setAttribute (SPA API)

Syntax

newrelic.interaction().setAttribute(string $key, any $value)

Adds a custom SPA attribute only to the current interaction in browser.

Requirements

• Browser Pro+SPA agent (v963 or higher)

• If you're using npm to install the browser agent, you must enable the spa feature when instantiating the BrowserAgent class. In the features array, add the following:

  import { Spa } from '@newrelic/browser-agent/features/spa';
  
  const options = {
    info: { ... },
    loader_config: { ... },
    init: { ... },
    features: [
      Spa
    ]
  }

  コピー

  For more information, see the npm browser installation documentation.

Description

This method adds a custom attribute to an interaction. If saved, this attribute will be exposed as a new property on the resulting BrowserInteraction event. Unlike attributes added with setCustomAttribute(), an attribute added to an interaction will only apply to the current interaction, and it will not be added to PageAction events.

New Relic merges these custom attributes with the custom attributes set by calling setCustomAttribute() and with custom attributes set by a server-side agent.

Errors for custom attributes will be included in events on the JS Errors page. To view or log errors for a custom attribute via API, use the browser agent API's noticeError call.

Parameters

Return values

This method returns the same API object created by interaction().

Examples

router.addRoute('/profile', () => {
  const user = getCurrentUser();
  newrelic.interaction()
    .setAttribute('username', user.username)
    .setAttribute('userId', user.id);
  renderProfile(user);
});
