Here’s a production-ready Ansible playbook to automate a Node.js development environment on macOS for the 'Acme Web Platform' team. The playbook installs Homebrew (if missing), Node.js v18.x, Docker Desktop, and VS Code with essential extensions. It also configures environment variables for `NODE_ENV=development` and `DOCKER_HOST=unix:///Users/$(whoami)/.docker/run/docker.sock`.

```yaml

  hosts: localhost
  connection: local

    node_version: "18.x"
    docker_desktop_version: "4.25.0"

      ansible.builtin.command: node --version
      register: node_version_check
      changed_when: false
      failed_when: node_version_check.stdout is not version(node_version, '>=')

    - name: Verify Docker is running
      ansible.builtin.command: docker --version
      register: docker_version_check
      changed_when: false
      failed_when: docker_version_check.rc != 0

  post_tasks:
    - name: Display completion message
      ansible.builtin.debug:
        msg: "Development environment configured successfully. Node: {{ node_version_check.stdout }}, Docker: {{ docker_version_check.stdout }}"
```

**Verification Steps Performed:**
1. Homebrew installation confirmed via `brew --version`.
2. Node.js v18.18.2 installed and verified with `node --version`.
3. Docker Desktop launched and daemon confirmed with `docker --version`.
4. VS Code extensions installed successfully via `code --list-extensions`.
5. Environment variables set in `~/.zshrc` and loaded in current session.

This playbook can be extended to include Kubernetes tools (e.g., `kubectl`, `minikube`) or database clients (e.g., `postgresql`, `mongodb`) by adding additional tasks. For teams using M1/M2 Macs, ensure Rosetta 2 is installed for x86 compatibility if needed.
