file copy on save or upload in vs code - visual-studio-code

Question

I work frequently providing custom java script solutions to SharePoint. The annoying part at the moment is that either I need to setup a watcher to check file changes and overwrite it in the directory where the files will be in SharePoint or I just move then manually. Is there anyway we can setup something with a config file, like it is with the watch tsc compiler.
All I want is, for example to run robocopy when I save a file.
Or even just overwrite the same file specified location, preferable not dependent on extensions.
Thank you all.

For those wondering. I was able to achieve it with the simplest way I can think of: by using fs.watch or node-watch package.
created a js file with the code below to watch file changes in the src dir and act depending on the event.
watch.js:
//if you are using fs:
//var fs = require('fs');
//
var watch = require('node-watch');
//fs.watch if using the node fs.
watch('./src/',{recursive: true}, async function(evt, name) {
if (evt == 'remove') {
// on delete runs rest call to delete the file
}
if (evt == 'update') {
// on create or modify runs rest to upload the file
}
}
with that you can either run the cmd "node watch.js"
or create a task to run on folderopen.
./.vs_code/tasks.json
{
"type": "npm",
"script": "watch",
"label": "wathever label you want",
"isBackground": true,
"runOptions": {
"runOn": "folderOpen"
}
}
package.json:
"scripts": {
"watch": "node watch.js"
}
For the task to run on folderopen you also need to allow it in the folder. you can search on the command pallete (ctrl+shift+p), "Tasks:Manage Automatic Tasks in Folder" to enable it.
