Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@eonova/eslint-config 使用指南

本项目纯自用,感谢antfu大佬,代码forks自 antfu/eslint

用法

启动向导

我们提供了一个 CLI 工具帮助初始化项目或迁移到新配置:

pnpm dlx @eonova/eslint-config@latest

手动安装

如果手动设置:

pnpm add -D eslint @eonova/eslint-config

并在项目根创建 eslint.config.ts

// eslint.config.ts
import eonova from '@eonova/eslint-config'

export default eonova()

使用 @eslint/eslintrc 转换旧格式配置:

import { FlatCompat } from '@eslint/eslintrc'
// eslint.config.ts
import eonova from '@eonova/eslint-config'

const compat = new FlatCompat()

export default eonova(
  {
    ignores: [],
  },

  // 旧配置
  ...compat.config({
    extends: [
      'eslint:recommended',
      // 其他扩展...
    ],
  })

  // 其他扁平配置...
)

注:Flat 配置中 .eslintignore 已失效,详细自定义方法见 自定义配置

添加 npm 脚本

package.json 中添加:

{
  "scripts": {
    "lint": "eslint .",
    "lint:fix": "eslint . --fix"
  }
}

IDE 支持(保存时自动修复)

VS Code 支持

安装 VS Code ESLint 扩展,添加以下设置到 .vscode/settings.json

{
  "prettier.enable": false,
  "editor.formatOnSave": false,

  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": "explicit",
    "source.organizeImports": "never"
  },

  "eslint.rules.customizations": [
    { "rule": "style/*", "severity": "off", "fixable": true },
    { "rule": "format/*", "severity": "off", "fixable": true },
    { "rule": "*-indent", "severity": "off", "fixable": true },
    { "rule": "*-spacing", "severity": "off", "fixable": true },
    { "rule": "*-spaces", "severity": "off", "fixable": true },
    { "rule": "*-order", "severity": "off", "fixable": true },
    { "rule": "*-dangle", "severity": "off", "fixable": true },
    { "rule": "*-newline", "severity": "off", "fixable": true },
    { "rule": "*quotes", "severity": "off", "fixable": true },
    { "rule": "*semi", "severity": "off", "fixable": true }
  ],

  "eslint.validate": [
    "javascript",
    "javascriptreact",
    "typescript",
    "typescriptreact",
    "vue",
    "html",
    "markdown",
    "json",
    "jsonc",
    "yaml",
    "toml",
    "xml",

    "astro",
    "svelte",
    "css",
    "less",
    "scss",
    "pcss",
    "postcss"
  ]
}

自定义配置

基础配置

导入 eonova 预设并导出配置:

// eslint.config.ts
import eonova from '@eonova/eslint-config'

export default eonova()

进阶配置示例

// eslint.config.ts
import eonova from '@eonova/eslint-config'

export default eonova({
  type: 'lib',
  stylistic: {
    indent: 2,
    quotes: 'single'
  },
  typescript: true,
  vue: true,
  ignores: ['**/fixtures'],
  jsonc: false,
  yaml: false
})

多配置组合

通过 FlatConfigComposer 组合多个配置:

import {
  combine,
  javascript,
  typescript,
  vue
} from '@eonova/eslint-config'

export default combine(
  javascript(),
  typescript(),
  vue()
)

插件重命名

若需恢复原始插件前缀:

import eonova from '@eonova/eslint-config'

export default eonova()
  .renamePlugins({
    ts: '@typescript-eslint',
    yaml: 'yml',
    node: 'n'
  })

支持的扩展配置

Formatter 支持

启用外部格式化器:

import eonova from '@eonova/eslint-config'

export default eonova({
  formatters: {
    css: true,
    html: true,
    markdown: 'prettier'
  }
})

需安装依赖:

pnpm add -D eslint-plugin-format

React 支持

启用 React:

import eonova from '@eonova/eslint-config'

export default eonova({
  react: true
})

安装依赖:

pnpm add -D @eslint-react/eslint-plugin eslint-plugin-react-hooks eslint-plugin-react-refresh

Svelte 支持

启用 Svelte:

import eonova from '@eonova/eslint-config'

export default eonova({
  svelte: true
})

安装依赖:

pnpm add -D eslint-plugin-svelte

(其余框架如 Astro、Solid、UnoCSS 的启用方式类似)

规则覆盖

文件级规则覆盖示例:

// eslint.config.ts
import eonova from '@eonova/eslint-config'

export default eonova({
  files: ['**/*.vue'],
  rules: {
    'vue/operator-linebreak': ['error', 'before']
  }
})

类型感知配置

启用 TypeScript 类型检查:

import eonova from '@eonova/eslint-config'

export default eonova({
  typescript: {
    tsconfigPath: 'tsconfig.json'
  }
})

其他

查看已启用规则

运行命令查看详细规则列表:

npx @eslint/config-inspector

{
  "simple-git-hooks": {
    "pre-commit": "pnpm lint-staged"
  },
  "lint-staged": {
    "*": "eslint --fix"
  }
}
