How does readable-stream.writable work?

readable-stream.Writable works by representing a writable stream in Node.js, and providing methods and properties for writing data to the stream. When used in a Node.js application, readable-stream.Writable can be used to create a new writable stream object, which can be used to write data to a destination, such as a file or network socket. The readable-stream.Writable class provides a number of methods and events for working with writable streams, including: write(chunk[, encoding][, callback]): writes a chunk of data to the stream, with an optional encoding and callback function. end([chunk][, encoding][, callback]): signals the end of the stream, with an optional final chunk of data, encoding, and callback function. on(event, listener): registers an event listener for a specific event, such as "data", "drain", or "error". once(event, listener): registers a one-time event listener for a specific event. destroy([error]): destroys the stream, with an optional error object. These methods and events can be used to write data to the stream, handle errors or other events that occur during the writing process, and signal the end of the stream. Note that readable-stream.Writable is part of the readable-stream library, which provides a set of utility classes and functions for working with readable and writable streams in Node.js.

const { Writable } = require("readable-stream");

const myWritable = new Writable({
  write(chunk, encoding, callback) {
    console.log(chunk.toString());
    callback();
  },
});

myWritable.write("Hello, world!");

In this example, we first import the readable-stream library and assign the Writable class to a variable for convenience. We then create a new writable stream called myWritable, using the Writable constructor function. We pass in an options object with a write method that will be called every time data is written to the stream. The write method simply logs the data to the console and calls the callback function to indicate that the write operation has completed. We then write the string "Hello, world!" to the myWritable stream, using the write method of the Writable object. When executed, this code will log the string "Hello, world!" to the console, indicating that the data was successfully written to the stream. Note that this is just a simple example, and readable-stream.Writable can be used in more complex scenarios, such as creating custom writable streams that write data to a specific destination or implement custom behavior for handling errors or other events that occur during the writing process.
