``ts import { transform } from 'oxc-import-transformer'; import { readFileSync } from 'node:fs';

const file = '/path/to/file.ts'; const content = readFileSync(file, 'utf-8');

const code = await transform({ filename: file, content, sourcemap: false, libraryTransform: [ { libraryName: '@ray-js/smart-ui', format: (localName: string, importedName: string) => { returnimport ${localName} from '@ray-js/smart-ui/lib/${importedName}';; }, }, { libraryName: '@ray-js/ui-smart', format: (localName: string, importedName: string) => { returnimport ${localName} from '@ray-js/ui-smart/lib/${importedName}';; }, }, ], });`
