Unminified JS Files

Priority: Critical

Impact: Negative

What issues it may cause​

Failure to minify JavaScript files can result in larger file sizes, leading to longer download times and slower page load speeds. This can negatively impact user experience, particularly for users on slower network connections or devices with limited bandwidth. Additionally, larger file sizes increase the load on servers and consume more network bandwidth, potentially leading to higher hosting costs and reduced server performance.

How do you fix it​

Minify JavaScript files before deploying them to your website. Minification tools remove unnecessary whitespace, comments, and other characters from JavaScript files, reducing their size without affecting functionality. Popular minification tools include UglifyJS, Terser, and Google's Closure Compiler.

Automate the minification process as part of your build or deployment pipeline to ensure that JavaScript files are minified consistently and efficiently.

What is the positive impact​

  • Faster page load times and improved overall performance, leading to a better user experience and higher user satisfaction.

  • Reduced data transfer times and bandwidth usage, resulting in lower hosting costs and improved server efficiency.

How to fetch the data for this report template​

You will need to run a crawl for report template to generate report. When report has been generated and you have crawl id you can fetch data for the report using the following query:

query GetReportStatForCrawl(
    $crawlId: ObjectID!
    $reportTemplateCode: String!
    $after: String
   ) {
      getReportStat(
        input: {crawlId: $crawlId, reportTemplateCode: $reportTemplateCode}
      ) {
        crawlSiteSpeedAuditOpportunities(after: $after, reportType: Basic) {
          nodes {
            opportunityDigest
            element
            title
            auditId
            exampleUrl
            wastedKibAvg
            urlCount
            wastedKibSum
            gaPageviewsSum
            savingsScoreSum
          }
          totalCount
          pageInfo {
            endCursor
            hasNextPage
          }
        }
     }
   }
