angularjsHow do I use Angular to zip files?
Angular is a JavaScript framework used to build web applications. It can be used to zip files by using the JavaScript library JSZip. The following example code shows how to use JSZip to zip a file in Angular:
// Create a new instance of JSZip
let zip = new JSZip();
// Add a file to the zip
zip.file("hello.txt", "Hello World");
// Generate the zip file
let zipFile = zip.generateAsync({ type: "blob" });
// Create a download link
let downloadLink = document.createElement("a");
downloadLink.href = window.URL.createObjectURL(zipFile);
downloadLink.download = "example.zip";
downloadLink.click();
This code creates a new instance of JSZip, adds a file called hello.txt
with the content Hello World
to the zip, generates the zip file as a blob, and creates a download link for the zip file.
