-## ✨ 特性
-
-- 🌈 提炼自企业级低代码平台的面向扩展设计的内核引擎，奉行最小内核，最强生态的设计理念
-- 📦 开箱即用的高质量生态元素，包括 物料体系、设置器、插件 等
-- ⚙️ 完善的工具链，支持 物料体系、设置器、插件 等生态元素的全链路研发周期
-- 🔌 强大的扩展能力，已支撑近 100 个各种垂直类低代码平台
-- 🛡 使用 TypeScript 开发，提供完整的类型定义文件
-
-## 🎯 兼容环境
-
-- 现代浏览器（Chrome >= 80, Edge >= 80, last 2 safari versions, last 2 firefox versions）
-
-## 📚 引擎协议
-
-引擎完整实现了《阿里巴巴中后台前端基础搭建协议规范》和《阿里巴巴中后台前端物料协议规范》，协议栈是低代码领域的物料能否流通的关键部分。
-
-
-
-## 🌰 使用示例
-
-```bash
-npm install @alilc/lowcode-engine --save-dev
-```
-
-> **TIPS：仅支持 cdn 方式引入，npm 包用于提供 typings 等代码提示能力**
-
-```ts
-import { init, skeleton } from '@alilc/lowcode-engine';
-
-skeleton.add({
- area: 'topArea',
- type: 'Widget',
- name: 'logo',
- content: YourFantaticLogo,
- contentProps: {
- logo:
- 'https://img.alicdn.com/tfs/TB1_SocGkT2gK0jSZFkXXcIQFXa-66-66.png',
- href: '/',
- },
- props: {
- align: 'left',
- width: 100,
- },
-});
-
-init(document.getElementById('lce'));
-```
-
-### 工程化配置：
-```json
-{
- "externals": {
- "@alilc/lowcode-engine": "var window.AliLowCodeEngine",
- "@alilc/lowcode-engine-ext": "var window.AliLowCodeEngineExt"
- }
-}
-```
-
-### cdn 可选方式：
-#### 方式 1（推荐）：alifd cdn
-```html
-https://alifd.alicdn.com/npm/@alilc/lowcode-engine@1.0.0/dist/js/engine-core.js
-
-https://alifd.alicdn.com/npm/@alilc/lowcode-react-simulator-renderer@1.0.0/dist/js/react-simulator-renderer.js
-```
-
-#### 方式 2：unpkg
-```html
-https://unpkg.com/@alilc/lowcode-engine@1.0.0/dist/js/engine-core.js
-
-https://unpkg.com/@alilc/lowcode-react-simulator-renderer@1.0.0/dist/js/react-simulator-renderer.js
-```
-
-#### 方式 3：jsdelivr
-```html
-https://cdn.jsdelivr.net/npm/@alilc/lowcode-engine@1.0.0/dist/js/engine-core.js
-
-https://cdn.jsdelivr.net/npm/@alilc/lowcode-react-simulator-renderer@1.0.0/dist/js/react-simulator-renderer.js
-```
-
-#### 方式 4：使用自有 cdn
-将源码中 packages/engine/dist 和 packages/(react|rax)-simulator-renderer/dist 下的文件传至你的 cdn 提供商

-## 💻 本地调试
-
-```bash
-$ git clone git@github.com:alibaba/lowcode-engine.git
-$ cd lowcode-engine
-$ npm install
-$ npm run setup
-$ npm start
-```
-
-> 📢 npm 访问速度较慢，阿里员工可以使用 tnpm，其他同学建议使用 cnpm 或者指定镜像 registry。
->
-> 📢 node 版本限定在 14
->
-> 📢 windows 环境必须使用 [WSL](https://docs.microsoft.com/zh-cn/windows/wsl/install)，其他终端不保证能正常运行
-
-lowcode-engine 启动后，提供了几个 umd 文件，可以结合 [lowcode-demo](https://github.com/alibaba/lowcode-demo) 项目做调试，文件代理规则参考[这里](https://www.yuque.com/lce/doc/glz0fx)。

-## ✨ Features
-
-- 🌈 An extension-oriented kernel engine extracted from an enterprise-level low-code platform, pursuing the design concept of the smallest kernel and the strongest ecology
-- 📦 Out-of-the-box high-quality ecological elements, including material systems, setters, plugins, etc.
-- ⚙️ A complete tool chain, supporting the full-link R&D cycle of ecological elements such as material systems, setters, and plug-ins
-- 🔌 Powerful expansion capability, has supported nearly 100 various vertical low-code platforms
-- 🛡 Developed with TypeScript, providing complete type definition files
-
-## 🎯 Compatible Environments
-
-- Modern browsers (Chrome >= 80, Edge >= 80, last 2 safari versions, last 2 firefox versions)
-
-## 📚 Engine Protocol
-
-The engine fully implements the "Alibaba Mid-Backend Front-End Basic Construction Protocol Specification" and "Alibaba Mid-Backend Front-End Material Protocol Specification". The protocol stack is a key part of whether materials in the low-code field can be circulated.
-
-
-
-## 🌰 Usage example
-
-```bash
-npm install @alilc/lowcode-engine --save-dev
-```
-
-> **TIPS: Only cdn import is supported, npm package is used to provide code hinting capabilities such as typings**
-
-```ts
-import { init, skeleton } from '@alilc/lowcode-engine';
-
-skeleton.add({
- area: 'topArea',
- type: 'Widget',
- name: 'logo',
- content: YourFantaticLogo,
- contentProps: {
- logo:
- 'https://img.alicdn.com/tfs/TB1_SocGkT2gK0jSZFkXXcIQFXa-66-66.png',
- href: '/',
- },
- props: {
- align: 'left',
- width: 100,
- },
-});
-
-init(document.getElementById('lce'));
-```
-
-### Engineering configuration:
-```json
-{
- "externals": {
- "@alilc/lowcode-engine": "var window.AliLowCodeEngine",
- "@alilc/lowcode-engine-ext": "var window.AliLowCodeEngineExt"
- }
-}
-```
-
-### cdn optional method:
-#### Method 1: alifd cdn

