On October 15, 2024, New Relic will end of life the browser monitoring createTracer() API call.
New Relic is updating the browser SPA agent to be more performant, with improved accuracy and fewer lines of code. These updates simplify the agent, letting customers diagnose issues with their browser apps more easily. Before New Relic can update the browser SPA agent, we need to remove the createTracer() API.
Accounts using the createTracer() API at the time of end of life will lose performance metrics about their SPAs.
What you need to do
We recommend that you migrate to the addPageAction() API call to collect time data about sub-components on your pages.
See our doc on addPageAction for information on how to implement this API call.
