How can I handle streaming data in an Express application?

You can handle streaming data in Express by using middleware like body-parser for parsing incoming request bodies and streams.

Can you give me an example of streaming data from a file?

Sure! You can use Node.js's fs module to create a readable stream and pipe it to the response. Here's a simple example:

const fs = require('fs');
const express = require('express');
const app = express();

app.get('/stream', (req, res) => {
    const stream = fs.createReadStream('path/to/your/file.txt');
    stream.pipe(res);
});

app.listen(3000, () => console.log('Server running on port 3000'));

What if I want to handle multiple streams?

You can use EventEmitter to manage multiple streams and listen for data events. You can also use Promise.all to handle multiple streams concurrently.

Are there any performance considerations I should be aware of?

Yes, be mindful of memory usage and backpressure. Use streams efficiently to avoid overwhelming your server with too much data at once.
