1. 前言

最近自己学习写了一个基于Vue3的组件库，感觉有点意思，这篇文章来记录一下我是怎么从0快速打造一个UI组件库的

  • 😊先来个预览 jw-ui演示.gif

  • 😘附上访问地址jw-ui

2. 使用Vite搭建官网

Vite是尤雨溪开发的一种新型前端构建工具，具体介绍可以查看官方文档

2.1 创建项目

2.1.1. 全局安装vite（这里我装的时候是2.7.2）

$ yarn create vite@2.7.2

2.1.2. 构建一个vue模板(项目名可以改成自己的名字)

yarn create vite jw-ui --template vue

2.1.3. 装好之后按照提示逐步执行命令

cd jw-ui
yarn
yarn dev

可以看到界面

ps: 推荐的IDE和设置：VSCode + Volar

2.2 基本完成官网的搭建

2.2.1. 下载vue-router

yarn add vue-router@4

2.2.2. 创建home首页与doc文档页 以及顶部导航栏

/* /views/home/index.vue 首页*/
<template>
    <div>
        Home
    </div>
</template>

/* /views/doc/index.vue 文档页面 */
<template>
  <div>
    Doc
  </div>
</template>

/* /components/Topnav.vue 顶部导航栏组件 */
<template>
  <div class="topnav">
    <router-link to="/home">首页</router-link>
    <router-link to="/doc">文档</router-link>
  </div>
</template>

2.2.3. 配置路由

创建路由配置文件

// router/index.ts 
import { createRouter, createWebHashHistory } from "vue-router";
const history = createWebHashHistory();

const router = createRouter({
  history,
  routes: [
    { path: "/", redirect: "" },
  ],
});

export default router;

在main.ts里导入，使得整个应用支持路由。

import { createApp } from "vue";
import App from "./App.vue";
import router from "./router";

const app = createApp(App);
app.use(router);

app.mount("#app");

修改App.vue

<template>
  <Topnav />
  <router-view />
</template>
<script setup>
import Topnav from "./components/Topnav.vue";
</script>

到目前为止的效果

装饰一下顶部导航栏后的效果

这里首页按照自己喜欢的来写CSS就好了，接下来讲一下文档页面。

文档页需要一个侧边栏来切换不同组件的文档，这里我就举例做一个Button组件

// doc/index.vue
<template>
  <div class="layout">
    <div class="content">
      <aside>
        <router-link class="menu-item text-overflow" to="/doc/button"
          >Button 组件</router-link
        >
      </aside>
      <main style="padding-left: 302px">
        <router-view />
      </main>
    </div>
</template>

// router/index.ts 添加一个展示的button页面
import { createRouter, createWebHashHistory } from "vue-router";

import Home from "../views/home/index.vue";
import Doc from "../views/doc/index.vue";
import ButtonDoc from "../views/doc/button/index.vue";

const history = createWebHashHistory();

const router = createRouter({
  history,
  routes: [
    { path: "/", redirect: "/home" },
    { path: "/home", component: Home },
    {
      path: "/doc",
      component: Doc,
      children: [{ path: "button", component: ButtonDoc }],
    },
  ],
});

export default router;


// /views/doc/button/index
<template>
  <Button />
</template>

<script setup>
import Button from '../../../lib/button/index.vue'
</script>

<style lang="scss" scoped>

</style>

展示效果 image.png

好了到这里官网总算是基本搭建完了，我们终于就可以愉快的在src/lib/button/index.vue文件里封装组件啦。（封装的组件都放在lib文件夹里，以后打包用）

3. 封装一个Button组件

下面附上我写的一个Button组件以及使用效果

PS: 需要注意的一点是封装的样式一定要加自己独特的前缀我这里是 jw 以避免在项目中产生样式重叠

<template>
  <button class="jw-button" :class="classes">
    <span v-if="loading" class="jw-loadingIndicator"></span>
    <slot> {{ theme }} </slot>
  </button>
</template>
<script setup lang="ts">
import { computed } from "vue";
const props = defineProps({
  theme: {
    type: String,
    default: "default",
  },
  dashed: {
    type: Boolean,
    default: false,
  },
  size: {
    type: String,
    default: "default",
  },
  round: {
    type: Boolean,
    default: false,
  },
  disabled: {
    type: Boolean,
    default: false,
  },
  loading: {
    type: Boolean,
    default: false,
  },
});

const { theme, dashed, size, round, disabled } = props;
const classes = computed(() => {
  return {
    [`jw-theme-${theme}`]: theme,
    [`jw-theme-dashed`]: dashed,
    [`jw-size-${size}`]: size,
    [`is-round`]: round,
    [`is-disabled`]: disabled,
  };
});
</script>

