How to convert docx bytes to file Node Js with axios

Question

I am retrieving a docx file from an endpoint a trying to create a file from it. I get a file but its not readable. maybe it's a problem with the format I am recieving the file.

this is how I retrieve the information a create the file:

const response = await axios.post(
  `${process.env.TEMPLATE_HOST}template/data/export`,
  {dataId, clientId},
)

fs.writeFileSync(F.path.public(rowFiltered[0]["Files(s) Name"]), response.data);

and this is part of the data I recieve

                                                             ��_rels/.relsP9��Ruڽ�w

I've tried to do it with php and it creates the file correctly. the php file size is 47KB and the nodejs is 83KB, but compare part of the information and looks the same.

$fp = fopen('data.docx', 'w');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $templateURl);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER,
            array(
                'Content-Type: application/json',
                'Content-Length: ' . strlen($data_string),
            )
        );
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec($ch);
curl_close ($ch);
echo strlen($server_output);
fwrite($fp, $server_output);
fclose($fp);

any help is appreciated thanks.

Not sure about this, but this could be because of some option that needs to be set on axios.

Maybe try:

const response = await axios.request(
  responseType: 'stream',
  url: `${process.env.TEMPLATE_HOST}template/data/export`,
  method: 'post',
  data: {dataId, clientId},
)

fs.writeFileSync(F.path.public(rowFiltered[0]["Files(s) Name"]), response.data);
