This commit adds some syntactic sugar around acknowledgements:
- `emitWithAck()`
```js
try {
const responses = await io.timeout(1000).emitWithAck("some-event");
console.log(responses); // one response per client
} catch (e) {
// some clients did not acknowledge the event in the given delay
}
io.on("connection", async (socket) => {
// without timeout
const response = await socket.emitWithAck("hello", "world");
// with a specific timeout
try {
const response = await socket.timeout(1000).emitWithAck("hello", "world");
} catch (err) {
// the client did not acknowledge the event in the given delay
}
});
```
- `serverSideEmitWithAck()`
```js
try {
const responses = await io.timeout(1000).serverSideEmitWithAck("some-event");
console.log(responses); // one response per server (except itself)
} catch (e) {
// some servers did not acknowledge the event in the given delay
}
```
