webpack 5.112.0 (published 2026-10-15, now latest) moved lib/dependencies/WorkerDependency to lib/dependencies/worker/WorkerDependency. The worker loader requires the old path, so every new webpack-based project (ns create installs webpack ^5) fails at ns run with "Cannot find module 'webpack/lib/dependencies/WorkerDependency'", and the app dies at launch.

5.112 also moved lib/RuntimeGlobals to lib/runtime/RuntimeGlobals.

The loader now requires WorkerDependency at the new path, falling back to the old one, and takes RuntimeGlobals from webpack's public export (present in both). WorkerDependency.Template.prototype.apply, which the loader patches, is unchanged in 5.112.

Verified with webpack 5.112.0 on a fresh ns create app: ns run ios syncs and runs, and a worker round trip works (the bundle carries the loader's patch).

Until this ships, the workaround is npm install -D [email protected].
