Browser Agent and SPA API

New Relic Browser includes an agent API you can use to report additional data and events to New Relic Browser and New Relic Insights. To use the API, follow these guidelines:

  • The API relies on a newrelic object that is automatically defined by the Browser JavaScript snippet described in the install documentation.
  • The Browser JavaScript must be present on each page in which you want to use the API.
  • The app's instrumentation level setting does not affect the availability of API functions.

In addition, if you are using Browser's single-page application (SPA) monitoring, you can use the SPA API to add custom monitoring of specific browser interactions. This is useful for monitoring interactions that aren't recorded automatically by New Relic because they don't result in route changes, such as a dynamically-updated widget. The SPA API also allows you to turn off default monitoring for interactions that you do not consider important enough to monitor.

Reports a Browser PageAction event to Insights along with a name and attributes.
Adds a unique name and ID to identify releases with multiple JavaScript bundles on the same page.
Adds a JavaScript object with a custom name, start time, etc. to an in-progress session trace.
Records an additional time point as "finished" in a session trace, and sends the event to Insights.
Identifies a browser error without disrupting your app's operations.
Adds a user-defined attribute name and value to subsequent events on the page.
Allows selective ignoring of known errors that the Browser agent captures.
Groups page views to help URL structure or to capture the URL's routing information.
SPA: createTracer
