I reviewed this PR and didn't find any bugs. Deferring to a human because packages/bun-types/ has a CODEOWNER, and the PR flags an explicit decision point (the Promise.withResolvers() resolve signature now requires a value, affecting ~136 call sites in test/).
What was reviewed:
- Each realigned signature (
resize,grow,setFromBase64,fromAsync,withResolvers,try,getOrInsert,FormDataIterator) checked against the named TypeScript lib file. Mock<T> = T & MockInstance<T>— verifiedspyOnalready returnsMock<...>so it picks up the intersection, and the required-param overload preservesmock()/mock<T>()inference.BunConsumerConvenienceMethodsmove intoBun.__internal— confirmed no other references remain and the@ts-expect-errorguard inglobals.tsstill holds.- The new dependency-scan test's package-name split handles scoped packages and its non-empty guard prevents a vacuous pass.
Extended reasoning...
Overview
This PR touches only TypeScript declaration files in packages/bun-types/ (bun.d.ts, globals.d.ts, overrides.d.ts, test.d.ts), the package's package.json/bun.lock (adding undici-types as a dependency), and the bun-types integration test plus its fixtures. No native code and no runtime behavior is changed. It closes eight open type issues by aligning bun-types' ECMAScript-augmentation signatures with TypeScript's lib files, fixing five declarations that diverged from the runtime, and declaring the undici-types dependency that was previously resolved only via hoisting.
Security risks
None. Pure .d.ts changes plus a types-only npm dependency; nothing here executes at runtime.
Level of scrutiny
Moderate-to-high. The changes are type-only, but bun-types is published to npm and consumed by every Bun user, so signature changes are user-facing API surface. The PR is exceptionally well-documented (per-issue table, fail-before diagnostics, runtime verification of each behavioral claim, an impact probe over test/), and every change ships a fixture that fails without it. The bug-hunting pass found nothing. The residual reasons for a human look are policy/design, not correctness.
Other factors
packages/bun-types/is owned by a CODEOWNER, which by itself takes this out of auto-approval scope.- The author explicitly surfaces a decision: aligning
PromiseWithResolverswith lib.es2024 makesresolve()(no arg) a type error unless<void>is supplied. That is the standard TypeScript behavior and arguably correct, but it is a deliberate tightening a maintainer should sign off on. Mock<T>changes from aninterfaceto a type alias (T & MockInstance<T>). This is the right fix for generic/overloaded call signatures, but it removes the ability to declaration-merge intoJestMock.Mock— worth a maintainer glance.- Adding
undici-types: "*"as a published dependency ofbun-typesis a packaging decision (range choice, potential for two copies under isolated linkers, which the PR notes analyzes) that the package owner should confirm. - The PR supersedes five single-issue PRs; a maintainer will want to close those alongside this one.

I reviewed this PR and didn't find any bugs. Deferring to a human because the description flags a decision point (Promise.withResolvers() now requires resolve to receive a value, breaking ~136 call sites in test/), and it adds undici-types as a published dependency of bun-types — both are user-facing API/packaging calls a maintainer should sign off on.
What was reviewed:
- Each declaration change traced to runtime or a TypeScript lib file (WebView
goBack/goForward, WebSocketErrorEvent,setFromBase64options,resize/growreturningvoid,FormDataIterator). Mock<T>interface →T & MockInstance<T>: the public export was already a type alias, so declaration-merging paths are unchanged.- The new dependency-scan test guards itself against an empty glob result.
Extended reasoning...
Overview
This PR fixes eight open bun-types issues in one pass: five declarations that didn't match runtime behavior (Mock<T>, WebSocket error event, WebView.back(), FormData iteration, ReadableStream.text() under lib.dom), a reorganization of the ECMAScript augmentations in globals.d.ts to match TypeScript's lib files exactly (fixing core-js TS2430 conflicts and adding Map.getOrInsert), and adding undici-types as a declared dependency. It touches 5 .d.ts files in packages/bun-types/, package.json/bun.lock, and 8 test/fixture files. ~720 lines added, ~240 removed.
Security risks
None. This is entirely type declarations and type-check fixtures; no runtime code changes.
