How to Build a Chatbot with Next.js, TailwindCSS, and OpenAI Chat Completion API - Full Tutorial

Introduction

Are you interested in creating a dynamic and responsive chatbot? In our latest YouTube tutorial, we walk you through building a chatbot using Next.js, TailwindCSS, and the OpenAI Chat Completion API. This step-by-step guide is perfect for developers of all levels looking to enhance their web development skills and create engaging user experiences.

Technologies Used

1. Next.js: A powerful React framework that enables server-side rendering, static site generation, and easy API integration. Next.js is known for its performance and scalability, making it an excellent choice for modern web applications.

2. TailwindCSS: A utility-first CSS framework that allows for rapid styling and customization. TailwindCSS provides a responsive and cohesive design system without writing traditional CSS, streamlining the development process.

3. OpenAI Chat Completion API: This API leverages OpenAI's advanced language models to generate human-like responses, enabling the creation of intelligent and interactive chatbots. Integrating this API enhances the conversational capabilities of your chatbot.

Getting Started

To give you a taste of what you'll learn in the tutorial, here’s a snippet of the code we’ll be working on:

export async function chatCompletion(chatMessages: Message[]) {
// Create chat with system prompt
  const chat = [
    { role: "system", content: "You're a helpful assistance" },
    ...chatMessages,
  ];

  // API Request
  const completion = await openAI.chat.completions.create({
    messages: chat,
    model: "gpt-4o-mini",
  });

  // Completion result (new message)
  console.log(completion.choices[0]);
  return completion;
}

Explanation:

Function Definition and Parameter:

The function chatCompletion is an asynchronous function that takes an array of Message objects as its parameter. Each Message represents a chat message exchanged between the user and the assistant.
Creating the Chat Array:

The chat array is created by combining a system prompt ("You're a helpful assistant") with the chatMessages provided as input. This system prompt helps guide the assistant's behavior in generating responses.
API Request to OpenAI:

The function makes a request to the OpenAI API using the openAI.chat.completions.create method. This request includes the chat array and specifies the model gpt-4o-mini to be used for generating the response.

Handling the Completion Result:

Once the API returns a response, the first choice of the generated completion (i.e., the new message from the assistant) is logged to the console.

The function then returns the entire completion object.

This code snippet demonstrates how to create a chat session with a system prompt, send it to the OpenAI API for generating a response, and handle the API's completion result.
