    Craft: Universal Release Tool (And More)

    Travis GitHub release npm version license

    craft is a command line tool that helps to automate and pipeline package releases. It suggests, and then enforces a specific workflow for managing release branches, changelogs, artifact publishing, etc.

    Table of Contents



    craft is distributed as a minified single JS binary.

    npm (not recommended)

    Recommendation is to used this file directly but one can also install craft as an NPM package and can be installed via yarn or npm:

    yarn global add @sentry/craft
    npm install -g @sentry/craft


    $ craft -h
    craft <command>
      craft prepare NEW-VERSION  🚢 Prepare a new release branch
                              [aliases: p, prerelease, prepublish, prepare, release]
      craft publish NEW-VERSION  🛫 Publish artifacts         [aliases: pp, publish]
      craft targets              List defined targets as JSON array

      --log-level    Logging level
              [choices: "Fatal", "Error", "Warn", "Log", "Info", "Success", "Debug",
                                     "Trace", "Silent", "Verbose"] [default: "Info"]
      -v, --version  Show version number                                   [boolean]
      -h, --help     Show help                                             [boolean]


    • When interacting with remote GitHub repositories, craft uses the remote origin by default. If you have a different setup, set the CRAFT_REMOTE environment variable or the --remote option to the git remote you are using.

    Global Configuration

    Global configuration for craft can be done either by using environment variables or by adding values to a configuration file (see below).

    All command line flags can be set through environment variables by prefixing them with CRAFT_ and converting them to UPPERCASE_UNDERSCORED versions:


    Since Craft heavily relies on GitHub, it needs the GITHUB_TOKEN environment variable to be set to a proper GitHub Personal Access Token for almost anything. The token only needs repo scope (repo:status and public_repo subscopes, to be precise).

    Additional environment variables may be required when publishing to specific targets (e.g. TWINE_USERNAME and TWINE_PASSWORD for PyPI target).

    Environment Files

    craft will read configuration variables (keys, tokens, etc.) from the following locations:

    • $HOME/.craft.env
    • $PROJECT_DIR/.craft.env
    • the shell's environment

    where $HOME is the current user's home directory, and $PROJECT_DIR is the directory where .craft.yml is located.

    These locations will be checked in the order specified above, with values found in one location overwriting anything found in previous locations. In other words, environment variables will take precedence over either configuration file, and the project-specific file will take precedence over the file in $HOME.

    The env files must be written in shell (sh/bash) format. Leading export is allowed.


    # ~/.craft.env
    export NUGET_API_TOKEN=abcdefgh


    craft prepare: Preparing a New Release

    This command will create a new release branch, check the changelog entries, run a version-bumping script, and push this branch to GitHub. We expect that CI triggered by pushing this branch will result in release artifacts being built and uploaded to the artifact provider you wish to use during the subsequent publish step.

    craft prepare NEW-VERSION

    craft publish: Publishing the Release

    The command will find a release branch for the provided version. The normal flow is for this release branch to be created automatically by craft prepare, but that's not strictly necessary. Then, it subscribes to the latest status checks on that branch. Once the checks pass, it downloads the release artifacts from the artifact provider configured in .craft.yml and uploads them to the targets named on the command line (and pre-configured in .craft.yml).

    craft publish NEW-VERSION

    Let's imagine we want to release a new version of our package, and the version in question is 1.2.3.

    We run prepare command first:

    $ craft prepare 1.2.3

    After some basic sanity checks this command creates a new release branch release/1.2.3, runs the version-bumping script (scripts/, commits the changes made by the script, and then pushes the new branch to GitHub. At this point CI systems kick in, and the results of those builds, as well as built artifacts (binaries, NPM archives, Python wheels) are gradually uploaded to GitHub.

    To publish the built artifacts we run publish:

    $ craft publish 1.2.3

    This command will find our release branch (release/1.2.3), check the build status of the respective git revision in GitHub, and then publish available artifacts to configured targets (for example, to GitHub and NPM in the case of Craft).

