Laravel’s useStream Hook — Real-Time Streaming Made Simple

Laravel continues to push the boundaries of modern web development, and one of the most exciting recent additions is the useStream hook. Tailored for real-time, ChatGPT-style streaming experiences, this new feature empowers frontend developers using React or Vue to effortlessly consume streamed responses from the Laravel backend.

Whether you're building a chat interface, an AI response system, or any UI that demands live updates, useStream offers a seamless and intuitive API for handling streaming data.

🌊 What is useStream?

At its core, useStream is a custom hook that enables components to interact with Laravel’s streamed responses. It's part of Laravel’s official frontend ecosystem and is available via:

• @laravel/stream-react (for React)
• @laravel/stream-vue (for Vue)

The feature is especially useful for applications where responses are streamed in chunks—perfect for AI prompts, chat UIs, or live data feeds.

⚙️ Key Features

Here’s what makes useStream powerful:

✅ Real-Time Streaming

Watch your UI update as each chunk of data arrives—ideal for interactive conversations or streamed AI responses.

✅ Framework Flexibility

Compatible with both React and Vue, making it easier to adopt in existing or new projects.

✅ Intuitive API

The hook exposes helpful state and methods:

• data – The streamed content
• isFetching – Indicates if a connection is initializing
• isStreaming – Tracks if data is currently streaming
• send – Sends input to the stream endpoint

✅ Customizable Behavior

The second argument to useStream allows deep customization:

• id: Share streams across components
• initialInput: Define default payload
• headers and csrf: Send secure, customized requests
• Lifecycle Callbacks: onResponse, onData, onCancel, onFinish, and onError

✅ Multi-Component Support

Use the same stream across different parts of your app by defining a shared id.

✅ POST-Based JSON Communication

All data sent with send() uses POST requests. Ongoing connections are automatically canceled before new ones start—ensuring clean state transitions.

🧠 Example: Using useStream in React

Here’s a simple example where a message is streamed from the server:

import { useStream } from "@laravel/stream-react";

function App() {
  const { data, isFetching, isStreaming, send } = useStream("chat");

  const sendMessage = () => {
    send({ message: `Current timestamp: ${Date.now()}` });
  };

  return (
    <div>
      <div>{data}</div>
      {isFetching && <div>Connecting...</div>}
      {isStreaming && <div>Generating...</div>}
      <button onClick={sendMessage}>Send Message</button>
    </div>
  );
}

This example initiates a new stream every time the button is clicked and displays the streamed data in real-time.

📡 Bonus: useEventStream for SSE

Laravel also offers a useEventStream hook for consuming Server-Sent Events (SSE). If your backend supports event broadcasting over HTTP, this can be a lightweight alternative for real-time UI updates.

🔥 Perfect for...

The useStream hook shines in scenarios like:

• AI chatbots and assistants
• Live notifications and logs
• Streaming newsfeeds
• Real-time translation apps
• Code and text generation UIs (à la ChatGPT)

🚧 Status: Beta (But Promising)

useStream is currently in beta, so its API may evolve as it matures. Still, it’s stable enough for experimentation and production use with caution. Stay updated via the official Laravel GitHub repository and documentation.
