title: Scopes with Turborepo
description: Configure merge queue scopes using Turborepo's dependency graph awareness.
---

If you're using monorepo tools like Turborepo that have built-in
dependency graph analysis, you can leverage their affected project detection instead of using file
patterns. This approach is often more accurate because these tools understand your project's
dependency relationships.

## Configuring Manual Scopes

To use the manual scopes mechanism, configure Mergify to expect scopes from your CI system:

```yaml
scopes:
  source:
    manual:

queue_rules:
  - name: default
    batch_size: 5
```

## Detecting Scopes with Turborepo

Use the `turbo run build --dry=json` command to determine affected projects
and upload them to Mergify.

### GitHub Actions

```yaml
name: Detect Scopes
on:
  pull_request:

jobs:
  detect-scopes:
    runs-on: ubuntu-24.04
    steps:
      - uses: actions/checkout@v5

      - name: Get git refs
        id: refs
        uses: Mergifyio/gha-mergify-ci@@@GHA_MERGIFY_CI_VERSION@@
        with:
          action: scopes-git-refs

      - name: Get scopes
        id: scopes
        env:
          HEAD: ${{ steps.refs.outputs.head }}
          BASE: ${{ steps.refs.outputs.base }}
        run: |
          scopes=$(npx turbo run build --dry=json --filter="[$BASE...$HEAD]" | jq -r '.packages | join(",")')
          echo "scopes=$scopes" >> "$GITHUB_OUTPUT"

      - name: Scopes upload
        uses: Mergifyio/gha-mergify-ci@@@GHA_MERGIFY_CI_VERSION@@
        with:
          action: scopes-upload
          token: ${{ secrets.MERGIFY_TOKEN }}
          scopes: ${{ steps.scopes.outputs.scopes }}
```

### Buildkite

Using the
[`mergifyio/mergify-ci`](https://github.com/Mergifyio/mergify-ci-buildkite-plugin)
Buildkite plugin, a first step resolves the merge-queue-aware base and head
SHAs and exposes them as meta-data, while a second step computes the affected
projects with `turbo run build --dry=json` and uploads them to Mergify:

```yaml
steps:
  - label: ":mag: Get git refs"
    key: git-refs
    plugins:
      - mergifyio/mergify-ci#@@BUILDKITE_PLUGIN_VERSION@@:
          action: scopes-git-refs

  - label: ":mag: Detect and upload scopes"
    depends_on: git-refs
    command: |
      BASE=$(buildkite-agent meta-data get "mergify-ci.base")
      HEAD=$(buildkite-agent meta-data get "mergify-ci.head")
      SCOPES=$(npx turbo run build --dry=json --filter="[$BASE...$HEAD]" | jq -r '.packages | join(",")')
      buildkite-agent meta-data set "mergify-ci.scopes" "$SCOPES"
    plugins:
      - mergifyio/mergify-ci#@@BUILDKITE_PLUGIN_VERSION@@:
          action: scopes-upload
          token: "${MERGIFY_TOKEN}"
```

### Any CI (Mergify CLI)

<ScopesDetection
  command={String.raw`npx turbo run build --dry=json --filter="[$BASE...$HEAD]" \
  | jq '{scopes: .packages}' > scopes.json`}
/>
