* Move mutation processing into it's own object. This should stand on it's own as a refactor, but is intended as a basis for exposing the new MutationBuffer object to further outside control e.g. to 'mute' or batch up mutation emission when the page becomes inactive from a https://developer.mozilla.org/en-US/docs/Web/API/Page_Visibility_API point of view * The `processMutations` function needed to be bound to the `mutationBuffer` object, as otherwise `this` referred to the `MutationObserver` object itself * Neglected to add this output of `npm run typings` * Get around the binding problem by using Arrow function expressions * Prettier formatting
rrweb
rrweb refers to 'record and replay the web', which is a tool for recording and replaying users' interactions on the web.
Currently, rrweb has already solved many difficult problems in recording and replaying, but the data structure may still be changed before the release of Version 1.0. So please be cautious to use rrweb in the production environment.

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
- rrweb
- handle cross-domain request errors
- record in web worker
- implement transmission data compression
- verify recording in mobile browser
- rrweb-player
- implement efficient progress bar drag and drop control
- add full screen mode
- extensions
- hijack the console API and record corresponding events
- hijack Ajax/fetch API and record request events
- use TraceKit to log exception events
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.
