In VS2013, intelliSense in a NodeJS App in a *.js file works like a charm. I was wondering if there is also intelliSense supported in a TypeScript file for several NodeJS-Modules? How can I enable intelliSense for NodeJS in a TypeScript file?

DefinitelyTyped is the place to look for typescript definition files:
https://github.com/borisyankov/DefinitelyTyped/tree/master/node
You can use your favorite package manager to get it and all of the DefinitelyTyped deffinitions are available in NuGet.
There are a quite a few specific NPM modules on there too, but some you will have to define yourself.
In VS2013 when you add a deffinition file (*.d.ts) then it will be available from the IntelliSense.

I can't initialize the npm package in Notepad++. I don't know how to do it, because in every video the Youtubers initialize them with the program's terminal, but I think Notepad++ doesn't have a terminal or if it does I can't find it. Can anyone help me please, cause I can't finish my Login system if I don't have that package? Or should I use another program for example Visual Studio? What's the best HTML development program?
Open Terminal or Command Prompt if you are using windows.
go to the folder where your project is using cd command.
Install npm's you need.
The terminal in any code editor is same as operating system terminal.
I will suggest to use VS Code for learning as most tutorials will be using that.

I have created React apps.when I try to build react project using "npm run build" command from terminal,it takes more than 15 minutes to build project.Can any one advise what is the actual problem of this ???
It creates build for production, so it invoke some optimizations
If you want build your app faster you can build with development enviroment without optimizations
For this you can change mode parameter on mode: 'development' in your webpack config

I got a components library that will be published to npm to be consumed by a razzle app. My main question that I want opinions on best practices is, should the packages be built with cjs or esm, and what is the downsides of each?
Am I fine with only building to cjs?
ESM
Tree shaking
More understandable in code.
Allows lazy loading of the component
Gives more easily the ability to import a certain part of the code.
cjs
Cross build
Supported on more environments
If its no problem for you use both. One for every environment. CJS would work on most environments.
If your target is only react or other frontends es6 gives you all the advantages above. But if you want you component to be usable in javascript webpack like legacy apps you should use cjs, also for the backend.

I know dist folder is used for production, distribution and what it should contain.
What i want to know is, when is the best time to use it? in what kind of work environment/project requirement i should use dist folder? like Heroku, what are the other platforms where i can deploy an app without dist and the platforms where i can't deploy without it (if there is any)?
I'm new to this, if someone can clearify the process would be very much helpful.
The dist folder is for production website it's not necessary to have it. It will contain for example your image, css, script, vendor folder ready for production (minified and concatenated).
You can check on google for this. Type "how to deploy a production React app to Heroku" for example.

Maybe I am doing it wrong. I want to do changes in node_modules folder. Now when I run npm run watch or npm run dev it doesn't get reflected in UI.
Any idea what is wrong?
Try editing from the /dist folder of the library you are trying to edit. Your changes will not reflect if you edit from the source and not from the output bundles.
Note: If you are just logging a result (via console.log) that is fine, but as much as possible, do not edit from the node_modules folder.
