Single Page Applications (SPAs) allow your visitors to browse different pages on your site without having to reload the page completely. In most cases, a SPA website will still change the URL in the browser, even though the page is not being reloaded.
By default, Hotjar is able to detect and track these SPA URL changes automatically. If your SPA doesn't change the URL within the browser, check out Hotjar Settings for URL Changes for help.
Hotjar cannot track Forms within SPAs
Click on Settings, then Sites & Organizations from the Hotjar Dashboard.
Click the settings cog to open the Site Settings for the Site you would like to change.
Under URL CHANGES, you can select the tracking option that works best for your site.
If you are unsure of which tracking options work best for your site, take a look at Hotjar Settings for URL Changes for help.
