easy-transform-stream

Create a transform stream using await instead of callbacks

The built-in stream.Transform constructor forces you to deal with a callback interface. It's much nicer to just be able to await and return a value.

This package can be thought of as a modern version of through2.

Install

npm install easy-transform-stream

Usage

import transformStream from 'easy-transform-stream';

const stream = transformStream(async chunk => {
	const newChunk = await modifyChunk(chunk);
	return newChunk;
});
