Hi everyone !!!
First of all “sorry Yisrael…will not try to do like that from now on…” 
So, In my previous post I was answered by Yisrael how to use RealTime Api after afterInsert Hook…
Why I created this post was to know if I can use the above function in the onInput event function…
Very Thanks !!!
PARDON ME YISRAEL !!!
No problem !!!
I have found the code →
1st create a .jsw backend file called realtime.jsw →
//realtime.jsw
import { publish } from 'wix-realtime-backend';
export function publishMessage(userId) {
const channel = { name: 'type' };
const payload = {userId};
return publish(channel, payload);
}
In the page →
import { publishMessage } from 'backend/realtime';
import * as realtime from 'wix-realtime';
export function input1_input(event) { //when the user types something in the input
return publishMessage()
}
async function type({ payload }) {
if ($w('#notificationBox2').hidden) {
$w('#notificationText2').text = JSON.stringify(fullName) + " has posted";
$w('#notificationBox2').show('fade');
setTimeout(() => $w('#notificationBox2').hide('fade'), 3000);
} else {
setTimeout(() => type({ payload }), 1000);
}
}
For reference
Thanks Yisrael !!!