    Configuration File: .craft.yml

    Project configuration for craft is stored in .craft.yml configuration file, located in the project root.

    GitHub project

    Craft tries to determine the GitHub repo information from the local git repo and its remotes configuration. However, since publish command does not require a local git checkout, you may want to hard-code this information into the configuration itself:

      owner: getsentry
      repo: sentry-javascript

    Pre-release Command

    This command will run on your newly created release branch as part of prepare command. By default, it is set to bash scripts/ Please refer to the Pre-release version bumping script conventions section for more details.

    preReleaseCommand: bash scripts/

    Post-release Command

    This command will run after a successful publish. By default, it is set to bash scripts/ It will not error if the default script is missing though, as this may not be needed by all projects. Please refer to the Post-release script conventions section for more details.

    postReleaseCommand: bash scripts/

    Release Branch Name

    This overrides the prefix for the release branch name. The full branch name used for a release is {releaseBranchPrefix}/{version}. The prefix defaults to "release".

    releaseBranchPrefix: publish

    Changelog Policies

    craft can help you to maintain change logs for your projects. At the moment, craft supports two approaches: simple, and auto to changelog management.

    In simple mode, craft prepare will remind you to add a changelog entry to the changelog file ( by default).

    In auto mode, craft prepare will use the following logic:

    1. If there's already an entry for the given version, use that
    2. Else if there is an entry named Unreleased, rename that to the given version
    3. Else, create a new section for the version and populate it with the changes since the last version. It uses GitHub Milestones to provide a concise and rich changelog. If the PRs are associated with a milestone, the milestone title and description are used as the changelog entry alongside a brief list of associated PRs. Any individual commits and PRs are listed under the "Various improvements & fixes" section at the bottom. Check out Craft's own releases as example.


    Option Description
    changelog optional. Path to the changelog file. Defaults to
    changelogPolicy optional. Changelog management mode (none, simple, or auto). Defaults to none.

    Example (simple):

    changelog: CHANGES
    changelogPolicy: simple

    Valid changelog example:

    ## 1.3.5
    * Removed something
    ## 1.3.4
    * Added something

    Example (auto):

    changelog: CHANGES
    changelogPolicy: auto

    Changelog with staged changes example:

    ## Unreleased
    * Removed something
    ## 1.3.4
    * Added something

    Additionally, .craft.yml is used for listing targets where you want to publish your new release.

    Minimal Version

    It is possible to specify minimal craft version that is required to work with your configuration.


    minVersion: '0.5.0'

    Required Files

    You can provide a list of patterns for files that have to be available before proceeding with publishing. In other words, for every pattern in the given list there has to be a file present that matches that pattern. This might be helpful to ensure that we're not trying to do an incomplete release.


      - /^sentry-craft.*\.tgz$/
      - /^$/

    Status Provider

    You can configure which status providers craft will use to check for your build status. By default, it will use GitHub but you can add more providers if needed.


    Option Description
    name Name of the status provider: only github (default) for now.
    config In case of github: may include contexts key that contains a list of required contexts (checks)


      name: github
          - Travis CI - Branch

    Artifact Provider

    You can configure which artifact providers craft will use to fetch artifacts from. By default, GitHub is used, but in case you don't need use any artifacts in your project, you can set it to none.


    Option Description
    name Name of the artifact provider: github (default), gcs, or none


      name: none

    Target Configurations

    The configuration specifies which release targets to run for the repository. To run more targets, list the target identifiers under the targets key in .craft.yml.


