Demo Site Management

Demo Site Management

Manage the Umbraco.AI demo site with automatic port discovery via named pipes.

Command: $ARGUMENTS

Execute the requested demo site operation.

Available commands

• start: Start demo site with DemoSite-Claude profile on dynamic port
• stop: Stop the running demo site
• generate-client: Generate OpenAPI clients (starts site if needed)
• status: Check if site is running and show port/pipe info
• restart: Stop and restart the demo site
• open: Open the demo site in default browser (discovers port automatically)

Current Environment

• Working directory: !pwd
• Git branch: !git branch --show-current 2>/dev/null || echo "not in git repo"
• Background tasks: !echo "Check with /tasks command for active background tasks"

Implementation Guide

For "start"

1. Check if already running using multi-method detection:
   • Try querying site address endpoint via named pipe (see "Query site address via named pipe" section)
   • Check if background tasks exist with "DemoSite" in description
   • If running, report and exit
2. Detect demo site path:
   • Read Directory.Packages.props and extract the major from the Umbraco.Cms.Core lower bound (e.g. [18.0.0, …) → 18)
   • Demo site path: demos/v{major}/Umbraco.AI.DemoSite
3. If not running, start in background: cd demos/v{major}/Umbraco.AI.DemoSite && dotnet run --launch-profile DemoSite-Claude
4. Wait 15-20 seconds for startup
5. Query site address endpoint via named pipe to get port and pipe name (see "Query site address via named pipe" section)
6. Report:
   • Task ID for later stopping (save this for future commands)
   • Port number (from site address endpoint)
   • Pipe name (format: umbraco.demosite.{branch-or-worktree})
   • Site URL

For "stop"

1. Find background tasks related to demo site:

   • Look for tasks with "DemoSite" or "demo-site" in name
   • Extract task ID from task list

2. If task found:

   • Use TaskStop with the task ID to stop gracefully
   • Wait 2-3 seconds for cleanup

3. If no task found:

   • Report that no running demo site was found
   • Suggest checking with /demo-site-management status

4. Verify shutdown:

   • Try connecting to the last known port (should fail)
   • Check if background task is gone

5. Report results:

   • Success: "Demo site stopped (task ID: {id})"
   • Failure: "Could not find running demo site"
   • Note: Pipes are automatically cleaned up when process exits

For "generate-client"

1. Check if site is running:
   • Try querying site address endpoint via named pipe (see "Query site address via named pipe" section)
   • Check if any background bash tasks are related to DemoSite
2. If not running, report error with suggestion: "Demo site not running. Start it with /demo-site-management start"
3. Run: npm run generate-client (runs all three packages concurrently)
4. Monitor output for:
   • "Using named pipe: umbraco.demosite.{identifier}" (should appear 3 times)
   • "✓ TypeScript client generated successfully" (should appear 3 times)
   • No errors (EPIPE, connection refused, etc.)
5. Report summary:
   • Success/failure for each package (core, prompt, agent)
   • Pipe name used
   • Whether concurrent connections worked (no errors)

For "status"

Use multi-method detection to determine site status:

1. Query site address endpoint: Try querying via named pipe (see "Query site address via named pipe" section)

   • If successful, site is running and you have port info
   • If fails, continue to other methods

2. Check background tasks: Look for tasks with "DemoSite" or "demo-site" in name/output

   • If found, extract task ID

3. Determine git context:

   • Run git rev-parse --git-dir to check if worktree
   • If worktree, extract name from .git/worktrees/{name}
   • Otherwise use git branch --show-current
   • If no git, identifier is "default"

4. Report comprehensive status:

   • Running: yes/no (based on site address endpoint response)
   • Task ID: if background task found
   • Port: from site address endpoint
   • Pipe name: umbraco.demosite.{identifier}
   • Git context: branch name, worktree name, or "not in git repo"
   • Suggestion: How to start if not running, or how to connect if running

For "restart"

Execute stop operation, wait 3 seconds, then execute start operation.

