We’ve introduced a new URL Tracking plugin for the Amplitude Session Replay Browser SDK!

This enhancement ensures we accurately capture client-side navigations in SPAs (Single Page Applications), a critical prerequisite for features like Jump to Key Moments.

By default, rrweb only emits Meta events during full page loads or resizes — meaning SPA route changes using pushState, replaceState, or hash routing were previously invisible. With this plugin, we now emit URL change events for those too! :tada:

Key Features include three tracking modes:

• Polling Mode (opt-in): Periodic checks for URL changes
• History API + Hash Routing (default): Listens to pushState, replaceState, popstate, and hashchang
• Hash Routing: Fallback for environments lacking History API

Why it matters: This brings visibility to critical navigation behavior that rrweb misses — enabling more complete replays, unlocking accurate navigation context, and setting us up for richer replay intelligence.
