streamToBuffer

Converts a readable stream into a buffer. This is useful when you need to process the entire content of a stream as a single buffer.

const { streamToBuffer } = require('@aws-sdk/util-stream-node');
const { Readable } = require('stream');

const readableStream = Readable.from(['Hello', ' ', 'World']);

streamToBuffer(readableStream).then(buffer => {
  console.log(buffer.toString()); // Output: Hello World
});

streamToString

Converts a readable stream into a string. This is useful when you need to process the entire content of a stream as a single string.

const { streamToString } = require('@aws-sdk/util-stream-node');
const { Readable } = require('stream');

const readableStream = Readable.from(['Hello', ' ', 'World']);

streamToString(readableStream).then(string => {
  console.log(string); // Output: Hello World
});

bufferToStream

Converts a buffer into a readable stream. This is useful when you need to process a buffer as a stream.

const { bufferToStream } = require('@aws-sdk/util-stream-node');
const buffer = Buffer.from('Hello World');

const stream = bufferToStream(buffer);

stream.on('data', chunk => {
  console.log(chunk.toString()); // Output: Hello World
});
