Building a Chatbot with the ChatGPT API

In this tutorial, we will be building a chatbot using the new ChatGPT API. The chatbot will be able to answer questions Based on user input, making it a great introduction for anyone looking to integrate this API into their React applications. We will use the React framework and a library called @chatscope/chat-ui-kit-react to easily Create the chat interface.

1. Introduction

In this section, we will provide an overview of the project and the features of the ChatGPT API. We will also explain the benefits of using the GPT 3.5 turbo model, which is more affordable than previous versions, to add AI capabilities to React applications.

2. Setting up the Frontend

To start building our chatbot application, we need to set up the frontend. We will use the create-react-app command to create a new React application and install the necessary packages, including @chatscope/chat-ui-kit-react for building the chat interface.

3. Creating the Chat Interface

In this section, we will create the chat interface using the components provided by the @chatscope/chat-ui-kit-react library. We will import the necessary components, such as the main container, chat container, message list, message, message input, and typing indicator. These components will allow us to display messages, input text, and Show typing indicators.

4. Handling User Input

To enable users to input text and send messages in the chatbot interface, we need to handle user input. We will add an input field with a placeholder text and an onSend event that triggers a function called handleSend. Within the handleSend function, we will create a new message object and update the messages state.

5. Processing Messages with the ChatGPT API

To process the user's message and generate responses from the ChatGPT API, we need to make API requests. We will create a function called processMessageToChatGPT, which will handle the API request. We will also format the messages for the API, including converting the sender field to match the API's expected format.

6. Formatting Messages for the API

The ChatGPT API expects the messages to be formatted in a specific way. We need to format our messages array to include the necessary role and content fields. We will use the map function to iterate over the messages and create a new array with the required structure.

7. Making the API Request

In this section, we will make the API request to the ChatGPT API using the formatted messages array. We will use the fetch function to send a POST request to the API endpoint, including the necessary headers and body. We will also handle the response from the API.

8. Displaying API Responses

Once we receive a response from the ChatGPT API, we want to display it in the chat interface. We will update the messages state to include the API response as a new message object. This will allow the chatbot to show the response from ChatGPT alongside the user's messages.

9. Adding a Typing Indicator

To provide a better user experience, we can add a typing indicator to simulate ChatGPT thinking or typing. We will create a state variable called typing and set it to true when the API request is initiated. This will trigger the display of a typing indicator in the chat interface. Once the response is received, we will set typing back to false.

10. Customizing ChatGPT's Language

In the final section, we will explore how to customize ChatGPT's language using Prompts. We can define a system message at the beginning of our conversation to specify how we want ChatGPT to respond. We can use prompts like "speak like a pirate" or "explain like I'm a 10-year-old". This allows us to control the tone and style of the conversation according to our specific requirements.

Overall, this tutorial will guide You through the process of building a chatbot with the ChatGPT API. We will cover the necessary steps, from setting up the frontend to processing messages and displaying responses. Adding advanced features like a typing indicator and customizing ChatGPT's language will enhance the chatbot's functionality and user experience.
