如何以角度查找页面加载时间? [英] How to find page load time in angular?

问题描述

这是在angular2 +中查找页面加载时间的正确方法吗? 我不这么认为，这只是路由更改之间的时差.我们如何为其添加页面DOM内容加载时间.??

Is this the right way to find page load time in angular2+?? I don't think so, It's just the time difference between the route change.How can we add the page DOM content load time to it.??

this.router.events.subscribe((val) => {
    const navigationComplete = val instanceof NavigationEnd;
    const navigationStart = val instanceof NavigationStart;
    if(navigationStart){
        this.navigationStartTime = (new Date).getTime();
    }
    if (navigationComplete) {
        this.currentPage = this.router.url; // Current page route
        this.currentLocation = (this.platformLocation as any).location.href; // Current page url
        let endTime = (new Date).getTime();
        this.pageLoadTime = Number(endTime) - Number(this.navigationStartTime); // Page load time
    }
});

推荐答案

您绝对可以使用chrome dev工具来分析性能，如@AurA所述
在以上所有您可以初始化的脚本中分别进行

you can definitely use chrome dev tools to analyse perfomance as mentioned by @AurA
separately in the above all scripts you can initialise

<script type="text/javascript">
    var timerStart = Date.now();
</script>

以及主要部分

ngAfterViewInit(){
   console.log("Time until reaching run phase: ", Date.now() - $window.timerStart);
}

Havent经过测试.但应该运行.

Havent tested. But should run.
