output to base64 string

[fgrs]

is this currently possible?

Not currently, but you can use a module like react-native-fs to read the output file that was created by react-native-image-resizer. See readFile method documentation. Beware of large files, it can be quite hazardous to store such files in a base64 string.

I did it the way you suggested but now for image resized and saved in

file:/data/data/com.app/cache/1472039430399.JPEG

I get following error in readFile:

Error: ENOENT: no such file or directory, open 'file:/data/data/com.app/cache/1472039430399.JPEG'(…)

[fgrs]

is this path correct? file:/data/data/com.app/cache/1472039430399.JPEG

Not sure, you should double-check if the file is really on the device or not using for example the android tools in Android Studio :)

Maybe too late for you, but it can help others. storing local files on real devices will give dynamic document/caches directories. To find the correct app directory, us react-native-fs:

var RNFS = require('react-native-fs');
var filepath = RNFS.DocumentDirectoryPath + '/'+yourfilename;
var readfile = RNFS.readFile(filepath, 'utf8');

the 'DocumentDirectoryPath' will give you your current documentpath.

Any update?

If anyone runs into this, @virgial is mostly correct, although you need to use

var readfile = RNFS.readFile(filepath, 'base64')

instead of utf8.

Here's my working example:

           const resizedImageUri = await ImageResizer.createResizedImage(
            `data:image/jpeg;base64,${response.data}`,
            400,
            400,
            "JPEG",
            100,
            0
          );
          const base64Data = await RNFS.readFile(
            resizedImageUri.path,
            "base64"
          );
          this.props.onPhotoUpload(`data:image/png;base64,${base64Data}`);

This works: 'data:image/jpeg,'+image The code expects a comma before the base64 image, for some reason...

@mickael-h Your solution is not suited for the question. You might be replying for 'how to upload base 64'
