return Axios({

}).then(response => {
//ensure that the user can call `then()` only when the file has
//been downloaded entirely.
return new Promise((resolve, reject) => {
response.data.pipe(writer);
let error = null;
writer.on('error', err => {
error = err;
writer.close();
reject(err);
});
writer.on('close', () => {
if (!error) {
resolve(true);

//no need to call the reject here, as it will have been called in the
//'error' stream;
});
});
});
}
This way, you can call downloadFile(), call then() on the returned promise, and making sure that the downloaded file will have completed processing.
Or, if you use a more modern version of NodeJS, you can try this instead:
import * as stream from 'stream';
import { promisify } from 'util';
const finished = promisify(stream.finished);
export async function downloadFile(fileUrl: string, outputLocationPath: string): Promise<any> {
const writer = createWriteStream(outputLocationPath);
return Axios({
method: 'get',
url: fileUrl,
responseType: 'stream',
}).then(async response => {
response.data.pipe(writer);
return finished(writer); //this is a Promise
});