-## 💻 Local debugging
-
-```bash
-$ git clone git@github.com: alibaba/lowcode-engine.git
-$ cd lowcode-engine
-$ npm install
-$ npm run setup
-$ npm start
-```
-
-> 📢 npm access speed is slow, Alibaba employees can use tnpm, other students recommend using cnpm or specifying a mirror registry.
->
-> 📢 node version limited to 14
->
-> 📢 Windows environment must use [WSL](https://docs.microsoft.com/zh-cn/windows/wsl/install), other terminals are not guaranteed to work normally
-
-After lowcode-engine is started, several umd files are provided, which can be debugged in combination with the [lowcode-demo](https://github.com/alibaba/lowcode-demo) project. Refer to the file proxy rules [here](https:/ /www.yuque.com/lce/doc/glz0fx).

+## 📚 Engine Protocol
+
+The engine fully implements the "Alibaba Mid-Backend Front-End Basic Construction Protocol Specification" and "Alibaba Mid-Backend Front-End Material Protocol Specification". The protocol stack is a key part of whether materials in the low-code field can be circulated.
+
+
+
+## 🌰 Usage example
+
+```bash
+npm install @alilc/lowcode-engine --save-dev
+```
+
+> **TIPS: Only cdn import is supported, npm package is used to provide code hinting capabilities such as typings**
+
+```ts
+import { init, skeleton } from '@alilc/lowcode-engine';
+
+skeleton.add({
+ area: 'topArea',
+ type: 'Widget',
+ name: 'logo',
+ content: YourFantaticLogo,
+ contentProps: {
+ logo:
+ 'https://img.alicdn.com/tfs/TB1_SocGkT2gK0jSZFkXXcIQFXa-66-66.png',
+ href: '/',
+ },
+ props: {
+ align: 'left',
+ width: 100,
+ },
+});
+
+init(document.getElementById('lce'));
+```
+
+### Engineering configuration:
+```json
+{
+ "externals": {
+ "@alilc/lowcode-engine": "var window.AliLowCodeEngine",
+ "@alilc/lowcode-engine-ext": "var window.AliLowCodeEngineExt"
+ }
+}
+```
+
+### cdn optional method:
+#### Method 1: alifd cdn
+```html
+https://alifd.alicdn.com/npm/@alilc/lowcode-engine@1.0.0/dist/js/engine-core.js
+
+https://alifd.alicdn.com/npm/@alilc/lowcode-react-simulator-renderer@1.0.0/dist/js/react-simulator-renderer.js
+```
+
+#### Method 2: unpkg
+```html
+https://unpkg.com/@alilc/lowcode-engine@1.0.0/dist/js/engine-core.js
+
+https://unpkg.com/@alilc/lowcode-react-simulator-renderer@1.0.0/dist/js/react-simulator-renderer.js
+```
+
+#### Method 3: jsdelivr
+```html
+https://cdn.jsdelivr.net/npm/@alilc/lowcode-engine@1.0.0/dist/js/engine-core.js
+
+https://cdn.jsdelivr.net/npm/@alilc/lowcode-react-simulator-renderer@1.0.0/dist/js/react-simulator-renderer.js
+```
+
+#### Method 4: Use your own cdn
+Pass the files under packages/engine/dist and packages/(react|rax)-simulator-renderer/dist in the source code to your cdn provider

+## 💻 Local debugging
+
+```bash
+$ git clone git@github.com: alibaba/lowcode-engine.git
+$ cd lowcode-engine
+$ npm install
+$ npm run setup
+$ npm start
+```
+
+> 📢 npm access speed is slow, Alibaba employees can use tnpm, other students recommend using cnpm or specifying a mirror registry.
+>
+> 📢 node version limited to 14
+>
+> 📢 Windows environment must use [WSL](https://docs.microsoft.com/zh-cn/windows/wsl/install), other terminals are not guaranteed to work normally
+
+After lowcode-engine is started, several umd files are provided, which can be debugged in combination with the [lowcode-demo](https://github.com/alibaba/lowcode-demo) project. Refer to the file proxy rules [here](https:/ /www.yuque.com/lce/doc/glz0fx).
