v0.2.100

Compare Source

Released 2025-01-12

Added

• Add attributes to overwrite return (``unchecked_return_type) and parameter types (unchecked_param_type), descriptions (return_descriptionandparam_description) as well as parameter names (js_name`) for exported functions and methods. See the guide for more details.
  #​4394

• Add a copy_to_uninit() method to all TypedArrays. It takes &mut [MaybeUninit<T>] and returns &mut [T].
  #​4340

• Add test coverage support for Node.js.
  #​4348

• Support importing memory and using wasm_bindgen::module() in Node.js.
  #​4349

• Add --list, --ignored, --exact and --nocapture to wasm-bindgen-test-runner, analogous to cargo test.
  #​4356

• Add bindings to Date.to_locale_time_string_with_options.
  #​4384

• #[wasm_bindgen] now correctly applies #[cfg(...)]s in structs.
  #​4351

Changed

• Optional parameters are now typed as T | undefined | null to reflect the actual JS behavior.
  #​4188

• Adding getter, setter, and constructor methods to enums now results in a compiler error. This was previously erroneously allowed and resulted in invalid JS code gen.
  #​4278

• Handle stuck and failed WebDriver processes when re-trying to start them.
  #​4340

• Align test output closer to native cargo test.
  #​4358

• Error if URL in <WEBDRIVER>_REMOTE can't be parsed instead of just ignoring it.
  #​4362

• Remove WASM_BINDGEN_THREADS_MAX_MEMORY and WASM_BINDGEN_THREADS_STACK_SIZE. The maximum memory size can be set via -Clink-arg=--max-memory=<size>. The stack size of a thread can be set when initializing the thread via the default function.
  #​4363

• console.*() calls in tests are now always intercepted by default. To show them use --nocapture. When shown they are always printed in-place instead of after test results, analogous to cargo test.
  #​4356

Fixed

• Fixed using JavaScript keyword as identifiers not being handled correctly.
  #​4329

  • Using JS keywords as struct and enum names will now error at compile time, instead of causing invalid JS code gen.
  • Using JS keywords that are not valid to call or access properties on will now error at compile time, instead of causing invalid JS code gen if used as:
    1. The first part of a js_namespace on imports.
    2. The name of an imported type or constant if the type or constant does not have a js_namespace or module attribute.
    3. The name of an imported function if the function is not a method and does not have a js_namespace or module attribute.
  • Using JS keywords on imports in places other than the above will no longer cause the keywords to be escaped as _{keyword}.

• Fixed passing large arrays into Rust failing because of internal memory allocations invalidating the memory buffer.
  #​4353

• Pass along an ignore attribute to unsupported tests.
  #​4360

• Use OS provided temporary directory for tests instead of Cargo's target directory.
  #​4361

• Error if URL in <WEBDRIVER>_REMOTE can't be parsed.
  #​4362

• Internal functions are now removed instead of invalidly imported if they are unused.
  #​4366

• Fixed no_std support for all APIs in web-sys.
  #​4378

• Prevent generating duplicate exports for closure conversions.
  #​4380

v0.2.99

Compare Source

Released 2024-12-07

Fixed

• Mark wasm-bindgen v0.2.98 only compatible with wasm-bindgen-cli of the same version.
  #​4331

v0.2.98

Compare Source

Released 2024-12-07

Added

• Add support for compiling with atomics for Node.js.
  #​4318

• Add WASM_BINDGEN_TEST_DRIVER_TIMEOUT environment variable to control the timeout to start and connect to the test driver.
  #​4320

• Add support for number slices of type MaybeUninit<T>.
  #​4316

Changed

• Remove once_cell/critical-section requirement for no_std with atomics.
  #​4322

• static FOO: Option<T> now returns None if undeclared in JS instead of throwing an error in JS.
  #​4319

Fixed

• Fix macro-hygiene for calls to std::thread_local!.
  #​4315

• Fix feature resolver version 1 compatibility.
  #​4327

v0.2.97

Compare Source

Released 2024-11-30

Fixed

• Fixed js-sys and wasm-bindgen-futures relying on internal paths of wasm-bindgen that are not crate feature additive.
  #​4305

v0.2.96

Compare Source

Released 2024-11-29

Added

• Added support for the HTMLOrSVGElement mixin, which is used for all interfaces deriving from Element.
  #​4143

• Added bindings for MathMLElement.
  #​4143

• Added JSDoc type annotations to C-style enums.
  #​4192

• Added support for C-style enums with negative discriminants.
  #​4204

• Added bindings for MediaStreamTrack.getCapabilities.
  #​4236

• Added WASM ABI support for u128 and i128
  #​4222

• Added support for the wasm32v1-none target.
  #​4277

• Added support for no_std to js-sys, web-sys, wasm-bindgen-futures and wasm-bindgen-test.
  #​4277

• Added support for no_std to link_to!, static_string (via thread_local_v2) and throw.
  #​4277

• Added environment variables to configure tests: WASM_BINDGEN_USE_BROWSER, WASM_BINDGEN_USE_DEDICATED_WORKER, WASM_BINDGEN_USE_SHARED_WORKER WASM_BINDGEN_USE_SERVICE_WORKER, WASM_BINDGEN_USE_DENO and WASM_BINDGEN_USE_NODE_EXPERIMENTAL. The use of wasm_bindgen_test_configure! will overwrite any environment variable.
  #​4295

Changed

• String enums now generate private TypeScript types but only if used.
  #​4174

• Remove unnecessary JSDoc type annotations from generated .d.ts files
  #​4187

• Deprecate autofocus, tabIndex, focus() and blur() bindings in favor of bindings on the inherited Element class.
  #​4143

• Optimized ABI performance for Option<{i32,u32,isize,usize,f32,*const T,*mut T}>.
  #​4183

• Deprecate --reference-types in favor of automatic target feature detection.
  #​4237

• wasm-bindgen-test-runner now tries to restart the WebDriver on failure, instead of spending its timeout period trying to connect to a non-existing WebDriver.
  #​4267

• Deprecated #[wasm_bindgen(thread_local)] in favor of #[wasm_bindgen(thread_local_v2)], which creates a wasm_bindgen::JsThreadLocal. It is similar to std::thread::LocalKey but supports no_std.
  #​4277

• Updated the WebGPU API to the current draft as of 2024-11-22.
  #​4290

• Improved error messages for self arguments in invalid positions.
  #​4276

Fixed

• Fixed methods with self: &Self consuming the object.
  #​4178

• Fixed unused string enums generating JS values.
  #​4193

• Fixed triggering lints in testing facilities.
  #​4195

• Fixed #[should_panic] not working with #[wasm_bindgen_test(unsupported = ...)].
  #​4196

• Fixed potential null error when using JsValue::as_debug_string().
  #​4192

• Fixed generated types when the getter and setter of a property have different types.
  #​4202

• Fixed generated types when a static getter/setter has the same name as an instance getter/setter.
  #​4202

• Fixed invalid TypeScript return types for multivalue signatures.
  #​4210

• Only emit table.fill instructions if the bulk-memory proposal is enabled.
  #​4237

  #​4241

• Fixed imports for functions using this and late binding.
  #​4225

• Don't expose non-functioning implicit constructors to classes when none are provided.
