unzipper | Small class to extract + compress .zip , .gz , .rar | Compression library

I have a function which unzip a file form the directory. It's working fine

index.js

I have successfully integrated unzipper inside my Lambda. Here's the code:

I have this index.js which uses this unzipper module

I have a function in my Lambda named my-s3-function. I need to add this dependency to my Lambda Node.JS. I have followed this part to update the script with dependency included (though, I didn't follow the step wherein I need to zip the folder using zip -r function.zip . but instead I zip the folder by right-clicking it on my PC).

The zip file's structured like this inside:

so I have 2 files, a zipped file with all my files/folders for a game and a unzipper.bat file that puts everything in the correct place to work.

I decided to use IExpress to make an installer for my game, and there was an option for running a file on installation, so i put setup.bat there thinking that it would run when all the files were installed, but it didnt do that.

how can I make it so that it runs setup.bat ones all the files have been installed?

edit: this i my current SED file

I can't find what I am doing wrong here. I'm trying to unzip the files then go though them creating a new HTML in each folder and also renaming the image files.

I tested it and the script is waiting to unzip the files before go though them, but I'm always getting the following error:

Below is my method which is calling two delegate function which in turn return two keys partition and Row key. the methods are same for generating partition and Row key and only difference is which string from list returned to be taken as row key and partition key. I would like to know if there is way I can optimize my below method and use one delegate function instead of two.How do i do it?( if possible someone can show me).

I need help in making my method asynchronous:

This is the method, which works fine now, but if I remove GetAwaiter().GetResult() , I don't get the values and I am told that GetAwaiter().GetResult() is not a good practice. So I would like to know, how I am going to change it to make it asynchronous. If i write internal async Task , I get error from my other methods from where its being called as return type is not correct. How do I fix it?

I'm working on upload task with nodeJS (express), the goal is to upload a zip file contain some mp4 files, I want to extract the zip content on a directory that take the user name (req.user ) if not exist, or if it exist I do not need to recreate it just put the zip content inside.

can some explain how to do it technically, I finished the upload and the extract process but need to understand deeply how to do this task, I have thousand of user connected on my app.
