I'm working on a chrome extension and I need to get a schedule data from outside of the extension to let the admin broadcast the schedule to the extension users. I wanted to use hapi.js but I can't afford to buy any private server. I did find free website hosting. I thought I would do a minimal website with just a login system and some pages containing the data I would want and make some get request on the extension and extract the schedule on the extension.
Is it okay like a replacement plane for the API?
For almost the same purpose I was using WordPress website with json api plugin. (https://wordpress.org/plugins/json-api/) It is super easy to install and later you can simply run fetch requests inside of your application or extension.

I'm trying to write a web application which needs to exchange messages with a local Smart Card.
Currently I'm trying to use WebUSB API to connect the Chrome with the smart card reader, but I'm struggling to use the PC/SC specification.
In my researches I found this two topics:
Architectures to access Smart Card from a generic browser? Or: How to bridge the gap from browser to PC/SC stack?
How to send APDU to PCSC reader from web broswer using javascript
Although they deal with the same subject, they have no connection examples.
If anyone has any tips or example of connection I would be grateful.

I'm starting a project that will use a search bar to hit a web api and return the results. There will be no writing to the web api.
My biggest struggle when creating a new project is how it should be laid out. I never know when i should create a DAO, do it all via javascript, put it in a controller, etc.
For developing something like a search engine or any web application. You would need following:
A frontend, which is your application's GUI in browser of user or mobile application.
A backend logic, this could be in any server side scripting language, in your case you would be writing server code in .net
Now, your backend must expose a search api, Eg. If I send a HTTP GET with a variable q, it should return search results matching the query.
Your frontend must have input-box and a button for allowing users to send this request.
This answer isn't complete, just a vague overview of how this problem can be approached, also this isn't the only solution.

If we are running two different node instance one of each purpose( webservice engine/data engine and webservice consumer) will it be good or keeping both the purpose in same application will be better ?
Yes it is.
One project is your API, the second project is the access to your API by web.
Maybe in the future you might need a mobile app to connect with the API or maybe the webapp technology becomes obsolete and you might need to replace it for another modern technology, so that you don't have to change your API.

how can I communicate javascript with C++, run some commands, get active processes, but I didn't find any information on the web.
What I saw is the following links but none helps me:
http://comunidad.aisoy.es/api/Communication.html
http://www.mosync.com/docs/sdk/js/guides/wormhole/extending-javascript-with-cpp/index.html
http://www.codeguru.com/cpp/i-n/ieprogram/article.php/c4399/JavaScript-Calls-from-C.htm
Based on your tiny requirements description, here's a brief overview:
Run your C++ code as a stripped down version of http server, OR better write a C++ apache module. Make your javascript to make AJAX request to the exposed URL by the C++ http server, return the response in JSON/XML.
Just the standard way for your UI (javascript) to speak to the backend (C++)
