugins.md).
-
- See the [`@semantic-release/git`](https://github.com/semantic-release/git#semantic-releasegit) [`@semantic-release/changelog`](https://github.com/semantic-release/changelog#semantic-releasechangelog) plugins documentation for more details.
-
- ## Can I skip the release to the npm registry?
-
- Yes, the publishing to the npm registry can be disabled with the [`npmPublish`](https://github.com/semantic-release/npm#options) option of the [`@semantic-release/npm`](https://github.com/semantic-release/npm) plugin. In addition the [`tarballDir`](https://github.com/semantic-release/npm#options) option allow to generate the package tarball in order to publish it to your repository with the [`@semantic-release/git`](https://github.com/semantic-release/git) or to a [GitHub release](https://help.github.com/articles/about-releases) with the [`@semantic-release/github`](https://github.com/semantic-release/github) plugin.
-
- See the [`@semantic-release/npm`](https://github.com/semantic-release/npm#semantic-releasenpm) plugin documentation for more details.
-
- ## How can I revert a release?
-
- If you have introduced a breaking bug in a release you have 2 options:
- - If you have a fix immediately ready, commit and push it (or merge it via a pull request) to the release branch
- - Otherwise [revert the commit](https://git-scm.com/docs/git-revert) that introduced the bug and push the revert commit (or merge it via a pull request) to the release branch
-
- In both cases **semantic-release** will publish a new release, so your package users' will get the fixed/reverted version.
-
- Depending on the package manager you are using, you might be able to un-publish or deprecate a release, in order to prevent users to download it by accident. For example npm allows you to [un-publish](https://docs.npmjs.com/cli/unpublish) in [next 72 hours](https://www.npmjs.com/policies/unpublish) after releasing or to [deprecate](https://docs.npmjs.com/cli/deprecate) a release.
-
- In any case **do not remove the Git tag associated with the buggy version**, otherwise **semantic-release** will later try to republish that version. Publishing a version after un-publishing is not supported by most package managers.
-
- **Note**: If you are using the default [Angular Commit Message Conventions](https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#-git-commit-guidelines) be aware that it uses a different revert commit format than the standard one created by [git revert](https://git-scm.com/docs/git-revert), contrary to what is [claimed in the convention](https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#revert). Therefore, if you revert a commit with [`git revert`](https://git-scm.com/docs/git-revert), use the [`--edit` option](https://git-scm.com/docs/git-revert#git-revert---edit) to format the message according to the [Angular revert commit message format](https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#revert). See [conventional-changelog/conventional-changelog#348](https://github.com/conventional-changelog/conventional-changelog/issues/348) for more details.
-
- ## Can I use `.npmrc` options?
-
- Yes, all the [npm configuration options](https://docs.npmjs.com/misc/config) are supported via the [`.npmrc`](https://docs.npmjs.com/files/npmrc) file at the root of your repository.
-
- See the [`@semantic-release/npm`](https://github.com/semantic-release/npm#npm-configuration) plugin documentation for more details.
-
- ## How can I set the access level of the published npm package?
-
- The [npm `access` option](https://docs.npmjs.com/misc/config#access) can be set in the [`.npmrc`](https://docs.npmjs.com/files/npmrc) file at the root of your repository:
-
- ```rc
- access=public
- ```
-
- Or with the `publishConfig.access` key in your project's `package.json`:
-
- ```json
- {
- "publishConfig": {
- "access": "public"
- }
- }
- ```
-
- ## Can I use semantic-release to publish a package on Artifactory?
-
- Any npm compatible registry is supported with the [`@semantic-release/npm`](https://github.com/semantic-release/npm) plugin. For Artifactory versions prior to 5.4, the legacy authentication has to be used (with `NPM_USERNAME`, `NPM_PASSWORD` and `NPM_EMAIL` [environment variables](https://github.com/semantic-release/npm#environment-variables)).
-
- See [npm registry authentication](https://github.com/semantic-release/npm#npm-registry-authentication) for more details.
-
- See [Artifactory - npm Registry](https://www.jfrog.com/confluence/display/RTF/Npm+Registry#NpmRegistry-AuthenticatingthenpmClient) documentation for Artifactiry configuration.
-
- ## Can I manually trigger the release of a specific version?
