背景：为了避免重复造轮子，很有必要开发一个通用组件库，方便重复利用。本文是采用 vue-lic3.0 脚手改造而成的，使用 vuepress 作为演示环境。
首先通过 vue 脚手架生产目录如下：
然后我们需要修改一下：删除 public 目录，添加 packages，utils 和 lib 文件，见如下：
packages 是用于放控件库，utils 是用于放一些通用工具（方法等），src 用于整个控件的引用，lib 用于放打包后的文件：src 下放如下内容
index.js 是将所有控件引入，作为打包的入口
import locale from ‘hui-pro/src/locale’; // 语言包
import ‘hui-pro/packages/theme/index.scss’; // 皮肤包，将主题抽离出来
const components = [] // 放控件库
const install = function(Vue, opts = {}) {
/* istanbul ignore if */
if (install.installed) return;
locale.use(opts.locale);
locale.i18n(opts.i18n);
components.map(component => {
Vue.component(component.name, component);
});
Vue.use(EllipsisDirective);
};
/* istanbul ignore if */
if (typeof window !== ‘undefined’ && window.Vue) {
install(window.Vue);
}
export default {
version: ‘0.1.0’,
locale: locale.use,
i18n: locale.i18n,
install,
… // 控件
}
src 下 locale 是用于管理多语言的，我们在开发控件的时候是不能讲中文写死，所以需要做一层多语言处理，而单纯的控件库有是没有引入 vue 实例，那就更不用说 i18n 了，所以这边就是通过自己翻译，引用项目工程中的 i18n 或者直接自己做切割翻译。如下：index.js
import defaultLang from ‘hui-pro/src/locale/lang/zh-CN’;
import Vue from ‘vue’;
import deepmerge from ‘deepmerge’;
import Format from ‘./format’;
const format = Format(Vue);
let lang = defaultLang;
let merged = false;
let i18nHandler = function() {
const vuei18n = Object.getPrototypeOf(this || Vue).$t;
if (typeof vuei18n === ‘function’ && !!Vue.locale) {
if (!merged) {
merged = true;
Vue.locale(
Vue.config.lang,
deepmerge(lang, Vue.locale(Vue.config.lang) || {}, { clone: true})
);
}
return vuei18n.apply(this, arguments);
}
};
export const t = function(path, options) {
let value = i18nHandler.apply(this, arguments);
if (value !== null && value !== undefined) return value;
const array = path.split(‘.’);
let current = lang;
for (let i = 0, j = array.length; i < j; i++) {
const property = array[i];
value = current[property];
if (i === j – 1) return format(value, options);
if (!value) return ”;
current = value;
}
return ”;
};
export const use = function(l) {
lang = l || lang;
};
export const i18n = function(fn) {
i18nHandler = fn || i18nHandler;
};
export default {use, t, i18n};
format.js 这个是通过自己本地切割字符串来找对应的翻译：‘xxx.yyy.ccc’ => xxx: {yyy: {ccc: ‘ 翻译次 ’}}
const RE_NARGS = /(%|)\{([0-9a-zA-Z_]+)\}/g;
/**
* String format template
* – Inspired:
* https://github.com/Matt-Esch/string-template/index.js
*/
export default function() {
/**
* template
*
* @param {String} string
* @param {Array} …args
* @return {String}
*/
function template(string, …args) {
if (args.length === 1 && typeof args[0] === ‘object’) {
args = args[0];
}
if (!args || !args.hasOwnProperty) {
args = {};
}
return string.replace(RE_NARGS, (match, prefix, i, index) => {
let result;
if (string[index – 1] === ‘{‘ && string[index + match.length] === ‘}’) {
return i;
} else {
result = Object.prototype.hasOwnProperty.call(args, i) ? args[i] : null;
if (result === null || result === undefined) {
return ”;
}
return result;
}
});
}
return template;
}
然后在 mixins 中加入一个使用多语言的方法，主要是这个方法是一样的，所以提取到 mixinsmixins/locale.js
import {t} from ‘hui-pro/src/locale’;
export default {
methods: {
t(…args) {
return t.apply(this, args);
}
}
};
之后控件库中可以直接引用 mixis，t(), this.t() 的形式使用了
import Locale from ‘hui-pro/src/mixins/locale’;
mixins: [Locale]
使用
html 中
{{t(‘aa.bb’)}}
js 中使用
test () {
this.t(‘aa.bb’)
}
接下来我们还需要修改一些配置：babel.config.js
const utilTypeList = []// 对外暴露工具库的列表
module.exports = function(api) {
let presets = [‘@vue/app’];
