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 🙏

eslint-config-rc

v2.0.2

Published

标准化的一个eslint-config配置方案

Readme

eslint-config-rc

  1. 支持 TypeScriptJavaScript
  2. 自动格式化代码,无需手动
  3. script 脚本支持 lint 和 lint-fix 两个命令

安装

eslint 插件安装

$ npm install eslint-config-rc eslint --save--dev 

git-pre-hooks 安装

$ npm install git-pre-hooks --save-dev

eslint-formatter-pretty 插件安装(将eslint错误显示到终端)

$ npm install eslint-formatter-pretty --save-dev

配置

vscode settings.json 添加以下配置(保存会自动按照eslint格式化)

"editor.codeActionsOnSave": {
  "source.fixAll.eslint": true,
},
"eslint.format.enable": true,
"eslint.validate": [
    "javascript",
    "javascriptreact",
    "vue",
    "html",
    "typescript",
    "typescriptreact"
],

package.json 添加以下配置(commit的时候触发检测钩子)

"scripts": {
  "lint": "eslint src --ext .js,.jsx,.ts,.tsx",
  "lint-fix": "eslint src --ext .js,.jsx,.ts,.tsx --fix --cache"
},
"git-pre-hooks": {
  "pre-commit": "npm run lint"
}

webpack 添加以下配置(注意loader放置顺序)

// js使用
const eslintFormatterPretty = require('eslint-formatter-pretty');
rules: [{
  test: /\.(js|jsx|ts|tsx)$/,
  loader: 'eslint-loader',
  exclude: /(node_modules)/,
  include: path.resolve(__dirname, '../src'), // 精确指定要处理的目录
  options: {
    formatter: eslintFormatterPretty,
    emitError: true,
    failOnError: true
  }
}],
// ts使用
const ForkTsCheckerWebpackPlugin = require('fork-ts-checker-webpack-plugin');
plugins: [
  new ForkTsCheckerWebpackPlugin({
    tsconfig: path.resolve(__dirname, '../tsconfig.json'),
    async: false,
    silent: true,
    eslint: true,
  }),
]

修改devServer overlay属性 不然eslint报错会阻塞代码编译.

devServer: {
  overlay: false, // 不在浏览器页面上显示错误
}

使用

JavaScript

  • 根目录创建 .eslintrc.js 写入一下配置
module.exports = {
  extends: 'eslint-config-rc',
};
  • 根目录创建 .eslintignore
/node_modules/ //忽略xxxx文件

TypeScript

  • 根目录创建 .eslintrc.js 写入一下配置
module.exports = {
  extends: 'eslint-config-rc/typescript',
  parserOptions: {
    project: './tsconfig.json', // tsconfig配置看个人
  },
};
  • 根目录创建 .eslintignore
/node_modules/ // 忽略xxxx文件
