Compares code formatting and formatting IR between Biome and Prettier to ensure that Biome's formatting is consistent and correct. Use when validating formatter changes, debugging formatting differences, or comparing output for JavaScript, TypeScript, CSS, or other languages.

General development best practices and common gotchas when working on Biome. Use for avoiding common mistakes, understanding Biome-specific patterns (AST, syntax nodes, string extraction, embedded languages), and learning technical tips.
Guide for creating and writing proper changesets for Biome PRs. Use when a PR introduces user-visible changes (bug fixes, new features, rule changes, formatter changes, parser changes) that need a changeset entry for the CHANGELOG. Trigger when creating changesets, writing changeset descriptions, or choosing the correct change type.

| compatibility | Designed for coding agents working on the Biome codebase (github.com/biomejs/biome). Requires bun and wasm-bindgen-cli. |
Use packages/prettier-compare/ to inspect any differences between Biome and Prettier formatting (including IR output) before shipping formatter changes.
bun (the CLI is a Bun script) and ensure dependencies have been installed.--rebuild so the Biome WASM bundle matches your current Rust changes.Snippets passed as CLI args:
bun packages/prettier-compare/bin/prettier-compare.js --rebuild 'const x={a:1,b:2}'
Force a language (useful when the tool cannot infer it from a filename):
bun packages/prettier-compare/bin/prettier-compare.js --rebuild -l ts 'const x: number = 1'
Compare files on disk:
bun packages/prettier-compare/bin/prettier-compare.js --rebuild -f src/example.tsx
Read from stdin (great for piping editor selections):
echo 'const x = 1' | bun packages/prettier-compare/bin/prettier-compare.js --rebuild -l js
-l/--language when formatting code without an extension so both formatters pick the correct parser.-f/--file for large samples or snapshot tests so you can iterate directly on project fixtures.packages/prettier-compare/README.md for deeper CLI details; mirror any updates here, keeping the hard requirement that commands include --rebuild.
