* Fix sheet insertion Restore skip duration Use virtualStyleRulesMap to re-populate stylesheet on Flush event Clear virtualStyleRulesMap after flush applied * Support rule deletion in virtual processing * Simply restoreNodeSheet with early aborts * Encountered a bug where firstFullSnapshot was played twice because timer was immediately started and reached the snapshot before the setTimeout returned * Ignoring a FullSnapshot needs to be a one-time only thing, as otherwise we'll ignore it after scrubbing (restarting play head at a particular time). This is a problem if mutations have altered the player state, and we try to replay those mutations, so we e.g. try to remove an element that has already been removed because we haven't reset the FullSnapshot state * Some `npm run typings` related fixups * add basic html snapshot functionality * move restoreNodeSheet to it's own module * Refactor virtual style rules to buffer changes. Only applies changes on flush. `virtualStyleRulesMap` now works with strings instead of CSSRules. CSSRules can only be via made `.insertRule` on CSSStyleSheet in most browsers. And `new CSSStyleSheet()` only works in Chrome currently. * remove unused code * move VirtualStyleRules from CSSRule to string in tests * correct paths for tests * naming * create and restore style snapshots for virtual nodes * update replayer snapshot * move storeCSSRules to virtual-styles.ts * try/catch access to .sheet in case of access errors * clean up tests Co-authored-by: Vladimir Milenko <vladimir.milenko@uber.com> Co-authored-by: Eoghan Murray <eoghan@getthere.ie>
rrweb
The new adventure of the rrweb community
I have joined Github Sponsors and highly appreciate your sponsorship.
rrweb refers to 'record and replay the web', which is a tool for recording and replaying users' interactions on the web.
Guide
📚 Read the rrweb guide here. 📚
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.
- Fork the rrweb component repository you want to patch.
- Run
npm installto install required dependencies. - Patch the code and pass all the tests.
- Push the code and create a pull request.
In addition to adding integration tests and unit tests, rrweb also provides a REPL testing tool.
