memory-stream | js streams implementation for buffered memory | Runtime Evironment library

I am trying to learn how to use with Microsoft's Open XML SDK. I followed their steps on how to create a Word document using a FileStream and it worked perfectly. Now I want to create a Word document but only in memory, and wait for the user to specify whether they would like to save the file or not.

This document by Microsoft says how to deal with in-memory documents using MemoryStream, however, the document is first loaded from an existing file and "dumped" into a MemorySteam. What I want is to create a document entirely in memory (not based on a file in a drive). What I thought would achieve that was this code:

What is the correct way to read and process a remote zipped xml file in C#?

Here is what I try:

I've located the end of a local file header in download stream of a large zip file that

• specifies deflate compression with
• bit 3 set indicating the length of the compressed data follows the compressed data

and would like to now inflate that data using Node zlib but I cannot figure out how to feed data into zlib and receive feedback telling me when the deflate stream has self terminated.

Does Node's zlib library support consuming chunks of deflate data and returning a result letting the caller know when the deflate stream has ended?

Or is this an insane thing to do because it would imply I'm inflating on the UI thread and what I should really do is save the downloaded file and once downloaded use an NPM package? Hm.. well.. either the network is faster than inflation in which case streaming inflation would slow the network (bummer) or the network is slower than streaming inflation so why deflate while streaming (which I can't figure out how to do anyway) when I could simply saving to disk and reload-deflate while I'm sitting around waiting for the network..

Still, for my edification, I'd still like to know if Node supports streaming inflation.

I've set up an Azure Blob Storage to upload/download file.

I'm trying to get images saved in MySQL database as BLOB images into a picture box in my Windows application.

This is my code.

I am using below code for reading the base64 input string:

So I am using ExcelJS to create an Excel file. Currently I am saving the file to disk. The data I am adding to the file is coming in from an API call.
