Error: Failed to resolve module specifier "@ton/ton"

[ronaldoguedess]

It's working fine locally using npm run dev, but it fails when I deploy to Vercel or send it to a web server.

Vercel URL:
https://ton-swap-chi.vercel.app/

Error:

My code:

import { Buffer } from 'buffer';
window.Buffer = Buffer;

// Importando as bibliotecas necessárias
import { TonClient, toNano } from "@ton/ton"; 
import { DEX, pTON } from "@ston-fi/sdk";

// Verificando o conteúdo de DEX
console.log("DEX:", DEX);

(async () => {
    try {
        // Inicializando o cliente
        const client = new TonClient({
            endpoint: "https://testnet.toncenter.com/api/v2/jsonRPC",
        });

        // Inicializando o router usando a versão v1
        const router = client.open(
            DEX.v2_1.Router.create(
                "kQALh-JBBIKK7gr0o4AVf9JZnEsFndqO0qTCyT-D-yBsWk0v" // CPI Router v1
            )
        );

        // Inicializando o proxy para pTON usando a versão v1
        const proxyTon = pTON.v2_1.create(
            "kQACS30DNoUQ7NfApPvzh7eBmSZ9L4ygJ-lkNWtba8TQT-Px" // pTON v1
        );

        // Definindo os parâmetros da transação de swap
        const userWalletAddress = "UQBry_ewauy7EZ8UzqQwAkQY4T402qNlvyUYyldsE4XhY-xy"; 
        const txParams = await router.getSwapTonToJettonTxParams({
            userWalletAddress: userWalletAddress,
            proxyTon: proxyTon,
            offerAmount: toNano("1"), // 1 TON
            askJettonAddress: "kQDLvsZol3juZyOAVG8tWsJntOxeEZWEaWCbbSjYakQpuYN5", // TestRED
            minAskAmount: "1", // Não menos que 1 nano TestRED
            queryId: 12345,
        });

        console.log("Transaction Parameters:", txParams);


        // Send tx
        //const result = await client.net.sendTransaction(txParams);
        //console.log("Transaction Result:", result);
        // console.log("Transaction Result:", result);


    } catch (error) {
        console.error("Erro:", error);
    }
})();

This does not look like an SDK issue. More like build specific issue

Did you install the ton package according to their installation guide?

Besides that, my only other recommendation will be to check the way you build the app
