semantic-release-export-data

semantic-release plugin to export variables like the next release version. Also works in --dry-run mode.

Step	Description
verifyConditions	Set new-release-published as false (will be set later as true if a new release is published)
generateNotes	If a new release is published, this will set new-release-published as true and other variables

Install

npm install --save-dev semantic-release-export-data

OR

yarn add -D semantic-release-export-data

Usage

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

{
  "plugins": ["semantic-release-export-data"]
}

Outputs

Currently, the plugin exports the following GitHub Actions's outputs:

Output	Description
new-release-published	Whether a new release was published. The return value is in the form of a string. (true or false)
new-release-version	If a new release was published, the version of the new release. (e.g. 1.3.0)

Why?

Because of https://github.com/felipecrs/semantic-release-vsce/issues/189#issuecomment-1115021771 and https://github.com/semantic-release/semantic-release/issues/1647.

Thanks

Inspired by the awesome semantic-release-action by @cycjimmy, although this provides the ability of running semantic-release in --dry-run mode, so you don't have to cut a release unless everything else is done.
