Introduction

In this tutorial, we will learn how to Create a simple chat application using GPT and .NET 7.2. We will start by creating a web API using .NET framework and then Consume it using an HTML, CSS, and JavaScript client. The chat functionality will be powered by GPT, and we will be able to save and load chat history. So, let's dive straight into the hands-on session!

Creating a Web API using .NET 7.2

To begin with, we will open Visual Studio and create a new web API project using .NET 7.2. We will name the project "Chatbot API" and let .NET generate a default project for us. The project will have an API controller called "WeatherForecastController" which returns weather forecast data when requested. We will run the web API to verify that it is working correctly.

Consuming the Web API with HTML, CSS, and JavaScript

Next, we will create a client application in HTML, CSS, and JavaScript to consume the web API. We will create a simple page with a dropdown for sender and receiver names, a text box to send messages, and a button to send the message. When the button is clicked, the message will be sent, and the text box will be reset. Additionally, we will implement the functionality to load chat history and enhance the user interface with HTML, CSS, and JavaScript. We will run the client application on an HTTP server to ensure it can call the web API.

Creating a Model Class for Chat Messages

Before proceeding further, we will create a model class called "ChatMessage" to store the details of each chat message. The model class will include properties for the message ID, sender name, receiver name, message content, and timestamp. We will use this model class to save and retrieve chat history.

Implementing Action Methods to Save and Load Chat History

In this step, we will modify the web API controller to include action methods for saving and loading chat history. We will add an action method to save a chat message to the chat history, incrementing the message ID and setting the timestamp to the Current time. Additionally, we will add an action method to retrieve the chat history, which will return a list of chat messages. We will test these action methods to ensure they are functioning correctly.

Enhancing the User Interface with HTML, CSS, and JavaScript

To create a beautiful user interface for our chat application, we will enhance the HTML, CSS, and JavaScript code in our client application. We will modify the layout, styles, and functionality to provide a seamless and engaging user experience. We will also ensure that the chat messages are displayed in a readable format with appropriate spacing and formatting.

Enabling Cross-Origin Resource Sharing (CORS)

To resolve any cross-origin issues between the web API and client application, we will enable Cross-Origin Resource Sharing (CORS). We will add the required code in the startup class of the web API project to allow requests from different origins. This will ensure that the client application can successfully call the web API without any restriction.

Troubleshooting and Debugging

In this step, we will address common issues, troubleshoot any errors, and debug our chat application. We will use debugging techniques to identify and resolve any issues with the web API or the client application. We will log any Relevant information and make necessary adjustments to ensure smooth functionality.

Finalizing the Chat Application

Once all the components are working smoothly, we will finalize our chat application. We will conduct thorough testing to ensure that messages are sent and received correctly, chat history is saved and loaded accurately, and the user interface is visually appealing and functional. We will make any necessary refinements Based on user feedback and ensure that the application is ready for deployment.

Conclusion

In conclusion, we have successfully created a chat application using GPT and .NET 7.2. We have learned how to create a web API and consume it with an HTML, CSS, and JavaScript client. We have implemented functionality to save and load chat history, enhanced the user interface, and resolved any cross-origin issues. Our chat application is now ready to be used for real-time communication and collaboration. Enjoy using and customizing this application to meet your specific needs!
