Static Files Autoversioning Plugin for Craft CMS

This plugin is a Twig extension that helps you cache-bust your static assets, such as CSS, JS, images, videos, or PDFs. It appends a version number to the asset URL, based on either a build number or the file’s last modified time. This ensures that your users always receive the most recent version of your files, without having to clear their browser cache.

Installation

Project Setup

To install the plugin, navigate to your Craft project in your terminal:

Usage

To use this plugin, you need to call the version() function in your template, passing the asset path as an argument. For example:

This will output something like:

The version number (v=12345678) is determined by reading a file named build.txt in your root project folder (alongside config, templates, etc.). You can create and update this file using your deployment script. For instance, if you’re using CodeShip, you can use the following command:

Advanced Usage

Versioning from a String

If you want to use a custom string as the version number, you can use the versionString() function, passing the asset path and the string as arguments. For example:

This will output something like:

Versioning from a Timestamp

If you want to use the file’s last modified time as the version number, regardless of the existence of the build.txt file, you can use the versionTimestamp() function, passing the asset path as an argument. For example:

This will output something like:

Versioning from a Custom Text File

If you want to use the content of a custom text file as the version number, you can use the versionCustom() function, passing the asset path and the text file name as arguments. The text file should be located in your root project folder. For example:

This will output something like:

Assuming that the mods.txt file contains the word “modded”.

Versioning with PDF Generator or Varnish Cache

You can also use this plugin with PDF Generator when your hosting or server is caching PDF files. Or your files are cached by caching plugins like Varnish Cache.

This will output something like:

This generates a PDF with a version number, solving any caching policy issues with your hosting.

Note about paths

By default, the plugin searches for files to version in the @webroot directory, and for the build.txt or custom text file in the @root path.

Note: You can learn more about the @webroot and @root aliases and how to configure them in the Craft CMS documentation.
