why is your archive splited up in multiple chunks? anyhow. i would recommend you to keep using the server if possible to save the zip instead of emulating a server using streamsaver.js and a service workers

but if you insist on using streamsaver anyway then you would have to make something like:

const chunks = [
    'https://example.com/',
    'https://example.com/',
]

function concatenateRequests(requests) {
    const ts = new TransformStream()
    const pump = () => {
        const it = requests.next()
        if (it.done) return ts.writable.close();
        fetch(it.value).then(res => {
            console.log(res.body);
            return res.body.pipeTo(ts.writable, { preventClose: true })
        }).then(pump, ts.writable.abort.bind(ts.writable));
    }

    pump();

    return ts.readable;
  }

  concatenateRequests(chunks.values()).pipeTo(streamSaver.createWritableStream('archive.zip'))
