Fetching calendar items not implemented?

[AlexSugak]

Hello,

I am trying to fetch calendar appointments using FindAppointments (or FindItems) method.
It looks like CalendarView has no implementations for required xml serialization methods yet, so this doesn't work.

Is there another way to search for meetings by date range?
If not, could you please give a hint on proper implementation of CalendarView's required methods (I am new to TypeScript and EWS)?

let me work on this later this week. probably over weekend.

if you just want availability, you can try GetUserAvailability of ExchangeService object.

I have published a release on GitHub (not npm) https://github.com/gautamsi/ews-javascript-api/releases/tag/test-0.2.3-pre

Get latest pre-release and you can install tgz file in npm.

let me know if this helps. Have only tested by running ExchangeService.FindAppointments, not tried loading appointment body, should work though.

Thank you!

Having troubles making it work in browser though.
I see that XHR API is hardcoded to WinJS.xhr right now.
Does this mean that ews api only supports node and browser is not supported?

Will try running from node.

I can give you build for browser, it is not going to help. Exchange EWS does not support HTTP OPTIONS verb, this means browser xhr is going to fail due to pre call.

only way you can test is to run Google Chrome with unsafe (CORS disabled chromium-browser --disable-web-security. You can not deploy it anywhere.

you can sure swap out WinJS.XHR with your own library, just create a shim module with xhr(xhroptions) method returning a Promise. An example on how to create custom XHR.

XHRFactory_WinJS.ts file can also give you information on how to implement simpler shim.

Aha, I see.
Made it work under node. Had to use HTLM from your gist.
Thanks a lot!

Hi, I am trying to do the same thing, using the npm module, and the tar file mentioned above. I have tried both ExchangeService.FindAppointments and the CalendarFolder. Neither works for me. I really could use a hint. I apologize, I am new to EWS. Note, my Exchange server is 2010.

Here is my test script:

var ews = require('ews-javascript-api');
var exch = new ews.ExchangeService(ews.ExchangeVersion.Exchange2010);
exch.Credentials = new ews.ExchangeCredentials("email", "pwd");
exch.Url = new ews.Uri("https://host/ews/Exchange.asmx");
var cv = new ews.CalendarView();
cv.StartDate = new Date("11/14/16");
cv.EndDate = new Date("11/25/16");
exch.FindAppointments(ews.WellKnownFolderName.Calendar, cv).then(function (appts) {
    appts.each(function(appt){console.log(appt);})
});

Here is the version that binds to CalendarFolder:

ews.CalendarFolder.Bind(exch, id).then(function (service) {
    service.FindAppointments(cv).then(function (appts) {appts.each(function(appt){console.log(appt);})});
});

Never mind, I found one answer here:

#68

@AlexSugak see #190 if you want browser based script, still have to use webpack like optimizer. CORS is still the issue. but you can run in Electron/Nwjs renderer process (webview)
