海外TECH	DEV Community	Why Is Website Performance Important And Tricks To Improve Front End Performance	https://dev.to/sharma2288/why-is-website-performance-important-and-tricks-to-improve-front-end-performance-f09	Why Is Website Performance Important And Tricks To Improve Front End Performance WHY DOES PERFORMANCE MATTER The performance of your website is important for accessibility and for other metrics that serve the goals of an organization or business Web performance has a direct correlation to user experience as well as the overall effectiveness of your site A slow website can deter users and drive them to your competition With this fast evolving consumer behavior one cannot risk overlooking the importance of website speed You should care about web performance Millions of different websites are browsed every day and half of them users close in a few seconds without giving them a possibility to impress share the content or sell the goods they advertise Why does it happen so A big percentage of websites are sluggish user unfriendly and browser incompatible Modern users are unlikely to spend their time on slow loading pages or poorly optimized websites In the context of web services such problems relate to poor front end optimization The goal of front end performance is to give users an ability to get what they want from a website or an application at a very limited time and ensure that they have a smooth experience while interacting with it Consider an example that you are running an e commerce website Performance is of major consideration as it is found that faster websites have lower shopping cart abandonment rates and higher conversion rates For e commerce websites milliseconds in extra load time can result in loss of revenue Similarly in case of content websites like wikis or blogs audience is everything If your website is slow it results in higher bounce rates and lower search engine ranking Now consider an example of intranet application like timesheet or internal portal a few seconds of load time might not be a big concern Below are some interesting facts on business impacts and conversions Etsy found that adding kb of hidden images to their mobile site increased their bounce rate by Walmart found that for every second of improvement they experienced increase in conversions Amazon found that every milliseconds in load time on amazon website resulted in decrease in sales Google found that when they increased the search results from to the load time increased by half a second and resulted in a decrease in ad revenues Google has admitted that performance is one of the factors in their page rank algorithm They recently began experimenting with red warning tags in search results which is essentially a digital performance based scarlet letter Reference Lastly let s consider the needs of our users and how performance fits into that Users expect the software to be functional reliable usable performant and pleasurable Below are a few statistics related to website speed Hopefully this will help you understand why page speed plays an important role in meeting the website performance standards of internet users are likely to abandon a website if it takes more than seconds to load of users expect a website to load in seconds or less of users that find your website to be slow will likely not return to your website again of the users will share their poor experience with the page speed and website loading with others PERFORMANCE METRICS Performance metrics are the new standards of performance There is no single metric or test that can be run on a site to evaluate how a user feels However there are several metrics that can be helpful indicators First paint The time to start of first paint operation Note that this change may not be visible it can be a simple background color update or something even less noticeable First Contentful Paint FCP The time until first significant rendering e g of text foreground or background image canvas or SVG etc Note that this content is not necessarily useful or meaningful First Meaningful Paint FMP The time at which useful content is rendered to the screen Largest Contentful Paint LCP The render time of the largest content element visible in the viewport Speed index Measures the average time for pixels on the visible screen to be painted Time to interactive Time until the UI is available for user interaction i e the last long task of the load process finishes Reference TOOLS TO MEASURE PERFORMANCE There are plenty of front end performance tools out there free and subscription based which allow you to audit the performance of your website and collect metrics covered in the previous section Below are two tools I have used and highly recommend LIGHTHOUSE Google Lighthouse is a tool with which you can perform an audit on your website You can use it as a simple Google Chrome extension or together with Chrome DevTools this is a collection of web developer tools directly in Chrome Reference text Lighthouse bookmark border amp text Lighthouse is an open Dsource web apps C SEO and more WEB PAGE TEST WebPageTest org is an open source website performance testing tool that allows you to benchmark your website from one of their locations and a wide range of devices You can also choose to simulate your tests over a slow mobile network or a fast G network The result will be graded from F to A and will include information on compression time to first byte TTFB caching waterfall charts for the resources load speed and more It also features an option where it can run a test times and display all three data sets This helps figure out if the DNS or CDN might cause any delay and if the server can respond to all requests It s a great tool to get results on how your website is performing It gives a detailed report and insights on several metrics and provides waterfall graph We can monitor for trends and spikes The waterfall chart gives insight into how assets and XHR calls are loading Once we get the report we can prioritize the impact and work towards addressing any issues URL webpagetest org GTmetrixGTmetrix allows you to get detailed information on your page speed timings performance score and much more GTmetrix also provides information about how to fix the issues that were exposed by the test Without registering you can only run a test from one location Vancouver Canada but after you sign up for a free account you ll get to