Streaming ChatGPT Responses with Express.js: A Seamless Integration

To fully harness the power of ChatGPT and provide a truly immersive user experience, it‘s essential to leverage the power of streaming technology. In this section, we‘ll explore how to implement a streaming solution using the versatile Express.js framework, a popular Node.js web application framework.

Setting the Stage: Establishing the Express.js Server

Let‘s begin by setting up a basic Express.js server to handle the integration with the OpenAI API and the streaming of ChatGPT responses.

import express from "express";
import { Configuration, OpenAIApi } from "openai";
import { pipeline } from "node:stream/promises";
import dotenv from "dotenv";

dotenv.config();

const app = express();
const port = 3000;

app.use(express.json());

// Endpoint for streaming ChatGPT responses
app.post("/chatapi", async (req, res) => {
  try {
    const configuration = new Configuration({
      apiKey: process.env.OPENAI_API_KEY,
    });
    const openai = new OpenAIApi(configuration);

    const response = await openai.createChatCompletion({
      model: "gpt-3.5-turbo",
      messages: [
        {
          role: "user",
          content: req.body.message || "Say hello.",
        },
      ],
      temperature: 0,
      max_tokens: 2048,
      n: 1,
      stream: true,
    });

    // Pass the streaming response from OpenAI directly to the client
    await pipeline(response.data.response, res);
  } catch (err) {
    console.error(err);
    res.status(500).send("An error occurred while processing the request.");
  }
});

app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});

In this setup, we‘re creating a POST endpoint at /chatapi that will handle the streaming of ChatGPT responses. Let‘s break down the key steps:

Configure the OpenAI API Client: We start by configuring the OpenAI API client with the provided API key, which will allow us to interact with the ChatGPT model.
Implement the Streaming Endpoint: The /chatapi endpoint is where the magic happens. When a client makes a POST request to this endpoint, we‘ll use the OpenAI API to generate a ChatGPT response, but with one crucial difference: we set the stream option to true.
Pass the Streaming Response to the Client: By setting the stream option to true, the OpenAI API will respond with a streaming response, which we can then pass directly to the client using the pipeline function from the Node.js Streams API.

This setup lays the foundation for a seamless integration of ChatGPT into your web application, setting the stage for a truly immersive and responsive user experience.

Consuming the Streaming Response on the Client-Side

Now that we have the server-side setup in place, let‘s explore how to handle the streaming response on the client-side. For this example, we‘ll be using Vue.js, a popular JavaScript framework, to showcase the client-side implementation.

<script setup>
import { ref } from "vue";

const chatMessage = ref("");
const chatQuestion = ref("");

async function startChat(question) {
  chatMessage.value = "Loading...";

  try {
    const response = await fetch("/chatapi", {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify({ message: question }),
    });

    const reader = response.body?.pipeThrough(new TextDecoderStream()).getReader();

    while (reader) {
      const { value, done } = await reader.read();
      if (done) break;

      const chunks = value
        .replaceAll(/^data: /gm, "")
        .split("\n")
        .filter((c) => Boolean(c.length) && c !== "[DONE]")
        .map((c) => JSON.parse(c));

      for (const chunk of chunks) {
        const content = chunk.choices[0].delta.content;
        if (content) {
          chatMessage.value += content;
        }
      }
    }
  } catch (err) {
    console.error(err);
    chatMessage.value = "An error occurred. Please try again later.";
  }
}
</script>

<template>
  <div class="chat-container">
    <div class="chat-message">{{ chatMessage }}</div>
    <div class="chat-input">
      <input v-model="chatQuestion" placeholder="Ask a question" />
      <button @click="startChat(chatQuestion)">Send</button>
    </div>
  </div>
</template>

In this client-side code, we‘re using the Fetch API to make a POST request to the /chatapi endpoint on the server. When the response is received, we use the pipeThrough method to decode the streaming data and process it in a while loop.

The key steps are:

Retrieve the Response Reader: We use response.body?.pipeThrough(new TextDecoderStream()).getReader() to get a reader from the response body, which will allow us to consume the streaming data.
Process the Streaming Data: Inside a while loop, we read the data from the reader, parse the JSON-encoded chunks, and update the chatMessage reactive variable with the content.
Handle Errors: We wrap the entire process in a try-catch block to ensure we can gracefully handle any errors that may occur during the streaming process and provide appropriate feedback to the user.

By combining the server-side streaming implementation with the client-side handling of the streaming response, you can create a seamless, real-time experience for your users when interacting with ChatGPT within your web application.