Level of scrutiny
Medium-high. While types-only, this is the published @types/bun surface that every Bun user consumes. Several changes are technically breaking for users who wrote code against the previous (incorrect) types: WebView.back() → goBack(), Mock<T> interface → intersection type, setFromBase64(s, offset) → setFromBase64(s, options), and Promise.withResolvers() now requiring a value argument to resolve. Each individual change is well-justified and matches runtime/spec, but the aggregate is a substantial API-surface change.
Other factors
- The PR description explicitly contains a "To decide on:" section about
Promise.withResolvers()— the author is asking for a maintainer decision on whether aligning with TypeScript's lib (which makes bareresolve()an error) is acceptable given it breaks 136 call sites intest/. That decision should not be made by an automated reviewer. - Adding
undici-types: "*"as a published dependency ofbun-typesis a packaging change that affects install trees for every consumer. The PR notes this can install a second copy alongside@types/node's pinned version and argues it type-checks cleanly, but a maintainer should confirm the*range (vs. pinning) is the intended policy. - Test coverage is thorough: each fix has a fixture, the new
core-js-types.tsfixture guards against future lib drift, and the dependency-scan test has a non-vacuous guard. The integration test passes on release and the fail-before evidence is documented. - No prior human reviews or outstanding comments to address.

I reviewed this PR and didn't find any bugs. Because it touches the CODEOWNER-covered packages/bun-types/ public API surface and flags an explicit "to decide on" breaking change (Promise.withResolvers().resolve() now requires an argument), a human look from the types owner would still be worthwhile.
What was reviewed:
- ECMAScript region signatures cross-checked against the named TypeScript lib files (resize/grow return
void,setFromBase64second arg is options not offset,fromAsync/withResolvers/trymatch lib). Mock<T> = T & MockInstance<T>and the required-parameter overloads — generic/overloaded call signatures preserved,spyOnreturn type unaffected.BunConsumerConvenienceMethodsmove intoBun.__internal— both global andnode:stream/webReadableStreamextend the same interface, and the fixture confirms it does not leak as a global.- The new dependency-scan test guards against a vacuous pass by asserting the exact discovered package set.
Extended reasoning...
Overview
This PR fixes eight open types issues in one change: five declaration mismatches with the runtime (Mock<T>, WebSocket error → ErrorEvent, WebView.goBack/goForward, FormData iteration, ReadableStream consumer methods with lib.dom), a reorganization of the ECMAScript-addition declarations in globals.d.ts to match TypeScript's lib files exactly (fixing core-js TS2430 conflicts and adding Map.getOrInsert), and adding undici-types as a declared dependency. It touches 5 .d.ts files in packages/bun-types/, package.json/bun.lock, the integration test, and 7 fixture files. No native or runtime JS code changes.
Security risks
None. This is purely type-declaration and test-fixture work; no executable code paths, auth, crypto, or input handling change.
Level of scrutiny
Medium-high. Although .d.ts changes carry no runtime risk, bun-types is a published npm package and its signatures are user-facing API. The PR bundles eight fixes (~720 lines added) and explicitly flags a breaking-change decision: aligning PromiseWithResolvers<T>.resolve with the lib signature makes resolve() with no argument an error for non-void T, which the author reports affects 136 sites in test/ and will affect downstream users similarly. That is a reasonable trade-off (it matches TypeScript's own lib), but it is exactly the kind of API-design call the repo's review guidance says needs maintainer agreement.
Other factors
packages/bun-types/is covered by CODEOWNERS (alii), which per my guidelines means I should not auto-approve.- The bug-hunting system found nothing; my own read of the diff agrees. The signatures line up with the lib files named in the region comments, the
Mock<T>intersection preserves generic/overloaded call signatures while keepingMockInstancemergeable, and theBun.__internalrefactor keeps the consumer-method interface out of the global namespace (fixture asserts this). - Test coverage is thorough: each fix has a dedicated fixture, the new
core-js-types.tsfixture re-declares the lib signatures to catch future drift via TS2430, use-site checks were added forfromAsync/isError/RegExp.escapeper the CodeRabbit suggestion (commit 23b590d), and the dependency-scan test asserts the exact discovered package set to avoid a vacuous pass. - The one CodeRabbit inline comment is resolved. No outstanding human review comments.
