You can do it like this using Node.js:
<pre><code>const firebase = require('firebase-admin');

async function deleteImageFromFirebase(imageName) {
 await firebase.storage().bucket().file(&quot;folderName/&quot;+imageName).delete();
}
</code></pre>
And like this client side:
<pre><code>// Create a reference to the file to delete
var desertRef = storageRef.child('images/desert.jpg');

// Delete the file
desertRef.delete().then(function() {
 // File deleted successfully
}).catch(function(error) {
 // Uh-oh, an error occurred!
});
</code></pre>
