How to decode the base64 to native binary data? about react-native-fetch-blob

Hi @itinance , as you may know, I'm still working on it ( on v0.5.0 branch ) 😃

Ah i think this relates to #2

Sounds really nice! Can you tell some details of this upcoming feature? In my case i think about a method "downloadFileToLocalStorage( uri, destination )" and the file would be downloaded from remote uri and placed in local storage.
Would your new feature be the same more or less? :)

@itinance , I'm planning to add a config API so that you can do this

RNFetchBlob.config({
    path : 'path-to-local-storage'
})
.fetch('GET', ... ,{...})
// it will be a file path rather than BASE64 string
.then( (pathOfDownloadedFile) => ... )

I'm also consider whether add some other APIs that simply wraps the original ones, such as

RNFetchBlob.downloadToStorage(config, path)
RNFetchBlob.uploadFromStorage(config, path)

but these wrapper APIs may not be added in v0.5.0.

That sounds really great!

Was this developed after all? I have exactly this use case here :)
(instead of dowloading the file, I actually receive a binary of a mp3 in the response of an HTTP request, then save to react-native-fs, and I want to play it later with react-native-sound).
