Create a single zip file incrementally? about node-archiver

[spinlud]

Appending a Stream instead of a Buffer seems to be a possible solution. Any thought?

import {PassThrough} from 'stream';
import archiver from 'archiver';

(async () => {
	const inputStream = new PassThrough();
	const outputStream = new PassThrough(); // Pass this to some upload function
	const archive = archiver('zip', {
		zlib: { level: 9 }
	});

	archive.pipe(outputStream);
	archive.append(inputStream, { name: `myfile.txt` });

	// Assume this data can't fit in memory all at once, so it should be added incrementally
	for (let i = 0; i < 100; i++) {
		const textData = `data-${i}\n`;                
		inputStream.write(textData, 'utf8')
	}

	inputStream.end();	
	await archive.finalize();	
})();