      - name: npm
      - name: github
      - name: registry
        id: browser
        type: sdk
        onlyIfPresent: /^sentry-browser-.*\.tgz$/
        includeNames: /\.js$/
          - algorithm: sha384
            format: base64
          canonical: 'npm:@sentry/browser'
      - name: registry
        id: node
        type: sdk
        onlyIfPresent: /^sentry-node-.*\.tgz$/
          canonical: 'npm:@sentry/node'

    Per-target options

    The following options can be applied to every target individually:

    Name Description
    includeNames optional. Regular expression: only matched files will be processed by the target. There is one special case that includeNames supports.
    excludeNames optional. Regular expression: the matched files will be skipped by the target. Matching is performed after testing for inclusion (via includeNames).
    id optional. A unique id for the target type so one can refer to that target individually with the -t option with the publish command like -t registry[browser]. (see the example config above)

    If neither option is included, all artifacts for the release will be processed by the target.


      - name: github
        includeNames: /^.*\.exe$/
        excludeNames: /^test.exe$/

    GitHub (github)

    Create a release on Github. If a Markdown changelog is present in the repository, this target tries to read the release name and description from the changelog. Otherwise, defaults to the tag name and tag's commit message.

    If previewReleases is set to true (which is the default), the release created on GitHub will be marked as a pre-release version if the release name contains any one of preview, pre, rc, dev,alpha, beta, unstable, a, or b.


    Name Description
    GITHUB_TOKEN Personal GitHub API token (see


    Option Description
    tagPrefix optional. Prefix for new git tags (e.g. "v"). Empty by default.
    previewReleases optional. Automatically detect and create preview releases. true by default.
    annotatedTag optional. Creates an annotated tag, set to false for lightweight tag. true by default.


      - name: github
        tagPrefix: v
        previewReleases: false
        annotatedTag: false

    NPM (npm)

    Releases an NPM package to the public registry. This requires a package tarball generated by npm pack in the artifacts. The file will be uploaded to the registry with npm publish, or with yarn publish if npm is not found. This requires NPM to be authenticated with sufficient permissions to publish the package.


    The npm utility must be installed on the system.

    Name Description
    NPM_TOKEN An automation token allowed to publish.
    NPM_BIN optional. Path to the npm executable. Defaults to npm
    YARN_BIN optional. Path to the yarn executable. Defaults to yarn
    CRAFT_NPM_USE_OTP optional. If set to "1", you will be asked for an OTP (for 2FA)


    Option Description
    access optional. Visibility for scoped packages: restricted (default) or public


      - name: npm
        access: public

    Python Package Index (pypi)

    The twine Python package must be installed on the system.

    Name Description
    TWINE_USERNAME User name for PyPI with access rights for the package
    TWINE_PASSWORD Password for the PyPI user
    TWINE_BIN optional. Path to twine. Defaults to twine




      - name: pypi

    Homebrew (brew)

    Pushes a new or updated homebrew formula to a brew tap repository. The formula is committed directly to the master branch of the tap on GitHub, therefore the bot needs rights to commit to master on that repository. Therefore, formulas on homebrew/core are not supported, yet.

    The tap is configured with the mandatory tap parameter in the same format as the brew utility. A tap <org>/<name> will expand to the GitHub repository<org>/homebrew-<name>.

    The formula contents are given as configuration value and can be interpolated with Mustache template syntax ({{ variable }}). The interpolation context contains the following variables:

    • version: The new version
    • revision: The tag's commit SHA
    • checksums: A map containing sha256 checksums for every release asset. Use the full filename to access the sha, e.g. checksums.MyProgram-x86


    Name Description
    GITHUB_TOKEN Personal GitHub API token (seeh ttps://


    Option Description
    tap The name of the homebrew tap used to access the GitHub repo
    template The template for contents of the formula file (ruby code)
    formula optional. Name of the formula. Defaults to the repository name
    path optional. Path to store the formula in. Defaults to Formula


      - name: brew
        tap: octocat/tools # Expands to
        formula: myproject # Creates the file myproject.rb
        path: HomebrewFormula # Creates the file in HomebrewFormula/
        template: >
          class MyProject < Formula
            desc "This is a test for homebrew formulae"
            homepage ""
            url "{{version}}/binary-darwin"
            version "{{version}}"
            sha256 "{{checksums.binary-darwin}}"
            def install
              mv "binary-darwin", "myproject"
              bin.install "myproject"

    NuGet (nuget)

    Uploads packages to NuGet via .NET Core. By default, craft publishes all packages with .nupkg extension.


