## What it is
A shareable ESLint flat config preset by Anthony Fu that provides opinionated linting and auto-fix formatting for JavaScript, TypeScript, Vue, React, JSON, YAML, TOML, Markdown, and more with a single line of setup. It replaces Prettier via ESLint Stylistic, respects .gitignore, and ships a CLI wizard for one-command setup and legacy config migration.

## Use cases
- set up eslint for a typescript and vue project with one line of config
- replace prettier with eslint for code formatting
- migrate legacy eslintrc config to eslint flat config
- get an opinionated javascript code style preset with sorted imports and no semicolons
- lint json, yaml, toml, and markdown files out of the box
- enforce consistent code style across a javascript monorepo

## When to choose
- you want an out-of-the-box ESLint setup without hand-picking dozens of rules
- you prefer linting and formatting in a single tool instead of running Prettier alongside ESLint
- your project uses TypeScript, Vue, React, Svelte, Astro, Solid, or UnoCSS and you want first-class support
- you like Anthony Fu's code style (single quotes, no semicolons, sorted imports) and want it enforced automatically

## When to avoid
- you need a neutral, fully customizable baseline and dislike opinionated style choices like no semicolons
- you are still on ESLint below v9.5.0 or cannot adopt flat config
- your team requires strict control over every rule change, since this is a personal config that may change between releases (forking is recommended in that case)
