Track the initial traffic source of visitors to your site.

This plugin will save the original __user_original_source & __user_original_landing_page to localStorage and on the user properties in the sessions context.

Example:

__user_original_source = "source=(direct)|medium=(none)|campaign=(not set)"
__user_original_landing_page = "https://www.site.com/landing-page"

This data is handy when assigning attribution metrics.

npm install analytics
npm install @analytics/original-source-plugin

import Analytics from 'analytics'
import { originalSourcePlugin } from '@analytics/original-source-plugin'

const analytics = Analytics({
  app: 'my-app',
  version: 100,
  debug: true,
  plugins: [
    originalSourcePlugin(),
  ]
})

Replaces deprecated analytics-plugin-original-source package.
