rrweb refers to 'record and replay the web', which is a tool for recording and replaying users' interactions on the web.

Publishing @chromaui/rrweb-snapshot

Chromatic maintains this fork of rrweb-io/rrweb solely to publish a version of rrweb-snapshot that supports constructable stylesheets for Chromatic e2e capture purposes.

To distinguish Chromatic-specific builds from those coming from rrweb-io, a -noAbsolute label is appended to the end of the package version. If more than one Chromatic build is produced based off of the same rrweb-io version, a number is appended to the end of that label (e.g. 2.0.0-alpha.17-noAbsolute.1).

1. In packages/rrweb-snapshot/package.json, set the appropriate -noAbsolute.X version
2. CD to packages/rrweb-snapshot
3. Run npm publish

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

• 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

• serialization
• incremental snapshot
• replay
• sandbox

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.

Typescript handbook

1. Fork this repository.
2. Run yarn install in the root to install required dependencies for all sub-packages (note: npm install is not recommended).
3. Run yarn build:all to build all packages and get a stable base, then yarn dev in the root to get auto-building for all the sub-packages whenever you modify anything.
4. Navigate to one of the sub-packages (in the packages folder) where you'd like to make a change.
5. Patch the code and run yarn test to run the tests, make sure they pass before you commit anything. Add test cases in order to avoid future regression.
6. If tests are failing, but the change in output is desirable, run yarn test:update and carefully commit the changes in test output.
7. Push the code and create a pull request.

Protip: You can run yarn test in the root folder to run all the tests.

In addition to adding integration tests and unit tests, rrweb also provides a REPL testing tool.
