vue3.2从0-1封装一个组件库

1：组件的项目初建

1-1创建项目

• npm init vue@latest
• 目录文件
  

1-2 packages / button / index.js

// @ts-nocheck
import tButton from "./index.vue";
tButton.install = (app) => {
  app.component(tButton.name, tButton);
};
export default tButton;

1-3 packages / button / index.vue

<!-- -->
<template>
  <div>
    <button><slot /></button>
  </div>
</template>
<script>
export default {
  name: 'tButton'
}
</script>
<script setup></script>
<style lang="scss" scoped></style>

1-4 packages / index.js

import tButton from "./button/index.js";

const install = (app) => {
  app.use(tButton);
};
const TUI = {
  install,
};
// 按需引入 import { tButton } from "TUI"
export {
  tButton
};
export default TUI;

1-5 使用 组件 - App.vue

<!-- App -->
<template>
  <div>
    App

    <t-button>我是按钮</t-button>
  </div>
</template>

<script setup lang="ts" name="App">
// import tButton from "../packages/button/index.vue";
import {} from "vue";
</script>
<style lang="scss" scoped></style>

1-6 package.json

{
  "name": "vue-ui",
  "version": "0.0.1",
  "private": "false",
  "main": "./dist/vue-ui.mjs",
  "module": "./dist/vue-ui.umd.js",
  "exports": {
    ".": {
      "import": "./dist/vue-ui.mjs",
      "require": "./dist/vue-ui.umd.js"
    }
  },
  "files": ["dist/*"],
}

1-7 main.js

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

import "./assets/main.css";

import TUI from "../packages/index";

const app = createApp(App);
app.use(TUI);
app.mount("#app");

1-7 vite.config.ts 配置打包的入口

import {
  defineConfig
} from 'vite'
import vue from '@vitejs/plugin-vue'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  build: {
    rollupOptions: {
      external: ["vue"],
      output: {
        globals: {
          vue: "Vue"
        }
      }
    },
    lib: {
      // 打包的入口
      entry: "./packages/index.js",
      name: "xzl-vue-ui",
    },
  },
})

2：组件库 之 button组件

2-1 packages / button / index.vue

<!-- -->
<template>
  <div :class="tClass">
    <button><slot /></button>
  </div>
</template>
<script lang="ts">
export default {
  name: 'tButton'
}
</script>
<script setup lang="ts">
import { computed } from 'vue'
type Props = {
  type?: string
}
const props = withDefaults(defineProps<Props>(), {
  type: 'default'
})
console.log('props', props.type)
const tClass = computed(() => {
  return ['t-button', `t-button-${props.type}`]
})
</script>

<style lang="scss" scoped>
button {
  outline: none;
  border: 0;
  background: none;
  cursor: pointer;
}
.t-button {
  button {
    padding: 12px 20px;
    border: 1px solid #ccc;
    border-radius: 4px;
    &:hover,
    &:focus {
      opacity: 0.7;
    }
  }
}
.t-button-default {
  button {
    background: #b4b0b0;
    color: #000;
  }
}
.t-button-success {
  button {
    background: #0eac77;
    color: #fff;
  }
}
.t-button-warning {
  button {
    background: red;
    color: #fff;
  }
}
</style>

2-2 使用 button 组件

    <tButton>按钮1</tButton>
    <tButton type="success">按钮</tButton>
    <tButton type="warning">按钮</tButton>

效果

3：组件库 之 input组件

3-1 packages / input / index.js

<!-- 简单的input组件 -->
<template>
  <div>
    <input :type="tType" :value="modelValue" @input="input" />
  </div>
</template>
<script lang="ts">
export default {
  name: 'tInput'
}
</script>
<script setup lang="ts" name="tInput">
import { computed } from 'vue'
const props = withDefaults(
  defineProps<{
    type?: string
    modelValue?: string | number
  }>(),
  {
    type: 'text',
    modelValue: ''
  }
)
const emit = defineEmits(['update:modelValue'])
const tType = computed(() => {
  return props.type
})
const input = event => {
  emit('update:modelValue', event.target.value)
}
</script>
<style lang="scss" scoped></style>

3-2 使用 input 组件

<!-- -->
<template>
  <div>
    inpVal - {{ inpVal }}
    <tInput v-model="inpVal"></tInput>
    <tInput type="password"></tInput>
  </div>
</template>
<script setup name="App">
// import tBB from '../packages/button/index'
import { ref } from 'vue'
const inpVal = ref('')
</script>
<style lang="scss" scoped></style>

3-3效果

2：发布npm 组件库

切换npm 镜像

npm get registry 
npm config set registry https://registry.npmjs.org/
npm config set registry https://registry.npm.taobao.org/

• npm 登录
  
• npm 发布 npm publish
• 注意点：就是执行 npm publish之前，需要先 npm run build打包后才可
• npm publish发布效果
  
• npm之中 查找 ``xzl-vue-ui 即可
• 安装以及使用

npm i xzl-vue-ui

main.js 文件之中 使用
import "./assets/main.css";
import TUI from "xzl-vue-ui"
const app = createApp(App);
app.use(TUI);
app.mount("#app");
