Continuing on from the previous episode, we look at creating a Docker Swarm cluster and using Traefik to load balance and route requests to various applications. Using this and CloudFlare proxies, we're able to create and deploy hobby applications in minutes.

User experience is important and there are little things that we can do to help improve this experience. By giving real time feedback on text inputs to approaching limits on fields, the user can modify and update their text accordingly before they submit the form. In this episode, we look at database level, model validations and limiting text input on the client side.

Chart.js is a simple yet flexible JavaScript charting library for the modern web. In this episode, we look at creating a Stimulus controller around Chart.js. We'll also look at making the chart interactive by adding zoom and pan functionality.

Sometimes we find ourselves in a situation where we are handling the releases for an important application in our organization, but with each release, a regression/happy path testing must occur. We can use Ruby and Capybara to test these external sites.

Solid Cache is a database-backed Active Support cache store implementation. Using SQL databases backed by SSDs we can have caches that are much larger and cheaper than traditional memory only Redis or Memcached backed caches. In this episode, we'll explore adding Solid Cache into our application and some things to be aware of.
