更快地构建DOM:使用预解析,async,defer以及preload.
Building the DOM faster: speculative parsing, async,defer and preload.
Learning about LD_PRELOAD.而另一方面,preload可以解决一些HTTP/2不能处理的问题。
On the other hand, preload can be used to resolve use cases that HTTP/2 cannot.
This is achieved using the“LD_PRELOAD method”.PreloadAudioData:audioclip将在场景加载的时候直接加载.
Preload Audio Data If enabled, the audio clip will be pre-loaded when the scene is loaded.原创警惕UNIX下的LD_PRELOAD环境变量.
You may already be familiar with Unix's$LD_PRELOAD environment variable.你可以通过设置preload="preload"来预先加载视频,或者之间添加preload也可以。
Videos can be preloaded by setting preload="preload", or by simply adding preload.Webpack内联指令还可以控制preload/prefetch。
Webpack inline directives also give some control over preload/prefetch.Preload是一个静态设置,可以在config/elasticsearch.yml中设置:.
Preload is a static setting that can either be set in the config/elasticsearch. yml:.动态连接的诀窍:使用LD_PRELOAD去欺骗、注入特性和研究程序.
Dynamic linker tricks: Using LD_PRELOAD to cheat, inject features and investigate programs.Preload另一个好处就是可以进行内容协商,而HTTP/2Push不能。
Another point in preload's favor is that it can perform content negotiation, while HTTP/2 Push cannot.设置环境变量LD_PRELOAD可以使得在安装之前有一个库被提前加载。
The LD_PRELOAD environment variable can be set to point to a library to be preloaded before installation.Preload是一个后台运行的守护进程,它分析用户行为和频繁运行的应用。
Preload is a daemon that runs in background and analyzes user behavior and frequently run applications.这个指令可以在<link>中使用,比如<linkrel="preload"gt;。
This directive can be defined within a<link>element for example as<link rel="preload"gt;.同样,环境变量LD_PRELOAD和LD_LIBRARY_PATH也可以被用户取消或者重置。
Also, the LD_PRELOAD and LD_LIBRARY_PATH environment variables can be overwritten/unset by the user.可以使用通配符来表示所有文件都应该预加载:index.store.preload:[“*”]。
A wildcard can be used in order to indicate that all files should be preloaded: index. store. preload:.如果你回到preload函数看看你会看到dude被加载为精灵图,而非图片。
If you glance back to the preload function you will see that'dude' was loaded as a sprite sheet, not an image.这使得你可以提供降级加载机制,以防止因为preload缺乏支持,而站点发生崩溃的情况。
That enables you to provide fallbackloading mechanisms in cases where the lack of preload support would break your site.由于preload的原因,我们改变了DOM规范,使得被支持rel关键字的特性检测成为了可能。
So as part of the preload effort, we also changed the DOM spec so that feature detection of supported rel keywords would be possible.例如,由于字体通常是页面上的重要资源,使用请求浏览器下载字体的preload一直是个好主意。
For example, since fonts usually are important assets on a page, it's always a goodidea to request the browser to download fonts with preload.如我们所见,使用Preload的应用知道资源加载的发生时机,并可在资源加载完毕后马上得到通知。
As we have seen, with preload the application is aware of the resource loading taking place, and can be notified once the resource was fully loaded.最近,我们至少会使用preconnect和dns-prefetch,我们会小心使用prefetch和preload;.
Most of the time these days, we will be using at least preconnect and dns-prefetch,and we will be cautious with using prefetch and preload;这些新的Web标准<linkrel="preload"gt;,使你能够实现更快的关键资源的加载,在这个月晚些时候,Firefox就能看到这些特性。
The fresh web standard<link rel=“preload”gt;, that allows you to load critical resources faster, is coming to Firefox later this month.大部分时间,我们至少会使用preconnect和dns-prefetch,我们会小心使用prefetch和preload;.
Most of the time these days, we will be using at least preconnect and dns-prefetch,and we will be cautious with using prefetch and preload;事实上,InianParameshwaran对HTTP/2Push和HTTPPreload进行了比较深入的研究,内容很不错,其中包含了您可能需要的所有细节。
In fact, Inian Parameshwaran did remarkableresearch comparing HTTP/2 Push vs. HTTP Preload, and it's a fantastic read with all the details you might need.考虑使用preload-webpack-plugin,它接受代码拆分的路由,然后提示浏览器使用<linkrel="preload"gt;或<linkrel="prefetch">预加载它们。
Consider using preload-webpack-plugin that takes routes you code-split and then prompts browser to preload them using<link rel="preload"gt; or<link rel="prefetch">
