A plugin for semantic-release which publish release notes in a Google Chat
npm install semantic-release-google-chatsemantic-release plugin to send release notes to a Google Chat channel when the release succeeds.
| Step | Description |
| ------------------ | ------------------------------------------------------------- |
| verifyConditions | Check the webhookUrl option or GOOGLE_CHAT_WEBHOOK_URL variable |
| success | Send a Google Chat message to notify of a new release. |
``sh`
npm install semantic-release-google-chat --save-devor
yarn add semantic-release-google-chat --dev
This plugin is using an _incoming webhook_ to notify a Google Chat space. Here is
some documentation to create one.

"@semantic-release/commit-analyzer",

| Variable | Details | Description |
| --- | --- | --- |
| webhookUrl or GOOGLE_CHAT_WEBHOOK_URL | required, url | The incoming webhook url of the channel to publish release notes to. |title
| | _optional_, text | The title of the message. Default: _A new version has been released_ |imageUrl
| | _optional_, url | An image displayed in the message, next to the title. The image must be less than 200x200. |showContributors
| | _optional_, boolean | Whether or not the contributors should be displayed in the message. Default: true |
is a property of the config object in .releaserc.json, and,
GOOGLE_CHAT_WEBHOOK_URL is an environment variable. The config object can be
useful to try the plugin, but most of the time, production environments
prefers environment variables. You can use both, but not in the same time as
it does not make sense. If you do define both, the config object overrides
the environment variable.
- IMPORTANT: The webhookUrl variable you can use within your plugin
configuration is meant to be used only for test purposes. Because you don't
want to publicly publish this url and do let the world know a way to send
messages to your Google Chat channel, you will want to use the GOOGLE_CHAT_WEBHOOK_URL
instead.- The default value for
imageUrl is 
_https://upload.wikimedia.org/wikipedia/commons/thumb/4/4e/Gitlab_meaningful_logo.svg/144px-Gitlab_meaningful_logo.svg.png_- The list of Contributors is built using the email associated with the commits
(only the part before the "@" is kept). This list can be disable (mainly for
privacy reasons).
- The message is sent to Google Chat during the
success step which is silenced in
dryRun mode.- The official
@semantic-release/git plugin may cause a second message to be
sent (because the plugin potentially adds a commit on the current branch, to
save changes in files like package.json, package-lock.json, CHANGELOG.md).
In order to prevent that, an environment variable (HAS_PREVIOUS_SEM_REL_EXECUTION)
is set to true after the first message, then this plugin won't send any other
message, as long as the plugin is part of the config.Screenshots
Development
Here are some steps to test the plugin locally:
- checkout the source code:
`sh
git clone git@github.com:jontey/semantic-release-google-chat.git
cd semantic-release-google-chat
npm install
`
- add a .releaserc.json file at the project's root, copy the code from the
Usage section in this new file using the webhookUrl property, and
add the following properties in the object:
`
"ci": false,
"dryRun": true,
`
- open index.js and replace module.exports = { verifyConditions, success }; by module.exports = { verifyConditions, generateNotes: success }; to allow the publication within the dryRun mode
- run semantic-release locally safely:
`sh
npm link
npm link semantic-release-google-chat
./node_modules/.bin/semantic-release
