Is it possible to access EWS managed API from javascript - javascript

I want to create a web application, using html and JS, and I will be accessing EWS managed API. So can we access EWS API via javascript or any other language?
If yes how to do so?

If anyone still looking for JavaScript version, I am author of ews-javascript-api at https://github.com/gautamsi/ews-javascript-api, this is functional and have many operations supported. mostly most common calls. open issue at GitHub for anything not implemented I usually take next weekend to publish that feature in npm if not complex.
Published as npm ews-javascript-api
Due to Exchange CAS server CORS limitation (HTTP OPTIONS verb not implemented) you can not use it in browser. Node.js works fine. You can also use it in Electron (Atom Shell) or in NW.JS (Node-WebKit)
Support Office 365 and on-prem Exchange, all version supported by ews-managed-api (official repo).
Supported Authentication mechanism:
Basic (provide HTTPS url when calling)
Kerberos (with provided sample link in readme)
Cookies with ISA/TMG (with provided sample link in readme)

The EWS Managed API is a .NET wrapper around the EWS API (SOAP and POX Web Services).
If you're using a .NET language such as C# then you should use the EWS Managed API on the server-side and create your own JSON services (I recommend ASP.NET Web API) for your client-side JavaScript to call.
If you're only using JavaScript, you may be able to use node-soap to call the EWS SOAP services.

How to add a REST API to the Modern Web Dev Server?

I'm using the dev-server of Modern Web to build client side code.
Now I want to add a small backend with a REST API, but I can't find any information of how to add a backend with a REST API to this server.
Any hints on where to start?
You could write a plugin for it but I wouldn't recommend it.
It's a development server designed for testing client-side code.
It isn't designed to be a production server, and if you are going to write a REST API then you will, presumably, want it to be usable in a production environment.
Build your API with a tool designed for it (such as Express.js or Spring Boot) and use CORS to make it accessible to the server you use for client-side development.

IBM MobileFirst 8.0 integrate with Integration Bus

For our mobile apps we implemented our adapters using JavaScript where procedures simply do MFP.Server.invokeHTTP. But now we need somehow integrate with IBM Integration Bus (IIB), and I can't find any information how to do it.
I have only limited knowledge how Integration Bus works and why it needs.
Is it possible to do it with JavaScript or it possible only in Java (also all examples, that I found - it simple how to create services for IIB)?
Should we configure MobileFirst Server (via Operation Console) to connect to IIB or we need import additional packages?
If I get it correct you are already calling web services via HTTP .
IIB provides you web services like REST SOAP... in your case you can simply ask your team (IIB ) to build services as REST and expose them... from you mobile server you can simply call them like any other service... like you can provide the IIB rest service url in you http method and get resoonse back.

Accessing Bloomberg API from client's browser in javascript

Is it possible to access blpapi from javascript running in the client's browser?
I wish to access bloomberg's API from javascript running in the client's browser, in the assumption that the client has an open bloomberg session and therefore bbcomm is running.
Conceptually, this would be the same as accessing the blpapi on the client side from python.
However, all existing solutions I found in js appear to be server-side:
blpapi-node (node-based)
blpapi-httm (creates a server where to post http request)
blpapi-react (cannot make this module work)
Now you can access Bloomberg data natively in JavaScript via Web AppPortal. This allows you to write web based applications that run inside LP Components.
To learn more about Web AppPortal, go to MYAP 5
To download the SDK, please type SDK -> select SDK -> AppPortal Web SDK -> click Install.
This is obsolete, see Mourad Barakat's answer above
Conversation with Bloomberg Support confirms this is not possible**
BB say they don't support javascript access, and that one solution is to use their Server API to use the authentication of the client (who has a bb terminal open) to query data and return it to the client
An alternative hack
An alternative hack is to create an executable mini-server that the client downloads and launches, and that offers an http interface to get data to the webapp.
For example, this could be done in Flask in Python, and in fact it has already been done by blpapi-web (excluding the executable part, for which you can use PyInstaller and py2exe for Windows and py2app for Mac)

how can i access mail from a microsoft exchange server using javascript?

I am trying to build a desktop app using electron that retrieves mail from a specific mailbox (microsoft exchange server), now, i have looked around and read that mailbox connection should be done server side (the question was made by a guy building a web based app that is a little bit similar to what i want to do), but, since i am not really deploying a node js server but rather using electron, which, as far as i understand is like a desktop app version of node, im not sure on which approach to take. Should i use an api? does microsoft has any interface for this? or should i use a third party integration for it?
It looks like the Exchange Web Services API is only provided as a CLR assembly, so if you wanted to use it you'd need to:
write a C# console app that you then spawn from your Electron app
(and communicate via stdin/stdout), or
use the EWS API in your Electron app via Edge.js
Alternatively, you could probably just directly communicate with the exchange server using SOAP messages, but that could be a bit tedious to implement.

Using Gigya API with node.js

For one of my projects I'd like to try out Gigya as my social network connection provider and am writing my app using Node.js. Has anyone done this?
Gigya provides a JavaScript API that is intended to be used on the client.
http://developers.gigya.com/020_Client_API
It should be possible to adapt that for server side use.
Gigya's client side javascript is intended to be run in the browser as much as possible, since they perform 2 part authentication using cookies set by their domains. You can try to port it to run server side, but none of the public methods will work as advertised.
I've written a wrapper for their REST API using their proprietary authentication that I've been using in a work project for a few weeks: https://github.com/jproulx/Gigya-Node-SDK -- note that not everything has been tested thoroughly as I've only needed to use a subset of the socialize services on the server side. It should serve as a good jumping off point to bootstrap something for your needs.
Gigya does not yet have an official Node SDK. However, I've written an SDK that implements the entire service.
In addition to the standard APIs, it contains special support for streaming data from Accounts & DS.
Git: https://github.com/scotthovestadt/node-gigya
Install with "npm install gigya".
