## ✨ 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
```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).
