Project Structure

rrweb mainly includes two funtions:

Record: The record function is used to record all the mutations in the DOM
Replay: The replay function is to replay the recorded mutations one by one according to the corresponding timestamp.

Roadmap

storage engine: do deduplication on a large number of rrweb sessions
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.
