Today's task is to:
- build a single page application with vue.js and TypeScript
- enable authentication and authorization through organizational accounts using adal.js
- get some data from SharePoint site using PnP.js library
As usual, the full code is available here at GitHub.
Let's get started! More...
- Classic pages you said?
- Yes! You read it right. MS Graph API from classic SharePoint page. However please read it first:
That’s not an official or recommended way. That’s just a proof of concept, which uses some tenant features introduced with SPFx 1.6. That’s something I decided to try out when SPFx 1.6 was out. Use it on your own risk.
When to use it? On classic pages if you don’t have an option to execute SPFx code.
So what if you want to call some MS Graph APIs from your classic SharePoint page? No problem then.
Before doing actual coding, we should check that we meet all prerequisites:
- You have SPFx 1.6 features, which work without issues in your tenant. You can test it by creating a simple SPFx web part, which uses MS Graph. Upload it to the app catalog, approve the request to MS Graph and see it actually returns MS Graph data
If above works, you have everything needed for our experiments. More...
SPFx 1.6 was released recently and a lot of new and interesting features were introduced. AadTokenProvider, AadHttpClient, MSGraphClient went to GA, which are my favorite features. One of the common thing in SPFx development is accessing other resources, protected with Azure AD. For example you might have your LOB API with Azure AD protection and you want to consume that API from SPFx web part (extension). Before SPFx 1.6 it was a bit challenging, because you have to deal with cookies attached to your asynchronous http request or with custom “patched” adal.js implementation. SPFx 1.6 features mentioned earlier drastically simplify the task to access Azure AD protected resources. Now you can access Azure AD APIs (including Microsoft APIs like MS Graph) from SPFx with ease!
I’m pretty sure you know about PnPjs library. It has a lot of cool features, among them a fluent interface to SharePoint and Graph API. WIth SPFx 1.6 release you can use PnPjs as your Graph client without hassle. Read further to find out how. More...
Consuming third party or your own Azure AD protected API from SPFx code is a very common need. I wrote a blog post series on that topic, the first one you can find here. All solutions I covered have their own pros and cons, however the less painful and recommended solution is AadHttpClient (available in SPFx 1.6 and onwards). AadHttpClient approach has less issues and works really good. If you are curious about how it actually works, read the rest of the post. In this post I dive into AadHttpClient architecture, libraries and technologies used, think about security issues and try to bypass (spoiler: successfully) webApiPermissionRequests restrictions in SPFx web parts.

Call Azure AD secured API from your SPFx code series:
- Call Azure AD secured API from your SPFx code. Story #1: Azure Functions with cookie authentication (xhr "with credentials")
- Call Azure AD secured API from your SPFx code. Story #1.1: Azure Web App with ASP.NET Core 2.x and cookie authentication (xhr "with credentials")
- Call Azure AD secured API from your SPFx code. Story #2: Web app (or Azure Function) and SPFx with adal.js <—you are here
- Call Azure AD secured API from your SPFx code. Story #3: Web app (or Azure Function) and SPFx with AadHttpClient
It’s possible to call your remote Azure AD secured API with help of popular adal.js library. This approach has a number of issues (read in the end of the post). Almost all issues come from a fact, that adal.js works well in case of SPA and doesn’t play nicely in SPFx world. To make it work with SPFx, you should “patch” it. Even in this case there are some caveats. That’s why for now recommended approach is using AadHttpClient, however for the sake of completeness I wrote a post on adal.js as well. By the way, AadHttpClient is still in preview (as of now, check the actual state at docs.microsoft.com).

In today’s post we need to perform below steps:
- Add new app registration in Azure AD
- Create Azure AD secured API (Web App with custom jwt bearer authentication or Azure Function with EasyAuth aka App Service Authentication, I will cover both) and enable CORS
- Patch adal.js library to work with SPFx
- Create SPFx web part, which uses adal.js and calls remote Azure AD protected API
