I used react-native-fetch-blob to download file excel from api. I can see it's downloading successfully but as you know On iOS platform the directory path will be changed every time you access to the file system.

I show the path by console.log:

"/Users/admin/Library/Developer/CoreSimulator/Devices/749E7AAA-F568-4F56-9606-FF23E84946CF/data/Containers/Bundle/Application/95C3997D-BBB3-4FB3-94C4-ADB0331940B2/Bus_Booking.app/MYFILE.xlsx".

But when I go to the folder of the device, there are no files to see. How can I download and write the path where a user can see their device?

You need to save file to a directory, else it will be saved in a temporary directory only available to app.

const baseDir = RNFetchBlob.fs.dirs.DownloadDir;
const path = `${baseDir}/my-file.png`;
RNFetchBlob.fs.writeFile(path, <temp file path>, 'uri');

react-native-fetch-blob repo is not maintained anymore. Use rn-fetch-blob

  • i want to save to iphone or ipad not android device – Hồ Quốc Huy Oct 03 '18 at 01:39
  • @HồQuốcHuy the path you mentioned in your question is the tmp path `/Users/admin/Library/Developer/CoreSimulator/Devices/749E7AAA-F568-4F56-9606-FF23E84946CF/data/Containers/Bundle/Application/95C3997D-BBB3-4FB3-94C4-ADB0331940B2/Bus_Booking.app/MYFILE.xlsx` – Fawaz Oct 03 '18 at 07:16
  • the path you write is a dynamic path. So i used react native FileViewer to open file and user can save it to their device. – Hồ Quốc Huy Oct 03 '18 at 07:39
