Request: Update icon-gen to support sharp@0.34 (libvips conflicts with modern sharp versions)

[taohel]

Hello maintainers,

First of all, thank you for providing icon-gen, which is still one of the simplest tools to generate .ico and .icns assets for Electron apps.

However, the project currently depends on an outdated version of sharp, which causes serious compatibility issues when used in modern Node.js environments.

🚨 The Problem

When a project installs both:

sharp@0.34+ (modern, using the new @img/sharp-* distributions)

icon-gen (bundled with its own older sharp version)

Node loads two different versions of libvips, resulting in warnings and unpredictable behavior such as:

modules/@img/sharp-libvips-darwin-arm64/lib/libvips-cpp.8.17.3.dylib and
node_modules/icon-gen/node_modules/@img/sharp-libvips-darwin-arm64/lib/libvips-cpp.42.dylib
One of the two will be used. Which one is undefined.

This is a direct result of mixing sharp versions with incompatible libvips binaries.

💡 Why this matters

Many modern Node.js / Electron projects already use sharp@0.33+ or sharp@0.34+ for image processing.
Having icon-gen bundle an older version of sharp makes both tools conflict and causes:

libvips loader warnings

unpredictable results

crashes in some environments

difficulty using icon-gen inside Electron build pipelines

🙏 Feature Request

Please update icon-gen to use (or allow using) sharp@0.34.x
or at least the currently maintained series.

Recommended improvements:

Update sharp to the newest version (0.34.x).

Or make sharp a peer dependency, so icon-gen uses the project's installed version.

Or remove sharp as a bundled nested dependency to avoid libvips duplication.

This update would resolve libvips conflicts and allow icon-gen to be used safely alongside modern toolchains.

✔ Environment Example

Node.js 20+

macOS ARM64

sharp@0.34.x

icon-gen installed from latest npm version

🙌 Thank you!

I believe updating sharp support would significantly improve icon-gen’s compatibility and make it usable again in modern Electron development.
