 The libraries Taquito and Beacon SDK are designed to run in a Node.js environment. However, we are running them in a browser. This causes some issues. For example, the Beacon SDK uses the Node.js `buffer`, `stream`, and `util` modules. These modules are not available in the browser. Fortunately, there are browser-compatible versions of these modules. We can use these versions instead of the Node.js versions. To do this, we need to install the following packages:
 
 ```bash
-npm i buffer stream-browserify util
+npm i -D vite-plugin-node-polyfills
 ```
 
-Now we need to tell Vite to use these packages instead of the Node.js versions. To do this, open the file `vite.config.ts` and add the following code:

 ### Running the dApp
 
 Make sure that the command `npm run dev` is still running in the terminal, and that there are no build errors.
