How to Use Base64 Placeholders with Angular’s NgOptimizedImage Directive

The NgOptimizedImage directive in version 17.2 of Angular now comes with the ability to pass a base64 data URL placeholder that is displayed while the main image is loading. This placeholder can be applied as a background-image style with a CSS blur effect. However, users have the option to disable the blur if preferred. The Angular team recommends keeping these placeholder images smaller than 4KB to ensure optimal performance.
