Using Redis in Heroku for a React and Rails API - ruby-on-rails

Question

I have a Rails API deployed onto heroku, which serves to a React.js Static page. There both deployed on heroku, and they comunicate through an API link. My struggle is comming when using Redis and Sidekiq.
On my Rails API I got the RedisToGo link Configured with no issues, but when I go to my React app and try to send an email invite I get this message Redis::CannotConnectError: Error connecting to Redis on 127.0.0.1:6379 (ECONNREFUSED).
I thought if I have it configured on my backend then it would work to my react static page app.
Sidekiq.yml
---
:verbose: false
:concurrency: 3
staging:
:concurrency: 1
production:
:concurrency: 5
:queues:
- [mailers,2]
- slack_notifications
- mixpanel
- invoices
- default
- rollbar
Redis.rb
uri = URI.parse(ENV["REDISTOGO_URL"])
REDIS = Redis.new(:url => uri)
sidekiq.rb
Sidekiq::Extensions.enable_delay!
unless Rails.env == 'development' || Rails.env == 'test'
Sidekiq.configure_server do |config|
config.redis = {
url: Rails.application.credentials.redis_url,
password: Rails.application.credentials.redis_password
}
end
Sidekiq.configure_client do |config|
config.redis = {
url: Rails.application.credentials.redis_url,
password: Rails.application.credentials.redis_password
}
end
end
# Turn off backtrace if at all memory issues are popping up as
# backtrace occupies to much memory on redis
# number of lines of backtrace and number of re-tries
Sidekiq.default_worker_options = { backtrace: false, retry: 3 }
Sidekiq.configure_server do |config|
# runs after your app has finished initializing
# but before any jobs are dispatched.
config.on(:startup) do
puts 'Sidekiq is starting...'
# make_some_singleton
end
config.on(:quiet) do
puts 'Got USR1, stopping further job processing...'
end
config.on(:shutdown) do
puts 'Got TERM, shutting down process...'
# stop_the_world
end
end
So my question is the next one:
If I have already configured a REDISTOGO_LINK on my rails app, do I need the same on my react config vars?
Whats the best way to configure sidekiq and Redis on a Rails API using react as a front-end in heroku? I haven't seen something that covers this on the internet.
I would appreciate your help! ;)

You need to run heroku config:set REDIS_PROVIDER=REDISTOGO_URL to tell Sidekiq to use REDISTOGO_URL to connect to Redis.
