## Use as build checker

```ts

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: ['*'],

      },

    }),

  ],

});
