So I am basically trying to use axios to download a image from a url, but I get this error:
TypeError: streamResponse.data.pipe is not a function
My function for doing this image download is below (note that this is inside a class):
/**
* Download poster
*/
async downloadPoster() {
// Writer stream where we want to download the poster image
const writer = fs.createWriteStream(this.poster.file);
// This grabs the second part of the image url that we want
const resultsResponse = await axios({
url: this.poster.url,
method: 'GET',
responseType: 'json',
adapter: httpAdapter
});
// Zero results
if (resultsResponse.data.total_results <= 0) {
logger.log(language[Config.language].posterNotFound + this.movie.title, 'error');
return false;
}
// Create the poster download URL
var posterDownloadUrl = new URL(Config.api.posterUrl + resultsResponse.data.results[0].poster_path);
const streamResponse = await axios({
url: posterDownloadUrl,
method: 'GET',
responseType: 'stream',
adapter: xhrAdapter
});
// Write data
streamResponse.data.pipe(writer);
return new Promise((resolve, reject) => {
writer.on('finish', resolve);
writer.on('error', reject);
});
}
I assume that the adapter for a stream response is the xhr one. Anyways, I have tried both adapters and both gives the exact same error. Both requests does happen though (I can see them in the devtools).
And so there’s no confusion, I have the adapters imported at the top of the file:
const httpAdapter = require('axios/lib/adapters/http');
const xhrAdapter = require('axios/lib/adapters/xhr');
What could I be doing wrong here?

Got it working by sending the download request over to the main thread. Don’t know why, but seems you can’t access the axios data from a stream in the renderer.js
file. Got it working now though after having a look here:
