+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+rrweb is a web session recording and replay library. It records user interactions on web pages (DOM mutations, mouse movements, input events, etc.) and can replay them faithfully. The project is a TypeScript monorepo managed by Yarn workspaces and Turborepo.
+
+## Common Commands
+
+```bash
+# Install dependencies (use yarn, NOT npm)
+yarn install
+
+# Build all packages
+yarn build:all
+
+# Watch mode for all packages (auto-rebuild on changes)
+yarn dev
+
+# Run all tests across the monorepo
+yarn test
+
+# Run tests for a specific package (run from package directory)
+cd packages/rrweb && yarn test          # builds then runs tests
+cd packages/rrweb && yarn retest        # runs tests without rebuild (faster)
+cd packages/rrweb-snapshot && yarn test
+
+# Watch mode tests for a specific package
+cd packages/rrweb && yarn test:watch
+
+# Update test snapshots
+cd packages/rrweb && yarn test:update   # or retest:update for no rebuild
+
+# Lint
+yarn lint
+
+# Format
+yarn format
+
+# Type check all packages
+yarn check-types
+
+# REPL tool (interactive testing in browser)
+yarn repl
+```
+
+## Architecture
+
+### Package Dependency Graph
+
+The core data flow is: **snapshot** captures DOM → **record** observes mutations → **replay** reconstructs events.
+
+```
+@rrweb/types          (shared type definitions, no deps)
+@rrweb/utils          (shared utilities)
+rrweb-snapshot        (DOM serialization/deserialization, depends on types/utils)
+rrdom / rrdom-nodejs  (virtual DOM for Node.js environments)
+rrweb                 (main package: record + replay, depends on all above)
+  ├── src/record/     (DOM mutation observers, event capture, canvas recording)
+  └── src/replay/     (event replay engine, timer, canvas replay, style injection)
+rrweb-player          (Svelte-based player UI)
+@rrweb/all            (convenience package combining record + replay)
+@rrweb/packer         (pack/unpack utilities for rrweb event data)
+```
+
+### Plugin System
+
+Plugins live in `packages/plugins/` and follow a record/replay pair pattern:
+- `rrweb-plugin-console-record` / `rrweb-plugin-console-replay` — console logging
+- `rrweb-plugin-canvas-webrtc-record` / `rrweb-plugin-canvas-webrtc-replay` — canvas via WebRTC
+- `rrweb-plugin-sequential-id-record` / `rrweb-plugin-sequential-id-replay` — sequential IDs
+
+### Build System
+
+- **Turbo** orchestrates builds via `turbo.json` with task dependency graph
+- Each package uses **Vite** in library mode (`vite.config.default.ts` shared config)
+- Output formats: ES modules (`.js`), CommonJS (`.cjs`), UMD (`.umd.cjs`), plus TypeScript declarations (`.d.ts` / `.d.cts`)
+- `DISABLE_WORKER_INLINING=true` env var disables worker inlining for Chrome extension builds
+- Test runner is **Vitest** (some older packages still use Jest)
+- Tests in `packages/rrweb` use **Puppeteer** for browser-based integration tests; set `PUPPETEER_HEADLESS=true` for headless mode
+
+### Key Source Paths
+
+- `packages/rrweb/src/record/` — recording logic (mutation observer, iframe/shadow-dom managers, canvas observers)
+- `packages/rrweb/src/replay/` — replay engine (timer, state machine via @xstate/fsm, canvas replay, style injection)
+- `packages/rrweb/src/entries/record.ts` / `replay.ts` — separate entry points for record-only or replay-only bundles
+- `packages/rrweb-snapshot/src/snapshot.ts` — DOM → serializable data structure
+- `packages/rrweb-snapshot/src/rebuild.ts` — serialized data → DOM reconstruction
+- `packages/types/src/` — shared event types (`eventWithTime`, `EventType`, `IncrementalSource`)
+
+### ESLint Configuration
+
+- Uses `@typescript-eslint` with type-checked rules
+- `camelCase` rule allows `rr_`, `legacy_`, `UNSAFE_`, `__rrweb_` prefixed identifiers
+- TSDoc syntax is enforced via `eslint-plugin-tsdoc`
+- Browser compatibility checked via `eslint-plugin-compat`
