How to download file stream and writeFile with Node.js axios?

Spread the love

To download file stream and writeFile with Node.js axios, we set the responseType.

For instance, we write

const response = await axios({
  method: "get",
  url: "https://example.com/my.pdf",
  responseType: "stream",
});
response.data.pipe(fs.createWriteStream("/temp/my.pdf"));

to call axios to make a get request.

We set the responseType to 'stream' to download the data as a stream.

And then we call response.data.file with a write stream to pipe the read stream we get from response to the write stream to write the response data to the my.pdf file.
