Upgrade Slack GHA

If you like having your GitHub Actions workflows post messages to Slack, well, things just got a lot easier. Version 2 of slack-github-action has been released, and it makes your workflow file so much nicer because it supports YAML! Here is what it looks like. BEFORE: - name: Post to Slack uses: slackapi/slack-github-action@v1 env: SLACK_BOT_TOKEN: ${{ secrets.SLACK_BOT_TOKEN }} with: channel-id: "C3P0ANDR2D2" payload: | { "blocks": [ { "type": "section", "text": { "type": "mrkdwn", "text": "My message goes here" } } ] } AFTER: - name: Post to Slack uses: slackapi/slack-github-action@v2 with: method: chat.postMessage token: ${{ secrets.SLACK_BOT_TOKEN }} payload: | channel: "C3P0ANDR2D2" blocks: - type: section text: type: mrkdwn text: "My message goes here" So much prettier and easier to read/maintain. Note, you will have to shuffle some things around (like where the token is specified), and be explicit about the method you are using. Here is an example of an update message - name: Update Slack with success if: ${{ success() }} uses: slackapi/slack-github-action@v2 with: method: chat.update token: ${{ secrets.SLACK_BOT_TOKEN }} payload: | channel: "C3P0ANDR2D2" ts: ${{ steps.slack.outputs.ts }} blocks: - type: section text: type: mrkdwn text: "My updated test" fields: - type: mrkdwn text: "My updated field" I used Cursor to help me do all of the conversion from JSON to YAML, so this wasn't too painful of a change. Happy Coding!

If you like having your GitHub Actions workflows post messages to Slack, well, things just got a lot easier. Version 2 of slack-github-action has been released, and it makes your workflow file so much nicer because it supports YAML! Here is what it looks like.

BEFORE:

      - name: Post to Slack
        uses: slackapi/slack-github-action@v1
        env:
          SLACK_BOT_TOKEN: ${{ secrets.SLACK_BOT_TOKEN }}
        with:
          channel-id: "C3P0ANDR2D2"
          payload: |
            {
              "blocks": [
                {
                  "type": "section",
                  "text": {
                    "type": "mrkdwn",
                    "text": "My message goes here"
                  }
                }
              ]
            }

AFTER:

      - name: Post to Slack
        uses: slackapi/slack-github-action@v2
        with:
          method: chat.postMessage
          token: ${{ secrets.SLACK_BOT_TOKEN }}
          payload: |
            channel: "C3P0ANDR2D2"
            blocks:
              - type: section
                text:
                  type: mrkdwn
                  text: "My message goes here"

So much prettier and easier to read/maintain.

Note, you will have to shuffle some things around (like where the token is specified), and be explicit about the method you are using.

Here is an example of an update message

      - name: Update Slack with success
        if: ${{ success() }}
        uses: slackapi/slack-github-action@v2
        with:
          method: chat.update
          token: ${{ secrets.SLACK_BOT_TOKEN }}
          payload: |
            channel: "C3P0ANDR2D2"
            ts: ${{ steps.slack.outputs.ts }}
            blocks:
              - type: section
                text:
                  type: mrkdwn
                  text: "My updated test"
                fields:
                  - type: mrkdwn
                    text: "My updated field"

I used Cursor to help me do all of the conversion from JSON to YAML, so this wasn't too painful of a change.

Happy Coding!
