I have just started using the NodeJs and curious to know if NodeJS can be used to open the system apps. I an aware that this can be achieved using Python and Java.
Please assist.

Question Background
We are building Chrome Extension. and we need to get the python code in the process.
What i know
I know that python code can be imported using Node JS.
Node JS is used to create servers
Chrome extension is not building server, but making programs(maybe client?)
is it right?
Question
To achieve our goal
Do We need to create server with node js and communicate with chrome extension(using socket.io)?
Is there another way to apply node js in chrome extension?
Is there another way to get the python code into the extension?
Your Chromium web extension code necessarily must be pure client-side Javascript structured to run in the browser's extension environment. There's no support for nodejs or python in that environment; it's very constrained. Because cybercreeps.
You can use XmlHttpRequest or fetch operations in your extension code to access web services. Your extension manifest will need to grant permission to access your server.
You can meet your requirement by building and hosting a server for your extension to use. You can use nodejs and a framework like express and/or socket.io, or you can use python, python-socketio, and a framework like Flask or Django. If you build your server with python, it probably will perform better than a nodejs serves that spawns child processes to run python. It will definitely be easier to install, debug and maintain.
I am trying to implement remote desktop server using libvnc, I have downloaded the libvnc and build the library and able to run sample code. And in the example code I can see the function rfbGetScreen http://libvnc.github.io/doc/html/libvncserver_doc.html which display plain background not the desktop. Does that mean I have to find some other library to get desktop and share using vnc, or vnc has some inbuilt function to do this.
it does seem so. You need to put into rfbScreenInfoPtr::framebuffer screenshots. I've never saw any inbuilt functions yet. May be I've poorly searched.
Try SDL2. May be it will help.
I estimate possibility to write Report Desktop Application using React NodeGUI. There is some questions what I need to find answer before starting to develop by NodeGUI. Could you help me to figure out.
What way is to load program extension dynamicaly in React NodeGUI. For example: If I want to change business logic and visualization of my program without compile code. Is it possible?
What way is to load program extension dynamicaly in React NodeGUI. For example: If I want to change business logic and visualization of program adding some program module code of other developers. How way is it possible to do?
What way is to work with XML files in React NodeGui?
Is there possibility to run other program code written by C/C++ or other languages? What restriction of running non-native JS modules?
What way is to connect to SQL or NoSQL DB (PostgreSQL, Oracle, Mongo and etc)?
What are reasons yet to write or not write Desktop Applications by React NodeGUI?
React NodeGui is just another npm module that you would install in a nodejs program. It is a pure javascript library. It depends on NodeGui which is another regular npm module. NodeGui contains C++ code which acts as a nodejs addon. But for all purposes think of nodegui and react nodegui as regular npm modules. An app built with these libraries is a regular nodejs app.

All business logic is written in javascript so any change in those would follow the same flow of how you would in a nodejs app.
What way is to load program extension dynamicaly in React NodeGUI. For example: If I want to change business logic and visualization of program adding some program module code of other developers. How way is it possible to do?
Yes you can use all npm modules available in npm that works with nodejs.
What way is to work with XML files in React NodeGui?
You can find a lot of npm modules you can use to parse and work with xml files in the npm registry.
Is there possibility to run other program code written by C/C++ or other languages? What restriction of running non-native JS modules?
Yes it is possible to run non js code by building them as NodeJs addons.
What way is to connect to SQL or NoSQL DB (PostgreSQL, Oracle, Mongo and etc)?
You have a lot of modules available in the npm registry for these which work with NodeJs.
What are reasons yet to write or not write Desktop Applications by React NodeGUI?
Reasons to use:
- NodeGui apps are native apps so they get all the benefits of native apps. They are snappy, they are accessible and run with low memory and cpu usage.
Reasons not to use:
Its under development so is only recommended for hobby projects as of Dec 2019.
PS: I am the author of the library
My question pertains to distributing a python application the proper way. i have done research, but the answers appear to be vague and usually instruct the user to upload projects to the python package index. I simply want to make sure i research the proper methods instead of steering in the wrong direction.
I have been writing a stock analysis application with stored text files, and a dozen or so python scripts that interact with each other. Outside computers are to communicate with my servers through a random port (not the internet ports). all the imports work properly and the communication works properly, but i have no clue how to approach the distribution/setup or the GUI.
As an application with dozens of python scripts, should i write each script as an executable via pyInstaller, or should i add a python environment to the application to install python on all the user systems?
I need to add 'README', and 'LICENSE' to the application. What is the point of set up? is that a resource so python knows what is going on or does it actually setup the application? Does it need a URL, and what is the point of using the URL? Do i need anything else for the setup tools?
How do i package the entire application to download on user systems? I want the software to be uploaded via a URL link or from a USB. Do i have to make a tar file? i can do it automatically by writing my own python setup script, but i believe python has an easier way. Do i put a function in the setup to send an executable file to the desktop as a controller so the users don't open all the folders? How do i install from a link on a website?
For a graphical interface for the users on python applications, do most programmers use tkinter, or python integration into HTML, CSS? I do not want this application to be live in a website, but rather as a desktop application. Do i need to use a framework, such as django, to implement python into my html code?
I apologize if this is all unorganized. Ive always coded my own programs and never distributed or put a GUI on any of the scripts, so i just want to make sure i approach the task the right way.
I am using win32ole to access COM-OLE (automation) bindings inside a windows PC such as excel, word etc.
Now what I want is to implement a COM-OLE server using nodejs. I can't seem to find any nodejs module that supports these.
In the end, I only need to expose COM-OLE objects/interfaces to any applications running inside the PC so that they can access my application.
Thanks and BTW, I am using Electron.js.
Since win32ole only appears to operate as a client, you're stuck either:
Implementing your own COM server in C++ (nan helps with the node glue)
Writing a COM server in .NET and using edge for the node glue.
