Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch astro-icon@0.8.1 for the project I'm working on.

Here is the diff that solved my problem:

diff --git a/node_modules/astro-icon/lib/createIconPack.ts b/node_modules/astro-icon/lib/createIconPack.ts
index c49ccae..3045d92 100644

+      const baseUrl = new URL(pathToFileURL(resolvePackage(pkg) ?? '') + "/");
       const path = fileURLToPath(
         new URL(dir ? `${dir}/${name}.svg` : `${name}.svg`, baseUrl)
       );

This issue body was partially generated by patch-package.
