What's Changed

Alongside the breaking changes of @v3.0.0 and a new technique to run Slack CLI commands, we tried the wrong name to publish to the GitHub Marketplace 🐙 This action is now noted as The Slack GitHub Action in listings 🎶 ✨

v3.0.0: Slack GitHub Action v3.0.0

Compare Source

The @v3.0.0 release had a hiccup on publish and we recommend using @​v3.0.1 or a more recent version when updating! Oops!

🎽 Running Slack CLI commands and the active Node runtime, both included in this release 👟 ✨

⚠️ Breaking change: Node.js 24 the runtime

This major version updates the GitHub Actions required runtime to Node.js 24. Most GitHub-hosted runners already include this, but self-hosted runners may need to be updated ahead of planned deprecations of Node 20 on GitHub Actions runners.

📺 Enhancement: Run Slack CLI commands

This release introduces a new technique for running Slack CLI commands directly in GitHub Actions workflows. Use this to install the latest version (or a specific one) of the CLI and execute commands like deploy for merges to main, manifest validate with tests, and other commands.

Gather a token using the following CLI command to store with repo secrets, then get started with an example below:

$ slack auth token
🧪 Validate an app manifest on pull requests

Check that your app manifest is valid before merging changes:

🔗 https://docs.slack.dev/tools/slack-github-action/sending-techniques/running-slack-cli-commands/validate-a-manifest

- name: Validate the manifest
  uses: slackapi/slack-github-action/cli@v3.0.0
  with:
    command: "manifest validate --app ${{ vars.SLACK_APP_ID }}"
    token: ${{ secrets.SLACK_SERVICE_TOKEN }}
🚀 Deploy your app on push to main

Automate deployments whenever changes land on your main branch:

🔗 https://docs.slack.dev/tools/slack-github-action/sending-techniques/running-slack-cli-commands/deploy-an-app

- name: Deploy the app
  uses: slackapi/slack-github-action/cli@v3.0.0
  with:
    command: "deploy --app ${{ vars.SLACK_APP_ID }} --force"
    token: ${{ secrets.SLACK_SERVICE_TOKEN }}

Any Slack CLI command can be passed through the command option without the "slack" prefix 🍀

The token input accepts a service token for authentication. You can gather this token by running slack auth token with the Slack CLI and storing the value as a repository secret.

The latest Slack CLI version is used by default, but a specific one can be set with the version input.

🏆 Huge thanks to @​ewanek1 for explorations and prototypes toward the scripted CLI technique!
