Add Custom Icon in Ionic 2

Question

This is the easiest way I’ve found, from the forums at https://forum.ionicframework.com/t/anyway-to-custom-the-tabbars-icon-with-my-own-svg-file/46131/36.

In your app.scss file, add the following code:

ion-icon {
    &[class*="appname-"] {
        // Instead of using the font-based icons
        // We're applying SVG masks
        mask-size: contain;
        mask-position: 50% 50%;
        mask-repeat: no-repeat;
        background: currentColor;
        width: 1em;
        height: 1em;
    }
    // custom icons
    &[class*="appname-customicon1"] {
        mask-image: url(../assets/img/customicon1.svg);
    }
    &[class*="appname-customicon2"] {
        mask-image: url(../assets/img/customicon2.svg);
    }
    &[class*="appname-customicon3"] {
        mask-image: url(../assets/img/customicon3.svg);
    }
}

Then in your templates, you can use the following HTML to create the icon:

<ion-icon name="appname-customicon"></ion-icon>

This is far less complicated than using the font-based methods. As long as you’re not adding hundreds of icons you should be okay with this method. However each image is sent as a separate request, where as with the font methods all the images are contained in one file, so it would be a little more efficient.
