Project Structure

rrweb is mainly composed of 3 parts:

rrweb-snapshot, including both snapshot and rebuilding features. The snapshot is used to convert the DOM and its state into a serializable data structure with a unique identifier; the rebuilding feature is to rebuild the snapshot into corresponding DOM.
rrweb, including two functions, record and replay. The record function is used to record all the mutations in the DOM; the replay is to replay the recorded mutations one by one according to the corresponding timestamp.
rrweb-player, is a player UI for rrweb, providing GUI-based functions like pause, fast-forward, drag and drop to play at any time.

Roadmap

rrdom: an ad-hoc DOM for rrweb session data #419
storage engine: do deduplication on a large number of rrweb sessions
more end-to-end tests
compact mutation data in common patterns
provide plugins via the new plugin API, including:
- XHR plugin
- fetch plugin
- GraphQL plugin
- ...

Internal Design

Contribute Guide

Since we want the record and replay sides to share a strongly typed data structure, rrweb is developed with typescript which provides stronger type support.
