const config = {

};

Use as build checker

export default defineConfig({
  plugins: [
    UnpluginDetectDuplicatedDeps({
      // will exit build process if duplicated deps found
      throwErrorWhenDuplicated: true,
      // ignore specific duplicated deps
      ignore: {
        axios: ['0.27.2'],
        vue: ['*'],
      },
    }),
  ],
});
