How can I use customName as a function in transformImport?

[khangviet1996]

After migrating my large CRA project to rsbuild, I noticed significant reductions in both build time and development time. However, there's a project issue I’d like to resolve.

In my project, We're using a barrel file to import common components, as shown here:

import { Form, FormAddButton } from 'common/components';

I want to convert it to individual imports, like:

import FormAddButton from 'common/components/button/FormAddButton';

I tried using this configuration to achieve that:

{
  libraryName: 'common/components',
  customName: 'common/components/button/{{ member }}',
  transformToDefaultImport: true,
}

Is there a way to make customName function-based? That would make it much more flexible! Like this!

      {
        libraryName: 'common/components',
        customName: (name) => {
          // Assume certain components are in 'form', 'button', and 'notifications'
          if (name === 'Form') return `common/components/form/Form`;
          if (name === 'FormAddButton') return `common/components/button/FormAddButton`;
          if (name === 'CustomNotification') return `common/components/notifications/CustomNotification`;
          return `common/components/others/${name}`;
        },
        transformToDefaultImport: true,
      },

Thank you!

For performance reasons, Rspack does not support customName function, see #3696

Thank you so much, I have to refactor it :D
