# Setup Sidekiq in a Rails 8 app



### Add the Sidekiq gem

```
gem 'sidekiq'
```

And remove (or comment out):

```
gem 'solid_queue'
```



### Add this line to all configs

Add to `development.rb`, `staging.rb`, `production.rb`:

```
config.active_job.queue_adapter = :sidekiq
```

And comment out the other lines (which are in staging and production configs):

```
# config.active_job.queue_adapter = :solid_queue
# config.solid_queue.connects_to = { database: { writing: :queue } }
```



### Add the Sidekiq web UI

Add this line to the very top of `routes.rb` (above the routes opening block)

```
require 'sidekiq/web'
```

Add this into the routes:

```

# Only mount Sidekiq Web UI if the user is authenticated as an admin
authenticate :user, lambda { |u| u.admin? } do
  mount Sidekiq::Web => '/admin/sidekiq'
end
```
