Dev Tunnel

Full development environment setup with Cloudflare tunnel and CLI authentication. Useful for webhook testing.

Note: Since issue #1726, the web app automatically starts a Cloudflare tunnel when running pnpm dev. This operation is useful when you need the complete setup including CLI authentication.

What It Does

• Installs dependencies and builds project
• Starts dev server (tunnel is now automatic for web app)
• Installs E2E dependencies and Playwright
• Installs and authenticates CLI globally

Workflow

Step 1: Install Dependencies

PROJECT_ROOT=$(git rev-parse --show-toplevel)
cd "$PROJECT_ROOT/turbo" && pnpm install

Step 2: Build Project

PROJECT_ROOT=$(git rev-parse --show-toplevel)
cd "$PROJECT_ROOT/turbo" && pnpm build

Step 3: Start Dev Server and Runner

Use Bash tool with run_in_background: true for both commands in parallel (two separate Bash calls in the same message):

Dev server (use tee to persist logs for /dev-logs after context compaction):

PROJECT_ROOT=$(git rev-parse --show-toplevel)
cd "$PROJECT_ROOT/turbo" && pnpm dev 2>&1 | tee "$PROJECT_ROOT/turbo/.dev-server.log"

Runner:

PROJECT_ROOT=$(git rev-parse --show-toplevel)
cd "$PROJECT_ROOT/turbo" && pnpm runner

Both return a task_id for monitoring. The web app will automatically start a Cloudflare tunnel. The runner takes several minutes to initialize but doesn't block the app — only chat/agent features need it.

Step 4: Wait for Tunnel URL

Use TaskOutput with the task_id from Step 3 to monitor the background task output. Look for:

• [tunnel] Tunnel URL: followed by the URL
• Ready in (Next.js ready message)

Poll TaskOutput every few seconds until the tunnel URL appears (up to ~60 seconds). Extract the tunnel URL (format: https://*.trycloudflare.com).

If the tunnel URL does not appear within ~60 seconds, report the failure and let the user investigate.

Step 5: Export VM0_API_URL

export VM0_API_URL=<tunnel-url>

Step 6: Install E2E Dependencies

PROJECT_ROOT=$(git rev-parse --show-toplevel)
cd "$PROJECT_ROOT/e2e" && pnpm install

Step 7: Install Playwright Browser

PROJECT_ROOT=$(git rev-parse --show-toplevel)
cd "$PROJECT_ROOT/e2e" && npx playwright install chromium

Step 8: Install CLI Globally

PROJECT_ROOT=$(git rev-parse --show-toplevel)
cd "$PROJECT_ROOT/turbo/apps/cli" && pnpm link --global

Step 9: Run CLI Authentication

Read Clerk credentials from turbo/apps/web/.env.local:

• NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY → CLERK_PUBLISHABLE_KEY
• CLERK_SECRET_KEY → CLERK_SECRET_KEY

Then run:

PROJECT_ROOT=$(git rev-parse --show-toplevel)
cd "$PROJECT_ROOT/e2e" && \
CLERK_PUBLISHABLE_KEY=<publishable-key> \
CLERK_SECRET_KEY=<secret-key> \
npx tsx cli-auth-automation.ts $(printenv VM0_API_URL)

Step 10: Verify Authentication

cat ~/.vm0/config.json

Step 11: Display Results

✅ Dev server with tunnel started!
🔧 Runner deployment started in background (takes several minutes)

Local:   http://localhost:3000
Tunnel:  <tunnel-url>

VM0_API_URL exported to: <tunnel-url>

✅ CLI authentication successful!
Auth token saved to: ~/.vm0/config.json

The app is usable now. Chat/agent features will become available once the runner finishes initializing.

Use `/dev-stop` to stop the server.

Technical Details

The web app's dev script (turbo/apps/web/scripts/dev.sh):

• Starts a Cloudflare tunnel using cloudflared
• Exposes localhost:3000 to the internet
• Sets VM0_API_URL environment variable
• Starts Next.js dev server with Turbopack

Error Handling

If tunnel fails to start:

• Check if cloudflared is installed
• Check tunnel logs: tail -f /tmp/cloudflared-dev.log

If authentication fails:

• Check dev server logs with /dev-logs
• Verify Clerk credentials in turbo/apps/web/.env.local
• Ensure Playwright browser is installed