<script lang="ts">
export default {
  name: "JwButton",
};
</script>

<style lang="scss" scoped>

虽然有不完美，但差不多就这个意思吧👀

4. 封装Markdown组件介绍文档

4.1. 下载

vite-plugin-markdown：一个插件可以让你导入Markdown文件作为各种格式的vite项目。

github-markdown-css：复制GitHub Markdown风格

yarn add github-markdown-css vite-plugin-markdown

4.2. main.ts中引入

import "github-markdown-css";

4.3. vite.config.js中配置vite-plugin-markdown插件

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
const md = require("vite-plugin-markdown");

export default defineConfig({
  plugins: [vue(),
    md.plugin({
    mode: ["html", "vue"],
  }),]
})

4.4. 封装Markdown组件

// /components/Markdown.vue
<template>
  <article class="markdown-body" v-html="content"></article>
</template>

<script setup lang="ts">
// 传入的md文件
const props = defineProps({
  content: {
    type: String,
    required: true,
  },
});
</script>

4.5. 创建介绍页面路由

import { h } from "vue";
import { createRouter, createWebHashHistory } from "vue-router";

import Home from "../views/home/index.vue";
import Doc from "../views/doc/index.vue";
import ButtonDoc from "../views/doc/button/index.vue";

const history = createWebHashHistory();

import Markdown from "../components/Markdown.vue";
const md = (string) => h(Markdown, { content: string, key: string });
import { html as Intro } from "../../markdown/intro.md";
const IntroDoc = md(Intro);

const router = createRouter({
  history,
  routes: [
    { path: "/", redirect: "/home" },
    { path: "/home", component: Home },
    {
      path: "/doc",
      component: Doc,
      children: [
        { path: "intro", component: IntroDoc },
        { path: "button", component: ButtonDoc },
      ],
    },
  ],
});

export default router;

可以看到，最终md就能导入，并且生成了github上md的样式了😁

5. 自定义代码块获取组件展示源代码

5.1. 自定义插件vue-custom-blocks-plugin

import path from "path";
import fs from "fs";
import { baseParse } from "@vue/compiler-core";
const vitePluginVue = {
  name: "preview",
  transform(code, id) {
    if (
      !/\/src\/views\/doc\/.*\.preview\.vue/.test(id) ||
      !/vue&type=preview/.test(id)
    ) {
      return;
    }

    let path = `.${id.match(/\/src\/views\/doc\/.*\.preview\.vue/)[0]}`;
    const file = fs.readFileSync(path).toString();
    const parsed = baseParse(file).children.find((n) => n.tag === "preview");
    const title = parsed.children[0].content;
    const main = file.split(parsed.loc.source).join("").trim();
    return `export default function (Component) {
      Component.__sourceCode = ${JSON.stringify(main)}
      Component.__sourceCodeTitle = ${JSON.stringify(title)}
    }`.trim();
  },
};

export default vitePluginVue;

5.2. 在vite.config.ts中配置

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
const md = require("vite-plugin-markdown");
import vitePluginVue from "./plugins/vue-custom-blocks-plugin";

export default defineConfig({
  plugins: [vue(),
    md.plugin({
    mode: ["html", "vue"],
  }),
  vitePluginVue]
})

5.3. 封装Preview组件展示

<template>
  <div class="pre">
    <h2>
      {{ component.__sourceCodeTitle }}
      <Button @click="hideCode" v-if="codeVisible">隐藏代码</Button>
      <Button @click="showCode" v-else>查看代码</Button>
    </h2>
    <div class="pre-component">
      <component :is="component" />
    </div>

    <div class="pre-code" v-if="codeVisible">
      <pre class="language-html">{{ component__sourceCOde }}</pre>
    </div>
  </div>
</template>

<script setup lang="ts">
import Button from "../lib/button/index.vue";
import { computed, ref } from "vue";
const props = defineProps({
  component: Object,
});

const showCode = () => (codeVisible.value = true);
const hideCode = () => (codeVisible.value = false);
const codeVisible = ref(false);
</script>

<style lang="scss" scoped>
$border-color: #d9d9d9;

