Changes & Reason

Changes

  • Added CommonJS (cjs) support alongside the existing ES Module build.
  • Updated the Vite build configuration to generate:
    • Browser builds: es, cjs, umd, and iife
    • Node builds: es and cjs
  • Updated package.json to expose both require() and import() entry points.
  • Updated the main field to point to the CommonJS entry.

Reason

The JavaScript package was previously ESM-only, which caused compatibility issues for consumers using CommonJS environments (require()), older tooling, and some SSR setups.

This change introduces dual-module support while preserving browser compatibility.


Related Issues

Fixes: #483


Testing & Verification

  • ✅ Browser build completes successfully.
  • ✅ Node build completes successfully.
  • ✅ Browser outputs:
    • img2num.es.js
    • img2num.cjs
    • img2num.umd.js
    • img2num.iife.js
  • ✅ Node outputs:
    • index.js
    • index.cjs
  • ✅ React example runs successfully after the changes.
  • ✅ Verified both ESM and CommonJS entry points are exposed through package.json.

Additional Resources

Note

For the Node SSR build, Vite currently emits index.js and index.cjs instead of img2num.es.js and img2num.cjs.

As discussed in the issue, this appears to be related to Vite's SSR library output. I'm opening this as a Draft Pull Request so we can discuss the preferred approach for the Node output filenames before finalizing the implementation.


The below is for Release Please. This PR edited the .gitignore for the Python package, which is making it want to release v0.4.0 for the Python package, which is wrong.

Walkthrough

The JavaScript package now builds browser, standalone, Node ESM, and Node CJS outputs. The repository adds separate console examples, generated HTML examples, and an Example Apps documentation page.

Changes

JavaScript distribution and examples

Layer / File(s) Summary
WASM and package build outputs
bindings/js/CMakeLists.txt, packages/js/package.json, packages/js/src/wasmModule.js, packages/js/vite.config.js
The build produces separate WASM and JavaScript targets. Package exports cover browser, standalone, Node ESM, and Node CJS outputs. Optional WebGPU failures fall back to CPU execution.
Console example variants
Justfile, pnpm-workspace.yaml, example-apps/console-js-cjs/*, example-apps/console-js-esm/*
Console commands and workspace entries distinguish CommonJS and ESM examples. The examples convert image pixels to SVG.
HTML example build pipeline
example-apps/html-js/package.json, example-apps/html-js/scripts/*, example-apps/html-js/template.html, example-apps/html-js/variants/*
A Node build script generates ESM, IIFE, and UMD HTML examples from shared templates and variant configurations.
HTML example runtime
example-apps/html-js/shared/*, example-apps/html-js/README.md
Shared image-processing interactions, styling, documentation, and input handling support the generated HTML examples.
Documentation and development integration
docs/src/pages/example-apps/*, docs/src/pages/index.jsx, docs/docs/js/requirements.md, docs/scripts/prebuild.mjs, docker-compose.yml, Dockerfile.dev, .prettierignore, docs/.gitignore, docs/src/css/custom.css, packages/py/img2num/.gitignore
The documentation adds an Example Apps catalog, documents runtime and packaging requirements, updates deployment generation and navigation, and updates development ports and generated-file exclusions.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to 18892

The PR adds multiple JavaScript module formats, but the documentation does not fully match the published artifact set, and two ignore-pattern issues could allow generated files to remain tracked. The change is mergeable with explicit owner awareness and follow-up on these bounded documentation and repository-hygiene risks.

Hi. After looking into this more deeply, I realized that the solution here is more complex than I first thought.

Since the WebAssembly bindings currrently export in ES6 format, we will need to update that before this type of feature can be shipped because it just won't work unless we do that.😭😭

I'm sorry for messing you around a bit. I'd like to do a bit of research on the solution first, then get back to you on it. So far, the solution you've proposed looks great, but I can't assume that you know how CMake and C work, so you'll probably need to work on this solution with someone else.

Basically, the packages/js/build-wasm folder needs to get an output with ES6 and CommonJS files for this feature to work properly. The issue is that the final solution here will likely not be trivial, so I need to look into it and find the best way forwards.

Thank you again for the interest in contributing! I will be back with an answer as soon as possible. Have a nice day!🦔🦔

Hi. An update from my side: this is quite a huge change that affects a lot of things and I was very wrong to think that someone new to Img2Num could implement it. I'm extremely sorry for mislabeling #483 as a good first issue.

Thank you for your patience, though. :)

On my machine, I have managed to create a small-ish setup that effectively sets up what #483 calls for, but I still need to test it and verify that things work. I have also created a few example apps that are intended to test that the library functions correctly.

