Browser agent v1.230.0

April 10, 2023


Add persistence for custom attributes

Custom attributes may now optionally be persisted between page loads via session storage. The API method setCustomAttribute now takes a third parameter, which defaults to false. When true, this boolean indicates that the provided custom attribute should be persisted in session storage and restored on subsequent page loads. Session storage is subject to the same-origin policy of the browser.

Add setUserId API

A new setUserId API method is now available. It defines a custom attribute containing a specified user ID, to be included in all payloads. The setUserId API is an extension of the setCustomAttribute API and automatically persists between page loads.

Fix npm package browser targets

The previous npm package release included code that was not compatible with browsers in our supported browser list. The package exports will now default to code that matches our browser support list. The package will also include the source code for power users that would like more control over how the agent is built.

Fix npm package exports

Some dangling, unused, and non-existent imports and exports were causing issues with consuming the NPM package in some projects. These have been removed.

Fix npm package import for typescript projects

Fixed an issue where typescript projects attempting to import the browser agent library would not get proper auto-complete in the import statement and would receive module declaration errors. The browser agent will not use tsc to generate type definitions from the JavaScript code at build time. The package.json has been updated with appropriate type export declarations.

Add error catch around sendBeacon

Added error catch logic around the sendBeacon usage. In the event sendBeacon throws an error during the final harvest, the final harvest will attempt to fall back to the image data submission method.

Remove array reduce polyfill

Removed the array reduce polyfill in favor of the native browser array reduce method.

Support statement:

New Relic recommends that you upgrade the agent regularly to ensure that you're getting the latest features and performance benefits. Older releases will no longer be supported when they reach end-of-life. Release dates are reflective of the original publish date of the agent version.

New Browser Agent releases are rolled out to customers in small stages over a period of time. Because of this, the date the release becomes accessible to your account may not match the original publish date. Please see this status dashboard for more information.
