Detailed explanation of the use of mobile component library cube-ui

This time I will bring you a detailed explanation of the use of the mobile component library cube-ui. What are the precautions when using the mobile component library cube-ui? The following is a practical case, let's take a look.

cube-ui is an exquisite mobile component library implemented by Didi's technical team based on Vue.js. It's great. Although there are not many components, it is enough for basic scenarios. Thanks for the open source!

First create a vue project

vue init webpack my-project
cd my-project
npm install

Install cube-ui

npm install cube-ui -S

The official recommendation is to use the babel-plugin-transform-modules plug-in, which can introduce component modules and corresponding styles more elegantly.

npm install babel-plugin-transform-modules -D

Then configure this plugin and modify .babelrc: (add to plugins)

{
 "plugins": [
 ["transform-modules", {
  "cube-ui": {
  "transform": "cube-ui/lib/${member}",
  "kebabCase": true,
  "style": {
   "ignore": ["create-api", "better-scroll"]
  }
  }
 }]
 ]
}

Introduction method 1: Import all

Generally in entry filemain.js:

import Vue from 'vue'
import Cube from 'cube-ui' // 一般直接放在这个位置
Vue.use(Cube)

After all are introduced, it is equivalent to global registration, and you can use it directly. There is no need to import { ... } (local reference ) in each .vue file, and components{ ... } are locally registered.

Introduction method 2: On-demand introduction

import {
 /* eslint-disable no-unused-vars */
 Style, // 必需
 Button
} from 'cube-ui'

Note: If imported on demand, the basic style part will not be packaged, so you need to introduce the style module when using it.

Registration method You can choose global registration or local registration:

// 全局注册
Vue.use(Button) // 在入口文件中
// 或者局部注册
// 某个组件中
{
 components: {
 CubeButton: Button
 }
}

All components that can be imported on demand:

import {
 Button,
 Checkbox,
 Loading,
 Tip,
 Toast,
 Picker,
 TimePicker,
 Dialog,
 ActionSheet,
 Scroll,
 Slide,
 IndexList
} from 'cube-ui'

You can also introduce create-api and better-scroll modules:

import { createAPI, BetterScroll } from 'cube-ui'

Example

Do not use post-compile

Note: cube-ui with webpack 2 will use post-compilation by default, but post-compilation requires some dependencies and configurations (see the end of this page); if you don’t want to use post-compilation, you can directly modify the webpack configuration:

// webpack.config.js
module.exports = {
 // ...
 resolve: {
 // ...
 alias: {
  // ...
  'cube-ui': 'cube-ui/lib'
  // ...
 }
 // ...
 }
 // ...
}

Compile after use

When cube-ui is paired with webpack 2, post-compile will be used by default, so the application needs to be compatible with cube-ui's dependencies and configuration.

1. Modify package.json

{
 // webpack-post-compile-plugin 依赖 compileDependencies
 "compileDependencies": ["cube-ui"],
 "devDependencies": {
 "babel-plugin-transform-modules": "^0.0.2",
 // 新增 stylus 相关依赖 (都需要额外安装：npm install … -D)
 // stylus 类似于 sass,less
 "stylus": "^0.54.5",
 "stylus-loader": "^2.1.1",
 "webpack-post-compile-plugin": "^0.1.2"
 }
}

2. Modify .babelrc and still rely on babel-plugin-transform-modules:

"plugins": [
 ["transform-runtime"],
 ["transform-modules", {
 "cube-ui": {
  // 注意: 这里的路径需要修改到 src/modules 下
  "transform": "./node_modules/cube-ui/src/modules/${member}",
  "kebabCase": true
 }
 }]
]

3. Modify webpack.base.conf.js

var PostCompilePlugin = require('webpack-post-compile-plugin')
module.exports = {
 // ...
 plugins: [
 // ...
 new PostCompilePlugin()
 ]
 // ...
}

4. Modify the exports.cssLoaders function in build/utils.js

exports.cssLoaders = function (options) {
 // ...
 const stylusOptions = {
 'resolve url': true
 }
 // https://vue-loader.vuejs.org/en/configurations/extract-css.html
 return {
 css: generateLoaders(),
 postcss: generateLoaders(),
 less: generateLoaders('less'),
 sass: generateLoaders('sass', { indentedSyntax: true }),
 scss: generateLoaders('sass'),
 stylus: generateLoaders('stylus', stylusOptions),
 styl: generateLoaders('stylus', stylusOptions)
 }
}