The main changes that needed to be made:

WebAssembly (build-wasm/)

bindings/js/CMakeLists.txt needed to be updated to produce different builds for each target (esm vs cjs vs umd vs iife and node vs browser).

It had to be updated to produce differing outputs for each target:

ryan@Ryans-PC:~/projects/Img2Num$ tree packages/js/build-wasm/
packages/js/build-wasm/
├── node
│   ├── img2num.js
│   └── img2num.wasm
├── standalone
│   └── img2num.js
└── web
    ├── img2num.js
    └── img2num.wasm

4 directories, 5 files
  • web targets the browser
  • node is for Node.js builds
  • standalone is for iife and umd. It needs to be a single file because they don't support multiple files. As a result, the standalone/img2num.js must have the WebAssembly embedded inside of it.

Package (dist)

Following the same naming convention as we used for the WebAssembly outputs, we have browser, node, and standalone.

On top of that, we had to do this:

  • browser
    • ES module support (all the files there are ESM)
  • node
    • ES module support (*.js)
    • CommonJS support (*.cjs)
  • `standalone
    • iife support (*.iife.*)
    • umd support (*.umd.*)

The files also include the corresponding *.map files. We may decide to remove them for standalone, but that's not really important right now.

ryan@Ryans-PC:~/projects/Img2Num$ tree packages/js/dist/

    ├── img2num.iife.js
    ├── img2num.iife.js.map
    ├── img2num.umd.js
    └── img2num.umd.js.map

4 directories, 16 files

With all that being done, I'd like to know if you'd still be willing to collaborate with me on the fix for this issue. The changes I've made still need a lot of testing and it would be great to have someone else help with the debugging.

If you're still keen, may I push my changes to your branch?

Thanks again for the assistance with this issue. We really do appreciate it!🦔

Emscripten glue shape must match output format: ES6 glue emits top-level
await and import.meta, which UMD/IIFE cannot carry, and CJS-shaped glue
reads __dirname, which ESM lacks. One glue feeding four consumption modes
could not satisfy any of them correctly.

Build three wasm variants (web, standalone, node) and emit five bundles:
- Browser:
  1. ESM

- Standalone with the WebAssembly inlined via SINGLE_FILE flag:
  2. IIFE
  3. UMD

- Node with `platform: "node"` so Rolldown resolves require()
  through createRequire, and inject __dirname/__filename into the
  node ESM output.
  4. ESM
  5. CJS

Prevent Vite from inlining the wasm as a data URL in the browser and node
bundles, cutting the browser entry from 900 kB to 108 kB.

Reduce INITIAL_MEMORY from 2GB to 32MB (a 2GB reservation fails outright
on mobile Safari and buys nothing with ALLOW_MEMORY_GROWTH), and restrict
STACK_OVERFLOW_CHECK to Debug builds.

BREAKING CHANGE: dist layout and filenames have changed. Artifacts now
live at dist/browser/img2num.js, dist/standalone/img2num.{umd,iife}.js,
and dist/node/img2num.{js,cjs}; deep imports into dist/ must be updated.
Package exports conditions have been reordered so that bundlers targeting
the browser resolve the browser build — they previously matched "import"
first and received the node build. Minimum supported Node is now 18.
…and umd

The new multi-format JavaScript build emits five artifacts, but only two
had a consumer exercising them.
These apps load each artifact the way a real consumer
would, so a bundle that builds cleanly but cannot initialize is caught by
running something rather than by reading the bundle.

Split console-js into console-js-cjs and console-js-esm, since one app
cannot exercise both the "require" and "import" export conditions. Add
html-js-iife, which loads the standalone build from a bare <script> tag
with no bundler, and html-js-umd, which loads the same build through
RequireJS to exercise the AMD branch of the UMD wrapper.

chore(Example Apps): replace the console-js recipe with console-js-cjs and console-js-esm

build(Docker): expose ports 5175-5176 for the new browser example apps

Hi @Ankurrr27. I'm sorry for the late reply - I discovered a bug in the release workflow that failed on our Python library's v0.2.2 and have been trying to fix that.

I don't think there is too much more to be done here. We just need to test it and make sure it is adequately documented.

For the testing, please will you pull the changes I made and verify that everything works for you. The examples apps should run on every device, so confirmation that it runs on your computer would be great.

For the documentation, we need to update the packages/js/README.md to mention that we now support all of the targets that we build into the build folder (esm for browser, cjs and esm for node, and iife and umd). We should do the same in our documentation.

Another thing that I'd like to also mention is that we should probably consider supporting TypeScript, but it depends heavily on the overall workload that would go into such a feature. We don't want to spend a lifetime maintaining a TypeScript library, so it would need to be simple.

