Expected behavior

When building an app with optional dependencies and the Vite plugin, optional dependencies are included in the build output.

Actual behavior

Optional dependencies are excluded from the output.

Steps to reproduce

Build a project using https://github.com/lovell/sharp, which has optional dependencies. They will not be in the packaged node_modules, and so their native binaries can not be copied.

Additional information

Adding them as dependencies is a poor solution, since they are platform-specific.

I have had to fix this by using this hook in my Forge config:

async packageAfterCopy(_config, buildPath) {
  await NodeFSExtra.copy(
    "node_modules/@img",
    NodePath.join(buildPath, "node_modules/@img"),
  );
},
