Buffer error, when I try to create an OPCUAClient in React+TypeScript in Vite-project

Node
1

I made an installation of node-opcua and buffer, but when i tried to run the code:

import { useEffect, useState } from ‘react’

import reactLogo from ‘./assets/react.svg’

import viteLogo from ‘/vite.svg’

import ‘./App.css’

import { OPCUAClient } from “node-opcua”;

import { Buffer } from “buffer”;

const PLC_ADDRESS = “opc.tcp://172.16.90.1:4840”; // OPC UA endpoint URL

const nodeIdInt = ‘ns=3;s=“DB1”.int’; // Node ID for the value to read

const nodeIdBool = ‘ns=3;s=“DB1”.int’; // Node ID for the value to read

const client = new OPCUAClient();
…

i got always error about buffer, refering to line code:
const client = new OPCUAClient();

The console returns the errors:

client.ts:112 ReferenceError: Buffer is not defined
