Dynamic Asset Versioning

Description

WordPress asset versioning can be a double-edged sword: on one-hand, it’s extremely effective for cache-busting, ensuring you aren’t sharing stale scripts or styles to your visitors. On the other hand, having to manually increment a version number is a pain (even as a constant), often resulting in a version control history full of “bumping the version number” commits.

Dynamic Asset Versioning aims to simplify this process: if an enqueued asset doesn’t have an explicit version number, the plugin will get the timestamp of the last time the file was changed and use that as the version number. It’s easy: you touch the file, the version number is updated automatically.

Usage

Once Dynamic Asset Versioning is active, it will automatically determine version numbers based on file modification time for any [non-core] files that have been enqueued using wp_enqueue_style() or wp_enqueue_script().

Example

wp_enqueue_style(
    'my-theme-styles',
    get_template_directory_uri() . '/assets/css/my-styles.css',
    array( 'some-other-styles' ),
    false, // Don't worry about it, Dynamic Asset Versioning has you covered!
    'screen'
);
