How to Upload Large Files in Azure Blob in chunks from using Rest API JS?

Question

Hi Team,

I have tried to upload large files from the LWC componet in chunks. But not found any call-back URL for uploading large files up to 4 GB to 10 GB from Rest API.

Can you please provide any links or documents for uploading large files in chunks from Rest API in Azure Blobs?

Thanks

Note: We also recommended to use Azcopy tool to upload files from on-premises or cloud (Use this command-line tool to easily copy data to and blobs from Azure Blobs, Blob Files, and Table storage Storage with optimal performance. ) AzCopy supports concurrency and parallelism, and the ability to resume copy operations when interrupted. It provides high-performance for uploading, downloading larger files. Please consider using this library for larger files.
