Bump every package version to 1.0.0-alpha.4 (PyPI 1.0.0a4) and promote the
CHANGELOG [Unreleased] section to 1.0.0-alpha.4. Refresh the tracked lockfile.
App download links are intentionally left at 1.0.0-alpha.3 (desktop app
release lands separately).
- version 1.0.0-alpha.3 across the workspace, Python, and Node packages
(and the vtracer dep pins, install snippets, and docs.rs link)
- CHANGELOG: date the section; note the new vtracer-bench crate and the
watershed blurred-crack filament fix
(Supersampling was explored after alpha.2 and reverted -- it did not
improve output enough to keep.)
- version 1.0.0-alpha.2 across the workspace, Python, and Node packages
- CHANGELOG: date the unreleased section
- README: bump install snippets and docs.rs link
Workspace, vtracer-py, and the nodejs wasm crate move from edition 2021
to 2024 (no code changes needed — clean build and test run on 1.95).
Module directories switch from foo/mod.rs to the modern foo.rs layout;
single-file modules (svg, optimize, compose, fitter) collapse from
directories into plain files. Pure git renames, history preserved.
image-webp is pure Rust and compiles to wasm32; brings the npm
package's input formats closer to the CLI/Python surface. Wasm grows
~115 KB (486 KB -> 601 KB). Also gitignore nodejs/.npmrc.

New nodejs/ package: a wasm-bindgen crate (vtracer-wasm) built with wasm-pack
that wraps the vtracer framework, plus a thin JS layer for file I/O. Image
decoding (png/jpeg/gif/bmp via the image crate) runs in wasm too, so the
package has zero native dependencies — no sharp, no node-gyp.
No separate general-purpose wasm crate: the Node package directly owns and
wraps the wasm. Excluded from the cargo workspace (wasm-bindgen cdylib), built
with wasm-pack.
JS API (camelCase options): convertBuffer, convertPixels, convertFile,
convertFileSync — each taking an Options object (preset, colorMode,
hierarchical/cutout mosaic, mode, palette, maxColors, optimize, ...). Ships
index.d.ts types and a node smoke test. README updated.
Verified: builds to wasm32-unknown-unknown; `node test.js` passes; output
matches the CLI/Python bindings (253 paths on the tank sample).