For "open"

1. Check if demo site is running and get port info:
   • Query site address endpoint via named pipe (see "Query site address via named pipe" section)
   • If fails, report error: "Demo site not running. Start it with /demo-site-management start"
2. Launch default browser with discovered URL:
   • Windows: powershell.exe -Command "Start-Process 'https://127.0.0.1:<port>'"
   • Linux: xdg-open https://127.0.0.1:<port>
   • macOS: open https://127.0.0.1:<port>
3. Report:
   • Browser launched
   • URL opened
   • Note about certificate warning (self-signed HTTPS)
   • Credentials reminder: admin@example.com / password1234

Query Site Address via Named Pipe

The demo site exposes a /site-address endpoint that returns port and pipe information as JSON. Query it via HTTP over named pipes without needing to know the port:

Using Node.js (recommended, cross-platform):

import http from "http";
import { execSync } from "child_process";

// Get pipe name from git context
function getIdentifier() {
    try {
        const gitDir = execSync("git rev-parse --git-dir", { encoding: "utf-8" }).trim();
        if (gitDir.includes("worktrees")) {
            return gitDir.split(/[\\\/]/).find((p, i, arr) => arr[i - 1] === "worktrees") || "default";
        }
        return execSync("git branch --show-current", { encoding: "utf-8" }).trim() || "default";
    } catch {
        return "default";
    }
}

const identifier = getIdentifier().replace(/[^a-zA-Z0-9\-_.]/g, "") || "default";
const pipeName = `umbraco.demosite.${identifier}`;
const socketPath = process.platform === "win32" ? `\\\\.\\pipe\\${pipeName}` : `/tmp/${pipeName}`;

const address = await new Promise((resolve, reject) => {
    http.get({ socketPath, path: "/site-address" }, (res) => {
        let body = "";
        res.on("data", (chunk) => (body += chunk));
        res.on("end", () => (res.statusCode === 200 ? resolve(body) : reject(new Error(`HTTP ${res.statusCode}`))));
    }).on("error", reject);
});

// address = "https://127.0.0.1:44355"

Using curl (PowerShell on Windows):

$identifier = (git branch --show-current).Trim() -replace '[^a-zA-Z0-9\-_]', ''
$pipeName = "umbraco.demosite.$identifier"
curl.exe --unix-socket "//./pipe/$pipeName" http://localhost/site-address

Response format: Plain text HTTPS address

https://127.0.0.1:44355

Detection Helper Commands

Use these commands for reliable cross-platform detection:

Check for background tasks:

# Look for tasks with DemoSite in output (path varies by platform)
# Use /tasks command or check TaskOutput for running demo site tasks

Determine git identifier:

# Get worktree or branch name
git_dir=$(git rev-parse --git-dir 2>/dev/null)
if [[ "$git_dir" == *"worktrees"* ]]; then
  echo "worktree: $(basename $(dirname $git_dir))"
else
  echo "branch: $(git branch --show-current 2>/dev/null || echo 'not-in-git')"
fi

Port Discovery Details

The demo site uses HTTP over named pipes for automatic port discovery:

• Pipe naming: umbraco.demosite.<identifier>
• Identifier logic:
  • Worktree: extracted from .git/worktrees/<name>
  • Main repo: current branch name
  • No git: default
• Site address endpoint: /site-address (returns HTTPS address as plain text)
• HTTP transport: Kestrel listens on both named pipe and HTTP/HTTPS
• Concurrent support: Multiple clients can connect simultaneously
• Implementation: demos/v{major}/Umbraco.AI.DemoSite/Composers/NamedPipeListenerComposer.cs

Common Issues

Pipe not found

• Demo site not running or still starting up
• Solution: Wait 15-20 seconds after start, or check status with /demo-site-management status

Connection refused

• Pipe doesn't exist or connection failed
• Check that site is running: /demo-site-management status
• Verify pipe name matches git context (branch/worktree)

Multiple instances conflict

• Each worktree/branch gets unique pipe name
• Main branch: umbraco.demosite.<branch-name>
• Worktree: umbraco.demosite.<worktree-name>
• No git: umbraco.demosite.default

Success Criteria

After start: Report task ID, pipe name, port, and URL After stop: Confirm process stopped successfully After generate-client: Show success for all three packages (core, prompt, agent) After status: Show running state, port, and pipe connection details
