# @sankeyangshu/eslint-config

English | [简体中文](./README.zh_CN.md)

Sankeyangshu's ESLint flat configuration preset, includes Prettier.

## Features

- Format code with Prettier
- Default configuration supports JavaScript and TypeScript
- Supports JSON(5), YAML, Markdown, and other formats
- Opinionated, but highly customizable
- Optional support for Vue, React, Solid, Svelte, and Astro
- Automatically sorts imports, `package.json`, `tsconfig.json`, and other files
- Supports [ESLint Flat configuration](https://eslint.org/docs/latest/use/configure/configuration-files-new), easy to compose!
- Ignores files in common folders like `dist`, `node_modules`, `coverage`
- Respects `.gitignore` by default
- Reasonably strict, but improves code quality
- Requires ESLint v9.5.0+

## Install

```bash
pnpm i -D eslint @sankeyangshu/eslint-config
```
