Automate Your Teams Code Style Guide with Prettier
I recently cloned the Sitecore JSS project from GitHub, hoping to build my own JSS application. Only a few code changes later and errors appeared. I feared the worst. 😱
The code I had written functioned properly, but did not meet the style guide requirements set by the project maintainers.
Let’s look more at the What and Why of Prettier, so we undedrstand why so many projects are using it!

Why use Prettier?
💡 Let Prettier enforce your style guide, not your code reviews.
Prettier can eliminate the overhead of a style guide by automating it. Remove the need for you to teach or even discuss your style guide. Thinking about your style guide is a thing of the past.
A few of the other reasons you’d want to use Prettier:
- Reduce the overhead of having to remember your style guide
- The Prettier config can be pushed into source control so it’s easy to distribute to the team
- Install Prettier into an existing codebase to help normalize the code
- You can even configure Prettier to auto format on save
