Some keywords to sum it up would be: ajax, xhr, fetch, stream, pipe, RAM, filesystem API, large download, up to times faster incase website throttles the speed PS more download thread dosen't always mean it downloads faster Wow everyone in this industry has something against proper use of RAM.
Yea, it "stitch" a file together using ajax and filsystem api My code dosen't use http2 And its not chrome only Its blink only wich means chrome and opera.
Opera is a great browser.. I'll give it a look, see if I can stitch something up. Sounds interesting, but how cross-browser is it? Their code is only 80 lines, have you tried plugging it into FileSaver? DannyZB but how cross-browser is it? And also MessageChannel but that is less important I also want to give some credit to muaz-khan for building the Screen Capturing for giving access to the screen as a stream. Streamsaver works with any other lib but are limited to only working in Blink atm.
All other ways are buggy, unstable or unsupported. Doesn't seem like a high priority for them -- let's hope that changes. Choose file system entry will help a lot later where you can save a readableStream. RyanHow mentioned this issue Apr 15, The request will be one simple json.

Adrita Sharma Adrita Sharma I've set the HttpHeader as blob but still the same issue. Your call would then look like this: this. Also, I would suggest using a File object instead of just the Blob , which gives you the flexibility of giving it a filename like so: public downloadFile response: any, fileName?

If you want other formats change the mediatype and file name with right extension. I was facing this same case today, I had to download a pdf file as an attachment the file shouldn't be rendered in the browser, but downloaded instead. To achieve that I discovered I had to get the file in an Angular Blob , and, at the same time, add a Content-Disposition header in the response.
Well, I wrote a piece of code inspired by many of the above answers that should easily work in most scenarios where the server sends a file with a content disposition header, without any third-party installations, except rxjs and angular.
As you can see, it's basically pretty much the average backend call from angular, with two changes. Once the file is fetched from the server, I am in principle, delegating the entire task of saving the file to the helper function, which I keep in a separate file, and import into whichever component I need to. There, no more cryptic GUID filenames! We can use whatever name the server provides, without having to specify it explicitly in the client, or, overwrite the filename provided by the server as in this example.
Also, one can easily, if need be, change the algorithm of extracting the filename from the content-disposition to suit their needs, and everything else will stay unaffected - in case of an error during such extraction, it will just pass 'null' as the filename. As another answer already pointed out, IE needs some special treatment, as always.
But with chromium edge coming in a few months, I wouldn't worry about that while building new apps hopefully. There is also the matter of revoking the URL, but I'm kinda not-so-sure about that, so if someone could help out with that in the comments, that would be awesome.
You may also download a file directly from your template where you use download attribute and to [attr. This simple solution should work on most browsers. This answer suggests that you cannot download files directly with AJAX, primarily for security reasons.
So I'll describe what I do in this situation,. Add href attribute in your anchor tag inside the component. Do all following steps in your component. If a tab opens and closes without downloading anything, i tried following with mock anchor link and it worked. You can return a Blob object from the server and create an anchor tag and set the href property to an object URL created from the Blob. Now clicking on the anchor will download the file.
You can set the file name as well. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow. Learn more.

This may be as low as GB. For large file downloads you need to specify a new tab e. I don't think there's a clean way to get around the large file size limitation with Ajax-style requests. Add a comment. Active Oldest Votes. One of the many ways that exist to solve this is as follows: this.
