React-native-fs: downloadFile example for v2.x

Created on 5 Oct 2016 · 8Comments · Source: itinance/react-native-fs

This example worked in v1.5.1, but seems to have broken since v2.0.0:

RNFS.downloadFile(url, path).then(res => {
  this.setState({ downloaded: true });
});

Could you add a working example of downloadFile usage in the README?

As per the document,

RNFS.downloadFile(url, path).promise.then(res => {
  this.setState({ downloaded: true });
});

seems to be invalid, the following one works as of today.

RNFS.downloadFile({fromUrl:url, toFile: path}).promise.then(res => {
  this.setState({ downloaded: true });
});

Thank you @kiliwalk

When you trigger this function, what's the default behavior per OS?

I'm expecting that when the user taps the download button, it will open a file browser to let the user choose the download location. So in the future the user can open the file from his phone from outside the app.

What will it actually do on iOS and on Android?

ES6 style

const downloadFile = async () =>{ try{ const data = await RNFS.downloadFile(url, path).promise; if(data){ this.setState({ downloaded: true }); } }catch(error){ console.log('error', error) } }
