We use TypeScript's union types to define the different download states. Additionally, a download has a number indicating the download progress from 1 to Once a download is done, it will contain a Blob as its content - until then this property is not available, therefore null.

Now we want to abstract from specific HTTP events to our newly defined data structure. 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.
