@cubenest/rrweb-core

The shared rrweb capture + masking engine behind tracelane and peek — vendored PostHog fork, PII masking, network/console capture, large-DOM throttling. Not a standalone product.

Shared rrweb-based capture substrate. Used by tracelane and peek.

Not intended for direct consumption — depend on a product package instead. It exists to share the masking and capture primitives (PII masking selectors + regex bank, body/header redaction, network/console capture, large-DOM throttling) between the two product families so the privacy and recording behaviour stay identical.

What's in here

• Vendored PostHog rrweb fork (@posthog/[email protected])
• PII masking primitives (selectors + regex bank + body/header redaction)
• Large-DOM throttling defaults (mutation guard, data-URL guard, single-event size cap)
• Shadow DOM adapter
• Screenshot fallback interface
• Network capture abstraction (CDP and chrome.webRequest implementations)
• Console capture
• Compression helpers (fflate)
• IndexedDB persistence helper
• Compatibility matrix

Versioning

Independent semver. Breaking changes are coordinated across tracelane and peek releases.
