Prettier is an opinionated code formatter with 50K+ GitHub stars that enforces a consistent style by parsing and reprinting code with its own rules. Supports JavaScript, TypeScript, CSS, HTML, JSON, Markdown, YAML, GraphQL, and more. Eliminates style debates in code reviews by making formatting automatic and deterministic. Features minimal configuration by design, editor integration for format-on-save, and pre-commit hooks via husky. The de facto formatting standard for web development.

Prettier enforces consistent code formatting by parsing and reprinting code with its own rules. 50K+ stars, the default formatter for web development projects worldwide.

Supports JavaScript, TypeScript, CSS, SCSS, HTML, JSX, JSON, Markdown, YAML, GraphQL, and more. Opinionated by design — minimal configuration options eliminate style debates.

Editor integration enables format-on-save in VS Code, JetBrains, Vim, and others. Pre-commit hooks via husky and lint-staged ensure all committed code is formatted.

Often paired with ESLint — Prettier handles formatting while ESLint handles code quality rules. The eslint-config-prettier package resolves conflicts between them.
