@mega-apps/vue-addon-loader

Vue 扩展加载器，适用于动态加载 Vue 组件。

Vue Addon Loader is a small library that allows you to load Vue components from a module dynamically. It's only dependent on the vue runtime. no need to install any other dependencies. No node.js or webpack dependencies.

1. 主要特性

  • 完全支持 Vue2 的组件
  • 可支持IE11版本
  • 仅需要Vue运行时，无需其他依赖
  • 提供 esm and umd 包
  • 支持 JSX 语法
  • 支持 嵌入ES6模块写法
  • 支持自定义 CSS、HTML、脚本支持
  • 支持 SFC 自定义模块
  • 支持编译错误定位
  • 支持远程组件，来源于网络、数据库、本地文件... 等

安装

# yarn 安装
yarn add @mega-apps/vue-addon-loader

# 或 pnpm 安装
pnpm add @mega-apps/vue-addon-loader

简单示例
