Fix extra swc optimizer applied to node_modules in browser layer #62051

huozhi · 2024-02-14T13:25:16Z

What

Disable swc transform optimizer for node_modules in browser layer of app router bundles

Fixes #61858
Fixes #60644
Fixes #60920
Fixes #61740
Closes NEXT-2418

Why

In browser there could be not only one runtime, it could have both js worker and browser. In js worker the typeof window is not as same as in browser, so disabling the swc optimizer which will replace the code. Leave the condition as it as.
