In web applications we added new block that let you upload files to any S3-compatble storage directly from web applications bypassing backend.
For file upload you need to use S3 pre-signed URL and correctly set CORS in your bucket. As in all new upload file blocks we supply upload progress tracking via dedicated Flow-Out connector onProgress.
Please note, that standard AWS CLI can’t create pre-signed links to upload files and you have to create them via AWS S3 API/SDK. We have plans to update AWS S3 API module in backend apps to include blocks for pre-signed links generation.
