【SpreadJS v15.2 新特性介绍】框架版本支持：React 18 & Angular 14
SpreadJS V15.2中对React 与 Angular 框架进行了增强，支持了React 18 与 Angular 14React 18
React18有一个新的ReactDOM Render API。升级React 18时，需要导入“ReactDOM/client”并使用新的 ReactDOM API，否则控制台将报告警告。
安装React 18
npm install react react-dom
//or if you are using yarn
yarn add react react-dom
更新Client Rendering APIs
首次安装React 18时，会将在控制台中看到如下警告：
ReactDOM.render is no longer supported in React 18. Use createRoot instead. Until you switch to the new API, your app will behave as if it’s running React 17. Learn more: https://reactjs.org/link/switch-to-createroot
要消除此警告，需要使用新的renderAPI，以下是新版本与旧版本的对比：
旧版本：
import { render } from 'react-dom';
const container = document.getElementById('app');
render(<App tab="home" />, container);新版本：
import { createRoot } from 'react-dom/client';
const container = document.getElementById('app');
const root = createRoot(container);
root.render(<App />);其余使用方式与之前相同。
Angular 14
无论是SpreadJS还是在线表格编辑器均可以在Angular 14上正确运行。
升级Angular 14
在终端中输入“ng update”并执行，然后ng将检查要更新的包。
> ng update
We analyzed your package.json, there are some packages to update:
Name Version Command to update
--------------------------------------------------------------------------------
@angular/cli 13.3.8 -> 14.0.3 ng update @angular/cli
@angular/core 13.3.11 -> 14.0.3 ng update @angular/core
There might be additional packages which don't provide 'ng update' capabilities that are outdated.
You can update the additional packages by running the update command of your package manager. 然后运行“ng update@angular/cli”将angular更新为v14。
PS：如果提示升级不成功，请将 node 版本升级到14.15.0或更高版本。
