Send messages to Slack from GitHub Actions.

This action sends message to Slack during your GitHub Actions workflow. It takes a minimalist approach, showing a handful of metadata options like repository, branch & commit. You can optionally update message in-place to reduce noise in your Slack channel.

## Usage

```yml

- uses: someimportantcompany/github-actions-slack-message@v1

  with:

    channel: ${{ env.SLACK_CHANNEL }}

    bot-token: ${{ secrets.SLACK_BOT_TOKEN }}

    text: Firing a bot-token message

- uses: someimportantcompany/github-actions-slack-message@v1

  with:

    webhook-url: ${{ secrets.SLACK_WEBHOOK_URL }}

    text: Firing a webhook message

```

- Including a `color` wraps your message in a (soon to be deprecated) `attachments` block.

- Links refer back to your repository, the branch & the commit.

### Updating an existing message

If you are planning to send multiple Slack messages per invocation, and you'd prefer to update a single message instead of posting multiple messages, you can pass the first Slack message's `message-id` to future calls, thus updating in place. **A `bot-token` is required to update messages.**

```yml

- uses: someimportantcompany/github-actions-slack-message@v1

  id: slack

  with:

    channel: ${{ env.SLACK_CHANNEL }}

    bot-token: ${{ secrets.SLACK_BOT_TOKEN }}

    text: Deployment started

- run: npm run deploy

- uses: someimportantcompany/github-actions-slack-message@v1

  with:

    channel: ${{ env.SLACK_CHANNEL }}

    bot-token: ${{ secrets.SLACK_BOT_TOKEN }}

    text: Deployment finished

    color: good

    message-id: ${{ steps.slack.outputs.message-id }}

```

### Additional colors

Alongside the Slack default colors `good`, `warning` & `danger`, this action supports some additional colors for convenience:

| Key | Value |

| ---- | ---- |

| `success` | `good` |

| `failure` | `danger` |

| `info` | ![#17a2b8](https://via.placeholder.com/25/17a2b8/000000?text=+) |

| `gray` | ![#B6B6B6](https://via.placeholder.com/25/B6B6B6/000000?text=+) |

| `grey` | ![#B6B6B6](https://via.placeholder.com/25/B6B6B6/000000?text=+) |

| `orange` | ![#FF4500](https://via.placeholder.com/25/FF4500/000000?text=+) |

| `purple` | ![#9400D3](https://via.placeholder.com/25/9400D3/000000?text=+) |

```yml

- uses: someimportantcompany/github-actions-slack-message@v1

  with:

    webhook-url: ${{ secrets.SLACK_WEBHOOK_URL }}

    text: Build finished

    color: good # Slack already-supported color

- uses: someimportantcompany/github-actions-slack-message@v1

  with:

    webhook-url: ${{ secrets.SLACK_WEBHOOK_URL }}

    text: Build failed

    color: failed # Aliased color

```

### Running if-success or if-failure

Using built-in Actions conditionals, you can send an error if the job succeeded or failed.

```yml

- uses: someimportantcompany/github-actions-slack-message@v1

  if: success()

  with:

    webhook-url: ${{ secrets.SLACK_WEBHOOK_URL }}

    text: Build passed

    color: success

- uses: someimportantcompany/github-actions-slack-message@v1

  if: failure()

  with:

    webhook-url: ${{ secrets.SLACK_WEBHOOK_URL }}

    text: Build failed

    color: failure

```
