Prettier

In plain words

Prettier is an opinionated code formatter that automatically reformats code according to a consistent style. It works with multiple programming languages and removes the need for developers to manually adjust formatting or debate style conventions. By enforcing a single, predefined style, Prettier helps development teams maintain consistency across codebases while reducing time spent on formatting decisions. The tool is open source and available for use by software engineers and development teams.

  Pretty-print your chess games using Prettier2025 · github.com · ▲103

  Hi, As an enthusiast chess player, I like to manage my games and my opening repertoire as a set of PGN files stored in a Git repository (PGN is a text file format for recording chess games). So I wanted a way to pretty-print PGN files using a CLI and integrating in my editor. Today, it looks like most people use GUI-based software. So I decided to create a Prettier plugin that formats PGN files. Prettier is a well-known pretty-printer in the Node.js ecosystem, used to ensure consistent source code formatting in software projects. One upside of implementing this PGN formatter as a Prettier…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
