# Bitbucket Pipelines: PR Preview Environments

Deploy preview environments for pull requests and clean up when they close.

```yaml title="bitbucket-pipelines.yml"
image: node:20

pipelines:
  pull-requests:
    "**":
      - step:
          name: Deploy Preview
          script:
            - npm install
            - npx zuplo deploy --api-key "$ZUPLO_API_KEY" 2>&1 | tee
              ./DEPLOYMENT_STDOUT
            - echo "DEPLOYMENT_URL=$(grep -oP 'Deployed to \K(https://[^ ]+)'
              ./DEPLOYMENT_STDOUT)" >> deployment.env
          artifacts:
            - deployment.env

      - step:
          name: Run Tests
          script:
            - source deployment.env
            - npm install
            - npx zuplo test --endpoint "$DEPLOYMENT_URL"

      - step:
          name: Cleanup Preview
          script:
            - source deployment.env
            - npm install
            - npx zuplo delete --url "$DEPLOYMENT_URL" --api-key
              "$ZUPLO_API_KEY" --wait
```

The cleanup step runs after tests complete, deleting the preview environment.
