Async Loading & Command Queue Demo

How this works: This page demonstrates the command queue pattern used by production analytics tools. Commands are pushed to window._cq (an array) before the collector script loads. When the script loads (simulated with a delay), it drains the queue and replaces it with a live proxy. Any commands pushed after the script loads execute immediately.

Recommended Embed Pattern

<!-- Analytics Collector -- Place in <head> --> <script> window._cq = window._cq || []; _cq.push(['init', { endpoint: 'https://analytics.example.com/collect', enableVitals: true, enableErrors: true, sampleRate: 1.0 }]); </script> <script async src="https://analytics.example.com/collector-v9.min.js"></script>