Mock<T> is now T & MockInstance<T>, and mock() and jest.fn() get an overload with a required implementation parameter, so a mock of a generic or overloaded function keeps its call signatures (#38037). The WebSocket "error" event is an ErrorEvent, which is what the runtime dispatches (#36329). Bun.WebView declares goBack() and goForward(), the names the runtime exposes, instead of back() and forward() (#30754). The global ReadableStream interface extends the same interface as the node:stream/web augmentation, so text(), json(), bytes() and blob() exist when lib.dom.d.ts is loaded too (#29401). #31757 proposed the same extension of the global interface, but placed it at the top level of overrides.d.ts, which is a module, so it never reached the global interface. Map and WeakMap declare getOrInsert() and getOrInsertComputed() with the signatures from lib.esnext.collection.d.ts (#27380). The ECMAScript additions in globals.d.ts are grouped into one region and each signature matches the TypeScript lib file it duplicates. This changes ArrayBuffer.resize() (the change from #32484) and SharedArrayBuffer.grow() (they return void), Promise.withResolvers() (it returns PromiseWithResolvers<T>), Promise.try(), Array.fromAsync() and Uint8Array.setFromBase64() (its second parameter is an options object, a number throws at runtime). A fixture re-declares the standard signatures the way core-js does and fails on any drift (#26868). bun-types imports from undici-types, so it declares it as a dependency. A test checks that every package the .d.ts files import from is declared (#22805). The FormData iterator types (#27194) are not part of this commit. #34264 fixes them.

I reviewed this PR and didn't find any bugs. Because packages/bun-types/ has a CODEOWNER and the PR flags a decision point (the Promise.withResolvers() resolve signature change) plus adds undici-types as a published dependency, a human look is still worthwhile.
What was reviewed:
- Verified
goBack/goForwardmatch the runtime names insrc/runtime/webview/;back()/forward()do not exist there. - Checked that moving
BunConsumerConvenienceMethodsintoBun.__internalkeeps it non-global (fixture/globals.ts still asserts@ts-expect-erroron the bare name) and that both the global andnode:stream/webReadableStreamextend the same shared interface. - Confirmed the
Mock<T>change from an interface call signature toT & MockInstance<T>does not remove a public merge point — the exportedMockwas already a type alias, andMockInstanceremains an interface. - Checked the ECMAScript-region signatures against the cited lib files' shapes and that the new dependency test guards itself against the glob returning nothing.
Extended reasoning...
Overview
Types-only PR closing seven bun-types issues in one pass: Mock<T> becomes T & MockInstance<T> so generic/overloaded call signatures survive; the WebSocket error event is typed as ErrorEvent; WebView.back/forward are renamed to the runtime's goBack/goForward; ReadableStream gains Bun's consumer methods with or without lib.dom via a shared Bun.__internal interface; Map/WeakMap gain getOrInsert/getOrInsertComputed; the ECMAScript augmentations in globals.d.ts are consolidated into one region and aligned byte-for-byte with the TypeScript lib files so core-js-style extenders no longer hit TS2430; and undici-types becomes a declared dependency with a test that scans every .d.ts for undeclared imports. Fourteen files changed, all .d.ts, package.json/bun.lock, or fixture/test files — no native code.
Security risks
None. Declaration files only; no runtime behavior changes. The only packaging surface is the new undici-types: "*" dependency on the published bun-types package, which the PR body analyzes (isolated vs. hoisted layouts, second-copy behavior alongside @types/node's pinned version).
Level of scrutiny
Medium. The individual fixes are straightforward and each is backed by a fixture that fails on main and passes on the branch (the evidence block shows the fail-before/pass-after for both ASAN and release). But three things push this past auto-approval:
packages/bun-types/is CODEOWNER-gated in.github/CODEOWNERS.- The PR body explicitly flags a decision ("To decide on"): aligning
withResolvers<T>()withlib.es2024.promise.d.tsmakesresolve()without a value a type error for non-voidT, which surfaces ~139 new diagnostics intest/(not type-checked in CI, but it is a user-facing tightening). - Adding a dependency to a published types package with a
*range is a packaging call the maintainer should ack.