I chose not to include it in this feature because it was out of scope for the issue and also would take more effort because another special build would need to be configured.

In `@docs/src/pages/example-apps/index.jsx`:
- Around line 203-206: Update the GitHub Link URL in the example-apps card
rendering to use the defined app.dir property instead of app.repoDir, while
preserving the existing repository path structure and displayed
example-apps/{app.dir} label.

In `@example-apps/console-js-cjs/index.cjs`:
- Line 20: Update the Uint8ClampedArray construction in
example-apps/console-js-cjs/index.cjs at lines 20-20 to include data.byteOffset
and data.byteLength alongside data.buffer, preserving the Sharp Buffer view
bounds. Apply the same change in example-apps/console-js-esm/index.mjs at lines
16-16; both sites require direct updates.

In `@example-apps/console-js-cjs/package.json`:
- Line 7: Update the start script in package.json to instruct users to run just
console-js-cjs with the image-path argument instead of just console-js-esm,
while preserving the existing message format.

In `@example-apps/console-js-esm/index.mjs`:
- Line 8: Update the usage message in the console entrypoint to reference
index.mjs instead of index.js, while preserving the existing image-path argument
format.

In `@example-apps/html-js/package.json`:
- Around line 6-8: Align the package scripts around a single documentation
deployment path by removing the postbuild shell copy in package.json and
ensuring the documentation workflow invokes the existing build:deploy script.
Preserve the regular build script for normal builds and use the deploy output
path that matches generated canonical URLs.

In `@example-apps/html-js/scripts/build.mjs`:
- Around line 17-21: Update the rootDir initialization near createRequire to
derive the script directory from import.meta.url using the existing Node.js path
utilities, replacing the Node.js 20-only import.meta.dirname property while
preserving the resolved parent-directory behavior.

In `@example-apps/html-js/shared/app.js`:
- Around line 7-25: Update processImage to track a monotonically increasing
request identifier for each conversion, and capture the current identifier
before awaiting imageToUint8ClampedArray and imageToSvg. Only apply the
generated preview and hide the spinner in finally when that identifier is still
the latest request, so stale conversions cannot affect the newer image or
loading state.

In `@example-apps/html-js/shared/styles.css`:
- Around line 7-8: Update the --font-sans and --font-mono custom properties in
the stylesheet to use lowercase casing for Tahoma, Geneva, Verdana, Consolas,
and Menlo, while preserving the existing font-family order and fallback values.

In `@Justfile`:
- Around line 116-120: Update the html-js-iife and html-js-umd recipes to target
the existing example-apps/audio-js workspace package, while passing the
corresponding variant-specific script (such as star: iife or star: umd) through
the script argument. Remove the nonexistent html-js-iife and html-js-umd package
selectors.

In `@packages/js/src/wasmModule.js`:
- Around line 72-79: Update the catch block surrounding destroyWebGPU in the
WebGPU cleanup flow to report a cleanup or destruction failure, including the
caught error details. Remove the initialization wording and unrelated CPU
fallback message while preserving the existing error logging behavior.

In `@packages/js/vite.config.js`:
- Around line 9-47: Update the standalone entry in TARGETS to set needsCommonjs
to true, ensuring the existing `@rollup/plugin-commonjs` configuration recognizes
the CJS-shaped factory exported by build-wasm/standalone/img2num.js. Do not add
this setting to node-esm or node-cjs.

Learning: In Docusaurus projects, Markdown files (*.md, *.mdx) may contain anchor tags with onClick={(e) => { e.preventDefault(); window.location.href = '...'; }} to force a full page navigation, bypassing React SPA routing for static/external paths. Treat this as intentional and do not flag it as redundant in docs contexts. Apply this guidance broadly to Markdown docs across the repository (not just the single file) and focus reviews on more impactful patterns such as accessibility, SEO, and navigation consistency.

Verify the IIFE global-name contract.

The loader reads Img2Num. If the Vite IIFE library name differs, this example throws ReferenceError before initialization. Confirm that packages/js/vite.config.js sets the IIFE global name to Img2Num, then keep the loader and generated artifact aligned.

Pin the static-server executable.

These commands run npx --yes serve, but this package does not declare serve. npm can fetch a missing executable package into its cache and run it.

Wrap the CommonJS await in an async function.

The Node CJS documentation snippet uses await at module scope, which is invalid in CommonJS. The executable console-js-cjs/index.cjs wraps the imageToSvg call inside async function main().

