官方脚手架 Vue CLI 项目的配置
在 2020 年 2 月在创建项目脚手架中升级 Vue CLI 4.2 之后,通过使用全局 vue create myproject 命令创建一个新项目并至少进行这些选择(包括的配置),您已完成配置的一半下面):
Vue CLI v4.2.2
? Please pick a preset: Manually select features
? Check the features needed for your project:
(*) Babel
(*) TypeScript
( ) Progressive Web App (PWA) Support
( ) Router
( ) Vuex
(*) CSS Pre-processors
>(*) Linter / Formatter
( ) Unit Testing
( ) E2E Testing
? Use Babel alongside TypeScript (required for modern mode, auto-detected polyfills, transpiling JSX)? (Y/n) Y
? Pick a CSS pre-processor (PostCSS, Autoprefixer and CSS Modules are supported by default):
Sass/SCSS (with dart-sass)
> Sass/SCSS (with node-sass)
Less
Stylus
? Pick a linter / formatter config:
ESLint with error prevention only
> ESLint + Airbnb config
ESLint + Standard config
ESLint + Prettier
TSLint (deprecated)
? Pick additional lint features: (Press <space> to select, <a> to toggle all, <i> to invert selection)
>(*) Lint on save
( ) Lint and fix on commit
? Where do you prefer placing config for Babel, ESLint, etc.? (Use arrow keys)
> In dedicated config files
In package.json
现在您可能想知道为什么我选择node-sass 而不是第一个建议选项dart-sass - 原因如下:Vue CLI CSS pre-processor option: dart-sass VS node-sass?
在package.json 中,您至少获得了这些依赖项:
"dependencies": {
"core-js": "^3.6.4",
"vue": "^2.6.11"
},
"devDependencies": {
"@typescript-eslint/eslint-plugin": "^2.18.0",
"@typescript-eslint/parser": "^2.18.0",
"@vue/cli-plugin-babel": "~4.2.0",
"@vue/cli-plugin-eslint": "~4.2.0",
"@vue/cli-plugin-typescript": "~4.2.0",
"@vue/cli-service": "~4.2.0",
"@vue/eslint-config-airbnb": "^5.0.2",
"@vue/eslint-config-typescript": "^5.0.1",
"eslint": "^6.7.2",
"eslint-plugin-import": "^2.20.1",
"eslint-plugin-vue": "^6.1.2",
"node-sass": "^4.12.0",
"sass-loader": "^8.0.2",
"typescript": "~3.7.5",
"vue-template-compiler": "^2.6.11"
}
.eslintrc.js:
module.exports = {
root: true,
env: {
node: true,
},
extends: [
'plugin:vue/essential',
'@vue/airbnb',
'@vue/typescript/recommended',
],
parserOptions: {
ecmaVersion: 2020,
},
rules: {
'no-console': process.env.NODE_ENV === 'production' ? 'error' : 'off',
'no-debugger': process.env.NODE_ENV === 'production' ? 'error' : 'off',
},
};
与.editorconfig:
[*.{js,jsx,ts,tsx,vue}]
indent_style = space
indent_size = 2
end_of_line = lf
trim_trailing_whitespace = true
insert_final_newline = true
max_line_length = 100
用于 linting 和格式化的有偏见的配置更改
因此,我对.eslintrc.js 进行了偏颇的修改:
module.exports = {
root: true,
env: {
node: true,
},
extends: [
'plugin:vue/recommended',
'@vue/airbnb',
'@vue/typescript/recommended',
],
parserOptions: {
ecmaVersion: 2020,
},
rules: {
'class-methods-use-this': 0,
// Changing max row length from 80 to 150.
// Remember to change in .editorconfig also, although am not sure if that file is even needed?
// Especially as scaffolding gave 100 as max len while ESLint default is 80...
