How to Use Streams in NodeJS:
NodeJS provides a built-in stream
module, which includes various types of streams such as Readable
, Writable
, Duplex
, and Transform
. You can create streams using these classes and pipe them together to create data processing pipelines.
const { Readable, Writable } = require('stream');
// Create a Readable stream
const readableStream = new Readable({
read(size) {
// Implement the read method
}
});
// Create a Writable stream
const writableStream = new Writable({
write(chunk, encoding, callback) {
// Implement the write method
}
});
// Pipe the Readable stream to the Writable stream
readableStream.pipe(writableStream);
Explain the concept of streams in Node
Streams in Node provide an efficient way to handle data flowing through an application. They allow you to read from or write to a source continuously, processing chunks of data as they become available, without needing to load the entire dataset into memory at once.
