EWS managed API for TypeScript/JavaScript - code ported from OfficeDev/ews-managed-api. availbale for nodejs, browser and mobile devices (cordova).

Pluggable XHRApi adapter to replace client (browser) based XHR call with server brokered call (example coming soon). Example Ruby on rails, PHP or any server side framework where c# or nodejs is not available

Works with Office 365/Exchange Online and on-premises Exchange (2007 - 2016)

Authentication

Modules

All http call is wrapped in promise using WinJS promise.
Code sample from EWS Managed API 2.1. should work with little modificaion to Promise format

Documentation

Getting Started

use

//classic Javascript style
var ews = require('ews-javascript-api');
var exch = new ews.ExchangeService(ExchangeVersion.Exchange2013);
//ES6 TypeScript style
import {ExchangeService, AutodiscoverService, Folder, Item, ExchangeVersion} from "ews-javascript-api";
var exch = new ExchangeService(ExchangeVersion.Exchange2013);

## Autodiscover user settings

javascript
//import ews module
var ews = require('ews-javascript-api');
//create AutodiscoverService object
var autod = new ews.AutodiscoverService(new ews.Uri("https://autodiscover-s.outlook.com/autodiscover/autodiscover.svc"), ews.ExchangeVersion.Exchange2010);
//you can omit url and it will autodiscover the url, version helps throw error on client side for unsupported operations.example - //var autod = new ews.AutodiscoverService(ews.ExchangeVersion.Exchange2010);
//set credential for service
autod.Credentials = new ews.ExchangeCredentials("userName", "password");
//create array to include list of desired settings
var settings = [
ews.UserSettingName.InternalEwsUrl,
ews.UserSettingName.ExternalEwsUrl,
ews.UserSettingName.UserDisplayName,
ews.UserSettingName.UserDN,
ews.UserSettingName.EwsPartnerUrl,
ews.UserSettingName.DocumentSharingLocations,
ews.UserSettingName.MailboxDN,
ews.UserSettingName.ActiveDirectoryServer,
ews.UserSettingName.CasVersion,
ews.UserSettingName.ExternalWebClientUrls,
ews.UserSettingName.ExternalImap4Connections,
ews.UserSettingName.AlternateMailboxes
];
//get the setting
autod.GetUserSettings(["email1@domain.com", "email2@domain.com"], settings)
.then(function (response) {
    //do what you want with user settings    
    var tabcount = 0;
    var tabs = function () { return ews.StringHelper.Repeat("\t", tabcount); };
    console.log(autod.Url.ToString());
	//uncoment next line to see full response from autodiscover, you will need to add var util = require('util');
	//console.log(util.inspect(response, { showHidden: false, depth: null, colors: true }));
    for (var _i = 0, _a = response.Responses; _i < _a.length; _i++) {
        var resp = _a[_i];
        console.log(ews.StringHelper.Format("{0}settings for email: {1}", tabs(), resp.SmtpAddress));
        tabcount++;
        for (var setting in resp.Settings) {
            console.log(ews.StringHelper.Format("{0}{1} = {2}", tabs(), ews.UserSettingName[setting], resp.Settings[setting]));
        }
        tabcount--;
    }
}, function (e) {
    //log errors or do something with errors
});

Example EWS operations

Example of user availability ```javascript var ews = require(‘ews-javascript-api’); //create ExchangeService object var exch = new ews.ExchangeService(ews.ExchangeVersion.Exchange2013); exch.Credentials = new ews.ExchangeCredentials(“userName”, “password”); //set ews endpoint url to use exch.Url = new ews.Uri(“https://outlook.office365.com/Ews/Exchange.asmx”); // you can also use exch.AutodiscoverUrl

var attendee =[ new ews.AttendeeInfo(“email1@domain.com”), new ews.AttendeeInfo(“email2@domain.com”)]; //create timewindow object o request avaiability suggestions for next 48 hours, DateTime and TimeSpan object is created to mimic portion of .net datetime/timespan object using momentjs var timeWindow = new ews.TimeWindow(ews.DateTime.Now, new ews.DateTime(ews.DateTime.Now.TotalMilliSeconds + ews.TimeSpan.FromHours(48).asMilliseconds())); exch.GetUserAvailability(attendee, timeWindow, ews.AvailabilityData.FreeBusyAndSuggestions) .then(function (availabilityResponse) { //do what you want with user availability }, function (errors) { //log errors or do something with errors });

Porting status

Review Core/ExchangeService methods in api document, Any method not marked private oe internal (internal marker is in description of method) is posted and can be used, open issue if it doe snot work

List of ExchangeService methods ported

List of Folder object methods ported

List of Item object methods ported

Use in Cordova

AMD module for require.js to be included in build system, will be published bower module and documentation.
