Whenever you need to improve UI responsiveness or want to receive updates on your backend as they appear - you may use websocket subscriptions.
const accountSubscription = await TonClient.default.net.subscribe_collection({
collection: "accounts",
filter: { id: { eq: address } },
result: "balance",
}, (params, responseType) => {
if (responseType === ResponseType.Custom) {
console.log("Account has updated. Current balance is ", parseInt(params.result.balance));
}
});
const messageSubscription = await TonClient.default.net.subscribe_collection({
collection: "messages",
filter: {
src: { eq: address },
OR: {
dst: { eq: address },
}
},
result: "boc",
}, async (params, responseType) => {
try {
if (responseType === ResponseType.Custom) {
const decoded = (await TonClient.default.abi.decode_message({
abi: abiContract(your-contract-abi),
message: params.result.boc,
}));
switch (decoded.body_type) {
case MessageBodyType.Input:
console.log(`External inbound message, function "${decoded.name}", parameters: `, JSON.stringify(decoded.value));
break;
case MessageBodyType.Output:
console.log(`External outbound message, function "${decoded.name}", result`, JSON.stringify(decoded.value));
break;
case MessageBodyType.Event:
console.log(`External outbound message, event "${decoded.name}", parameters`, JSON.stringify(decoded.value));
break;
}
}
} catch (err) {
console.log('>>>', err);
}
});
