v0.17.3

OXC 0.17.3

v0.17.2

Added

• OXC.Bundle.Output now exposes Rolldown module_ids for generated chunks, enabling downstream tools to map emitted chunks back to source modules.

v0.17.1

Added

• Add :dynamic_import_templates selector for template-literal dynamic import(...) expressions.
• Add :require_calls selector for CommonJS require("...") calls.

v0.17.0

Breaking changes

• Remove OXC.imports/2, OXC.imports!/2, OXC.collect_imports/2, and OXC.collect_imports!/2; use OXC.select/3 with selector atoms instead.

Added

• Add OXC.select/3 for compact parser-backed event selection.
• Add selector atoms for import sources, import specifiers, asset URLs, workers, glob imports, and import.meta.env references.

Changed

• OXC.rewrite_specifiers/3 now uses parser-backed selector events internally.
• Native import/source-reference selection now uses the shared rustler_match_spec crate.

Fixed

• Recognize generated {}.url bases when selecting worker URL references from bundled output.

v0.16.0

Added

• Add OXC.Bundle, a composable bundling pipeline that returns all Rolldown chunks and assets from multi-entry builds.
• Add bundle output metadata for generated chunks, assets, imports, dynamic imports, exports, sourcemaps, and optional output paths.

Changed

• Upgrade Rolldown bundling dependencies to 1.1.
• Decode native options directly from BEAM maps instead of routing through serde_json.

Fixed

• Prevent serde_json::Number internals from leaking into parsed AST terms when dependencies enable arbitrary-precision JSON numbers.
• Fix code generation for if statements with nil alternate branches.

v0.15.1

Fixed

• OXC.Lint.run/2 now reports nonzero tsgolint exits with stderr output, including panics from unsupported input files, instead of treating empty or malformed output as a clean type-aware lint result.

Links

• Hex package: https://hex.pm/packages/oxc/0.15.1
• Documentation: https://hexdocs.pm/oxc/0.15.1

Includes precompiled NIF archives for parser/bundler, lint, and formatter targets.

v0.15.0

Added

• Added type-aware TypeScript linting via OXC.Lint.run/2 with type_aware: true, powered by tsgolint headless mode.
• Supports type_check, source_overrides, fixes, suggestions, and normalized diagnostics for type-aware runs.

OXC.Lint.run(["lib/app.ts"],
  type_aware: true,
  tsgolint: "tsgolint",
  type_check: true,
  rules: %{"typescript/no-floating-promises" => :deny}
)

v0.14.0

Added

• Source-taking APIs now accept iodata() across parse, transform, minify, import collection, lint, format, source patching, and virtual bundle inputs.

Changed

• OXC.patch_string/2 now builds patched output with iodata internally before flattening once.
• Virtual bundle file sources are streamed from iodata directly into temporary files instead of being flattened first.

Fixed

• Lint category filters (for example, "correctness" => :deny) now return the configured severity instead of always :warn.

v0.13.0

Added

• module_types option for OXC.bundle/2 — map file extensions to loaders (:empty, :dataurl, :base64, :binary, :text, :css, :asset, etc.). Unblocks bundling packages that import binary files like fonts from CSS.

Changed

• Upgraded OXC crates from 0.129 to 0.130.
• Removed unused Cargo dependencies (oxc_resolver, oxc_transformer_plugins).
• mix lint / mix ci now checks clippy and rustfmt for all three NIF crates.

Fixed

• Resolved all clippy warnings under -D warnings.

v0.12.1

Fixed

• OXC.bundle/2 with sourcemap: true no longer fails when Rolldown omits the source map for empty bundle output (#4).
