chore(rrweb): move the recorder onto upstream rrweb 2.2.1 - #190
Moves @bugsee/rrweb onto upstream rrweb 2.2.1 (published 2026-11-06, latest on npm): rrweb / @rrweb/types to ^2.2.1, and the Bugsee-hardened record-only bundle rebuilt from bugsee-port-2.2.0-iframe-block + tag rrweb@2.2.1.
Fork rebuild (bugsee/rrweb) — prepared, not pushed
This agent’s GitHub App is installed only on bugsee/bugsee-javascript, so it cannot push or open a PR on bugsee/rrweb. The rebuild was done locally and the dist files are vendored here so the SDK can actually run 2.2.1.
A collaborator with write access to bugsee/rrweb can push the already-built branches from a checkout of that repo:
Recreate bugsee-port-2.2.1 from bugsee-port-2.2.0-iframe-block, merge tag rrweb@2.2.1.
Resolve the one conflict in packages/rrweb-snapshot/src/snapshot.ts by keeping P4 (!isBlockedNode). Upstream #1964’s _isBlockedElement(n, blockClass, blockSelector) is a weaker subset (no unblockSelector, no ancestor re-check).
Replace instanceof HTMLMediaElement in initMediaInteractionObserver with the player’s AUDIO/VIDEOnodeName check. Upstream #1673’s instanceof is always false for media inside an iframe (other realm) and dropped iframe media recording.
Rebuild dist like 2.2.0: vite build --config vite.config.entries.js then esbuild dist/rrweb-record.js --bundle --minify --format=esm. Two clean rebuilds were byte-identical.
Commit on bugsee-dist-2.2.1 (from bugsee-dist-2.2.0-iframe-block): version 2.2.1, peerDeps ^2.2.1.

bugsee-port, bugsee-dist, and main on the fork were not modified.
What changed upstream (2.2.0 → 2.2.1)
Media-element events (#1673): do not record play/pause/seek on non-media; player try/catches old recordings. Bundle uses a cross-realm nodeName check so iframe <video>/<audio> still record.
postcss 8.5.32 (#1998):CVE-2026-41305, inlined in rrweb-snapshot (hence the bundle size bump).
CSS url() (#1993, #1956): leave fragment-only (url(#filter)) and blob: urls unchanged when absolutifying.
Blocked iframe documents (#1964): do not serialize a blocked iframe’s document. Subsumed by P4 (already in the 2.2.0-iframe-block pin).
Iframe navigation (#1977): tests only; the source fix shipped in 2.2.0.
@rrweb/types@2.2.1 is a version bump; public type surface unchanged. No breaking changes.

Review of #190: move the recorder onto upstream rrweb 2.2.1
I read the full diff and the surrounding code. I did not run tests or builds, so the test results in the PR description are unverified by me. I could not read the minified vendor/rrweb-record/record.js line by line. I only grepped it. The bundle does contain the cross-realm check, ["AUDIO","VIDEO"].includes(C.nodeName), followed by re(C,i,o,!0), and no HTMLMediaElement reference. That matches the description.
Findings (posted inline)

Summary
P2
packages/rrweb/package.json:35
The content-hashed git pin becomes an unverifiable vendored 198 KB minified blob. The cited fork SHAs are not on GitHub, so the "rebuilt from bugsee-port-2.2.1" claim can't be checked. The blob is inlined into the published SDK and runs in customer pages.
P2
packages/rrweb/src/index.test.ts:20
The new test only asserts the hand-written package.json version string. Nothing tests the iframe-media (nodeName) behaviour, which is the one deliberate deviation from upstream. A plain upstream record.js would pass every test I looked at.
Minor notes (no inline comment)
The lockfile diff has unrelated churn: webpack, vite and html-webpack-plugin peer-resolution suffixes changed (postcss@8.5.32, jiti, yaml). It is probably a harmless re-resolution from the install, but it makes the diff harder to audit.
tsup.config.ts:8-11 and the comment in index.ts still say "~56 KB gzip". index.ts was updated to ~61 KB. The tsup comment was not.
I checked minimumReleaseAge. pnpm-workspace.yaml only excludes @bugsee/bugsee-cli@0.7.11, which matches the PR's claim that no exclude was needed.
Overall risk: Low to Medium. The version bump and lockfile changes are mechanical and consistent. The risk is provenance and test coverage, not logic.
Merge recommendation: Approve once the fork branches are pushed and the dependency goes back to the git pin. Until then it is acceptable to merge only if a tracking issue exists and the bundle is pinned by sha256. I would not cut a release from the vendored copy.
Most important issues to fix:
Push bugsee-dist-2.2.1 to bugsee/rrweb and restore the github: pin, or add a sha256 check for record.js.
Add a regression test for iframe <video>/<audio> media-interaction recording against the vendored bundle.
Positives:
The PR description is unusually transparent about what was and wasn't done.
The P4-over-upstream-#1964 conflict resolution is reasoned and documented.
The cross-realm instanceof pitfall was caught and fixed.
Rebuilds were checked to be byte-identical.
The size growth is documented against the budget.
vendor/ was excluded from biome, and PROGRESS.md was updated.

