Release Notes

wasm-bindgen/wasm-bindgen (wasm-bindgen)

v0.2.114

Compare Source

Added

• Added unchecked_optional_param_type attribute for marking exported function parameters as
  optional in TypeScript (?:) and JSDoc ([paramName]) output. Mutually exclusive with
  unchecked_param_type. Required parameters after optional parameters are rejected at compile time.
  #​5002

• Added termination detection for panic=unwind builds. When a non-JS exception (e.g. a Rust
  panic) escapes from Wasm, the instance is marked as terminated and subsequent calls from JS
  into Wasm will throw a Module terminated error instead of re-entering corrupted state.
  #​5005

• When --reset-state is combined with panic=unwind builds, the Wasm instance is
  automatically reset after a fatal termination, allowing subsequent calls to succeed
  instead of throwing a Module terminated error.
  #​5013

Changed

• Replaced runtime 0x80000000 vtable bit-flag for closure unwind safety with a
  compile-time const UNWIND_SAFE: bool generic on the invoke shim, OwnedClosure,
  and BorrowedClosure. Removes OwnedClosureUnwind and deduplicates internal
  closure helpers. The public API is unchanged.
  #​5003

• Removed unused IntoWasmClosureRef*::WithLifetime types,
  WasmClosure::to_wasm_slice, and a lifetime from
  IntoWasmClosureRef*; moved Static associated type into WasmClosure.
  #​5003

Fixed

• Fixed exported structs/enums/functions with the same js_name but different
  js_namespace values producing symbol collisions at compile time, by deriving
  internal wasm symbols from a qualified name that includes the namespace.
  #​4977

• Fixed soundness hole in ScopedClosure's UpcastFrom that allowed to extend the lifetime after the original ScopedClosure was dropped.
  #​5006

v0.2.113

Compare Source

Changed

• Reduced usage of unsafe code: replaced transmute/transmute_copy with safe
  alternatives for Boolean/Null/Undefined constants and ArrayTuple conversions,
  unified duplicated AsRef/From impls for generic imported types, and removed the
  __wbindgen_object_is_undefined intrinsic in favor of a safe Rust-side equivalent.
  #​4993

• Renamed __wbindgen_object_is_null_or_undefined intrinsic to
  __wbindgen_is_null_or_undefined and removed the __wbindgen_object_is_undefined
  intrinsic, replacing it with a safe Rust-side check. The is_null_or_undefined check
  now uses safe &JsValue ABI instead of raw u32.
  #​4994

Fixed

• Fixed incorrect method naming for stable web-sys methods that reference unstable
  types (e.g. texImage2D taking a VideoFrame parameter). These methods were
  being named in a separate unstable expansion namespace, producing overly-short
  names like tex_image_2d instead of the correct
  tex_image_2d_with_u32_and_u32_and_video_frame. The fix separates the signature
  classification to distinguish "from unstable IDL" (authoritative overrides) from
  "stable method using an unstable type", ensuring the latter is named as part of
  the stable expansion.
  #​4991

v0.2.112

Compare Source

Removed

• Removed ImmediateClosure type introduced in 0.2.109. Stack-borrowed &dyn Fn / &mut dyn FnMut
  closures are now treated as unwind safe by default (panics are caught and converted to JS exceptions
  with proper unwinding). A unified ScopedClosure::immediate approach may be revisited in a future
  release.
  #​4986

v0.2.111

Compare Source

Fixed

• Restored backwards compatibility for breaking changes introduced in 0.2.110:
  re-added deprecated Promise::then2 binding, reverted Promise::all_settled
  stable signature to take &JsValue instead of owned Object, and added
  default type parameters (= JsValue) to ArrayIntoIter, ArrayIter, and
  Iter structs.
  #​4979

v0.2.110

Compare Source

Changed

• Refactor new closure methods - ensures that all closure constructor functions have the variants Closure::foo(), Closure::foo_aborting() and
  Closure::foo_assert_unwind_safe() this then fully allows switching from the UnwindSafe bound now being applies on foo() to use one of the
  alternatives, given these limitations of AssertUnwindSafe. The same applies to ImmediateClosure. In addition, mutable reentrancy guards are
  added for ImmediateClosure, and it is updated to be pass-by-value as well.
  #​4975

