In today’s post we’ll go through how you can setup an SPA (Single Page Application) to access the data pane of an Azure Storage account. For this I’ll be using NuxtJS (a Vue.js framework) for my boiler plating, and will rely on the its generic Oauth2 authentication library. The awesomeness here is that the bearer tokens will automatically be injected in your API calls (Axios). Though you can use this post as inspiration on how to get things working in another framework too!
Why this post? It has has been on my personal todo list for a while due to many reasons. One of which is to remove the barrier of using Azure Storage in this scenario. I find that it makes a lot of sense in way too many use cases. Though I must admit we’ve failed to reduce the learning curve in this scenario! You suddenly find yourself in flux between the complexities of AAD and the way how Azure Storage handles the presented JWT tokens. That being said, this is actually the only correct (secure) way of talking from an SPA to Azure Storage. DO NOT use storage keys or SAS tokens in your SPA. It’s like leaving your master keys out on the porch of your house. AAD is the correct way, and actually… With an SPA, the only correct authentication flow is actually Implicit Flow.

Probably everyone can relate that they do not want to invest the time in something “as commodity” as authentication when developing. Though on the other hand, the “identity” part is a key part to keeping your application (and thus your organization’s data) secure. So how to find the perfect fit in terms of this balance? Leveraging identity providers is the typical path to take here. Where there are quite a few in a SaaS service model even. From the Microsoft stables, you can find both Azure Active Directory & Azure Active Directory B2C to play an important role in this space.
When looking in this space, the defacto protocol standards here are Oauth2 & OpenID Connect. Where OIDC (OpenID Connect) is actually a layer built on top of Oauth2. Anyhow, where they provide a very good / robust security layer, the flip side of the coin is that (like with any security product) there is a given entry barrier in terms of understanding the complexity it brings (in terms of authentication flows).
