What are some examples of using streams in Node.js?

Can you give me some examples of using streams in Node.js?

Sure! Node.js streams are used to handle reading and writing data in a continuous flow. For example, you can use a readable stream to read data from a file.

How do I create a readable stream from a file?

You can create a readable stream using the 'fs' module. Here's a simple example:

const fs = require('fs');
const readableStream = fs.createReadStream('example.txt');

This will create a stream that reads data from 'example.txt'.

What about writable streams? Can you show me an example?

Absolutely! You can create a writable stream like this:

const fs = require('fs');
const writableStream = fs.createWriteStream('output.txt');

You can then write data to 'output.txt' using the write method.

Are there any other types of streams I should know about?

Yes, there are also duplex streams, which can read and write data, and transform streams, which can modify the data as it is read or written.
