build: Not able to server render.

Hi I am trying to integrate `react-view` in `docusaurus`. While running the dev server `fs` not found issue was there. I fixed it by chain the webpack config.
```
 node: {
          fs: 'empty',
        },
```

Unfortunately while building the `prod`  build which is server rendered. I am getting `fs` error as it's been set to `empty`.