'max-len': [
'error',
{
code: 150,
ignoreComments: true,
ignoreUrls: true,
},
],
'no-console': process.env.NODE_ENV === 'production' ? 'error' : 'off',
'no-debugger': process.env.NODE_ENV === 'production' ? 'error' : 'off',
'@typescript-eslint/ban-ts-ignore': 0,
},
// These are added if you chose also to install Jest plugin for Vue CLI
// With my own modifications here as an example
overrides: [
{
files: [
'./src/**/__tests__/*.spec.{j,t}s',
'./src/**/__mock__/*.{j,t}s',
],
env: {
jest: true,
},
rules: {
'no-unused-expressions': 0,
},
},
],
};
然后我添加了.eslintignore 文件:
# Lint config files in the root ending .js
!/*.js
然后我在.editorconfig 顶部添加了这个部分(虽然不确定是否需要这个文件):
# EditorConfig is awesome: https://EditorConfig.org
# top-most EditorConfig file
root = true
安装和配置 Stylelint
Stylelint 是一个类似于 CSS/SCSS/SASS/LESS/Stylus 的项目,而不是用于 JavaScript/TypeScript 的 ESLint,同样可以通过插件和预设进行扩展。它有一个官方的 VS Code 扩展,也可以在你的 Webpack 构建过程中运行。
我选择使用 stylelint-scss package 扩展 Stylelint,目前每周有 50 万次下载,stylelint-config-recommended-scss package 来自同一维护者。此外,我已将 stylelint-webpack-plugin 配置为 Webpack 构建过程的一部分。
通过以下方式从命令行安装这些开发依赖项:npm i -D stylelint stylelint-config-recommended-scss stylelint-scss stylelint-webpack-plugin
添加一个文件.stylelintrc.json,并以一些有偏见的规则修改为例(可能需要Vue的::v-deep自定义选择器处理):
{
"extends": "stylelint-config-recommended-scss",
"rules": {
"max-nesting-depth": 4,
"no-descending-specificity": null,
"property-no-unknown": [
true,
{
"ignoreProperties": ["user-drag", "font-smooth"]
}
],
"selector-pseudo-element-no-unknown": [
true,
{
"ignorePseudoElements": ["v-deep"]
}
]
}
}
创建文件或添加到vue.config.js,这是一些有偏见的配置示例:
// Add in the top of the file
const StyleLintPlugin = require('stylelint-webpack-plugin');
module.exports = {
css: {
loaderOptions: {
sass: {
// Here as example if needed:
// Import Sass vars and mixins for SFC's style blocks
prependData: '@import "@/assets/styles/abstracts/_variables.scss"; @import "@/assets/styles/abstracts/_mixins.scss";',
},
},
},
lintOnSave: process.env.NODE_ENV !== 'production',
productionSourceMap: false,
devServer: {
overlay: {
warnings: true,
errors: true,
},
},
configureWebpack: {
// Fast source maps in dev
devtool: process.env.NODE_ENV === 'production' ? false : 'cheap-eval-source-map',
plugins: [
new StyleLintPlugin({
files: 'src/**/*.{vue,scss}',
}),
],
resolve: {
alias: {
// Alias @ to /src folder for ES/TS imports
'@': path.join(__dirname, '/src'),
},
},
},
};
VS Code 编辑器、扩展和设置
在项目根目录中创建 .vscode 命名文件夹,用于放置项目特定设置和扩展建议。请注意,如果您在工作区模式下打开 VS Code(一次包含多个项目根目录),某些设置在此模式下不起作用,所以我总是直接打开项目根目录而不使用工作区模式。
在这个文件夹中添加一个文件extensions.json,至少推荐这个内容,然后安装扩展。
{
"recommendations": [
// ESLint - Integrates ESLint JavaScript into VS Code.
"dbaeumer.vscode-eslint",
// Disable eslint rule - Disable eslint rule with one click.
"wooodhead.disable-eslint-rule",
// eslint-disable-snippets - Simple snippets for disable eslint rules
"drknoxy.eslint-disable-snippets",
// Vue - Syntax highlight for Vue.js
"jcbuisson.vue",
// stylelint - Modern CSS/SCSS/Less linter
"stylelint.vscode-stylelint",
// EditorConfig for VS Code - EditorConfig Support for Visual Studio Code
// Not sure if this is needed or recommended,
// but .editorconfig file is still included in the scaffolded project...
"editorconfig.editorconfig",
// DotENV - Support for dotenv file syntax.
"mikestead.dotenv",
]
}
使用这些或类似设置添加另一个文件settings.json:
{
// EDITOR
// ----------------------------------------
"editor.defaultFormatter": "dbaeumer.vscode-eslint",
"[javascript]": { "editor.defaultFormatter": "dbaeumer.vscode-eslint" },
"[typescript]": { "editor.defaultFormatter": "dbaeumer.vscode-eslint" },
"[vue]": { "editor.defaultFormatter": "dbaeumer.vscode-eslint" },
"[scss]": { "editor.defaultFormatter": "stylelint.vscode-stylelint" },
"[css]": { "editor.defaultFormatter": "stylelint.vscode-stylelint" },
"editor.codeActionsOnSave": {
// https://github.com/microsoft/vscode-eslint/blob/master/README.md#release-notes
"source.fixAll.eslint": true,
"source.fixAll.stylelint": true
},
// ESLINT
// ----------------------------------------
"eslint.enable": true,
"eslint.alwaysShowStatus": true,
"eslint.options": {
"extensions": [".html", ".js", ".ts", ".vue"]
},
// VETUR
// Disable rules if user has extension installed and enabled.
// ----------------------------------------
"vetur.validation.template": false,
"vetur.validation.style": false,
"vetur.format.defaultFormatter.html": "none",
"vetur.format.defaultFormatter.css": "none",
"vetur.format.defaultFormatter.scss": "none",
"vetur.format.defaultFormatter.js": "none",
"vetur.format.defaultFormatter.ts": "none",
// STYLELINT
// ----------------------------------------
"stylelint.enable": true,
"css.validate": true,
"scss.validate": true,
// HTML
// ----------------------------------------
"html.format.enable": false,
"emmet.triggerExpansionOnTab": true,
"emmet.includeLanguages": {
"vue-html": "html"
},
// FILES
// ----------------------------------------
"files.exclude": {
"**/*.log": true,
"**/*.log*": true,
"**/dist": true,
},
"files.associations": {
".babelrc": "jsonc",
".eslintrc": "jsonc",
".markdownlintrc": "jsonc",
"*.config.js": "javascript",
"*.spec.js": "javascript",
"*.vue": "vue"
},
// The default end of line character. Use \n for LF and \r\n for CRLF.
"files.eol": "\n",
"files.insertFinalNewline": true,
"files.trimFinalNewlines": true,
"files.trimTrailingWhitespace": true,
}
所以这些是我有偏见的项目设置,我有兴趣听取改进建议!