-
- You can trigger a release by pushing to your Git repository. You deliberately cannot trigger a *specific* version release, because this is the whole point of semantic-release.
-
- ## Can I exclude commits from the analysis?
-
- Yes, every commits that contains `[skip release]` or `[release skip]` in their message will be excluded from the commit analysis and won't participate in the release type determination.
-
- ## How can I change the type of commits that trigger a release?
-
- By default **semantic-release** uses the [Angular Commit Message Conventions](https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#-git-commit-guidelines) and triggers releases based on the following rules:
-
- | Commit | Release type |
- |-----------------------------|----------------------------|
- | Commit with breaking change | ~~Major~~ Breaking release |
- | Commit with type `feat` | ~~Minor~~ Feature release |
- | Commit with type `fix` | Patch release |
- | Commit with type `perf` | Patch release |
-
- See the [`@semantic-release/npm`](https://github.com/semantic-release/npm#npm-configuration) plugin documentation for more details.
-
- This is fully customizable with the [`@semantic-release/commit-analyzer`](https://github.com/semantic-release/commit-analyzer) plugin's [`release-rules` option](https://github.com/semantic-release/commit-analyzer#release-rules).
-
- ## Is it *really* a good idea to release on every push?
-
- It is indeed a great idea because it *forces* you to follow best practices. If you don’t feel comfortable releasing every feature or fix on your `master` you might not treat your `master` branch as intended.
-
- From [Understanding the GitHub Flow](https://guides.github.com/introduction/flow/index.html):
-
- > Branching is a core concept in Git, and the entire GitHub Flow is based upon it. There's only one rule: anything in the master branch is always deployable.
-
- If you need more control over the timing of releases, see [Triggering a release](../../README.md#triggering-a-release) for different options.
-
- **Note**: Only the codebase changes altering the published package will trigger a release (for example new features, bug fixes or performance improvements would trigger a release while refactoring or changing code style would not). See [How can I change the type of commits that trigger a release?](#how-can-i-change-the-type-of-commits-that-trigger-a-release) for more details.
-
- ## Can I set the initial release version of my package to `0.0.1`?
-
- This is not supported by **semantic-release** as it's not considered a good practice, mostly because [Semantic Versioning](https://semver.org) rules applies differently to major version zero.
-
- In early development phase when your package is not ready for production yet we recommend to publish releases on a distribution channel (for example npm’s [dist-tags](https://docs.npmjs.com/cli/dist-tag)) or to develop on a `dev` branch and merge it to `master` periodically. See [Triggering a release](../../README.md#triggering-a-release) for more details on those solutions.
-
- See [“Introduction to SemVer” - Irina Gebauer](https://blog.greenkeeper.io/introduction-to-semver-d272990c44f2) for more details on [Semantic Versioning](https://semver.org) and the recommendation to start at version `1.0.0`.
-
- ## Can I trust semantic-release with my releases?
-
- **semantic-release** has a full unit and integration test suite that tests `npm` publishes against the [npm-registry-couchapp](https://github.com/npm/npm-registry-couchapp).
-
- In addition the [verify conditions step](../../README.md#release-steps) verifies that all necessary conditions for proceeding with a release are met, and a new release will be performed [only if all your tests pass](../usage/ci-configuration.md#run-semantic-release-only-after-all-tests-succeeded).
-
- ## Why does semantic-release require Node version >= 8.3?
-
- **semantic-release** is written using the latest [ECMAScript 2017](https://www.ecma-international.org/publications/standards/Ecma-262.htm) features, without transpilation which **requires Node version 8.3 or higher**.
-
- See [Node version requirement](../support/node-version.md#node-version-requirement) for more details and solutions.
-
- ## What is npx?
-
- [`npx`](https://www.npmjs.com/package/npx) – short for "npm exec" – is a CLI to find and execute npm binaries within the local `node_modules` folder or in the $PATH. If a binary can't be located npx will download the required package and execute it from its cache location.
- The tool is bundled with [npm](https://www.npmjs.com/package/npm) >= 5.2, or can be installed via `npm install -g npx`.
- For more details and motivation read the [introductory blog post](https://medium.com/@maybekatz/introducing-npx-an-npm-package-runner-55f7d4bd282b) by [@zkat](https://github.com/zkat).
