Working with Streams
Buffers are frequently used in NodeJS streams for handling data chunks efficiently. Streams in NodeJS allow for the continuous flow of data between sources, sinks, and transformations. Buffers are often used to store and manipulate data chunks as they pass through streams.
const fs = require('fs');
const readStream = fs.createReadStream('input.txt');
const writeStream = fs.createWriteStream('output.txt');
readStream.on('data', (chunk) => {
// Process chunk (stored in buffer)
writeStream.write(chunk);
});
What is the purpose of the Buffer class in Node ?
In Node, the Buffer
class plays a crucial role in handling binary data, allowing developers to work with raw binary data directly. The Buffer
class provides a way to create, manipulate, and convert binary data efficiently, making it essential for various tasks such as file I/O, network communication, cryptography, and data manipulation. Let’s explore the key purposes and functionalities of the Buffer
class in Node.
