Generating a HAR file for troubleshooting

Nodecraft Support may occasionally need additional information about issues you're having viewing the Nodecraft website, essentially the network requests generated in your browser. A team member may ask you to record a HAR file, or a log of network requests, while that issue occurs.

What is a HAR file?

HAR is the short form for HTTP Archive format, which tracks all the logging of a web browser's interaction with a site. HAR files can be used to troubleshoot issues, specifically for problems such as performance and page rendering.

Creating a HAR file
