Pulse Chat

Pulse Chat is an enterprise-ready customer support platform designed for modern SaaS companies. It unifies customer communications across web chat, email, and knowledge base inquiries into a single fast, synchronized inbox.

Key Highlights

• AI Auto-Replies: Integrates Google Vertex AI and vector embeddings to answer recurring support questions instantly from documentation.
• WebSocket Clustering: Utilizes Redis pub/sub to distribute millions of live events across horizontal Node.js replicas without latency.
• Role-Based Workflows: Built granular permissions for admins, team leads, support agents, and end customers.

Architecture Snippet

import { Server } from "socket.io";
import { createAdapter } from "@socket.io/redis-adapter";
import { pubClient, subClient } from "./redis.config";

export function initializeRealtimeEngine(httpServer: any) {
  const io = new Server(httpServer, {
    cors: { origin: process.env.ALLOWED_ORIGINS?.split(",") },
    transports: ["websocket", "polling"],
  });

  io.adapter(createAdapter(pubClient, subClient));

  io.on("connection", (socket) => {
    socket.on("join:conversation", (conversationId) => {
      socket.join(`room:${conversationId}`);
    });

    socket.on("send:message", async (payload) => {
      io.to(`room:${payload.conversationId}`).emit("new:message", payload);
    });
  });

  return io;
}
