StaticDelivr CDN

Beskrivelse

StaticDelivr CDN is a lightweight and powerful plugin designed to improve your WordPress site’s performance. By rewriting theme, plugin, core file resource URLs, optimizing images, and proxying Google Fonts through the StaticDelivr CDN, the plugin ensures faster loading times, reduced server load, better privacy, and an improved user experience.

StaticDelivr is a global content delivery network (CDN) that supports delivering assets from various platforms like npm, GitHub, and WordPress. By leveraging geographically distributed servers, StaticDelivr optimizes the delivery of your static assets such as CSS, JavaScript, images, and fonts.

Key Features

• Automatic URL Rewriting: Automatically rewrites URLs of enqueued styles, scripts, and core files for themes, plugins, and WordPress itself to use the StaticDelivr CDN.
• Image Optimization: Automatically optimizes images with compression and modern format conversion (WebP, AVIF). Turn 2MB images into 20KB without quality loss!
• Google Fonts Privacy Proxy: Serve Google Fonts without tracking — GDPR compliant. A drop-in replacement that strips all user-identifying data and tracking cookies.
• Automatic Fallback: If a CDN asset fails to load, the plugin automatically falls back to your origin server, ensuring your site never breaks.
• Separate Controls: Enable or disable assets (CSS/JS), image optimization, and Google Fonts proxy independently.
• Quality & Format Settings: Customize image compression quality and output format.
• Compatibility: Works seamlessly with all WordPress themes and plugins that correctly enqueue their assets.
• Improved Performance: Delivers assets from the StaticDelivr CDN for lightning-fast loading and enhanced user experience.

• Free and Open Source: Supports the open-source community by offering free access to a high-performance CDN.

Use of Third-Party Service

This plugin relies on the StaticDelivr CDN to deliver static assets, including WordPress themes, plugins, core files, optimized images, and Google Fonts. The CDN uses the public WordPress SVN repository to fetch theme/plugin files and serves them through a globally distributed network for faster performance and reduced bandwidth costs.

How It Works

StaticDelivr CDN rewrites your WordPress asset URLs to deliver them through its high-performance network:

Assets (CSS & JavaScript)

• Original URL: `https://example.com/wp-content/themes/theme-name/version/style.css`
• Rewritten CDN URL: `https://cdn.staticdelivr.com/wp/themes/theme-name/version/style.css`

This process applies to themes, plugins, and core files:

• Themes:
  Original: `https://example.com/wp-content/themes/twentytwentythree/1.0/style.css`
  CDN: `https://cdn.staticdelivr.com/wp/themes/twentytwentythree/1.0/style.css`

• Plugins:
  Original: `https://example.com/wp-content/plugins/woocommerce/assets/js/frontend/woocommerce.min.js`
  CDN: `https://cdn.staticdelivr.com/wp/plugins/woocommerce/tags/9.3.3/assets/js/frontend/woocommerce.min.js`

• Core Files:
  Original: `https://example.com/wp-includes/js/jquery/jquery.min.js`
  CDN: `https://cdn.staticdelivr.com/wp/core/tags/6.9/wp-includes/js/jquery/jquery.min.js`

Images

• Original: `https://example.com/wp-content/uploads/2024/01/photo.jpg` (2MB)
• Optimized CDN: `https://cdn.staticdelivr.com/img/images?url=https://example.com/wp-content/uploads/2024/01/photo.jpg&q=80&format=webp` (~20KB)

Google Fonts

• Original CSS: `https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600&display=swap`

• Privacy Proxy: `https://cdn.staticdelivr.com/gfonts/css2?family=Inter:wght@400;500;600&display=swap`

• Original Font Files: `https://fonts.gstatic.com/s/inter/v20/example.woff2`

• Privacy Proxy: `https://cdn.staticdelivr.com/gstatic-fonts/s/inter/v20/example.woff2`

This ensures faster delivery through StaticDelivr’s globally distributed network while protecting user privacy.
