HTTP Archive Viewer for Chrome - Allows you to inspect HAR log files generated by browser's HAR Viewer – Web application that allows visualizing HTTP Archive logs (HARs) HARview – Versatile command line viewer of HAR files. The Internet contains several online HAR viewers, however we would all be more comfortable viewing our HAR files locally on our computers.

If you like this content, follow me on Twitter and GitHub.If you are trying to view a recent capture of a HAR (HTTP Archive) file, you may be wary about submitting your HAR file to online websites in order to view it. Since you have detailed information about their content, you can compare what has improved (or in some cases, not improved) after a new feature is launched or a redesign is completed, for example.ĭuring my workflow, I like to keep track of the final size/time values of a few pages of the product that I am working on. HAR files can be useful to collect information about the assets of a page. Using HAR files to analyze the performance of a page What I like about this viewer in particular is the fact you can have multiple files open at the same time, which makes it easier to compare them. My personal favourite is the one created by Jan Odavarko. Once you have a HAR file, you can try a few HAR viewers online.

What is a HAR file?Ī HAR (short for HTTP Archive) file is a JSON file containing all information about a browser’s interactions with a page. So how do we keep track of what is being analyzed by the Network tab? By exporting the page in HAR format. Performance improvements are noticeable by changes in your code/environment. Last, but not least, the waterfall column demonstrates when the asset is loaded along with the other requests. The size value will present the gzipped size of the resource (when applicable), while the time column shows the total duration from the start of the request to the receipt of the final byte in the response. The size, time and waterfall columns will be crucial to understanding the performance of a page. You can add more information to this table by right-clicking one of the table headers and choosing other columns. It will also show you relevant information about the origin of those assets (domain, HTTP status code, size), who initiated the request, and the order in which they were loaded in a waterfall representation. The network tab will give you a table containing all assets loaded on the page. I think about looking at the requests of a page, understanding what resources are being loaded, and how long these resources take to be available to users. When I consider the performance of a website, several things come to mind.
