@icanvas/webpack/utils/zip.js

这是icanvas的默认webpack打包配置

const fs = require('fs-extra');
const archiver = require('archiver');
module.exports = function(from, to, filelist) {
	return new Promise(function(resolve, reject) {
		let zip = archiver('zip', { zlib: { store: true } });
		let output = fs.createWriteStream(to);
        output.on('close', resolve);
		zip.pipe(output);
		zip.directory(from, false);
		if (filelist) zip.file(filelist, { name: 'option.json' });
		zip.finalize();
	});
};