Proposed fix
 const { imageToSvg } = require("img2num");
 const sharp = require("sharp");

+async function main() {
 // ... decode, then:
 const { svg } = await imageToSvg({ pixels, width, height });
+}
+
+main().catch((error) => {
+  console.error(error);
+  process.exitCode = 1;
+});

Preserve the Node.js Buffer bounds.

new Uint8ClampedArray(data.buffer) ignores data.byteOffset and data.byteLength. For any Buffer view, the pixel array can span the entire backing buffer or start at the wrong offset. Use the same bounded construction as example-apps/console-js-cjs/index.cjs.

Timestamp: 2026-04-02T18:39:20.647Z
Learning: In Ryan-Millard/Img2Num, `add_edge_pixel()` on a `Node` is intentionally designed to allow dual ownership of boundary pixels (the same pixel may appear in the node’s `m_pixels` and also in a neighboring node’s `m_edge_pixels` at the same time). This is required to avoid the SVG “1 pixel boundary problem” (a 1-pixel boundary gap artifact). Treat this as correct behavior: do not review it as a bug, memory/logic misuse, or an invalid data-structure invariant. Note that edge pixels are used only to expand the contour/binary representation for boundary tracing and do not affect node properties such as color.

Timestamp: 2026-04-11T22:21:32.583Z
Learning: In this repo’s development Docker image (Dockerfile.dev), keep the root user as an intentional, acceptable design for dev workflows. Rationale to preserve: pnpm is installed under /root/.local/share/pnpm, /usr/src/app is a host-mounted volume where UID mismatches can cause permission issues, and dev tooling needs root-level flexibility. Do not suggest switching to a non-root USER for Dockerfile.dev unless you can provide a careful, qualified alternative that avoids pnpm path and host-volume permission problems.

Learning: In Ryan-Millard/Img2Num, treat `docusaurus/faster` as a required runtime dependency: ensure it is present in `docs/package.json`. This is needed for Docusaurus 3.10 builds because the project’s `docs/docusaurus.config.js` uses `future: { v4: true }`, enabling `fasterByDefault`, which requires `docusaurus/faster` to be installed; it should not be removed or considered optional for performance in this repo.

docs/static/example-apps/umd/lib/require.js (1)

1-10: 📐 Maintainability & Code Quality

No change needed for lint/format exclusion.

docs/static/example-apps/umd/lib/require.js has no remaining concern: ESLint ignores docs/static/example-apps/, Prettier ignores docs/static/*, and the version is pinned at 2.3.8.

docs/static/example-apps/esm/index.html (1)

188-188: 🩺 Stability & Availability

No change needed. The ESM example imports ./lib/img2num.js, and lib/ contains both img2num.js and img2num.wasm, so the WASM glue resolves from the expected bundle directory.

Justfile (2)

31-31: Verify the workspace filter matches the manifest.

The help text identifies example-apps/html-js/package.json, but the recipe filters html-js-iife. Confirm that the manifest declares "name": "html-js-iife" and that the workspace includes this package. Otherwise, just html-js <script> fails before running the requested script.

#!/bin/bash
set -euo pipefail

python - <<'PY'
import json
from pathlib import Path

manifest = json.loads(Path("example-apps/html-js/package.json").read_text())
name = manifest.get("name")
print(f"manifest name: {name}")
if name != "html-js-iife":
    raise SystemExit("html-js-iife is not the manifest package name")

39-39: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Fix the API-reference ignore path.

docs/.gitignore is relative to the docs directory. Therefore, /docs/py/api-reference/ targets docs/docs/py/api-reference/, not docs/py/api-reference/. The new pydoc-markdown step in docs/scripts/prebuild.mjs Line 25 can leave generated files unignored.

Use /py/api-reference/ instead.

File: docs/docs/reference/react/components/ThemeSwitch/tests.md:123-124
Timestamp: 2026-01-04T15:34:04.654Z
Learning: In Docusaurus documentation, relative directory links (e.g., ../ or ../../../hooks/useTheme) resolve to index.md within the target directory. Do not require or force linking to index.md explicitly; such relative links remain valid and should not be changed when reviewing docs under the docs directory.

File: docs/docs/internal/core/api-reference.md:13-13
Timestamp: 2026-02-22T15:20:15.304Z
Learning: In Docusaurus projects, Markdown files (*.md, *.mdx) may contain anchor tags with onClick={(e) => { e.preventDefault(); window.location.href = '...'; }} to force a full page navigation, bypassing React SPA routing for static/external paths. Treat this as intentional and do not flag it as redundant in docs contexts. Apply this guidance broadly to Markdown docs across the repository (not just the single file) and focus reviews on more impactful patterns such as accessibility, SEO, and navigation consistency.
