ews-javascript-api

Exchange Web Service in JavaScript/TypeScript.

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

• Basic - inbuilt
• NTLM - using XHRApi adapter
• Cookies/FBA Authentication with TMG/ISA - using XHRApi adapter

use SSL for basic authentication
NTLM and Cookies Authentication works with nodejs only

Modules

• commonjs module for NodeJs
• AMD module for browser*

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

Getting Started

install

[sudo] npm install ews-javascript-api

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

//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

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
});
