webapi v0.5.0

Changes

• Make spec field immutable in AST types
• Refactor peek_kind/peek2_kind/peek3_kind
• update to moonbit v0.9.0

v0.4.8

What's Changed

• Move trim back to webapi/trim package (was incorrectly split into separate module)
• Fix CI workflow paths for workspace restructure
• Move gen to separate webapi-gen workspace module
• Add try_catch(on_ok, on_err) for uniform error recovery across JS and wasm-gc targets (#19)
• Sort generated spec comments for deterministic codegen output
• Implement Show trait for ArgMbtType and Filename
• Fix build output paths for MoonBit v0.9

v0.4.7

What's Changed

• Add try_catch(on_ok, on_err) utility for uniform error recovery across JS and wasm-gc targets (#19)
  • JS: catches abort, panic, and raise errors
  • wasm-gc: catches raise errors and JS exceptions (abort traps are unrecoverable by wasm spec)
• Sort generated spec comments for deterministic codegen output

v0.4.6

What's Changed

• Implement Show trait for ArgMbtType and Filename
• Upgrade to MoonBit v0.9
• Move gen and trim to separate workspace modules (webapi-gen, webapi-trim)
• Update build paths for new moon workspace layout
• Fix flaky HashSet ordering in tests

v0.4.5

Added

• Added JS minification to the trim tool, enabled by default. Strips comments, collapses whitespace, and preserves string/template literal contents. Use --no-minify to disable.

Changed

• Trim tool size reporting now shows bytes instead of line counts.

v0.4.4

Changed

• Moved examples from src/examples/ to examples/ at project root, removing the symlink.

Fixed

• Fixed wasm-gc externref mismatch for CSSOMString returns (#18). The code generator now uses jsvalue_to_string() for string alias types instead of unsafe_cast(), which produced invalid wasm when converting nullable externref to non-nullable (ref extern).

v0.4.3

Added

• Added checked downcast method try_into() on all generated interface types, returning T? with a runtime instanceof check.
• Added HasConstructor trait and js_instanceof() FFI to support runtime type checks on both JS and wasm-gc targets.
• Added JsObject::get() method for dynamic property access, complementing the existing set().

Changed

• Renamed the unchecked downcast from into() to unsafe_into() to clarify intent.

Deprecated

• Deprecated into() in favor of try_into() (safe) or unsafe_into() (explicit unchecked).

Fixed

• Fixed deprecated into() call in JsValue::as_string template.
• Removed accidentally committed dotfiles and stray entries.

v0.4.2

Changed

• Restructured repository to use a single root moon.mod.json with "source": "src".
• Renamed webapi/ to src/, webapi_gen/ to src/gen/, webapi_trim/ to src/trim/.
• Moved examples/ to src/examples/ with a root-level symlink for navigation.
• Flattened src/gen/cmd/main/ into src/gen/.
• Unified all MoonBit packages under one module; src/gen/ excluded from publishing.
• Simplified Makefile and CI for single-module layout.
• Sped up trim by building once and running via node instead of moon run per file.

Fixed

• Added wasm-tools install step to CI for wasm-gc binary validation.
• Fixed Playwright tests 404 by using src/examples/ path instead of symlink.

Removed

• Removed .githooks/ and .claude/ from version control.

v0.4.1

Fixed

• Updated the generated global browser accessors to use document(), window(), and navigator() consistently across the package and docs.
• Fixed the example gallery and example builds after the global accessor API change so make build-examples passes again.

Changed

• Simplified webapi_gen/base.mbt by merging backend-specific *_js.mbt and *_wasm.mbt template files into unified #cfg(...)-gated base templates.

Full Changelog: v0.4.0...v0.4.1

v0.4.0

Highlights

• Added first-class wasm-gc support alongside the existing JS target.
• Expanded the live demo gallery to 45 examples covering DOM, Fetch, Canvas, Streams, IndexedDB, Web Animations, WebSocket, URLPattern, File System Access, custom elements, and more.
• Broadened generated API coverage with variadic arguments, namespaces, special operations, more specs, richer dictionary support, and improved callback ergonomics.
• Added webapi_trim, a CLI/tooling path for trimming webapi.mjs to only the modules required by a compiled wasm binary.

Breaking Changes

• Promise-returning APIs now use JsPromise[T] instead of @js_async.Promise[T].
• For JS-only async/await integration, use the bikallem/webapi/js_promise bridge package to convert JsPromise[T] values.

Added

• Added JsPromise[T] support for both JS and wasm-gc, including then(), catch_(), and finally_() helpers plus the webapi/js_promise bridge package.
• Added webapi_trim for producing minimal webapi.mjs bundles from wasm imports, including function-level trimming and test coverage.
• Added new bindings and examples across a wide range of APIs, including Console, timers, storage, clipboard, notifications, WebSocket, fullscreen, screen orientation, requestIdleCallback, pointer/touch/selection/resize/intersection observers, streams, IndexedDB, Web Animations, permissions, service workers, URLPattern, File System Access, Trusted Types, and more.
• Added custom element helpers and examples such as wc-counter, wc-edit-word, and the larger wc-todo / wc-calculator examples.
• Added generator support for WebIDL namespaces, variadic arguments, special operations (getter/setter/deleter), dictionary getters, dynamic JsObject helpers, and additional overload handling.

Changed

• The generated bindings now target both backends throughout the pipeline, and backend-specific FFI is emitted through unified source files guarded with #cfg(...).
• The project layout was consolidated around the webapi/ module, with package metadata, examples, and tests updated to match.
• The examples gallery, GitHub Pages deployment, and local development flow were expanded to support both JS and wasm-gc demos.
• Generated runtime and emitters were refactored substantially to reduce duplication, improve determinism, and make backend behavior easier to reason about.

Fixed

• Fixed multiple wasm-gc conversion issues, including callback wrapping, nullable returns, string handling, enum conversion, primitive array decoding, and UInt64/Int64 BigInt bridging.
• Fixed generated JS runtime issues around reserved words, hyphenated CSS property names, overloaded method name collisions, and namespace module key casing.
• Fixed bugs in example behavior and encapsulation, including per-instance component state and broader JS/wasm parity across demos.
• Fixed webapi_trim robustness issues, including UTF-8 import decoding, structured parse failures, resilient filtering, and proper non-zero CLI exits on fatal errors.
• Fixed several generator correctness issues around dictionary inheritance gaps, stale output reconciliation, lexer position tracking, and nullable method/attribute conversion.

Quality and Tooling

• Grew end-to-end browser coverage to 339 Playwright tests across the example gallery.
• Added broader CI coverage for JS and wasm-gc checks, example builds, Pages deployment, and webapi_trim.
• Reworked large parts of the generator and parser internals to use smaller helpers, more deterministic output, and more MoonBit-idiomatic patterns.