Bug Fixes
Updated the recording components to rrweb 2.2.1, retaining existing iframe handling and capturing media interactions in videos inside iframes when cross-origin iframe recording is disabled.
Added automated checks for the recording package version and bundled recording file.
The PR adds a vendored @bugsee/rrweb-record 2.2.1 package and points the wrapper’s development dependency to it. It updates rrweb and @rrweb/types to ^2.2.1. Tests verify the package version and bundle hash, and check that recording emits a media-interaction event for iframe video playback with cross-origin iframe recording disabled. The PR also updates progress and bundle-size comments, excludes vendor from Biome’s matched files, and adds the vendored directory to Turbo’s global dependencies.

Severity: P2 Medium Problem: This test only reads the version string from the hand-written vendor/rrweb-record/package.json. It does not check the contents of record.js. Impact: The one behavioural change the PR makes to the bundle (the cross-realm AUDIO/VIDEOnodeName check in place of upstream's instanceof HTMLMediaElement) has no regression test in this repo. If the vendored record.js is later swapped for the upstream build, or rebuilt from the wrong branch, this test still passes. instanceof is always false for media inside an iframe, so iframe <video>/<audio> recording would silently stop. Scenario: Someone replaces record.js with a plain upstream 2.2.1 build and leaves package.json alone. @bugsee/rrweb tests, @bugsee/replay tests and the e2e suites that I could see all stay green. (I did not run them.) Fix: Add a jsdom or Playwright test that records a <video> inside a same-origin iframe, triggers play, and asserts a media-interaction event (source 7) is emitted. Optionally pin a sha256 of record.js in the test, to catch an accidental swap and to tie the vendored file to the SHA documented in the README.

Severity: P2 Medium Problem: The dependency changes from a content-addressed git pin (github:bugsee/rrweb#<sha>, which carried an integrity hash in the lockfile) to a 198 KB minified blob committed directly into this repo. The lockfile now records only resolution: {directory: vendor/rrweb-record}. The SHAs the README and PROGRESS cite (69633fc…, 5a46e7d…) are not on GitHub, so nobody can rebuild the file and compare it today. Impact: This bundle is inlined into the published @bugsee/rrweb and runs inside customers' pages on every recorded DOM mutation. Review can't verify minified code, and the provenance claim ("same files as bugsee-dist-2.2.1") rests on this PR's description alone. This is a supply-chain and auditability regression compared with the previous pin. Scenario: The fork branches are never pushed, or are force-pushed. The vendored file then becomes the only copy, and no one can check what it contains against source. Fix: Don't release from this branch until bugsee-dist-2.2.1 is pushed and this goes back to the git pin. If it has to merge first, add a TODO or tracking issue for the switch-back and a CI or test check of the record.js sha256, so the file can be tied to the commit once it exists.

Test media behavior through the wrapper.
The wiring test accepts an older callable recorder beside the 2.2.1 manifest. Add a browser test that checks iframe video interactions are recorded and non-media play events are ignored. This covers both cross-realm handling and the new media guard.

