Building an AI Chatbot Using Vue, Node, and OpenAI

In today's digital age, chatbots have become an essential tool for businesses to engage with their customers. They provide a quick and efficient way to answer customer queries and provide support. In this tutorial, we will walk You through the process of building a functional chatbot using Vue, Node, and OpenAI.

Setting up the View and Node.js Project

The first step in building our chatbot is to set up a new Vue and Node.js project. We will be using the Vue CLI to Create our project. Here are the steps to follow:

1. Make sure you have Node.js and npm installed on your system.
2. Install the Vue CLI globally by running the following command: npm install -g @vue/cli. Make sure you are using sudo to install it globally.
3. Create a new Vue project by running vue create ai-chat and choose the default settings.
4. Navigate to our project AI Chat and install the necessary dependencies for the front end by running the following command: npm install axios. We will be using Axios to fetch APIs.

Installing Dependencies for the Front End

Now that we have set up our Vue project, we need to install the necessary dependencies for the front end. Here are the steps to follow:

1. Create a new Node.js project in a separate folder. We will name this as chat-gpt-backend.
2. Move to the chat-gpt-backend folder and execute the following command: npm init -y. It will create a Package.json file for us.
3. Install the necessary dependencies for the back end. Our main dependencies are Express and Cors. Run the following command: npm install express cors.
4. Create a new file index.js. In this code, we set up an Express server, enable Cors, and configure the body-parser Middleware to parse JSON requests. It also defines a post route for the chatbot that uses the ChatGPT controller's askToChatGPT function.

Creating the Back End

Now that we have installed the necessary dependencies for the back end, we need to create the ChatGPT controller. Here are the steps to follow:

1. Create a new file called chatgpt.controller.js. In this code, the askToChatGPT function handles incoming chat requests, creates an OpenAI API instance, and sends a message through the ChatGPT API. The AI-generated response is then sent back to the front end.
2. Create a .env file in the chat-gpt-backend folder and add your ChatGPT API key here.

Adding the ChatBox View

Now that we have set up our back end, we need to add the ChatBox view to our front end. Here are the steps to follow:

1. Create a new file called ChatBox.vue in the src/components folder and add the necessary code. This code defines the sendMessage method, which sends user messages to the back end server and appends the AI-generated response to the chat interface. It uses the Axios library to make an HTTP post request to the chatbot endpoint of the back end server, passing the user message as a parameter. It then processes the response and adds the AI-generated message to the messages array.
2. Add the template for our ChatBox. This template defines the structure of the chat interface, including the chat container, message box, input field, and ask button.
3. The style section contains CSS code to style the chat interface, including font sizing, Dimensions, and some UI changes to make it look like Facebook-style messenger.

Modifying the App View

Now that we have added the ChatBox view, we need to modify the App view to display our ChatBox component as the main App view. Here are the steps to follow:

1. Modify the App.vue file to import the ChatBox component and add it to the template.

Running the Chatbot

Now that we have set up our front end and back end, we can run our chatbot. Here are the steps to follow:

1. In the back end folder, execute the following command: node index.js.
2. Similarly, in the AI chat folder, run the following command: npm run serve.
3. Open your browser and visit localhost:8080 (or the port of your choice). You can now Interact with your AI Chatbot.

Customizing and Improving the Chatbot

Now that we have a fully functioning chatbot, we can customize and improve it. Here are some ideas:

• Modify the styling and layout to match your Website design.
• Add more features and improvements to make your chatbot even more powerful and interactive.
