Plugins
Each release step is implemented by configurable plugins. This allows for support of different commit message formats, release note generators and publishing platforms.
A plugin is a npm module that can implement one or more of the following steps:
Step | Required | Description |
| No | Responsible for verifying conditions necessary to proceed with the release: configuration is correct, authentication token are valid, etc... |
| Yes | Responsible for determining the type of the next release ( |
| No | Responsible for verifying the parameters (version, type, dist-tag etc...) of the release that is about to be published. |
| No | Responsible for generating the content of the release note. If multiple plugins with a |
| No | Responsible for preparing the release, for example creating or updating files such as |
| No | Responsible for publishing the release. |
| No | Responsible for adding a release channel (e.g. adding an npm dist-tag to a release). |
| No | Responsible for notifying of a new release. |
| No | Responsible for notifying of a failed release. |
Release steps will run in that order. At each step, semantic-release will run every plugin in the plugins
array, as long as the plugin implements the step.
Note: If no plugin with a analyzeCommits
step is defined @semantic-release/commit-analyzer
will be used.
Plugins installation
Default plugins
These four plugins are already part of semantic-release and are listed in order of execution. They do not have to be installed separately:
Additional plugins
Additional plugins have to be installed via npm:
Plugins declaration and execution order
Each plugin must be configured with the plugins
options by specifying the list of plugins by npm module name.
Note: If the plugins
option is defined, it overrides the default plugin list, rather than merging with it.
For each release step the plugins that implement that step will be executed in the order in which they are defined.
With this configuration semantic-release will:
execute the
verifyConditions
implementation of@semantic-release/npm
then@semantic-release/git
execute the
analyzeCommits
implementation of@semantic-release/commit-analyzer
execute the
generateNotes
implementation of@semantic-release/release-notes-generator
execute the
prepare
implementation of@semantic-release/npm
then@semantic-release/git
execute the
publish
implementation of@semantic-release/npm
Order is first determined by release steps (such as verifyConditions
→ anayzeCommits
). At each release step, plugins are executed in the order in which they are defined.
Plugin options configuration
A plugin configuration can be specified by wrapping the name and an options object in an array. Options configured this way will be passed only to that specific plugin.
Global plugin configuration can be defined at the root of the semantic-release configuration object. Options configured this way will be passed to all plugins.
With this configuration:
All plugins will receive the
preset
option, which will be used by both@semantic-release/commit-analyzer
and@semantic-release/release-notes-generator
(and ignored by@semantic-release/github
and@semantic-release/git
)The
@semantic-release/github
plugin will receive theassets
options (@semantic-release/git
will not receive it and therefore will use it's default value for that option)
