If you need to download a file from an endpoint that returns a file response, you can do so using the following code:
const newBlob = new Blob([response], { type: "text/csv" })
const data = window.URL.createObjectURL(newBlob);
const link = document.createElement("a");
link.href = data;
link.download = fileName; // specify a name for the file
link.click();
If you're looking to initiate a file download in Angular, the solution is straightforward:
const blobData = new Blob([responseData], { type: "text/csv" });
const url = window.URL.createObjectURL(blobData);
const anchorElement = document.createElement("a");
anchorElement.href = url;
anchorElement.download = desiredFileName; // specify the filename
anchorElement.click();
This snippet of code creates a Blob object with the response data and defines the MIME type of the file. Subsequently, it generates a URL for the Blob using window.URL.createObjectURL(). Then, an <a> element is created, setting the href attribute to the generated URL and the download attribute to the chosen file name. Finally, a click event on the <a> element triggers the file download process.
To download a file, consider using the msSaveBlob function as the initial approach. If that doesn't succeed, you can dynamically create an element but ensure to delete it afterwards.
function saveFileToDisk(blobData: Blob, fileTitle: string) {
if (window.navigator && window.navigator.msSaveOrOpenBlob) {
window.navigator.msSaveBlob(blobData);
} else {
const blobUrl = URL.createObjectURL(blobData);
const linkElement = document.createElement('a');
linkElement.href = blobUrl;
linkElement.download = fileTitle;
linkElement.style.display = 'none';
document.body.appendChild(linkElement);
linkElement.click();
URL.revokeObjectURL(blobUrl);
linkElement.remove();
}
}
When it comes to downloading a file in Angular, the process is quite simple. All we need to do is leverage the power of the HTML5 download attribute.
<!--angular-->
<a
href="FilePath.csv"
class="btn"
target="_blank"
download="FileName.csv"
>
Download Now
</a>
To start, we'll establish an assets folder within the src directory. This is where we'll store the file that we intend to download.
Next, we'll integrate the following code snippet into our app.component.html file.
