Download a File from Rest Api in Angular

In this tutorial, we are going to learn about how to download a file from rest api in angular with the help of an example.

Downloading a file from rest api

To download a file from rest api, first wrap the button element in a <a> tag then add the download attribute to the a tag. So it creates a download link.

Here is an example, which downloads the following twitter image when a user clicks on the button:

app.component.html
<div>
  <a href="/img/twitter.png" download>
    <button>Dowload image</button>
  </a>
</div>

In the above example, we have added the download path of a file to the href attribute.

Similary, you can create a download link for the pdf files like this.

<a href="/files/my-tax.pdf" download>
    <button>Download Tax Data</button>
</a>

Adding the new filenames

We can also add the new filename to a downloaded file by adding a value to the download attribute.

Example:

<a href="/img/fb.png" download="facebook">
   <button>Dowload image</button>
</a>

Now, our new downloaded filename will be facebook.png instead of fb.png.
