What is the best way to upload large file (video)?

Hi,

I’m using Storage.put to upload video files to S3 but the app crashes if file size is large. Here is the code:

const fileData = await RNFetchBlob.fs.readFile(videoUri, 'base64')
const buffer = new Buffer(fileData, 'base64')
Storage.put(fileName, buffer, ...)

Does amplify support multi-part upload yet? If not, what’s the workaround?

Thanks!

Storage.put supports Managed upload, splitting the file into chunks and uploading into batches. But the problem here is, to call Storage.put we have to pass the blog, which means we have read the full file. Reading full file causes out of memory issues and the app crashes. Here is one solution which I built & tried. https://dev.to/walvekarnikhil/reactnative-large-file-upload-using-amplify-s3-17ho