.pre {
  border: 1px solid $border-color;
  margin: 16px 0px 32px;
  max-width: 700px;
  min-width: 300px;
  > h2 {
    font-size: 20px;
    padding: 8px 16px;
    border-bottom: 1px solid $border-color;
    display: flex;
    justify-content: space-between;
  }

  &-component {
    padding: 16px;
  }

  &-actions {
    padding: 8px 16px;
    border-top: 1px dashed $border-color;
  }

  &-code {
    padding: 8px 16px;
    border-top: 1px dashed $border-color;

    > pre {
      line-height: 1.1;
      font-family: Consolas, "Courier New", Courier, monospace;
      margin: 0;
      background-color: #fff;
    }
  }
}
</style>

5.4. 使用Preview组件

views/doc/button/index.vue

<template>
  <div>
    <Preview :component="Button1" />
  </div>
</template>

<script setup>
import Button1 from "./Button1.preview.vue";
import Preview from "../../../components/Preview.vue";
</script>

<style lang="scss">
.jw-button + .jw-button {
  margin-left: 20px;
}
</style>

/views/doc/button/Button1.preview.vue

<preview>基础示例</preview>
<template>
  <Button />
</template>

<script setup lang="ts">
import Button from "../../../lib/button/index.vue";
</script>

现在，只要编写上面的以.preview.vue后缀的文件就行了。

  • 效果：

image.png

5.5. 高亮源代码

下载prismjs

yarn add prismjs

对Preview组件做修改

<template>
  <div class="pre">
    <h2>
      {{ component.__sourceCodeTitle }}
      <Button @click="hideCode" v-if="codeVisible">隐藏代码</Button>
      <Button @click="showCode" v-else>查看代码</Button>
    </h2>
    <div class="pre-component">
      <component :is="component" />
    </div>

    <div class="pre-code" v-if="codeVisible">
      <pre class="language-html" v-html="html" />
    </div>
  </div>
</template>
<script setup lang="ts">
import Button from "../lib/button/index.vue";
import { computed, ref } from "vue";
import "prismjs";
import "prismjs/themes/prism.css";
const Prism = (window as any).Prism;
const props = defineProps({
  component: Object,
});

console.log(props.component.__sourceCode);
const html = computed(() => {
  return Prism.highlight(
    props.component.__sourceCode,
    Prism.languages.html,
    "html"
  );
});
const showCode = () => (codeVisible.value = true);
const hideCode = () => (codeVisible.value = false);
const codeVisible = ref(false);
</script>
  • 效果

6. 去掉示例中的文件导入

image.png

6.1. 在lib目录下创建main.ts 这个也是作为之后打包上传至npm的入口

import { App } from "vue";
import JwButton from "./button/index.vue";
export {  JwButton };
const components = [JwButton];

// 全局注册主键
export function registerJwUi(app: App): void {
  for (const component of components) {
    app.component(component.name, component);
  }
}

export default registerJwUi;

6.2. main.ts中导入注册

import JwUi from "./lib/index";
app.use(JwUi);

6.3. 这样在示例中就可以直接用了/src/views/doc/button/Button1.preview

<preview>基础示例</preview>
<template>
  <jw-button />
</template>

6.4. 效果

7. 部署到github官网

7.1. 打包

yarn build

7.2. 上传至github

github创建一个新的仓库 将dist上传只仓库

7.3. 进入仓库Settings最底层

image.png

7.4. 找到GitHub Pages

image.png

7.5. 选择master分支 点击保存 链接就生成了

image.png

7.6 一键部署

创建deploy.sh文件

rm -rf dist &&
yarn build &&
cd dist &&
git init &&
git add . &&
git commit -m "update" &&
git branch -M master &&
git remote add origin git@github.com:coderyjw/jw-ui-website.git &&
git push -f -u origin master &&
cd -
echo https://coderyjw.github.io/jw-ui-website/

执行命令

sh deploy.sh

8. 上传至npm

8.1. 创建rollup.config.js配置文件

// 为了保证版本一致，请复制我的 package.json 到你的项目，并把 name 改成你的库名
import esbuild from 'rollup-plugin-esbuild'
import vue from 'rollup-plugin-vue'
import scss from 'rollup-plugin-scss'
import dartSass from 'sass';
import { terser } from "rollup-plugin-terser"
import alias from '@rollup/plugin-alias'
import path from "path";
import resolve from 'rollup-plugin-node-resolve'

export default {
  input: 'src/lib/index.ts',
  output: [{
    globals: {
