Angular show downloaded file

Thus, these browsers will render the error if using the Blob URL. The default fileName value is also picked up by the process. The PDF. For easy demonstration, the sample application uses the basically unmodified version of the PDF. All PDF. Pdf project. As the time of writing this article, the latest stable version of the PDF. This version works fine for all latest versions of major browsers except for Internet Explorer 11 in which a runtime error is thrown when closing the viewer in an IFrame.

The sample application that comes with the PDF. You can find all release versions of the PDF. In the below line, the iframe is the DOM object and the response. The Apple stopped to release the Safari for Windows after the version 5. Although the PDF. I do notice that the later versions of PDF. In the past, Web developers commonly use the code to explicitly check the browser types and versions for conditionally directing to executions of particular code sections.

The better practice now is to conduct the available option-based scenarios to resolve possible browser compatibility issues.

This allows us to pass in a strategy for persisting the download to a file without directly coupling the operator to FileSaver. By keeping FileSaver. The download operator can be tested without somehow mocking the saveAs import see here for corresponding tests.

If we apply the same pattern to the service, we'll be able to test it just as easy. So let's do that by creating a custom injection token for saveAs in a file called saver. Let's use the Progress Bar from Angular Material to show how far along our download is.

The component now only has to assign an observable download to this property:. We can then subscribe to this observable through the AsyncPipe in combination with NgIf. While the download is pending we'll display the progress bar in 'buffer' mode you may also use 'query' , otherwise the progress is determinate.

The bar's value can then easily be applied from Download. Pro Tip : If you need to map something to more than two values inside a template or rather a ternary statement won't do it for you: map the observable to the type you need or use a custom pipe instead of calling a component function from the template.

Both methods are pretty easy to write, more declarative and perform better. Here's a StackBlitz showing everything in action. The downloaded file is only 3MB, so you might want to enable throttling to see more of the progress bar.

I hope this article helped you with your project. Hire me , if you need further support solving your specific problem. Sometimes even just a quick code review or second opinion can make a great difference. With Sentry it's easy to log Angular errors server-side. In this example we create a designated service to track errors better than the browser console.

Saving changes automatically to the server improves user-experience. Here is the simplest way to download a file from an API that I was able to come up with.

Related 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.

The above line uses ready-made FileSaver module that will open the file with Save as option. I have created service class to fetch file data from a server URL but I need to provide a link or button for downloading the file. In the view file I will give users two options for downloading the same file.

I will use link as well as button for downloading the same file from the server. In the service class I have used Http module which may not be found automatically.
