Registering the provider in the Injectable metadata also allows Angular to optimize an application by removing the service if it is not used. If you are not using stricter type then your code should be working fine as it is working for Angular First replace the line this.
I am also accepting response as Blob Binary Large Object. You may also specify any value from supporting values, such as, json, blob, arraybuffer, text. You can have a look for more details on response type. I have used three ways for downloading file — two ways for Save as functionality and one way to show the file content on browser itself. The above line create a Blob object with file content in response and expecting the file of JSON type.
The above two lines create a URL that will open the file in browser in new window. The above line shows the file content on browser, so it does not give you save as option.
Generally, we can set the Content-Disposition of blob to attachment to indicate that the user-agent should not display the response, but instead show a Save As dialog with a filename other than the blob name specified. You can refer to Set Blob Properties for more information. Can I set the disposition on initial upload? And the Angular frontend will download the file instead of directly opening it in FireFox browser in my test. There are two ways for doing this without streaming the contents through your web server and both of them involve setting Content-Disposition property on the blob itself.
Is that something I can set across all my blob containers using something like Azure Storage Explorer? What's New. Most popular in JavaScript. Convert a string to an integer in JavaScript Node.

This way our components can be decoupled from the underlying network protocol. Since we're dealing with multiple events coming in over time, a RxJS operator is well suited here - so let's create one!
The first step for this will be the creation of type guards helping us to distinguish different HTTP events. This way we can access event-specific fields in a type-safe way. They both contain the discriminator field type allowing us to easily return a boolean for the type assertion in our guards. The guards can be used with a simple if-statement, however, TypeScript will narrow the event type inside the statement block for us:.
Based on these guards we can now create our custom operator. It'll leverage scan , an operator that allows us to accumulate state for successive values coming through an observable. It takes up to two arguments: First, we provide an accumulator function which will compute the next Download state from the previous one and the current HttpEvent.
Second, we'll pass a seed to scan representing the initial Download state. This seed will represent our download being pending without any progress or content:. Our accumulator will use the previously defined guard to update the Download state over time with information from the HTTP events:. When we encounter a HttpProgressEvent , we calculate the progress based on the number of bytes already loaded and the total bytes.
A download is done when we receive a HttpResponse containing the file contents in its body. When receiving any other events than HttpProgressEvent or HttpResponse , we won't alter the download's state and return it as it is. This way, for example, we can keep the information in the progress property while other events that won't allow us to compute the progress can be ignored for now.
