Browser agent v1.291.0

v1.291.0

Features

Create the measure API

Adds the measure API to the newrelic global object. This API allows generating new BrowserPerformance data even if auto-detection of marks and measures is not enabled.

Bug fixes

Fix race between end of session and features aborting

Fix an issue where features would race with the session manager when a session ends. This required a check for session timings to match a given session and could create a state where a new session created from a pre-existing session would trigger a partial replay or no replay, and prevent the agent from sending trace data with a given replay.

Harvest first session trace payload immediately

For better consistency, implemented old behavior where the first ST payload is harvested immediately when the page loads. This helps ensure cases where replays are harvested but traces are not happen less frequently.

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.

v1.290.0

Features

Bundler tools exports

An optional Webpack splitChunks cacheGroup matcher is now available for users who build the agent via NPM. This matcher enables de-duplication and merging of the agent's lazy-loaded JavaScript into a single chunk. This single chunk loads post-page render, consistent with the behavior of our pre-built agent for APM and copy/paste implementations.

Set UserAction currentUrl before aggregation end

Set currentUrl on the first event of a user action instead of at the end of aggregation.

Improve lazy-loading optimization

Optimize our pattern to ensure that code-bundlers such as webpack can more effectively tree-shake the output to only include the relevant files needed to run the agent. This specifically helps reduce the bundle size, reduce the amount of lazy files generated, and streamlines "custom" agent builds used with NPM.

API Code Splitting

Split the API method definitions per feature instead of a single file shared across all loader types. This allows each loader to only instantiate the necessary APIs for the features included, and reduce overall bundle size for the "Lite" build as well as custom-built agents with NPM. A shell will still exist for non-initialized APIs to prevent errors from throwing on APIs used without the needed features.

Browser agent v1.290.0

versión 1.290.0

Característica

Exportaciones de herramientas de Bundler

Ahora está disponible un comparador de caché SplitChunks de Webpack opcional para los usuarios que crean el agente a través de NPM. Este comparador permite la desduplicación y la fusión del JavaScript cargado de forma diferida del agente en un único fragmento. Este único fragmento carga la representación posterior a la página, en consonancia con el comportamiento de nuestro agente prediseñado para APM y las implementaciones de copiar y pegar.

Establecer la URL actual de UserAction antes del final de la agregación

Establezca currentUrl en el primer evento de una acción del usuario en lugar de al final de la agregación.

Mejorar la optimización de la carga diferida

Optimice nuestro patrón para garantizar que los agrupadores de códigos como webpack puedan alterar de manera más efectiva la salida para incluir solo los archivos relevantes necesarios para ejecutar el agente. Esto ayuda específicamente a reducir el tamaño del paquete, reduce la cantidad de archivos diferidos generados y agiliza las compilaciones de agentes "personalizados" empleadas con NPM.

División de código API

Divida las definiciones de métodos de API por característica en lugar de un solo archivo compartido entre todos los tipos de cargadores. Esto permite que cada cargador solo cree instancias de las API necesarias para la característica incluida y reduce el tamaño general del paquete para la compilación "Lite", así como para el agente creado a medida con NPM. Todavía existirá un shell para las API no inicializadas para evitar que se produzcan errores en las API empleadas sin la característica necesaria.

Declaración de apoyo

Browser agent v1.288.0

v1.288.0

Features

Prevent storing session data past session expiry

There may be edge cases where some Session Replay/Session Trace data could be stored even though the agent session has expired. Add instrumentation to detect such occurrences and skip storing these events for the time being.

Introduce isFirstOfSession attribute on InitialPageLoad events

To help support User Journeys, the isFirstOfSession custom attribute will be added to BrowserInteraction events of initial page load kind if the page is the first of a new session.

Bug fixes

Reset notified when replay stops recording

Resolves an issue where JavaScriptError events would be missing the hasReplay attribute after session recording is resumed (for example, from user clicking on another tab/tab going idle and then coming back to it).

Solve race condition in logging abort

If the logging feature aborted before the agent had set up the event buffer, it could throw errors. This was addressed by checking for the presence of the event buffer before running methods against it.
