Hello @thatmarcboi! I'm Dosu, a friendly bot designed to assist you with your queries, bugs, and more while we wait for a human maintainer to join us. I'm here to help make your experience with our repository as smooth as possible. Looking forward to assisting you!

Based on the information I found, the current version of the gpt4-pdf-chatbot-langchain codebase does not support text streaming functionality similar to chat.openai.com. The code handles HTTP POST requests and responds with a single response for each request. It does not maintain a persistent connection for streaming responses. You can refer to the relevant code in the pages/api/chat.ts file.

However, there is a similar solved issue in the repository, Unable to stream response, where the user was directed to a fork of the project by groovybits, which still has the streaming functionality. You might find this fork useful.

Additionally, the gpt4-pdf-chatbot-langchain project includes a library that can be used to implement text streaming functionality. The library is "@microsoft/fetch-event-source". This library is a polyfill for the EventSource API (also known as Server-Sent Events), which can be used to stream text data from a server to a client. You can refer to the package.json file for more details.

Here is a basic example of how you might use it:

import { FetchEventSource } from '@microsoft/fetch-event-source';

const eventSource = new FetchEventSource('https://example.com/stream');

eventSource.onmessage = (event) => {
  console.log(event.data);
};

eventSource.onerror = (error) => {
  console.error('An error occurred:', error);
};

In this example, 'https://example.com/stream' would be the URL of your server-side endpoint that sends the text stream. The onmessage event handler is called whenever a new piece of data is received from the stream, and the onerror event handler is called if an error occurs.

I hope this information is helpful. If you have any other questions or need further clarification, feel free to ask.
