Migrate Google Analytics from UA to GA4 Measurement Protocol

[Copilot]

Universal Analytics is deprecated as of July 1, 2023. This PR migrates to GA4 Measurement Protocol v2 to maintain analytics functionality.

Changes

GoogleAnalytics.ts

• Endpoint: /collect → /mp/collect
• Protocol: Query string → JSON payload with client_id and events[]
• Credentials: UA tracking ID → GA4 measurement ID + API secret (env var support)
• Event mapping: screenview → screen_view, event → cli_event, exception → exception
• Custom dimensions (cd1-cd14) mapped to GA4 event parameters

GoogleAnalyticsParameters.ts

• Marked UA-specific fields (tid, an, ua, uid, v) as @deprecated
• Retained for backward compatibility

GoogleAnalytic-spec.ts

• Updated assertions for GA4 endpoint and JSON content-type
• Fixed directory creation with recursive: true

Configuration

Set via environment variables (recommended):

IGNITEUI_CLI_GA4_MEASUREMENT_ID="G-XXXXXXXXXX"
IGNITEUI_CLI_GA4_API_SECRET="your-api-secret"

Or update defaults in GoogleAnalytics.ts (lines 29-30).

Example

Existing code works unchanged:

GoogleAnalytics.post({
  t: "screenview",
  cd: "Start",
  cd1: "angular",
  cd2: "igx-ts"
});

GA4 payload generated:

{
  "client_id": "hashed-user-id",
  "events": [{
    "name": "screen_view",
    "params": {
      "screen_name": "Start",
      "framework": "angular",
      "project_type": "igx-ts",
      "engagement_time_msec": "100"
    }
  }]
}

[!WARNING]

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.google-analytics.com
  • Triggering command: Ignite UI CLI (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