choose your location different browsers and even the connection type This should paint a better picture of how your website works in different scenarios There are several other open source and paid tools that can be used to measure performance Here is a link that provides details of those toc google pagespeed insights TRICKS TO IMPROVE THE FRONT END PERFORMANCE This blog reveals front end performance optimization tips that will definitely be useful to drastically improve front end performance and enhance website speed to make sure the users won t cut short their visit Minification Minification removes unnecessary characters from a file to reduce its size thereby improving load times When a file is minified comments and unnecessary white space characters space newline and tab are removed This improves response time since the size of the download is reduced Image Optimization Images take up approximately of the average web page size which can make websites heavy and slow To reduce the image delivery time and boost the performance of a website we recommend using responsive images Responsive image techniques namely srcset sizes and elements allow the delivery of different scaled images based on the size and resolution of the accessing device Check waterfall and identify heavy assets taking the longest to load Optimize the assets by compressing images and use of “srcset attribute WebP formatted images are approximately up to smaller than JPEG and smaller than PNG formatted images Simply put just converting the image into WebP format can significantly decrease the size of the web page Just bear in mind that WebP format is not supported by Safari and iOS Safari Reduce number of requests Latency has a substantial impact on mobile application performance Reducing the number of unique objects on the page will help reduce sensitivity to latency Waterfall of network requests shows various requests Create sprite images that has images and use of SVG for vector assets Limit blocking requests Browser is waiting for requests before initially rendering blocking requests JavaScript CSS assets look to be the main offenders Make use of “defer or “async Use of media queries in CSS When loading a page during HTML parse if the browser comes across an external script like this … lt script src third party script js gt lt script gt …the browser fetches the script asynchronously and then pauses rendering so it can be executed This is bad because it slows the critical rendering path which will result in a worse first contentful paint metric The solution is to use the defer attribute like below lt script src third party script js defer gt lt script gt This instructs the browser to download the script as soon as it s found but it defers execution until after the HTML parsing is complete This sidesteps the problem of delaying the critical rendering path and is the recommended way to load rd party scripts that manipulate the DOM Increase the speed with caching Caching stores a copy of the asset that a user has requested and later accesses the cached copy instead of the original copy There are different types of caching that help to improve delivery speed Browser cache Files are stored in the browser local cache so when one wants to access them there is no need to download them from a server Cache server Cache servers are located in different geographic regions so that the user s requests don t have to travel far Memory cache Memory cache helps to speed up the data delivery process within an application by storing certain parts of data in SRAM Disc cache Like a memory cache disc cache stores data for it to be accessed faster within an application though it makes use of conventional RAM Use a content delivery network CDN The proximity of the mobile carrier s Internet gateway to web servers can impact response times Using a CDN brings content to servers that are closer to the user reducing latency and improving performance Remove unused CSS and JS While loading or running a page the coverage table in Google Chrome shows how much code was loaded and how much of it was actually used The size of the pages can be reduced by only shipping the needed code The process is the following first you load a page on Google Chrome then use a coverage tool in Dev Tools press Ctrl Shift P type “Coverage press Drawer Coverage As soon as the page is reloaded you can see how much unused code is there so you can find those modules and lazy load with import Then go to the coverage profile once again and confirm that it carries less code on initial load Lazy loading Usually when you load a web page the browser requests all of its images regardless of whether they re in the viewport or further down the page and out of sight Lazy loading allows us to only load the images which are visible and asynchronously load the rest on demand as the user scrolls This reduces the number of requests on load and can speed up the process considerably Trigger events animation only once you scroll amp lazy load the images Reduce the number of DOM elements complex page means more bytes to download and it also means slower DOM access in JavaScript Httparchive org reports an average of DOM elements per page Reduce the number of DOM elements on the page to improve performance Avoid empty SRC or HREF You may expect a browser to do nothing when it encounters an empty image SRC tag However this isn t the case in most browsers Safari will make a request to the actual page itself This behavior could corrupt user data waste server computing cycles generating a page that will never be viewed and in the worst case cripple your servers by sending a large amount of unexpected traffic References inverita frontend optimization tips to improve web performance afbefe FINAL THOUGHTS Hopefully you now know a little more about why optimizing front end web performance is important and how to accomplish it Now you can make this a part of your standard workflow and see the considerable benefits for yourself As you can probably there are a lot of options to choose from each with its unique feature and it s up to you to test them and figure out which one works best for you And like Yoda once said to Luke Lastly there are also a whole list of other things you can do to improve performance that are specific to the framework you re using Ex React Angular VUE The list mentioned in the article is not an all inclusive list	2022-01-06 10:04:08
