I saw a lot of example code that worked with window. So this solution did not work for me. Then you just call the click event of that link and the download will be started. Obviously it is also easy to put in some spinner code etc…. One remark here…. I would think a download is pulling it into the browser? For some reason it feels like there should be a simpler way to download an excel file……. Add check for IE if navigator. I need to provide a link to download a file, the link must be hidden and accessible by any users, Here is my code , there are no errors whatsoever, but I can't even get the download dialog box to open:.
I had to achieve the functionality. Also had to make sure that it works for all the major supported browsers. Here's the solution for the same!!! You can try to "hide" protective params like e. By knowing this, your solution is pretty easy.
No ng-click is needed here. Unfortunately the download attribute is not supported by Safari browser. This doesn't realy matter while the browser is handling the download itself. Depending on the users system OS configuration the file will be downloaded or directly opened in a programm installed on that system. I hope this is what you need. Stack Overflow for Teams — Collaborate and share knowledge with a private group. 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. You can also create a custom injection token for URL - also see below how we'll do this for FileSaver.
By setting the option observe to events while making an HTTP request, we won't just receive the final response body of the request but also get access to intermediate HTTP events. We also need to explicitly pass the option reportProgress in order to receive HttpProgressEvents. Our HTTP request will eventually look like follows:.
Since we don't just want to forward these events to every component, our service has to do some more work. Otherwise our component would have to deal with HTTP specifics - that's what services are for! Instead let's introduce a data structure representing a download with progress:. A Download can be in one of three states.
Either it hasn't started yet, therefore it's pending. Otherwise it's done or still in progress. 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.
Angular is a UI user Interface framework for building rapid application development. You can use any server side technology and integrate this example with it for downloading file from server. I am going to use here Spring Boot framework as a server side technology. I will provide link as well as button, on which user will click and download the file from server.
I will also show how to give end users Save as option while downloading file and how to display file content on the browser.
Go through the following steps for creating Angular project to download file from server using Angular. Go through the link Creating Angular Project to create a new project. Make sure you give the project name as angular-file-download. For Angular 11 , you will find another option to set whether you want to use stricter type or not.
Here I am using stricter type and later I will show you how to use stricter type for response and error. Remember the file extension ts service. Service is one of fundamental blocks of every Angular application.
