S3 Multipart upload React Native

[jmparsons]

Can React Native do multipart / managed s3 uploads?

Trying to upload very large files from react native, 500mb+.

I'm not a React Native expert, so you might want to cross-post this to Stack Overflow to see if you can get more opinions.

It looks like React Native just recently added support for blobs to their implementation, but the linked PR does not seem to have been included in any released version yet. Without Blob/File support, I believe you would need to get the contents of the file into JS memory and upload them as buffers or typed arrays. With files of that size, though, you might want to look into a native code solution that uploads a file using a presigned POST form or a presigned PutObject URL. You can also try the aws/amplify library, which has React Native-specific S3 abstractions.

Wow it finally got merged. Thanks @jeskew

@jmparsons Have you found any solution to this yet? Here is the piece of code I'm using to upload a large file but I still got Out of memory exception:

const data = await RNFetchBlob.fs.readFile(videoUri, 'base64')
Storage.put(fileName, data, ...)
