NitroPack WordPress 插件

描述

NitroPack is the all-in-one performance optimization service. It combines everything you need for a lightning-fast website. Image optimization, code minification, caching, CDN, lazy loading – you name it, NitroPack has it.

NitroPack performs all optimizations in the cloud. This makes it a very lightweight solution with a lower CPU overhead compared to standard caching plugins.

Our service provides you with the following (typically paid extra) functionalities included without the need for additional configuration:

• Cloudflare CDN – we automatically serve your static assets from a CDN based on Cloudflare
• Image Optimization – we optimize all of your images automatically and convert them to WebP
• Cache Warmup – we keep your most important pages optimized at all times

Apart from these, NitroPack offers other unique features and benefits like:

• Incredibly Simple Setup – getting started with NitroPack is a breeze. There’s no technical configuration or a 15-step installation process. And you don’t need to be a developer to set it up. Simply follow these 4 steps and you’ll be done in no time
• No risk of damaging your original site files – NitroPack works on copies of your site files. You don’t like the results from an optimization? No problem. Purge your cache and start over. Even if you decide to disable NitroPack your site will go back to the state it was in before activating our plugin
• Cache Invalidation – you can invalidate cache files instead of purging them. This allows NitroPack to keep serving your visitors from cache while a fresh copy of the cache is being generated in the background. Cache invalidation is awesome for high traffic situations like campaigns. It allows you to keep updating your site while still serving cache to your clients. And with NitroPack, cache invalidation happens automatically. (For more info on this, scroll down to the “NitroPack and Campaigns” section)
• Critical CSS tailored to each of your unique layouts – most plugins that provide critical CSS functionality prepare a single critical CSS file per post type. Even when you have multiple pages with the same post type but different layouts. NitroPack detects this and generates unique critical CSS for each unique layout. Oh, and because desktop and mobile devices have different viewports, NitroPack also uses different critical CSS for each device type ?
• Optimize resources linked statically into your theme files – NitroPack will discover and optimize all resources linked into your theme, even ones that come hardcoded into your CSS files (even if they are multiple levels down an @import chain)

The configuration requires no technical knowledge. All you need to do is select your desired optimization level: Standard, Medium, Strong or Ludicrous. Besides that, NitroPack does all the work.

Running Marketing Campaigns with NitroPack

Two major issues often come up when running a campaign. First, each visitor hits your server with a unique URL request. Second, you lose your cache if you update content on your site.
Most optimization plugins come up short when it comes to both issues.
At the same time, NitroPack has two powerful features that help you thrive in these high traffic situations:

1. NitroPack recognizes campaign parameters in the URL and ignores them when looking up a cache file for the campaign request.
2. Cache invalidation – typically, when you update content on your site, caching plugins have to purge their cache and start rebuilding it. When a purge occurs during a high traffic period your visitors will no longer be served from cache. And your server will have to work extra hard to generate new cache files. As a result, the user experience on your website takes a hit. NitroPack solves this problem by invalidating the cache, instead of purging it. This method allows NitroPack to refresh the cache files in the background. At the same time, you still serve your clients from the slightly outdated cache files. As we already said, this happens automatically. You don’t need to worry about caching during an important campaign.

Whether you’re running a big campaign or your site suddenly becomes trending, both features are crucial for keeping your visitors happy.
So, if you want a fast website right now, go over to the Installation section and download NitroPack.

Incompatible Plugins

WordPress is designed to have only a single active page cache solution at a time, otherwise conflicts can arise. We do not recommend using NitroPack together with another caching plugin, like:

• WP Rocket
• Autoptimize
• Swift Performance
• WP Fastest Cache
• WP Fastest Cache Premium
• Powerpack (WPTouchPro)
• W3 Total Cache
• Breeze
• PhastPress
• WP Super Cache
• Litespeed Cache
• Swift Performance
• PageSpeed Ninja
• Comet Cache by WP Sharks
• Hummingbird
• SG Optimizer
• WP-Optimize – only the page caching must be disabled, not the entire plugin
• Smush – only the lazy load option must be disabled, not the entire plugin
• JetPack – only the lazy load option must be disabled, not the entire plugin
• ShortPixel – only the WebP conversion option must be disabled, not the entire plugin
