: Wrap the response data in a new Blob instance.
When your backend provides a ZIP file via an API, you must handle the response as a (Binary Large Object) to ensure the file data isn't corrupted during the transfer. Implementation using Axios vue js download zip file
Downloading a ZIP file in a Vue.js application can be handled in two main ways: fetching an existing archive from a server or generating a ZIP dynamically on the client side. 1. Downloading an Existing ZIP from a Server : Wrap the response data in a new Blob instance
: Always call window.URL.revokeObjectURL(url) after the download starts to free up memory, especially for large ZIP files. you can use the JSZip library.
import axios from 'axios'; const downloadZip = async () => { try { const response = await axios.get('https://example.com', { responseType: 'blob', // Crucial for binary files like ZIPs }); // Create a URL for the blob const url = window.URL.createObjectURL(new Blob([response.data])); const link = document.createElement('a'); link.href = url; // Set the filename for the download link.setAttribute('download', 'archive.zip'); // Append to body, click, and clean up document.body.appendChild(link); link.click(); link.remove(); window.URL.revokeObjectURL(url); } catch (error) { console.error('Download failed:', error); } }; Use code with caution. 2. Generating a ZIP File on the Client Side
: This tells Axios to process the response as binary data.
If you need to bundle multiple individual files (like user-uploaded images or text) into a single ZIP without a backend, you can use the JSZip library. Implementation using JSZip : npm install jszip Add files to the ZIP : Use zip.file() to add content.
