Proper way of downloading a large file using NodeJS and Axios (NodeJS 8 and earlier)

axios_download_node8.ts

export async function downloadFile(fileUrl: string, outputLocationPath: string) {
   const writer = createWriteStream(outputLocationPath);
 ​
   return Axios({
     method: 'get',
     url: fileUrl,
     responseType: 'stream',
   }).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;
       });
     });
   });
 }

Thank you so much. It helped me a lot

Thanks! If you use NodeJS 10+, take a look at a much simpler method here: https://gist.github.com/csotiriou/93822047febd7a5c018d2fab1ffcb8c0 - which essentially is the same thing, only using Node's more modern approach

Thank you for that too!
Sadly for the limitation I use node8 for now, but I'll try that if I use node10+ next time!
