API Reference

Core analytics API

The core analytics API is exposed once the library is initialized with configuration.

TLDR; read the getting started guide

Using analytics

  1. Initialize analytics with configuration
  2. Export the analytics instance with third-party providers (Google Analytics, HubSpot, etc.)
  3. Use page, identify, track in your app
  4. Add an analytics provider
  5. Write custom plugins

Configuration

Analytics library configuration

After the library is initialized with config, the core API is exposed & ready for use in the application.

  • [config.app] (optional) string - Name of site / app
  • [config.version] (optional) string - Version of your app
  • [config.debug] (optional) boolean - Should analytics run in debug mode
  • [config.plugins] (optional) Array.<AnalyticsPlugin> - Array of analytics plugins

Example

import Analytics from 'analytics'
import pluginABC from 'analytics-plugin-abc'
import pluginXYZ from 'analytics-plugin-xyz'

// initialize analytics
const analytics = Analytics({
  app: 'my-awesome-app',
  plugins: [
    pluginABC,
    pluginXYZ
  ]
})