Review: rrweb 2.2.1 vendored recorder
The recorder itself looks like the claimed rebuild. I checked the minified vendor/rrweb-record/record.js (198322 B / 62407 B gzip) rather than taking the PR body as proof:
Fork privacy surface is present (maskAllText, maskAttributeFn, unblockSelector, unmaskInputSelector, …).
P4 iframe-block is present, not the weaker upstream #1964 check: $r walks ancestors and shadow hosts, fail-closes on throw, attachIframe returns false when blocked, load listener is skipped when needBlock, emit-time isDocBlocked is wired into shadow / stylesheet / adopted-sheet managers.
Media interaction uses ["AUDIO","VIDEO"].includes(nodeName) (no instanceof HTMLMediaElement).
@rrweb/types@2.2.1IncrementalSource is still 0–16, so iframe-guard.ts source numbers are still valid.
pnpm install --frozen-lockfile succeeds. @bugsee/rrweb tests 2/2. @bugsee/replaymasking.integration.test.ts48/48 against this bundle. I did not run Playwright replay e2e (no browsers in this environment).
Overall risk: Low Merge recommendation: request changes — one P2 to fix before the next vendor-only rebuild (including pnpm release, which is turbo run build). The 2.2.1 recorder contents are not the blocker.
Most important to fix
Hash vendor/rrweb-record/** in turbo inputs (see inline comment). Without that, a record.js-only edit is invisible to @bugsee/rrweb#build and to every downstream ^build test cache.
Positive
Vendoring is the right answer to the private-git EXOTIC_SUBDEP problem, the 2.2.1 patches landed, P4 was kept over #1964, and the media nodeName guard is the correct cross-realm fix. Size stays under the ~90 KB add-on budget.
Residual (not blocking)
Claimed fork SHAs (69633fc1 / 5a46e7db) are not on GitHub, so this cannot be independently rebuilt; verification here is behavioral + string inspection of the blob.
Vendored index.d.ts still only adds maskAttributeFn (known wrapper/record type mismatch).
The new wrapper test only asserts package.json version 2.2.1, not bundle bytes.
sha256 pin + iframe-media regression test (claude P2): index.test.ts pins record.js and records a <video> in an iframe, asserting a MediaInteraction event. I mutated the bundle's nodeName check and both tests failed.
Turbo staleness (cursor P2): vendor/rrweb-record/** is now in globalDependencies. A dry run confirms record.js is hashed.
Provenance / git-pin switch-back (claude P2): needs someone with write access to push bugsee-dist-2.2.1 to bugsee/rrweb. The sha256 pin ties the blob until then.
Skipped (low value): moving rrweb/@rrweb/types from peer to regular deps in the vendor package, and inlining the recorder declaration in published types. The vendor package is private and inlined by tsup, and @bugsee/rrweb already depends on both type packages.
I read the new commit's diff and the surrounding code. I did not install dependencies or run tests, builds or Playwright, so the test results in the PR description are still unverified by me. I did check the vendored bundle directly: sha256sum vendor/rrweb-record/record.js is b87d6029…3135, which matches the pin in the test. The bundle contains ["AUDIO","VIDEO"].includes(C.nodeName) and no HTMLMediaElement reference.
Earlier findings: fixed
Earlier finding
Status
The vendored record.js was unverifiable (my P2, Cursor)
Mitigated.index.test.ts:26-30 pins its sha256, and the README says to update the pin on rebuild (README.md:12). The fork SHAs are still not on GitHub, so this ties the file to a hash but not to a source commit.
There was no regression test for iframe <video>/<audio> (my P2, CodeRabbit)
Fixed.index.test.ts:32-48 records a <video> in a same-origin iframe and asserts a source-7 incremental event. I could not confirm that it fails against a plain upstream build.
Turbo did not hash the vendored recorder (Cursor P2)
Fixed.turbo.json:3 now lists vendor/rrweb-record/** in globalDependencies.
README esbuild recipe wrote to stdout (CodeRabbit)
Fixed. It now passes --outfile=<repo>/vendor/rrweb-record/record.js.
index.d.ts was missing the fork options (CodeRabbit, Cursor)
Fixed.maskAllText, unmaskTextClass, unmaskTextSelector, unblockSelector and unmaskInputSelector were added (index.d.ts:9-16).
PROGRESS.md gzip figure for 987d0765 (CodeRabbit)
Fixed. It now says 59,348. The PR description still says 59,269, and the description is the only place left with the old number.
Stale "~56 KB" comment in tsup.config.ts (my minor note)
Fixed. It now says ~62 KB.
Items I looked at and did not flag
CodeRabbit: inline @bugsee/rrweb-record types in the published .d.ts, and make rrweb and @rrweb/types regular dependencies of the vendored package. Neither was introduced by this PR. The old git pin had the same export { record } from '@bugsee/rrweb-record' declaration shape. The vendored package is a private devDependency inlined by tsup, so its peer-dependency metadata never reaches consumers. It would be worth confirming in a follow-up that the built dist/index.d.ts resolves for a consumer, but I am not blocking on it.
Heavier turbo invalidation. A change to record.js now invalidates every task's cache, because the path is in globalDependencies. That is the safe direction for a rarely changed file. @bugsee/rrweb's inputs would be a narrower alternative, but I don't think it is worth a change.
New findings
None. I found no new issues in the latest commit.
Summary
Overall risk: Low.
Merge recommendation: Approve. This is acceptable to merge as an interim step. The sha256 pin, the regression test and the turbo hashing cover what I and the other reviewers raised. Please open a tracking issue for switching back to github:bugsee/rrweb#5a46e7db… once bugsee-dist-2.2.1 is pushed to the fork. I would not cut a release from the vendored copy until the fork branches are pushed and the source is independently checkable.
Most important remaining items:
Push bugsee-port-2.2.1 and bugsee-dist-2.2.1 to bugsee/rrweb, then restore the git pin. This is the only way to get a source-level provenance check.
Optionally, correct the 59,269 B figure in the PR description to 59,348 B.
Positives:
The review feedback was addressed quickly and completely.
The sha256 pin uses the same hash as the vendored file.
The regression test targets the one deliberate deviation from upstream.
Keeping P4 over upstream #1964 and the cross-realm nodeName fix are both documented.

