Streaming zip to a file keeps Deno hanged for a moment

[sant123]

Hello! I'm running this code:

import { BlobWriter, TextReader, ZipWriter } from "jsr:@zip-js/zip-js";

// ----
// Write the zip file
// ----

// Creates a BlobWriter object where the zip content will be written.
const zipFileWriter = new BlobWriter();

// Creates a TextReader object storing the text of the entry to add in the zip
// (i.e. "Hello world!").
const helloWorldReader = new TextReader("Hello world!");

// Creates a ZipWriter object writing data via `zipFileWriter`, adds the entry
// "hello.txt" containing the text "Hello world!" via `helloWorldReader`, and
// closes the writer.
const zipWriter = new ZipWriter(zipFileWriter);
await zipWriter.add("hello.txt", helloWorldReader);
await zipWriter.close();

// Retrieves the Blob object containing the zip content into `zipFileBlob`. It
// is also returned by zipWriter.close() for more convenience.
const zipFileBlob = await zipFileWriter.getData();
const zipFile = await Deno.open("some.zip", { create: true, write: true });

await zipFileBlob.stream().pipeTo(zipFile.writable);
console.log("Done!");

Notice how the message is printed, but something is hanging the process to exit. Do I need to close something? I do not know what is happening here.

Thanks!

You have to call await zip.terminateWorkers() or reduce the termination delay of web workers (5s by default) by calling zip.configure({ terminateWorkerTimeout: delay }).

• await terminateWorkers()

import { BlobWriter, TextReader, ZipWriter, terminateWorkers } from "jsr:@zip-js/zip-js";

try {
  // ...
} finally {
  await terminateWorkers();
}

• configure({ terminateWorkerTimeout: delay })

import { BlobWriter, TextReader, ZipWriter, configure } from "jsr:@zip-js/zip-js";

configure({ terminateWorkerTimeout: 0 }); // no delay
// ...