    The dotnet tool must be available on the system.

    Name Description
    NUGET_API_TOKEN NuGet personal API token (
    NUGET_DOTNET_BIN optional. Path to .NET Core. Defaults to dotnet




      - name: nuget

    Rust Crates (crates)

    Publishes a single Rust package or entire workspace on the public crate registry ( If the workspace contains multiple crates, they are published in an order depending on their dependencies.


    "cargo" must be installed and configured on the system.

    Name Description
    CRATES_IO_TOKEN The access token to the account
    CARGO_BIN optional. Path to cargo. Defaults to cargo.


    Option Description
    noDevDeps optional. Strips devDependencies from crates before publishing. This is useful if a workspace crate uses circular dependencies for docs. Requires cargo-hack installed. Defaults to false.


      - name: crates
        noDevDeps: false

    Google Cloud Storage (gcs)

    Uploads artifacts to a bucket in Google Cloud Storage.

    The bucket paths (paths) can be interpolated using Mustache syntax ({{ variable }}). The interpolation context contains the following variables:

    • version: The new project version
    • revision: The SHA revision of the new version


    Google Cloud credentials can be provided using either of the following two environment variables.

    Name Description
    CRAFT_GCS_TARGET_CREDS_PATH Local filesystem path to Google Cloud credentials (service account file)
    CRAFT_GCS_TARGET_CREDS_JSON Full service account file contents, as a JSON string

    If defined, CRAFT_GCS_TARGET_CREDS_JSON will be preferred over CRAFT_GCS_TARGET_CREDS_PATH.

    Note: CRAFT_GCS_TARGET_CREDS_JSON and CRAFT_GCS_TARGET_CREDS_PATH were formerly called CRAFT_GCS_CREDENTIALS_JSON and CRAFT_GCS_CREDENTIALS_PATH, respectively. While those names will continue to work for the foreseeable future, you'll receive a warning encouraging you to switch to the new names.


    Option Description
    bucket The name of the GCS bucket where artifacts are uploaded.
    paths A list of path objects that represent bucket paths.
    paths.path Template-aware bucket path, which can contain {{ version }} and/or {{ revision }}.

        bucket: bucket-name
          - path: release/{{version}}/download
              cacheControl: `public, max-age=3600`
          - path: release/{{revision}}/platform/package

    GitHub Pages (gh-pages)

    Extracts an archive with static assets and pushes them to the specified git branch (gh-pages by default). Thus, it can be used to publish documentation or any other assets to GitHub Pages, so they will be later automatically rendered by GitHub.

    By default, this target will look for an artifact named, extract it, and commit its contents to gh-pages branch.

    WARNING! The destination branch will be completely overwritten by the contents of the archive.




    Option Description
    branch optional The name of the branch to push the changes to. gh-pages by default.
    githubOwner optional GitHub project owner, defaults to the value from the global configuration.
    githubRepo optional GitHub project name, defaults to the value from the global configuration.


      - name: gh-pages
        branch: gh-pages

    Sentry Release Registry (registry)

    The target will update the Sentry release registry repo( with the latest version of the project craft is used with. The release registry repository will be checked out locally, and then the new version file will be created there, along with the necessary symbolic links.

    Two package types are supported: "sdk" and "app". Type "sdk" means that the package is uploaded to one of the public registries (PyPI, NPM, Nuget, etc.), and that the corresponding package directory can be found inside "packages" directory of the release regsitry. Type "app" indicates that the package's version files are located in "apps" directory of the registry.

    It is strongly discouraged to have multiple registry targets in a config as it supports grouping/batching multiple apps and SDKs in a single target.