Fixed

• Fixed a regression where Array.of1,... variants using generic Array<T> broke inference.
  Reverted to use non-generic JsValue arguments. In addition extends generic class hoisting to
  for constructors to also include static_method_of methods returning the own type, to allow
  Array::of generic to now be on the Array<T> impl block.
  #​4974

v0.2.109

Compare Source

Added

• Added support for erasable generic type parameters on imported JavaScript types,
  using sound type erasure in JS bindgen boundary. Includes updated js-sys bindings
  with generic implementations for many standard JS types and functions including
  Array<T>, Promise<T>, Map<K, V>, Iterator<T>, and more.
  #​4876

• Added ScopedClosure<'a, T> as a unified closure type with lifetime parameter. ScopedClosure::borrow(&f) (for immutable Fn) and ScopedClosure::borrow_mut(&mut f) (for mutable FnMut) create borrowed closures that can capture non-'static references, ideal for immediate/synchronous JS callbacks. Closure<T> is now a type alias for ScopedClosure<'static, T>, maintaining backwards compatibility. Also added IntoWasmAbi implementation for Closure<T> enabling pass-by-value ownership transfer to JavaScript.

• Added ImmediateClosure<'a, T> as a lightweight, unwind-safe replacement for
  &dyn FnMut in immediate/synchronous callbacks. Unlike ScopedClosure, it has
  no JS call on creation, no JS call on drop, and no GC overhead—the same ABI as
  &dyn FnMut but with panic safety. Use ImmediateClosure::new(&f) for
  immutable Fn closures (easier to satisfy unwind safety) or ImmediateClosure::new_mut(&mut f) for
  mutable FnMut closures. Closure parameter types are automatically inferred from context.
  Also implements From<&ImmediateClosure<T>> for ScopedClosure<T> for API migration.
  #​4950

• Implement #[wasm_bindgen(catch)] exception handling directly in Wasm using
  WebAssembly.JSTag when Wasm exception handling is available. This generates
  smaller and faster code by avoiding JavaScript handleError wrapper functions.
  #​4942

• Add Node.js worker_threads support for atomics builds. When targeting Node.js with atomics enabled, wasm-bindgen now generates initSync({ module, memory, thread_stack_size }) and __wbg_get_imports(memory) functions that allow worker threads to initialize with a shared WebAssembly.Memory and pre-compiled module. Auto-initialization occurs only on the main thread for backwards compatibility.

• Added a panic message when a getter has more than one argument.
  #​4936

• Added support for WebIDL namespace attributes in wasm-bindgen-webidl. This enables
  APIs like the CSS Custom Highlight API which adds the highlights attribute to the CSS namespace.
  #​4930

• Added stable ShowPopoverOptions dictionary and show_popover_with_options() method to
  HtmlElement, and unstable TogglePopoverOptions dictionary per the WHATWG HTML spec.
  #​4968

• Added unstable Geolocation API types per the latest W3C spec: GeolocationCoordinates,
  GeolocationPosition, and GeolocationPositionError. The Geolocation interface now
  has both stable methods (using the old Position/PositionError types with [Throws])
  and unstable methods (using the new types without [Throws]}, matching actual browser behavior).
  #​2578

• Added matrixTransform() method to DOMPointReadOnly in web-sys.
  #​4962

• Added the web and node targets to the --experimental-reset-state-function flag.
  #​4909

• Added oncancel event handler to GlobalEventHandlers (available on HtmlElement,
  Document, Window, etc.).
  #​4542

• Added CommandEvent and CommandEventInit from the Invoker Commands API.
  #​4552

• Added AbstractRange, StaticRange, and StaticRangeInit interfaces.
  #​4221

• Updated WebCodecs API to Working Draft 2026-01-29 and MediaRecorder API to 2025-04-17.
  Added rotation and flip to VideoDecoderConfig.
  #​4411

• Added support for unstable WebIDL to override stable attribute types, allowing
  corrected type signatures behind web_sys_unstable_apis. Applied to MouseEvent
  coordinate attributes (clientX, clientY, screenX, screenY, offsetX,
  offsetY, pageX, pageY) which now return f64 instead of i32 when
  unstable APIs are enabled, per the CSSOM View spec draft.
  #​4935

