analytics.page() // NoOp
analytics.track(...) // NoOp
analytics.identify(...) // NoOp

/**
 * Later in your app after getting user permission to load analytics tools...
 */

/* User opted in, enable analytics plugins */

### Using @analytics/mixpanel in HTML via ES Modules

Source: https://getanalytics.io/plugins/mixpanel

<!DOCTYPE html>
<html>
  <head>
    <title>Using @analytics/mixpanel in HTML via ESModules</title>
    <script>
      // Polyfill process.
      // **Note**: Because `import`s are hoisted, we need a separate, prior <script> block.
      window.process = window.process || { env: { NODE_ENV: 'production' } }
    </script>
    <script type="module">
      import analytics from 'https://unpkg.com/analytics/lib/analytics.browser.es.js?module'
      import analyticsMixpanel from 'https://unpkg.com/@analytics/mixpanel/lib/analytics-plugin-mixpanel.browser.es.js?module'
