    ...
]

Options

    },
    "module-with-specific-path: {
        "intern": { "path": "/lib/intern" }

    }
}

QA

Q1: I don t see any changes to my bundle size

OK, with version < 4.23 there are basic components which drain all components. Fix: https://github.com/Talend/ui/pull/2610 included in 4.23.0 version (f14d41ae4d13b54720994244a17b1bcc0acbaf62)

My App doesn't work once the plugin is activated

You may have a resolution to undefined in some corner case not already handled by the plugin.

The plugin first try to detect corner case. The last operation is a simple shift of import to /lib

So please give the corresponding corner case so we can do a fix.

Is there an alternative ?

Yes you can also use a codemode which is provided in https://github.com/Talend/ui/pull/2607 so your code base is updated using same technics and so you can do the fix yourself because it s your code.
