postman apps into nodejs, how it works? - node.js

I am still new to learning backend, I think I skipped too quick and I'm trying to push or simple post or call ? or request ? to localhost:3333/api/notifybut using or implement in node.js or cli ? or just use coding, not using application like this below picture (using postman-apps), so everytime i run the program, it will trigger and push to that localhost rather than using postman-apps. also so i know how it works because this postman is a simulation right?
basicly I still lack of knowledge about this so I don't really know what is this postman, is this like a server then does get.req ? or something, I was searching a lot but also I really have no idea. I will be happy if you show me some sources too for me to learn this.
because this postman apps only input http://localhost:3333... and then somehow there are some JSON from the apps itself created ? anyway just answer my very first question, probably i will understand later, thankyou.

nevermind, I learnt it, it was REST-API things

Is there a way to deploy my app on a hosted platform?

Dear Stackoverflow people,
I am facing the following problem:
For an internship in a company I have created a leaflet map with several custom features such as custom popups, markerstyle etc. The thing is, in the end they are supposed to manage the whole thing. Since they don´t know anything about code they asked for the easiest possible way for them to add data to the map.
So I came across the serverside tutorial by CodingTrain using Node.js and thought its perfect for me. Now I created basically a webform that takes up all information, converts it into a geoJSON feature, stores it in a database and sends it to the map to be displayed, great easy GUI to add new features...
Now comes the bummer which I didnt know would be a problem: The website is on a hosted service called Bitrix. I uploaded my project and it does not recognize the routes and cant write to the database or anything. I actually dont know whether I can run node on this platform?
I had the idea to launch the whole thing on a Service like Heroku or Glitch and just take the map from there and include it into the other website via an Iframe or something like that. Do you guys think thats feasible? Are there any other better ways?
Sorry for my obvious cluelessness but I´m completely new to serverside programming and thought I´d found an easy way out... I am grateful for any kind of suggestions or help!

Getting skype status from Javascript/Node

So I've been looking around for answers but haven't been able to find any up to date solutions to my problem. So my use case is pretty simple, I want to be able to check the online status of a list of users at my organisation using Skype for Business. Opening chats with them is simple enough, but actually getting the online status has shown to be a challenge.
I've been looking into the SDK but it seems a bit over the top for my use case, and I haven't been able to get web ticket authentication working (I'm implementing this in an Electron app). Even if I got that far, would I have to make an account with specifically only the contacts I need added and use that as authentication?
Sorry if this is a stupid question, but it seems like the SDK/API is a bit over my level and I'm missing something. Do I need to add in my own server middleware between the node/electron-app and their API or something similar maybe?
Any help is greatly appreciated.

How does the DocuSign API work?

I am very confused as to how the API of DocuSign works, I tried looking it up here:
https://www.docusign.com/p/RESTAPIGuide/RESTAPIGuide.htm
But that didn't help me much, especially not because I need to implement DocuSign into the open source version of Vtiger.
Does anybody here know a site where I can learn more about DocuSign and how I can combine it with Vtiger open source?
As for what I already tried that is nothing, I first need to make a functional design which is kind of hard to do when you don't even understand the basic API.
I would really appreciate it.
I have never worked with an API before, so this is all new for me.
Have you tried the API overview instead of the reference guide? Check this out:
https://www.docusign.com/developer-center/api-overview
You can also look at the API Recipes to see some starting examples of what you can do in any language. I believe VTiger is written in PHP so you can find the PHP code to copy and paste to get you started.

NodeJS execute flow in background (server side) and grab the html

I am having a website which has many sections and multiple pages in each section.
There is a feature called "Generate PDF" which will traverse through all the sections and pages one by one and grab the HTML from the browser and then generate its PDF. This is working fine as of now.
But this is holding the user from doing anything until the PDF is generated.
I want to have some help on how I can do the same process in background (on server side) ? I have heard from someone that node-curl may help in this but I am not familiar with that.
Can anyone suggest me some ways to proceed further?
If anyone aware about node-curl and just can give hint that it may help me to resolve the issue then also it will be good. I will learn about it and invest my time to get it done.
Or else if someone came across the same kind of problem and have any idea then it will be good.
I am open to use any npm to get it done.
We are also using EmberJs so if any suggestions on that part then also welcomed.
Thank you.
Do you mean you implemented 'Generate PDF' in your client side emberjs code?
If you are running a nodejs based server, you can use node-curl to grab the HTML from intended URL. It is can be risky and you might end up in similar problem of blocking because nodejs runs on single thread. Better you fork a new process to execute 'Generate PDF' logic on separate thread.

Can I use node.js with Objective-J?

I would like to write a web application using node.js and Cappuccino. I want to write the back-end in Objective-J, just like the front-end.
Can I use node.js with Objective-J? What is needed to do this?
beeing a professional Objective-J coder I can say it is definitely possible since Objective-J is fully based on JavaScript. But I also have to say that I never tried it.
I think it would be a good idea to directly start a discussion in the official Objective-J Google Group:
http://groups.google.com/group/objectivej
