One of the most important quality factors for websites is their speed. Websites have to be displayed quickly - with some providers, more than 50% of visitors drop off with a three-second delay. Fortunately, there are very easy-to-use tools that give insight into possible brakes and obstacles. One of the more popular of these tools is Google Page Speed Insights.
The use of PageSpeed Insights is actually quite simple: Enter the URL of the website, press the button and after a short waiting time go through the list of suggestions for improvement (best practices). Since an incorrectly placed JavaScript call or a CSS file that is integrated in the wrong place can destroy all further optimizations, an operator should check his website regularly. In day-to-day project work, it quickly becomes apparent that hardly anyone uses this tool on a regular basis. The three main reasons for this are:
At this point, the DevOps approach offers a solution. It automates the additional work and makes the verification part of the delivery so that it is carried out whenever the website changes. This turns an additional compulsory task into an automated test that shows possible need for optimization without further effort. In practice, the tool is integrated directly into the deployment pipeline. The measured data are then fed into a monitoring system. For example, if the pipeline uses the build system Gulpand for monitoring StatsD, it could contain the following code: var psi = require ( 'psi' ), StatsD = require ( 'node-statsd' ). StatsD , client = new StatsD (); psi ({ url : 'http://devops-blog.de/' }, function ( err , data ) { var results ; if ( data [ 'responseCode' ] === 200 ) { client . gauge ( 'PSI_Score' , data [ 'score' ]); results = data [ 'formattedResults' ] [ 'ruleResults' ]; for ( var result in results) { if ( results . hasOwnProperty ( result )) { client . gauge ( 'PSI_' + result , results [ result ] [ 'ruleImpact' ]); } } } }); With each deployment, all values determined by PageSpeed Insights are fed into the monitoring system. These values are then available together with all other determined metrics for automatic evaluation and alarming. If there is a need for optimization, the person responsible will be notified immediately. In the monitoring, he sees with which deployment the deterioration was introduced and which component is responsible. As a rule, he can therefore implement the necessary optimizations very easily. Page speed of a website is very important for SEO point of view also therefore most of companies always looking for professionals those can help to improve the Website speed.
