Interactive Chat in PromptSpark With SignalR

Building a Real-Time AI-Driven Chat Application

In this guide, we will explore how to implement a real-time, AI-driven chat application using PromptSpark. By leveraging ASP.NET SignalR and OpenAI's GPT via Semantic Kernel, you can create a dynamic and interactive chat experience.

What is PromptSpark?

PromptSpark is a versatile platform that allows developers to create interactive applications with ease. It provides a robust environment for integrating various technologies to enhance user interaction.

Why Use SignalR?

SignalR is an ASP.NET library that enables real-time web functionality. It allows server-side code to push content to connected clients instantly, making it ideal for chat applications where real-time communication is crucial.

Leveraging Semantic Kernel and OpenAI GPT

Semantic Kernel is a framework that facilitates the integration of AI models like OpenAI's GPT into applications. By using Semantic Kernel, developers can harness the power of AI to provide intelligent responses and enhance user interaction in chat applications.

Step-by-Step Implementation

1. Setting Up Your Environment

• Install ASP.NET Core: Ensure you have the latest version of ASP.NET Core installed.
• Create a New Project: Use Visual Studio or your preferred IDE to create a new ASP.NET Core project.

2. Integrating SignalR

• Add SignalR to Your Project: Use NuGet Package Manager to install the SignalR library.
• Configure SignalR: Set up SignalR in your

  Startup.cs

  file to enable real-time communication.

public void ConfigureServices(IServiceCollection services)
{
    services.AddSignalR();
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseSignalR(routes =>
    {
        routes.MapHub<ChatHub>("/chatHub");
    });
}

3. Implementing the Chat Hub

• Create a Chat Hub: Implement a SignalR hub to handle chat messages.

public class ChatHub : Hub
{
    public async Task SendMessage(string user, string message)
    {
        await Clients.All.SendAsync("ReceiveMessage", user, message);
    }
}

4. Integrating Semantic Kernel and OpenAI GPT

• Install Semantic Kernel: Add the Semantic Kernel package to your project.
• Configure AI Model: Set up the OpenAI GPT model within Semantic Kernel to process chat inputs and generate responses.

5. Building the Frontend

• Create a Chat Interface: Use HTML and JavaScript to build a simple chat interface.
• Connect to SignalR: Use JavaScript to connect to the SignalR hub and handle incoming messages.

<script src="https://cdnjs.cloudflare.com/ajax/libs/microsoft-signalr/3.1.18/signalr.min.js"></script>
<script>
    const connection = new signalR.HubConnectionBuilder().withUrl("/chatHub").build();

    connection.on("ReceiveMessage", function (user, message) {
        // Display message in chat
    });

    connection.start().catch((err) => console.error(err.toString()));
</script>

Conclusion

By following these steps, you can build a robust, real-time chat application in PromptSpark using ASP.NET SignalR and OpenAI GPT via Semantic Kernel. This integration not only enhances user interaction but also leverages the power of AI to provide intelligent and context-aware responses.
