@semantic-release/exec

semantic-release plugin to execute custom shell commands.

Step	Description
verifyConditions	Execute a shell command to verify if the release should happen.
analyzeCommits	Execute a shell command to determine the type of release.
verifyRelease	Execute a shell command to verifying a release that was determined before and is about to be published.
generateNotes	Execute a shell command to generate the release note.
prepare	Execute a shell command to prepare the release.
publish	Execute a shell command to publish the release.
success	Execute a shell command to notify of a new release.
fail	Execute a shell command to notify of a failed release.

Install

$ npm install @semantic-release/exec -D

Usage

The plugin can be configured in the semantic-release configuration file:

{
  "plugins": [
    "@semantic-release/commit-analyzer",
    "@semantic-release/release-notes-generator",
    [
      "@semantic-release/exec",
      {
        "verifyConditionsCmd": "./verify.sh",
        "publishCmd": "./publish.sh ${nextRelease.version} ${branch.name} ${commits.length} ${Date.now()}"
      }
    ]
  ]
}

With this example:

• the shell command ./verify.sh will be executed on the verify conditions step
• the shell command ./publish.sh 1.0.0 master 3 870668040000 (for the release of version 1.0.0 from branch master with 3 commits on August 4th, 1997 at 2:14 AM) will be executed on the publish step

Note: it's required to define a plugin for the analyze commits step. If no analyzeCommitsCmd is defined the plugin @semantic-release/commit-analyzer must be defined in the plugins list.

Configuration

Options

Options	Description
verifyConditionsCmd	The shell command to execute during the verify condition step. See verifyConditionsCmd.
analyzeCommitsCmd	The shell command to execute during the analyze commits step. See analyzeCommitsCmd.
verifyReleaseCmd	The shell command to execute during the verify release step. See verifyReleaseCmd.
generateNotesCmd	The shell command to execute during the generate notes step. See generateNotesCmd.
prepareCmd	The shell command to execute during the prepare step. See prepareCmd.
addChannelCmd	The shell command to execute during the add channel step. See addChannelCmd.
publishCmd	The shell command to execute during the publish step. See publishCmd.
successCmd	The shell command to execute during the success step. See successCmd.
failCmd	The shell command to execute during the fail step. See failCmd.
shell	The shell to use to run the command. See execa#shell.
execCwd	The path to use as current working directory when executing the shell commands. This path is relative to the path from which semantic-release is running. For example if semantic-release runs from /my-project and execCwd is set to buildScripts then the shell command will be executed from /my-project/buildScripts

Each shell command is generated with Lodash template. All the context object keys passed to semantic-release plugins are available as template options.

exit code	Any non 0 code is considered as an unexpected error and will stop the semantic-release execution with an error.
stdout	Only the release type (major, minor or patch etc..) can be written to stdout. If no release has to be done the command must not write to stdout.
stderr	Can be used for logging.

verifyReleaseCmd

Command property	Description
exit code	0 if the verification is successful, or any other exit code otherwise.
stdout	Only the reason for the verification to fail can be written to stdout.
stderr	Can be used for logging.

generateNotesCmd

Command property	Description
exit code	Any non 0 code is considered as an unexpected error and will stop the semantic-release execution with an error.
stdout	Only the release note must be written to stdout.
stderr	Can be used for logging.

prepareCmd

Command property	Description
