To download a file in the browser with Vue.js, we can make a GET request to get the file response data.

Then we can create a link from it and click on it programmatically to download the file.

For instance, we can write:

  <div id="app">
          label: 'example.pdf',
import axios from "axios";

export default {
  name: "App",
  methods: {
    async downloadItem({ url, label }) {
      const response = await axios.get(url, { responseType: "blob" });
      const blob = new Blob([], { type: "application/pdf" });
      const link = document.createElement("a");
      link.href = URL.createObjectURL(blob); = label;;

We have the downloadItem method that takes an object with the file url to download, and the label property which has the file name.

In the method, we call axios.get to get the data from the url .

We set responseType to 'blob' to let us download the data.

Next, we create a Blob instance with the which has the file contents.

type is set to the MIME type of the file.

Next, we use document.createElement to create the a element which we click to download the file.

We set its href to the URL created by URL.createObjectURL with the blob .

And then we set the download property to the label file name.

Then we call click to click on the a element to do the download.

And finally, we call URL.revokeObjectURL to clear the URL resources.