let plugins = [];
if (api.env(‘js’)) {
presets = [[‘@babel/preset-env’, { loose: true}]];
plugins = [
[
‘module-resolver’,
{
root: [‘hui-pro’],
alias: {
‘hui-pro/src’: ‘hui-pro/lib’
}
}
]
];
} else if (api.env(‘node’)) {
presets = [
[
‘@babel/preset-env’,
{
targets: {
node: true
}
}
]
];
}
// 按需加载 utils
for (let type of utilTypeList) {
plugins.push([
‘import’,
{
libraryName: `hui-pro/packages/utils/${type}`,
libraryDirectory: ”
},
`${type}`
]);
}
return {
presets,
plugins
};
};
需要安装 eslintrc.js 增加配置文件
var isDev = process.env.NODE_ENV === ‘development’;
module.exports = {
root: true,
env: {
mocha: true,
es6: true,
node: true,
browser: true
},
parserOptions: {
parser: ‘babel-eslint’
},
plugins: [‘vue’],
extends: [‘plugin:vue/strongly-recommended’, ‘@vue/prettier’],
rules: {
‘vue/html-indent’: 1,
‘no-console’: isDev
? 0
: [
‘error’,
{
allow: [‘warn’, ‘error’]
}
],
‘no-debugger’: isDev ? 0 : 2
},
globals: {
expect: true,
sinon: true
}
};
还需要增加 stylelintrc 效验
{
“plugins”: [“stylelint-prettier”, “stylelint-scss”],
“extends”: [
“stylelint-config-idiomatic-order”,
“stylelint-config-standard”,
“stylelint-config-prettier”
],
“rules”: {
“at-rule-no-unknown”: null,
“scss/at-rule-no-unknown”: true,
“prettier/prettier”: true
}
}
最后增加一下 vue 的配置
const path = require(‘path’);
const nodeExternals = require(‘webpack-node-externals’);
module.exports = {
publicPath: ”,
outputDir: ‘lib’,
assetsDir: ”,
filenameHashing: false,
css: {
extract: true,
sourceMap: false
},
productionSourceMap: false,
pages: {
index: {
// page 的入口
entry: ‘preview/main.js’,
// 模板来源
template: ‘preview/index.html’
}
},
devServer: {
port: 8999
},
configureWebpack() {
if (process.env.LIB_TYPE === ‘common’) {
return {
externals: [
{
vue: ‘vue’,
‘hui-pro/src/locale’: ‘hui-pro/lib/locale’
},
nodeExternals()
]
};
}
},
chainWebpack(webpackConfig) {
webpackConfig.when(process.env.LIB_TYPE === ‘umd’, config => {
config.output.umdNamedDefine(true);
});
webpackConfig.resolve.alias.set(‘hui-pro’, path.resolve(__dirname));
//svg
const svgRule = webpackConfig.module.rule(‘svg’);
svgRule.uses.clear();
svgRule
.oneOf(‘svg’)
.resourceQuery(/svg/)
.use(‘vue-svg-loader’)
.loader(‘vue-svg-loader’)
.end()
.end()
.oneOf(‘img’)
.resourceQuery(/img/)
.use(‘url-loader’)
.loader(‘url-loader’)
.options({
name: ‘img/[name].[hash:8].[ext]’
})
.end()
.end()
.oneOf()
.use(‘file-loader’)
.loader(‘file-loader’)
.options({
name: ‘fonts/[name].[ext]’
});
webpackConfig.module
.rule(‘fonts’)
.use(‘url-loader’)
.tap(options => Object.assign(options, { limit: 10}));
// map-picker 控件中，map/ 下的代码是 openlayer 相关代码，无需 babel 编译。
webpackConfig.module
.rule(‘js’)
.test(/\.js$/)
.exclude.add(path.resolve(__dirname) + ‘packages/map-picker/src/map’)
.end()
.use(‘babel-loader’);
//stylelint
webpackConfig
.plugin(‘stylelint’)
.use(‘stylelint-webpack-plugin’)
.tap(() => {
return [
{
configFile: ‘.stylelintrc’,
files: [‘packages/**/*.scss’],
emitErrors: true
}
];
});
}
};
当然如果使用 git 的话，使用 commitlint 来效验提交的代码
{
“printWidth”: 80,
“tabWidth”: 2,
“singleQuote”: true,
“trailingComma”: “none”,
“bracketSpacing”: true,
“semi”: true,
“useTabs”: false,
“proseWrap”: “never”,
“overrides”: [
{
“files”: [
“*.json”,
“.eslintrc”,
“.babelrc”,
“.stylelintrc”,
“.prettierrc”
],
“options”: {
“parser”: “json”,
“tabWidth”: 2
}
}
]
}
最后，需要修改 package.json
{

“version”: “0.1.0-alpha.1”,

“lint”: “vue-cli-service lint packages src && stylelint packages/**/*.scss –fix”,
