Download File From Azure Storage Angular
Gwen Simon
I'd like to be able to send it directly to azure storage blob from angular using this library. I've been able to send it to my nodejs backend no problem, but it's been challenging for me to send it directly to blob storage instead. Can anyone provide a working example of how to do this? I appreciate any help!
Alternatively, you can instantiate a BlobServiceClient using the fromConnectionString() static method with the full connection string as the argument. (The connection string can be obtained from the azure portal.) [ONLY AVAILABLE IN NODE.JS RUNTIME]
Alternatively, you instantiate a BlobServiceClient with a StorageSharedKeyCredential by passing account-name and account-key as arguments. (The account-name and account-key can be obtained from the azure portal.)[ONLY AVAILABLE IN NODE.JS RUNTIME]

So we need to go back to our hosting provider and update the cname record, changing from the storage account endpoint to the one listed on this form. This, again, will take a little while to propagate.
Open Azure Storage Explorer, navigate to your storage account and create a blob container by right-clicking on Blob Containers. In my case, I've created one called angular. Now drop the files you created in the first step here.

I've started on a new project with ASP.NET Core and Angular from template version 7.2.3.The Angular application will be deployed to a Azure Storage Static site according to -core-angular/latest/Step-by-step-publish-to-azure-angular-staticsite. Therefore I had to enable hash location strategy to get it to work, by setting useHash: true in RouterModule.forRoot(routes). If that is the case you should add that to the documentation. If not, am I missing something here?
When building cloud-hosted applications, it's not ideal to have users uploading files and photos to the application's directories. Instead users should be uploading to other cloud storage locations like Azure Blob storage. This arrangement keeps our application's files separate from user content, offloads storage to a cheaper medium, and provides a solid infrastructure for fetching the files from storage. With Angular, Azure and ASP.NET Core this is a task that requires very little code with very big benefits.
After the photos container is created, we'll need to navigate back to the main blade menu of the storage account. On this menu, under settings, we'll find the Access keys for the storage account. From the Access keys menu a connection string can be created that will allow us to access our storage from an API.
Modify the serviceUrl property of the PDF viewer component with the accurate URL of your web service project, replacing :44396/pdfviewer with the actual URL of your server. Set the documentPath property of the PDF viewer component to the desired name of the PDF file you wish to load from Azure Blob Storage. Ensure that you correctly pass the document name from the files available in your azure contanier to the documentPath property.
We have an Angular application, a storage account to hold our application files, and now we need to configure the Function Proxies to serve our content. The image below shows configuring the initial proxy. This is for the root url and will point to our index.html file from our Angular application.
John Papa's blog post provides some great detail, but his post and build process uses node and an App Service to provide the Angular application. We can certainly leverage the initial steps from John's post, including the VSTS Tasks to install the Angular CLI, install the project, and build the angular application. However, we want to clean the storage containers and then copy the updated content to the containers once Angular builds.
If your app uses Angular routing you still have work to do. Navigating to a route starting from the root of the app causes no issues, because the Angular router interprets the URL and routes to that page. But entering a deep link in the browser address bar or refreshing the page while on a route does. An example of a deep link is something like -of-heroes.azurewebsites.net/detail/14. The browser will make a direct request to the server for that URL, bypassing the Angular router, and return a 404.
Copy the .env.example file to .env in the root of the repository. Add the values above from the Azure storage account and Active Directory application. You can leave AZURE_CACHE_CONTROL equal to "no-cache, no-store, must-revalidate" for now. Eventually we'll want to set this to ensure the CDN caches our content, but for debugging, it's easier to skip caching.
By default, blobs have a seven-day time-to-live (TTL) at the CDN edge node. After that time elapses, the blob is refreshed from the storage account to the edge node. Blobs that are shared via CDN must support anonymous access.
We can generate a Shared Access Signature (SAS) URL in Azure to provide access to this video file directly from the blob storage. SAS makes the URL publicly accessible, and you can also enforce other access restrictions on it. The URL can then be used directly on your website or app to load the video
We have to then attach this external storage to a URL endpoint in our dashboard, making it accessible via ImageKit. ImageKit does not copy any content from your blob storage. Instead, the above integration provides access to the original file when you request it via a URL.
ImageKit is a real-time media optimization, transformation, and management product that simplifies streaming optimized videos directly from your Blob storage. Once the storage is attached, we can use the URL-based real-time video API to optimize videos automatically, convert them to the right format, adapt them to web and mobile, and build adaptive bitrate streaming using DASH and HLS protocols.
We are going to go over the most simple scenario, in which the web app authenticates right away on load.
But if you need to check other scenarios, the @azure/msal-angular package page is your place to go.