Other factors
The one CodeRabbit suggestion (add use-site checks for RegExp.escape, Array.fromAsync, Error.isError) was applied in the last commit and the thread is resolved. The overlap with #34264, #32484, and #31757 is documented and the merge order is handled. I spot-checked goBack/goForward against src/runtime/webview/ and they match; the Bun.__internal move keeps the interface out of the global scope (fixture still asserts that); and the new "every package imported is a dependency" test guards its own emptiness with a second assertion on the found package set.
entries(), values() and [Symbol.iterator]() on FormData were typed as yielding strings. An entry appended as a blob is a File at runtime, which get() and getAll() already said. The iterators now return a FormDataIterator declared like the one in lib.dom.d.ts, so the declarations merge when that lib is loaded and iterator helpers are available without it (#27194).

Without lib.dom, Request and Response are the undici-types classes, and their formData() resolves to undici's FormData, whose iteration methods return plain iterators. With the global FormData declaring FormDataIterator (an IteratorObject) for those methods, `const form: FormData = await request.formData()` fails with TS2322 in the default configuration: the undici iterator has no [Symbol.dispose]. It failed on main too, for the previous reason (values() yielded string). The methods now return Bun.__internal.LibFormDataIteratorOrIterableIterator: lib.dom's FormDataIterator when that lib is loaded, so the declarations agree and the iterator helpers are available, and IterableIterator otherwise, which undici's iterators satisfy. The fixture checks the assignment in both directions of the body API and what the iterators yield, instead of the exact iterator type, which now differs between the two configurations. With the previous declaration, the two new functions fail in every configuration without lib.dom. Co-authored-by: 0zminDev <0zminDev@pm.me>

I reviewed this PR and didn't find any bugs. Because it bundles eight independent type fixes into one large globals.d.ts reorganization, adds undici-types as a published dependency, and — per the description's own "To decide on" note — tightens Promise.withResolvers() in a way that surfaces ~139 new errors in test/, a maintainer sign-off would still be worthwhile.
The earlier description/diff mismatch I flagged is resolved (title, Fixes line, and Related PRs now match the FormData commit).
What was reviewed:
- ECMAScript region signatures against the named lib files (
resize/grow→void,setFromBase64options-not-offset,fromAsync,withResolvers,getOrInsert) — thecore-js-types.tsfixture pins each one via TS2430. Mock<T> = T & MockInstance<T>and the required-parameter overloads — checked thatspyOn's return still flows through and that generic/overloaded implementations keep their call signatures permocks.ts.BunReadableStreamConsumerMethodsmove intoBun.__internal— the@ts-expect-error BunConsumerConvenienceMethodsguard infixture/globals.tsstill holds, andnode:stream/web↔ globalReadableStreamassignability is preserved.FormDataIteratorconditional (LibFormDataIteratorOrIterableIterator) — verified the non-DOM branch keepsawait request.formData()assignable to globalFormData(commit f2e068f's fixture).
Extended reasoning...
Overview
This PR fixes eight open types-labeled issues in one change to packages/bun-types: five runtime/declaration mismatches (Mock<T>, WebSocket error event, WebView.goBack/goForward, FormData iteration, global ReadableStream consumer methods with lib.dom), a reorganization of the ECMAScript-additions region in globals.d.ts so every signature matches TypeScript's lib files (adding Map.getOrInsert/getOrInsertComputed), and an undici-types dependency with a test that every imported package is declared. Net diff is 745+/239- across 14 files, roughly half of which is the globals.d.ts reorganization and the other half new fixture files. No native or JS runtime code is touched.
Security risks
None. This is purely .d.ts and test-fixture changes plus a package.json dependency addition. No executable code paths change.