Update the media-event assertion in the test so it compares the event’s ID with
the video ID from the iframe attach mutation, rather than only checking that a
media event exists. Preserve the existing event type and source checks.

Second round (CodeRabbit, both minor): README rebuild recipe now names the bugsee/rrweb checkout, the working directory (packages/rrweb/) and the SDK root for --outfile. Not changing turbo.json: the global hash is deliberate, because the file changes rarely and cross-package invalidation is the safe direction. Claude's re-review reached the same conclusion.

Review: rrweb 2.2.1 vendored recorder (re-review of 30d9d7f)
Prior P2 is fixed. turbo.json now lists vendor/rrweb-record/** in globalDependencies. I confirmed a record.js-only byte change flips @bugsee/rrweb#build's hash (fe4165af → f4692882) and restoring the file restores the original hash. pnpm release (turbo run build) will rebuild when the vendor blob changes.
Findings
No remaining P0–P3 issues in this PR.
The follow-up commits also close the other review gaps that were in the same area:
sha256 pin in packages/rrweb/src/index.test.ts matches the file (b87d6029…3135).
The new iframe <video> test is a real cross-realm check: in this jsdom, video instanceof window.HTMLMediaElement is false and nodeName is VIDEO. I ran the wrapper suite 4/4 and the media test 10 times sequentially with no flake.
Vendored index.d.ts now declares the fork options (maskAllText, unblockSelector, …), so the wrapper's record and recordOptions agree.
I also re-checked the blob and the callers, not just the new commits:
@rrweb/types@2.2.1IncrementalSource is still 0–16, so iframe-guard.ts source numbers stay valid.
tsup inlines the recorder (dist/index.js 268595 B); it is not a runtime re-export of the file: package.
@bugsee/replaymasking.integration.test.ts48/48 against this bundle.
Overall risk: Low
Merge recommendation: approve as an interim vendor until bugsee-dist-2.2.1 is on bugsee/rrweb and the git pin is restored.
Most important remaining items
Push bugsee-port-2.2.1 / bugsee-dist-2.2.1 and switch @bugsee/rrweb-record back to github:bugsee/rrweb#5a46e7db3c97c1e87ded58e1b83c6f5ef43fec34. The sha256 pin ties the blob; it does not make the claimed source SHAs checkable.
Current GitHub CI on this head is red for reasons outside this diff: @bugsee/nodelaunch.test.ts native-crash recovery (puts.length stayed 0) and e2e bugsee-cli postinstall HTTP 504. I did not treat those as blockers for this change.
I did not run Playwright replay e2e (no browsers here).
Positive
The review follow-ups are the right ones (turbo hash, content pin, iframe-media regression). P4 was kept over #1964, and the nodeName media guard is the correct cross-realm fix. Size stays under the ~90 KB add-on budget.
The new commit changes one line in vendor/rrweb-record/README.md. It rewrites the rebuild recipe to say the commands run from packages/rrweb/ of a bugsee/rrweb checkout and to define <sdk-checkout> as this repo's root. Nothing executable changed since 0afa238f.
I did not install dependencies or run tests, builds or Playwright. The test results in the PR description are still unverified by me. I did check two things directly:
sha256sum vendor/rrweb-record/record.js gives b87d6029…3135, which matches the pin in packages/rrweb/src/index.test.ts:29.
The bundle still contains ["AUDIO","VIDEO"].includes(C.nodeName) and has no HTMLMediaElement reference.
Earlier findings
All are still addressed:
Unverifiable vendored blob: mitigated by the sha256 pin.
No iframe-media regression test: fixed by index.test.ts:32-48.
Turbo hashing:vendor/rrweb-record/** is in globalDependencies. The author's reasons for keeping it global are sound.
README recipe:--outfile is fixed, and the checkout and working directory are now named.
index.d.ts fork options and the stale tsup size comment: fixed.
New findings
None.
Optional, not blocking
index.test.ts:47 only checks that some source-7 event exists. It does not check that the event's id matches the iframe <video>'s node id. CodeRabbit raised this as a nitpick. The nodeName check is the behaviour under test, so the current assertion is enough for the regression.
The PR description still lists the 987d0765 gzip size as 59,269 B. PROGRESS.md already says 59,348 B.
Summary
Overall risk: Low.
Merge recommendation: Approve as an interim step. I would not cut a release from the vendored copy until bugsee-port-2.2.1 and bugsee-dist-2.2.1 are pushed to bugsee/rrweb and the github: pin is restored. Please open a tracking issue for that switch-back.
Most important remaining item: push the fork branches and restore the git pin. That is the only way to check provenance against source.
Positives:
The sha256 pin, the regression test and the README provenance notes all point at the same bundle.
The follow-up commits were small and targeted.
Keeping P4 over upstream #1964, and the cross-realm nodeName fix, are documented.
