Hey, I'm Fabio and I've been contracted by the Prettier team to speed up Prettier's command line interface (CLI). In this post we'll take a look at the optimizations I've discovered, the process that lead to finding them, some exciting numbers comparing the current CLI with the new one, and some guesses about what could be optimized next.

Prettier offers insights into code formatting, code styling, and automated code formatting tools, providing documentation, tutorials, and integrations for enforcing consistent code style across projects. By exploring Prettier's curated content, developers can learn about JavaScript, TypeScript, CSS, and HTML formatting rules, as well as editor integrations and CLI options for integrating Prettier into their development workflow. Whether you're working on frontend projects, backend APIs, or full-stack applications, Prettier offers resources to improve code readability, maintainability, and collaboration among team members.