Level of scrutiny
Medium-high. The changes are types-only, well-tested (16-test integration suite type-checks fixtures with and without lib.dom, plus a lib: [] case), and CI is green on all lanes except an unrelated darwin TLS timeout. However:
- The PR description explicitly flags a maintainer decision: aligning
withResolvers<T>()with lib.es2024.promise makesresolve()require a value whenTis notvoid, which the author measured as ~139 new tsc errors acrosstest/(not CI-checked, but affects downstream users on the same pattern). - Adding
undici-types: "*"as a direct dependency of the published package is a packaging decision — the description explains why an install-based test can't catch the missing dep, and why*matches the@types/nodeconvention, but a maintainer should confirm the*range is intentional. JestMock.Mockchanges from an interface to a type alias. The author's earlier comment addressed why this is not a declaration-merging regression (the public export was already a type alias;MockInstanceremains mergeable), but it's still a shape change to a widely-used export.
Other factors
The bug-hunting system found nothing. My earlier inline comment about the description not matching the FormData commit was addressed — the description, title, Fixes line, and Related-PRs section now list #27194, and the 07:30 dedupe comment carries a supersession note. CodeRabbit's suggestion to add use-site checks for fromAsync/isError/RegExp.escape was applied in commit e2b12b0. The one new commit since my last look (f2e068f) adds the LibFormDataIteratorOrIterableIterator conditional so that undici-types' FormData (plain IterableIterator returns) stays assignable to the global one without lib.dom, with two fixture functions guarding it.
Given the explicit "To decide on" item and the packaging/API-surface changes, deferring rather than auto-approving.

With bun's isolated linker this can install a second copy next to the one@types/nodepins (undici-types@8.10.0for bun-types and8.3.0for@types/node@26.2.0today). A project with both type-checks cleanly: bun-types'Request,Response,HeadersandEventSourcecome from its copy, and@types/nodeonly uses its copy fornode:httpexports. A hoistednode_modulesresolvesundici-typesthrough@types/node, and bun's isolated linker also hoists intonode_modules/.bun/node_modules, so an install-based test passes with or without the dependency. That is why the test reads the.d.tssources instead. A layout that links only declared dependencies, such aspackages/bun-typesin this repo, gets TS2307 in the three files above.Found while working on this and handed off separately: the global

The first version of the change here returned aFormDataIteratorcopied from lib.dom.d.ts (IteratorObject-based) in every configuration, so that the DOM case agrees with lib.dom and has the iterator helpers. A later self-review found that without lib.dom this breaksconst form: FormData = await request.formData()with TS2322:RequestandResponseare undici-types' classes there, and undici'sFormDataiterators have no[Symbol.dispose]. main fails the same assignment for another reason (values()yieldsstring), and #34264'sIterableIteratorshape passes it. The declaration now returnsFormDataIteratoronly when lib.dom is loaded (checked:new FormData().values().map(...)type-checks with lib.dom, and does not on main) andIterableIteratorotherwise, which is #34264's shape.fixture/globals.tsassigns theformData()of aRequestand of aResponsetoFormData, the way24154.tsdoes forBlob: with the first version those two lines fail in every configuration without lib.dom, andfetch.ts:11already covers aFormDataas a request body. The fixture block sits after the line that the DOM case'sglobals.ts:307diagnostic points at, so no expected line numbers move. #32484'sresize()line and the one here differ only in the parameter (byteLength: numberthere, the lib'snewByteLength?: numberhere). #31757 was checked by applying it to main: the types test passes unchanged, still expectingProperty 'text' does not exist on type 'ReadableStream<...>'in the DOM case, and a file withdeclare const s: ReadableStream; s.text()reports the same TS2339 with and without it.overrides.d.tsstarts withexport {}, so its top-levelinterface ReadableStreamis local to that module. The existingfixture/globals.tscheck thatBunConsumerConvenienceMethodsdoes not leak depends on the same fact. The same hunk insidedeclare globaldoes work, which is what this PR does inglobals.d.ts, a script file, through a shared interface so that thenode:stream/webstream stays assignable to the global one.CI on the final revision (f2e068f, Buildkite build 101270, and 2c83b4a before it, build 101128): 178 of 179 jobs passed in both.
