Angular open downloaded pdf

The path or PDF filename is incorrect. Solution: Double check the path located in the viewer URL the? For example,? The PDF filename or its path contains spaces or characters that confuse the browser. Solution: Convert the filename or path to URL encoding. Solution: Unfortunately, PDF. The solution is to disable the download manager or configure it to not intercept PDF downloads.

We hope this was helpful! You can also have a look at PDF. Select a product PDF. So, this will straight forward to the usage or implementation of Angular HttpClient. For now, we will use existing Node. After this, the HttpClient feature will show you in an easy way and a little bit different from the original Angular docs.

It just versions compatibility updates of their dependencies. We assume that you have downloaded and installed Node. Now, let's check the above requirement by open the terminal or Node command line then go to your projects folder. Type this command to check the latest Node and NPM version.

By comparisons, the server-side approach is much more powerful and has more features and flexibility. For demo purposes, a PDF data report, Product Order Activity shown in the screenshot above , is generated from a static data source simulating the data from a database using the PdfDataReport tool I previously posted.

The PDF data document creation is not the focus of this article. The PdfFileWriter library built with the. NET Framework 4.

NET 5 projects. Drawing , System. Forms , System. DataVisualization , PresentationCore , etc. You can see how the ASP. You can also see how the ASP. Other items are also set for the response header before the response is returned to the caller. NET 5 except returning the custom response messages.

The ASP. When the custom headers and contents are required, the ASP. NET 5 method are omitted. You can also specify its value in order to set the name of the file being downloaded. You can bind any of these attributes with Angular in order to set the URL and filename dynamically:.

Older browsers, like the Internet Explorer, might not recognize the download attribute. If there's no download attribute, the filename for your download will solely depend on the HTTP header Content-Disposition sent by the server that's providing the file. The information from this header might also take precedence even if the download attribute is present. A link-based solution conforms well to HTML standards and lets the browser do most of the work.

However, if you want more control over the download and would like to display some custom progress indicator you can also download files via Angular's HttpClient. A file is best represented as a Blob in the browser:. The Blob object represents a blob, which is a file-like object of immutable, raw data -- MDN web docs. By specifying the responseType option we can perform a GET request returning a blob representing the downloaded file.

Let's assume we've got a designated DownloadService doing just that:. A component would then be able to call this service, subscribe to the corresponding observable and eventually save the file like this:. Here, we're creating an anchor tag programmatically when the blob arrives. With URL. Finally, we click the link like the user would've done with a regular browser download link. After the file is downloaded, we'll discard the blob by revoking the object URL we created. This approach is pretty verbose though and might not work smoothly for every browser.

Therefore I'd advise you to use the popular library FileSaver. The saving then becomes a one-liner:. If you don't like adding a dependency for this and would prefer to use the manual approach shown before, you might as well refactor the code for saving the blob into a separate service.
