This plugin is using an incoming webhook to notify a teams channel. Here is some documentation to create one.

Usage

// .releaserc.json
{
  "branches": ["main"],
  "plugins": [
    "@semantic-release/commit-analyzer",
    "@semantic-release/release-notes-generator",
    ["semantic-release-ms-teams", {
      "webhookUrl": "...",
      "title": "A new version has been released",
      "imageUrl": "http://...",
      "showContributors": false,
      "notifyInDryRun": true,
    }]
  ]
}

Variable	Details	Description
webhookUrl or TEAMS_WEBHOOK_URL	required, url	The incoming webhook url of the channel to publish release notes to.
webhookUrlDryRun or TEAMS_WEBHOOK_URL_DRYRUN	optional, url	Similar to webhookUrl or TEAMS_WEBHOOK_URL, but will be used in dryRun mode. Default: webhookUrl or TEAMS_WEBHOOK_URL
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
notifyInDryRun	optional, boolean	Whether or not the release notes will be send to Teams when semantic-release runs in dry-run mode. Default: true

Notes

• webhookUrl is a property of the config object in .releaserc.json, and, TEAMS_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 teams channel, you will want to use the TEAMS_WEBHOOK_URL instead.

• When in dry-run mode, here are the order of considered urls: webhookUrlDryRun, TEAMS_WEBHOOK_URL_DRY_RUN, webhookUrl, TEAMS_WEBHOOK_URL

• 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 disabled (mainly for privacy reasons).

• 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.

Development

Here are some steps to test the plugin locally:

• checkout the source code:

  git clone [e-mail]:sragot/semantic-release-ms-teams.git
  cd semantic-release-ms-teams
  npm install

• create a personal access token in github, then export GH_TOKEN=...
• run semantic-release locally safely:

  npm link
  npm link semantic-release-ms-teams
  npm run release -- --dry-run --no-ci

Dependencies

• remark: Markdown to JSON
• mdast-util-to-markdown: JSON to Markdown
• node-fetch-commonjs: As fetch isn't in NodeJS 16, and semantic-release doesn't support ES modules. These 2 assertions are subject to evolutions.

Greatly inspired by semantic-release-slack-bot ... Thanks ;)
