**Enable automatic updates for diagram-design by ensuring the GitHub Actions workflow in [`.github/workflows/pages.yml`](https://github.com/cathrynlavery/diagram-design/blob/main/.github/workflows/pages.yml) is active and pushing changes to the `main` branch; optionally add Dependabot for dependency updates.**

The **diagram-design** repository by **cathrynlavery** provides a ready-made automation pipeline that rebuilds and deploys your diagram gallery whenever you make changes. This article explains exactly how this system works and how to activate it for your own fork or clone.

## How Automatic Updates Work in Diagram-Design

The repository uses **GitHub Actions** to handle continuous deployment. The workflow file at [`.github/workflows/pages.yml`](https://github.com/cathrynlavery/diagram-design/blob/main/.github/workflows/pages.yml) defines two triggers:

1. **Push events** to the `main` branch — automatically rebuilds on every commit
2. **Manual trigger** via `workflow_dispatch` — allows on-demand rebuilds through the GitHub UI

When triggered, the workflow regenerates static assets from the source files in `skills/diagram-design/assets/` and publishes them to **GitHub Pages**.

---

## Step 1: Verify Repository Access and Workflow Status

Before automatic updates can function, you need **write access** to a repository where the workflow can run.

- **Fork** the repository to your own GitHub account, or
- **Clone** and push to a repository where you have admin permissions

Open [`.github/workflows/pages.yml`](https://github.com/cathrynlavery/diagram-design/blob/main/.github/workflows/pages.yml) to confirm the workflow exists:

```yaml

# .github/workflows/pages.yml – triggers defined here

on:
  push:
    branches: [ main ]
  workflow_dispatch:   # enables manual "Run workflow" button

```

The `push` trigger on `main` is the key mechanism that enables automatic updates for diagram-design.

---

## Step 2: Trigger an Automatic Update

Any commit to `main` initiates the rebuild process. Edit any diagram source file under `skills/diagram-design/` or even a documentation file:

```bash
git checkout main
echo "<!-- triggering rebuild -->" >> README.md
git add README.md
git commit -m "Trigger auto-update of gallery"
git push origin main

```

The workflow will appear in your repository's **Actions** tab within seconds, showing the build and deployment progress.

---

## Step 3: Verify Deployment on GitHub Pages

Once the workflow completes successfully, your updated gallery is live at:

```

https://<your-username>.github.io/diagram-design/

```

The static assets generated in `skills/diagram-design/assets/` are now serving the latest version of your diagrams.

---

## Optional: Enable Dependency Updates with Dependabot

For **dependency-level automatic updates** (keeping tools like Playwright or Mermaid current), add a Dependabot configuration:

```yaml

# .github/dependabot.yml

version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"

```

Commit this file to `main` and Dependabot will automatically open pull requests when new versions of your dependencies become available.

---

## Key Files Controlling Automatic Updates

| File | Purpose |
|------|---------|
| [`.github/workflows/pages.yml`](https://github.com/cathrynlavery/diagram-design/blob/main/.github/workflows/pages.yml) | Defines the CI/CD pipeline that enables automatic updates for diagram-design |
| `skills/diagram-design/assets/` | Destination for generated HTML/SVG files served by GitHub Pages |
| [`README.md`](https://github.com/cathrynlavery/diagram-design/blob/main/README.md) | Safe file to edit for triggering test deployments |

---

## Manual Rebuild Without Code Changes

If you need to force a rebuild without modifying source files, use GitHub's interface:

1. Navigate to **Actions** → **Pages** workflow
2. Click **Run workflow** → select `main` branch → **Run**

This executes the same deployment pipeline without requiring a commit.

---

## Summary

- **Automatic updates** rely on the pre-configured GitHub Actions workflow at [`.github/workflows/pages.yml`](https://github.com/cathrynlavery/diagram-design/blob/main/.github/workflows/pages.yml)
- **Push any change to `main`** to trigger a full rebuild and deployment cycle
- **GitHub Pages hosts** the output from `skills/diagram-design/assets/` automatically
- **Dependabot** provides optional automatic updates for build dependencies
- **Manual triggers** via `workflow_dispatch` allow deployment on demand

## Frequently Asked Questions

### What triggers automatic updates in diagram-design?

Any push to the `main` branch triggers the workflow defined in [`.github/workflows/pages.yml`](https://github.com/cathrynlavery/diagram-design/blob/main/.github/workflows/pages.yml). This includes commits that modify diagram sources, documentation, or even just a whitespace change.

### Can I enable automatic updates on a branch other than main?

You can modify the workflow's `on.push.branches` array in [`.github/workflows/pages.yml`](https://github.com/cathrynlavery/diagram-design/blob/main/.github/workflows/pages.yml) to watch additional branches, but GitHub Pages typically deploys from one designated branch only.

### Does diagram-design support scheduled automatic updates?

The repository does not include `schedule` triggers by default. You can add a `schedule` event to the workflow's `on` section if you need periodic rebuilds regardless of code changes.

### How do I check if automatic updates are working correctly?

Push a visible change (like editing [`README.md`](https://github.com/cathrynlavery/diagram-design/blob/main/README.md)), then monitor the **Actions** tab for a green checkmark. The updated content should appear at your GitHub Pages URL within 1-2 minutes of workflow completion.