    Option Description
    apps List of app configs as a dict, keyed by their canonical names (example: app:craft)
    sdks List of sdk configs as a dict, keyed by their canonical names (example: maven:io.sentry:sentry)
    (sdks|apps).urlTemplate optional URL template that will be used to generate download links for "app" package type.
    (sdks|apps).linkPrereleases optional Update package versions even if the release is a preview release, "false" by default.
    (sdks|apps).checksums optional A list of checksums that will be computed for matched files (see includeNames). Every checksum entry is an object with two attributes: algorithm (one of sha256, sha384, and sha512) and format (base64 and hex).
    (sdks|apps).onlyIfPresent optional A file pattern. The target will be executed only when the matched file is found.


      - name: registry
            urlTemplate: '{{version}}/{{file}}'
              - algorithm: sha256
                format: hex

    Cocoapods (cocoapods)

    Pushes a new podspec to the central cocoapods repository. The Podspec is fetched from the Github repository with the revision that is being released. No release assets are required for this target.


    The cocoapods gem must be installed on the system.

    Name Description
    COCOAPODS_TRUNK_TOKEN The access token to the cocoapods account
    COCOAPODS_BIN optional. Path to pod executable.


    Option Description
    specPath Path to the Podspec file in the repository


      - name: cocoapods
        specPath: MyProject.podspec

    Docker (docker)

    Pulls an existing source image tagged with the revision SHA, and then pushed it to a new target tagged with the released version. No release assets are required for this target except for the source image at the provided source image location so it would be a good idea to add a status check that ensures the source image exists, otherwise craft publish will fail at the docker pull step, causing an interrupted publish. This is an issue for other, non-idempotent targets, not for the Docker target.


    docker executable (or something equivalent) must be installed on the system.

    Name Description
    DOCKER_USERNAME The username for the Docker registry.
    DOCKER_PASSWORD The personal access token for the account.
    DOCKER_BIN optional. Path to docker executable.


    Option Description
    source Path to the source Docker image to be pulled
    sourceFormat Format for the source image name. Default: {{{source}}}:{{{revision}}}
    target Path to the target Docker image to be pushed
    targetFormat Format for the target image name. Default: {{{target}}}:{{{version}}}


      - name: docker
        target: getsentry/craft
    # Optional but strongly recommended
      name: github
          - Travis CI - Branch # or whatever builds and pushes your source image

    Ruby Gems Index (gem)

    Pushes a gem Ruby Gems. It also requires you to be logged in with gem login.


    gem must be installed on the system.

    Name Description
    GEM_BIN optional. Path to "gem" executable. Defaults to gem




      - name: gem

    AWS Lambda Layer (aws-lambda-layer)

    Pushes a new Dart or Flutter package to

    Because there is no automated way to login and obtain required tokens, you need to perform a valid release beforehand, for every package that you configure. This will open up your browser and use Google's OAuth to log you in, and generate an appropriate file with stored credentials.

    Based on your environment, you can find this file at either $HOME/.pub-cache/credentials.json or $HOME/Library/Application\ Support/dart/pub-credentials.json for OSX and $HOME/.config/dart/pub-credentials.json for Linux, depending on your setup.

    For this target to work correctly, either dart must be installed on the system or a valid dartCliPath must be provided.


    Name Description
    PUBDEV_ACCESS_TOKEN Value of accessToken obtained from pub-credentials.json
    PUBDEV_REFRESH_TOKEN Value of refreshToken obtained from pub-credentials.json


    Option Description
    dartCliPath optional Path to the Dart CLI. It must be executable by the calling process. Defaults to dart.
    packages optional List of directories to be released, relative to the root. Useful when a single repository contains multiple packages. When skipped, root directory is assumed as the only package.


      - name: pub-dev

    Integrating Your Project with craft

    Here is how you can integrate your GitHub project with craft:

    1. Set up a workflow that builds your assets and runs your tests. Allow building release branches (their names follow release/{VERSION} by default, configurable through releaseBranchPrefix).

