I have chat message system.
I have code:
<template>
<li :class="className">
{{ message }}
</li>
</template>
<script>
export default {
props: [
'message',
'user',
'time',
'seen',
],
computed: {
className() {
return this.seen;
}
},
mounted() {
console.log('Component mounted.')
}
}
</script>
App.js:
data:{ message: '', convId: 1, chat: { message: [], user: [], time: [], seen: [], }, typing: '', }, .... watch: { message() { Echo.private('chat') .whisper('typing', { name: this.message }); } }, methods: { send(){ if(this.message.length != 0 && this.message.length <= 4000) { this.chat.message.push(this.message); this.chat.user.push('you'); this.chat.time.push(this.getTime()); this.chat.seen.push('unread'). //set class unread message for user axios.post('/sendMessage', { message: this.message, //lastName: 'Flintstone' }) .then(response => { console.log(response); this.message = ''; }) .catch(error => { console.log(error); }); } }, seenMessage() { axios.post('/setMessagesSeen/' + this.convId) //this request mark messages in chat all readed for auhenticated user .then( response => { this.chat.seen.push(''); //remove unread class }) .catch( response => { console.log(response) } ) }, getTime() { let time = new Date(); return time.getHours() + ':' + time.getMinutes(); } }, mounted() { Echo.private('chat') .listen('ChatEvent', (e) => { this.chat.message.push(e.message); this.chat.user.push(e.user); this.chat.time.push(this.getTime()); this.chat.seen.push('unread'). //set class unread message for user console.log(e); }) .listenForWhisper('typing', (e) => { if(e.name != '') this.typing = 'typing..'; else this.typing = null; }); }
My chat.blade.php:
<message v-for="value,index in chat.message"
:key=value.index
:user=chat.user[index]
:message="chat.message[index]"
:time="chat.time[index]"
:seen="chat.seen[index]"
>
</message>
<div class="form-group">
<textarea maxlength="4000" cols="80" rows="3" class="message-input form-control" v-model='message' v-on:click="seenMessage"></textarea>
</div>
<div class="form-group">
<button type="button" class="btn btn-lg btn-primary" v-on:click="send">Send message</button>
</div>
My function seen:
public function setMessagesSeen(Conversation $conversation) {
$user = User::find(Auth::id());
$conversations = Chat::conversation($conversation->id);
//$dd = Chat::conversations($conversation)->for($user)->readAll();
dd(Chat::conversations($conversations)->for($user)->getMessages()->where('body', 'asdfsadfsd'));
//$message = Chat::messages($message)->for($user)->markRead();
broadcast(new HasSeenMessage($message));
return response('ok');
}
How I can send class "unread" to element div other user? I can paste class on current user, and I get color on element chat only for me, but how I can hide element for me and other user, when message is seen?
I want do read/unread function for users. Example:
If user in real time send message I send class unread, when other user click on textarea, I remove class unread, and said user, that message is seen. How I can do it in real time add/remove class unread? My function is not working.
To do this you have to create an Event in your Laravel application that you will broadcast on a precise channel (you can for example give the name 'chat. {Conversation}. {User_id}') and with Laravel Echo you will listen this event!
I allowed myself to make some changes in your code -:)
I presume you have this class HasSeenEvent
<?php
namespace App\Events;
use App\Order;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
class HasSeenEvent implements ShouldBroadcast
{
use SerializesModels;
public $message;
/**
* Create a new event instance.
*
* @param Message $message
* @return void
*/
public function __construct(Message $message)
{
$this->message = $message;
}
public function broadcastOn()
{
// I presume we can get conversation id like this : $this->message->conversation->id
return new PrivateChannel('chat.'.$this->message->conversation->id.'.'.$this->message->sender->id);
}
}
Then, in your routes/broadcast.php declare this route chat.{conversation}.{user_id}
In the function where you put the 'seen' to 1 you broadcast the event at the same time
broadcast(new HasSeenMessage($message))
Then you listen to this event in your vuejs code
components/Message.js
<template>
<li :class="className">
{{ message }}
</li>
</template>
<script>
export default {
props: [
'message',
'user',
'time',
'readed',
],
computed: {
className() {
return this.readed == 1 ? 'seen' : 'unread';
}
},
mounted() {
console.log('Component mounted.')
}
}
</script>

if (this.message.length != 0 && this.message.length <= 4000) {
let data = {

}
},
seenMessage() {
axios.post('/setMessagesSeen/' + this.convId) //this request mark messages in chat all readed for auhenticated user
.then(response => {
//This is not the best way to do that
this.chat.messages[this.messages.length -1 ].readed = 0
}).catch(response => {
console.log(response)
})
},
getTime() {
let time = new Date();
return time.getHours() + ':' + time.getMinutes();
}
},
mounted() {
Echo.private('chat')
.listen('ChatEvent', (e) => {
this.chat.messages.push({
content: e.message,
user: e.user,
time: this.getTime(),
readed: 0
})
console.log(e);
})
.listenForWhisper('typing', (e) => {
if (e.name != '')
this.typing = 'typing..';
else
this.typing = null;
});
// I presume to can access to user info
let that = this
Echo.private('chat.'+convId+'.'+user.id)
.listen('HasSeenMessage', (e) => {
let message = e.message
let lookingForMessage = that.chat.messages.find((m) => {
// I presume in your db messages table has field content and time
return m.content == message.content && m.time => message.time
})
try {
lookingForMessage.readed = 1
}catch (err){
// message not found
console.log(err)
}
})
}
