How to read a file from a gzip file

[TickFairy]

hello, I want to decompress a gizp file which contains a file named xxx.json, how can I get the content of xxx.json?
I find gunzip dones‘t have onfile method

    const reader = new FileReader();
    reader.readAsArrayBuffer(file);
    reader.onerror = () => {};
    reader.onload = () => {       
      const bytes = new Uint8Array(reader.result as ArrayBuffer);
      console.log(bytes);
      const gunzip = new AsyncGunzip();
      gunzip.ondata = (err, data, final) => { // onfile?
        if (err) {
          console.error(err);
        } else {
          console.log(fflate.strFromU8(data));
        }
      };
      gunzip.push(bytes);
    };

Since you want the JSON data, you can do this without streams. Try:

// just after const bytes = new Uint8Array(...);
const jsonString = strFromU8(gunzipSync(bytes));