• Added support for unstable WebIDL to override stable method return types. This
  enables User Timing Level 3 APIs where Performance.mark() and Performance.measure()
  return PerformanceMark and PerformanceMeasure respectively (instead of undefined)
  when web_sys_unstable_apis is enabled. Also added PerformanceMarkOptions,
  PerformanceMeasureOptions, and the detail attribute on marks/measures.
  #​3734

• Added non-standard mode option for FileSystemFileHandle.createSyncAccessHandle().
  Also improved WebIDL generator to track stability at the signature level, allowing
  stable methods to have unstable overloads.
  #​4928

• Updated WebGPU bindings to the February 2026 spec. Dictionary fields with union
  types now generate multiple type-safe setters (e.g. set_resource_gpu_sampler(),
  set_resource_gpu_texture_view()) alongside a deprecated fallback setter. Sequence
  arguments in unstable APIs now use typed slices (&[T]) instead of &JsValue.
  Fixed inner string enum types to use JsString in generic positions, added BigInt
  to builtin identifiers, and fixed dictionary field feature gates to not over-constrain
  getters with setter type requirements.
  #​4955

• Improved dictionary union type expansion: stable fallback setters are no longer
  deprecated, and unstable builder methods now use the first typed variant instead
  of &JsValue. Dictionaries with required union fields now generate expanded
  constructors for each variant (e.g. new(), new_with_gpu_texture_view()),
  with duplicate-signature variants elided.
  #​4966

Changed

• Increased externref stack size from 128 to 1024 slots to prevent "table index is out of bounds"
  errors in applications with deep call stacks or many concurrent async operations.
  #​4951

• Closure::new(), Closure::once(), and related methods now require UnwindSafe bounds on closures when building with panic=unwind. New _aborting variants (new_aborting(), once_aborting(), etc.) are provided for closures that don't need panic catching and want to avoid the UnwindSafe requirement.
  #​4893

• global does not use the unsafe-eval new Function trick anymore allowing to have CSP strict compliant packages with wasm-bindgen.
  #​4910

• eval and Function constructors are now gated behind the unsafe-eval feature.
  #​4914

Fixed

• Fixed incorrect JS export names when LLVM merges identical functions at opt-level >= 2.
  #​4946

• Fixed incorrect Closure adapter deduplication when wasm-ld's Identical Code Folding merges
  invoke functions for different closure types into the same export.
  #​4953

• Fixed ReferenceError when using Rust struct names that conflict with JS builtins (e.g., Array).
  The constructor now correctly uses the aliased FinalizationRegistry identifier.
  #​4932

• Fixed Element::scroll_top(), Element::scroll_left(), and HtmlElement::scroll_top()
  to return f64 instead of i32 per the CSSOM View spec, behind web_sys_unstable_apis.
  The stable API is unchanged for backwards compatibility.
  #​4525

• Added spec-compliant i32 parameter types for CanvasRenderingContext2d::get_image_data()
  and put_image_data() (and OffscreenCanvasRenderingContext2d equivalents) behind
  web_sys_unstable_apis. Per the HTML spec, getImageData and putImageData use long
  (i32) for coordinates, not double (f64). The stable API is unchanged for backwards
  compatibility.
  #​1920

• Fixed incorrect #[cfg(web_sys_unstable_apis)] gating on stable method signatures that
  share a WebIDL operation with unstable overloads. For example, Clipboard.read() (0 args)
  was incorrectly gated as unstable because the unstable read(options) overload existed.
  The WebIDL code generator now uses an authoritative expansion model where stable and unstable
  signature sets are built independently and compared: identical signatures merge (no gate),
  stable-only signatures get not(unstable), and unstable-only signatures get unstable.
  Also adds typed generics (Promise<T>, Array<T>, Function<fn(...)>, etc.) to all
  unstable API methods, and adds missing PhotoCapabilities, PhotoSettings,
  MediaSettingsRange, Point2D, RedEyeReduction, FillLightMode, and MeteringMode
  types from the W3C Image Capture spec.
  #​4964

• Fixed unfulfilled_lint_expectations warnings when using #[expect(...)] attributes
  on functions annotated with #[wasm_bindgen]. The #[expect] attributes are now
  converted to #[allow] in generated code to prevent spurious warnings.
  #​4409