            - 'release/**'
    2. Use the official actions/upload-artifact@v2 action to upload your assets. Here is an example config (step) of an archive job:

      - name: Archive Artifacts
        uses: actions/upload-artifact@v2
          name: ${{ github.sha }}
          path: |
            ${{ github.workspace }}/*.tgz
            ${{ github.workspace }}/packages/tracing/build/**
            ${{ github.workspace }}/packages/**/*.tgz

      A few important things to note:

      • The name of the artifacts is very important and needs to be name: ${{ github.sha }}. Craft uses this as a unique id to fetch the artifacts.
      • Keep in mind that this action maintains the folder structure and zips everything together. Craft will download the zip and recursively walk it to find all assets.
    3. Add .craft.yml configuration file to your project

      • List there all the targets you want to publish to
      • Configure additional options (changelog management policy, tag prefix, etc.)
    4. Add a pre-release script to your project.

    5. Get various configuration tokens

    6. Run craft prepare <version> --publish and profit!

    Pre-release (Version-bumping) Script: Conventions

    Among other actions, craft prepare runs an external, project-specific command or script that is responsible for version bumping. By default, this script should be located at: ./scripts/ The command can be configured by specifying the preReleaseCommand configuration option in craft.yml.

    The following requirements are on the script interface and functionality:

    • The script should accept at least two arguments. Craft will pass the old ("from") version and the new ("to") version as the last two arguments, respectively.
    • The script must replace all relevant occurrences of the old version string with the new one.
    • The script must not commit the changes made.
    • The script must not change the state of the git repository (e.g. changing branches)


    ### Example of a version-bumping script for an NPM project.
    ### Located at: ./scripts/
    set -eux
    # Do not tag and commit changes made by "npm version"
    export npm_config_git_tag_version=false
    npm version "${NEW_VERSION}"

    Post-release Script: Conventions

    Among other actions, craft publish runs an external, project-specific command or script that can do things like bumping the development version. By default, this script should be located at: ./scripts/ Unlike the pre-release command, this script is not mandatory so if the file does not exist, craft will report this fact and then move along as usual. This command can be configured by specifying postReleaseCommand configuration option in craft.yml.

    The following requirements are on the script interface and functionality:

    • The script should accept at least two arguments. Craft will pass the old ("from") version and the new ("to") version as the last two arguments, respectively.
    • The script is responsible for any and all git state management as craft will simply exit after running this script as the final step. This means the script is responsible for committing and pushing any changes that it may have made.


    ### Example of a dev-version-bumping script for a Python project
    ### Located at: ./scripts/
    set -eux
    # Ensure master branch
    git checkout master
    # Advance the CalVer release by one-month and add the `.dev0` suffix
    ./scripts/ '' $(date -d "$(echo $NEW_VERSION | sed -e 's/^\([0-9]\{2\}\)\.\([0-9]\{1,2\}\)\.[0-9]\+$/20\1-\2-1/') 1 month" +%y.%-m.0.dev0)
    # Only commit if there are changes, make sure to `pull --rebase` before pushing to avoid conflicts
    git diff --quiet || git commit -anm 'meta: Bump new development version' && git pull --rebase && git push


    Logging Level

    Logging level for craft can be configured via setting the CRAFT_LOG_LEVEL environment variable or using the --log-level CLI flag.

    Accepted values are: Fatal, Error, Warn, Log, Info, Success, Debug, Trace, Silent, Verbose

    Dry-run Mode

    Dry-run mode can be enabled via setting the CRAFT_DRY_RUN environment variable to any truthy value (any value other than undefined, null, "", 0, false, and no). One may also use the --dry-run CLI flag.

    In dry-run mode no destructive actions will be performed (creating remote branches, pushing tags, committing files, etc.)

    Sentry Support

    Errors you encounter while using Craft can be sent to Sentry. To use this feature, add CRAFT_SENTRY_DSN variable to your environment (or "craft" configuration file) that contains a Sentry project's DSN.

    For example:

    export CRAFT_SENTRY_DSN=''


    craft obviously uses craft for preparing and publishing new releases!

    Did you mean recursion?
