Hivyo, hivi karibuni nilikuwa na mradi ambapo nilihitaji kipengele cha mazungumzo. mawazo yangu ya kwanza yalikuwa kama tu kuunganisha chombo cha sasa kama Jivo au LiveChat, lakini sikutaka kutegemea bidhaa za tatu kwa kitu ambacho kinaweza kujengwa moja kwa moja kwenye jopo langu la usimamizi. Katika chapisho hili, nitakuja kupitia jinsi nilivyojenga: usanifu, mazingira ya sockets na hali, na vipengele vya UI ambavyo vimeunganisha yote. Kwa nini ? Admirali wa Admirali wa imeundwa ili iwe inapatikana. Pamoja na njia ya msingi ya faili, hooks, na vipengele vinavyoweza kukuzuia, haina kufungwa - inakuwezesha kutekeleza vipengele vya kibinafsi. Hiyo ndiyo niliyohitaji kwa ajili ya mazungumzo: sio tu CRUD, lakini ujumbe wa wakati halisi ambao bado unaingiliwa kwa usahihi kwenye panel. Admirali wa Mipango ya Chat Hapa ni jinsi ya kuandaa mambo: Core components 
 
 
 
 
 
 ChatPage - ukurasa mkuu wa chat ChatSidebar – orodha ya mazungumzo na maoni ya awali ChatPanel – hufanya mazungumzo yaliyochaguliwa MessageFeed - Mstari wa ujumbe MessageInput – kuingia na faili ya upload Context providers 
 
 
 SocketContext - kusimamia uhusiano wa WebSocket ChatContext - kusimamia mazungumzo na hali ya ujumbe Ukurasa Mkuu wa Chat Pamoja na njia ya Admiral, kuanzisha ukurasa mpya ulikuwa rahisi. // pages/chat/index.tsx

import ChatPage from '@/src/crud/chat'
export default ChatPage
 Hii ilikuwa ya kutosha kufanya ukurasa huu inapatikana katika . /chat Utekelezaji wa msingi ulikuwa : src/crud/chat/index.tsx // src/crud/chat/index.tsx

import React from 'react'

import { Card } from '@devfamily/admiral'
import { usePermissions, usePermissionsRedirect } from '@devfamily/admiral'
import { SocketProvider } from './contexts/SocketContext'
import { ChatProvider } from './contexts/ChatContext'
import ChatSidebar from './components/ChatSidebar'
import ChatPanel from './components/ChatPanel'
import styles from './Chat.module.css'

export default function ChatPage() {
  const { permissions, loaded, isAdmin } = usePermissions()
  const identityPermissions = permissions?.chat?.chat
  
  usePermissionsRedirect({ identityPermissions, isAdmin, loaded })

  return (
    <SocketProvider>
      <ChatProvider>
        <Card className={styles.page}>
          <PageTitle title="Corporate chat" />
          <div className={styles.chat}>
            <ChatSidebar />
            <ChatPanel />
          </div>
        </Card>
      </ChatProvider>
    </SocketProvider>
  )
}
 Hapa, nilifungua ukurasa wa na ya , na kutumia hooks ya Admiral kwa ruhusa na redirect. SocketProvider ChatProvider Utawala wa Uunganisho wa WebSocket na SocketContext Kwa ajili ya mazungumzo ya wakati halisi, nilichagua Centrifuge. nilitaka mantiki yote ya uhusiano katika sehemu moja, hivyo niliunda : SocketContext // src/crud/chat/SocketContext.tsx

import React from 'react'

import { Centrifuge } from 'centrifuge'
import { createContext, ReactNode, useContext, useEffect, useRef, useState } from 'react'
import { useGetIdentity } from '@devfamily/admiral'

const SocketContext = createContext(null)

export const SocketProvider = ({ children }: { children: ReactNode }) => {
    const { identity: user } = useGetIdentity()
    const [lastMessage, setLastMessage] = useState(null)
    const centrifugeRef = useRef(null)
    const subscribedRef = useRef(false)

    useEffect(() => {
        if (!user?.ws_token) return

        const WS_URL = import.meta.env.VITE_WS_URL
        if (!WS_URL) {
            console.error('❌ Missing VITE_WS_URL in env')
            return
        }

        const centrifuge = new Centrifuge(WS_URL, {
            token: user.ws_token, // Initializing the WebSocket connection with a token
        })
        
        centrifugeRef.current = centrifuge
        centrifugeRef.current.connect()

        // Subscribing to the chat channel
        const sub = centrifugeRef.current.newSubscription(`admin_chat`)

        sub.on('publication', function (ctx: any) {
		       setLastMessage(ctx.data);
        }).subscribe()

