将自定义组件库中的 React 组件导入 HTML
Importing React component from custom component library into HTML
我创建了一个测试反应组件库(React、Typescript),并尝试使用 Rollup 将其打包到 UMD 中,以便我可以将组件导入到 HTML 页面中。
我创建的示例组件只采用 label
道具并将其着色为橙色。一些超级简单如此复杂的逻辑将被排除在等式之外。
用于呈现上述文本的 React 代码:
import * as React from 'react';
import * as Test from 'react-webpack-demo';
function App() {
return (
<div>
<h1>
{
React.createElement(Test.Brand, { label: 'Brand Label Text'})
}
</h1>
</div>
);
}
export default App;
以上组件通过Rollup打包成CJS格式导入。我还尝试将相同的内容打包到 UMD 中,以便可以将其导入 HTML。完整的 rollup.config.js
文件如下:
import resolve from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';
import typescript from '@rollup/plugin-typescript';
import external from 'rollup-plugin-peer-deps-external';
import packageJson from './package.json';
export default [
{
input: 'src/index.ts',
output: [
{
file: packageJson.main,
format: 'cjs',
sourcemap: true
},
{
file: packageJson.module,
format: 'umd',
name: 'Test',
sourcemap: true
}
],
plugins: [
resolve(),
babel({
exclude: 'node_modules/**',
presets: [
'@babel/preset-react',
'@babel/preset-typescript'
]
}),
external(),
commonjs(),
typescript({ tsconfig: './tsconfig.json' })
],
external: [
...Object.keys(packageJson.dependencies || {}),
...Object.keys(packageJson.peerDependencies || {})
]
}
]
然后我尝试将新打包的 UMD 文件导入我的 HTML 页面并将其渲染到 DOM 元素中:
<html lang="en-US">
<head>
<title>Test</title>
<meta charset="utf-8" />
<script src="./react-webpack-demo/dist/umd/index.js" crossorigin></script>
<script src="https://unpkg.com/react@17/umd/react.development.js" crossorigin></script>
<script src="https://unpkg.com/react-dom@17/umd/react-dom.development.js" crossorigin></script>
</head>
<body>
<h1>Testing rollup in plain HTML</h1>
<hr />
<div id='brand-test'></div>
<script>
const el = React.createElement;
const domContainer = document.getElementById('brand-test');
ReactDOM.render(el(
Test.Brand,
{
label: 'Demo works!'
}
), domContainer);
</script>
</body>
</html>
但是我得到以下错误:
The above error occurred in the component:
Brand@file:///Users/jacorbello/repos/temp/react-webpack-demo/dist/umd/index.js:33:1
Uncaught TypeError: React__namespace.createElement is not a function
Brand Brand.tsx:8
React 17
test.html:20 Brand.tsx:8:11
如有任何帮助,我们将不胜感激。
提前感谢您的宝贵时间!
脚本标签的顺序似乎不正确。您的库需要先导入 React,然后才能执行脚本。
只需修复订单即可正常运行
