Help: PostHog Client available from all controllers/models

[leoplct]

I have added posthog client initialization in config/initializers/posthog.rb

config/initializers/posthog.rb

posthog = PostHog::Client.new({
    api_key: "phc_XXXX",
    api_host: "https://app.posthog.com", # You can remove this line if you're using app.posthog.com
    on_error: Proc.new { |status, msg| print msg }
})

How can I have the posthog variable available from all controllers/models in my projects? Maybe using a singleton?
It needs to be memory efficient and avoid instantiating multiple times the same PostHog::client object.

app/controllers/test_controller.rb

class ApiController < ApplicationController
  def test
   posthog.capture({
            distinct_id: 1,
            event: 'test',
            properties: {}
  end
end

SOLVED.
I suggest to add this in the documentation.

config/initializers/posthog.rb

::PostHogApi = PostHog::Client.new({
    api_key: "phc_XXXX",
    api_host: "https://app.posthog.com", # You can remove this line if you're using app.posthog.com
    on_error: Proc.new { |status, msg| print msg }
})

services/dev/analytics.rb

class Dev::Analytics
    def self.track(user_id, event, properties={})
        ::PostHogApi.capture({
            distinct_id: user_id,
            event: event,
            properties: properties
        })
    end
end

controller.rb

Dev::Analytics.track(current_user.id, 'event_name', {})
