Prettier was created in 2017 and has since seen a meteoric rise within the JavaScript community. It differentiated itself from other code formatters and linters by supporting minimal configuration, eliminating the need for long discussions and arguments by enforcing an opinionated style on its users. That enforcement ended up resonating well, as it allowed developers to get back to work on the more important aspects of their job.

Since then, it has expanded to support other languages and markup, including Ruby. The Ruby plugin is now in use in dozens of applications around the world, and better formatting is being worked on daily. This talk will give you a high-level overview of prettier and how to wield it in your project. It will also dive into the nitty gritty, showing how the plugin was made and how you can help contribute to its growth. You’ll come away with a better understanding of Ruby syntax, knowledge of a new tool and how it can be used to help your team.