        // Cleaning up on component unmount
        return () => {
            subscribedRef.current = false
            centrifuge.disconnect()
        }
    }, [user?.ws_token])

    return (
        <SocketContext.Provider value={{ lastMessage, centrifuge: centrifugeRef.current }}>
            {children}
        </SocketContext.Provider>
    )
}

export const useSocket = () => {
    const ctx = useContext(SocketContext)
    if (!ctx) throw new Error('useSocket must be used within SocketProvider')
    return ctx
}
 Mtazamo huu ulihusisha kuanzisha uhusiano, usajili, na kusafisha. sehemu zingine za programu zilizotumika tu . useSocket() Kuendesha hali ya chat na ChatContext Kisha, nilihitaji kukusanya mazungumzo, kupakia ujumbe, kutuma ujumbe mpya, na kujibu updates ya WebSocket. : ChatContext // src/crud/chat/ChatContext.tsx

import React, { useRef } from "react";

import {
  createContext,
  useContext,
  useEffect,
  useState,
  useRef,
  useCallback,
} from "react";
import { useSocket } from "./SocketContext";
import { useUrlState } from "@devfamily/admiral";
import api from "../api";

const ChatContext = createContext(null);

export const ChatProvider = ({ children }) => {
  const { lastMessage } = useSocket();
  const [dialogs, setDialogs] = useState([]);
  const [messages, setMessages] = useState([]);
  const [selectedDialog, setSelectedDialog] = useState(null);
  const [urlState] = useUrlState();
  const { client_id } = urlState;

  const fetchDialogs = useCallback(async () => {
    const res = await api.dialogs();
    setDialogs(res.data || []);
  }, []);

  const fetchMessages = useCallback(async (id) => {
    const res = await api.messages(id);
    setMessages(res.data || []);
  }, []);

  useEffect(() => {
    fetchMessages(client_id);
  }, [fetchMessages, client_id]);

  useEffect(() => {
    fetchDialogs();
  }, [fetchDialogs]);

  useEffect(() => {
    if (!lastMessage) return;

    fetchDialogs();

    setMessages((prev) => [...prev, lastMessage.data]);
  }, [lastMessage]);

  const sendMessage = useCallback(
    async (value, onSuccess, onError) => {
      try {
        const res = await api.send(value);
        if (res?.data) setMessages((prev) => [...prev, res.data]);
        fetchDialogs();
        onSuccess();
      } catch (err) {
        onError(err);
      }
    },
    [messages]
  );
  
  // Within this context, you can extend the logic to:
  // – Mark messages as read (api.read())
  // – Group messages by date, and more.

  return (
    <ChatContext.Provider
      value={{
        dialogs,
        messages: groupMessagesByDate(messages),
        selectedDialog,
        setSelectedDialog,
        sendMessage,
      }}
    >
      {children}
    </ChatContext.Provider>
  );
};

export const useChat = () => {
  const ctx = useContext(ChatContext);
  if (!ctx) throw new Error("useChat must be used within ChatProvider");
  return ctx;
};
 Hii ilifanya kila kitu - kukusanya, kuhifadhi, kuboresha - katika sehemu moja. Mfano wa API Client Niliongeza mteja mdogo wa API kwa maombi: // src/crud/chat/api.ts

import _ from '../../config/request'
import { apiUrl } from '@/src/config/api'

const api = {
    dialogs: () => _.get(`${apiUrl}/chat/dialogs`)(),
    messages: (id) => _.get(`${apiUrl}/chat/messages/${id}`)(),
    send: (data) => _.postFD(`${apiUrl}/chat/send`)({ data }),
    read: (data) => _.post(`${apiUrl}/chat/read`)({ data }),
}

export default api
 Viungo vya UI: Sidebar + Panel + Input Baada ya hapo nilikwenda kwenye uwanja wa ndege. Mchezo wa // src/crud/chat/components/ChatSidebar.tsx

 Stili ya Nilijenga kwa kutumia mabadiliko ya CSS ya Admiral ili kudumisha kila kitu kwa utaratibu: .chat {
  border-radius: var(--radius-m);
  border: 2px solid var(--color-bg-border);
  background-color: var(--color-bg-default);
}

.message {
  padding: var(--space-m);
  border-radius: var(--radius-s);
  background-color: var(--color-bg-default);
}
 Kuongeza Maelezo Pia niliongeza taarifa kwa ujumbe mpya wakati mtumiaji hakuwa akiangalia mazungumzo hayo: import { useNotifications } from '@devfamily/admiral'

const ChatContext = () => {
  const { showNotification } = useNotifications()
  
  useEffect(() => {
    if (!lastMessage) return
    
    if (selectedDialog?.client_id !== lastMessage.client_id) {
      showNotification({
        title: 'New message',
        message: `${lastMessage.client_name}: ${lastMessage.text || 'Image'}`,
        type: 'info',
        duration: 5000
      })
    }
  }, [lastMessage, selectedDialog, showNotification])
}
 Mwisho wa Na tu kama hiyo, badala ya kutumia zana za tatu, niliunda moja kwa moja kwenye paneli yangu ya usimamizi inayotokana na Admiral. njia ya Admiral, mazingira, hooks, na mfumo wa kubuni ilifanya inawezekana kujenga mazungumzo ya wakati halisi ambayo ilihisi ya asili kwa paneli. Matokeo yalikuwa mazungumzo kamili ya kibinafsi: ujumbe wa wakati halisi, mazungumzo, uhariri wa faili, na taarifa - yote iliyounganishwa na chini ya udhibiti wangu. Angalia, na ujue kile unachokiona!
