Multipart Upload to S3 with mongodb-stitch-browser-sdk HELP!

[Pablo Cid]

Hi there, someone have tried to upload a big file with stitch? I use this syntaxis for upload files.

import { AwsServiceClient } from 'mongodb-stitch-browser-services-aws';

import { AwsRequest } from 'mongodb-stitch-core-services-aws'

public s3PutObject(dataURL: string, Key: string, Bucket: string) {

const ContentType = this.base64MimeType(dataURL);

const Body = {

$binary: {

base64: dataURL.split(',')[1],

subType: '00'

}

};

const aws = this.client.getServiceClient(AwsServiceClient.factory, "AWServices");

const args = { ACL: 'public-read', Bucket, ContentType, Key, Body };

const request = new AwsRequest.Builder()

.withService('s3')

.withAction('Upload')

.withRegion('us-east-1')

.withArgs(args)

.build();

return aws.execute(request);

}

And works OK for small files.  Someone has tried with this syntaxis to upload big files ???

const request = new AwsRequest.Builder()

.withService('s3')

.withAction('Upload') || .withAction('CreateMultipartUpload')

.withRegion('us-east-1')

.withArgs(args)

.build();

Doesn't work for my. Any suggestion?

Hi Pablo – 

For larger objects, you will need to use AWS' signPolicy() – let me know if you have any questions about this.  

Thanks,

Drew

Hi Drew, let me understand. That function gives me the credentials I need, for example, to connect in the browser with a post request or via aws browser sdk ?
