我的目标是使用webpack为ES6中的反应组件库创建一个模块。
我正在使用:
我需要将react
和react-dom
指定为peerDependencies,以便开发人员不会下载它。
这是我package.json
的相关部分:
"peerDependencies": {
"react": "15.4.1"
},
"dependencies": {
"chalk": "1.1.3",
"compression": "1.6.2",
"cross-env": "3.1.3",
"immutable": "3.8.1",
"invariant": "2.2.1",
"lodash": "4.16.4",
"minimist": "1.2.0",
"sanitize.css": "4.1.0",
"warning": "3.0.0",
"react-onclickoutside": "5.8.3",
"styled-components": "1.1.2",
"classnames": "2.2.5"
},
"devDependencies": {
"react": "15.4.1",
"react-dom": "15.4.1",
根据https://webpack.github.io/docs/configuration.html#externals和https://webpack.github.io/docs/library-and-externals.html,
我尝试过以下配置:
1
externals: {
react: {
root: 'React',
commonjs2: 'react',
commonjs: 'react',
amd: 'react'
},
'react-dom': {
root: 'ReactDOM',
commonjs2: 'react-dom',
commonjs: 'react-dom',
amd: 'react-dom'
}
},
2。 外部:{ 反应:'反应', 'react-dom':'react-dom', }
3
externals: {
react: 'React',
'react-dom' : 'ReactDOM',
}
4
externals: {
react: 'umd react',
'react-dom' : 'umd react-dom'
}
5
externals: {
// Use external version of React
"react": "React",
"react-dom": "ReactDOM"
},
我总是有这个错误:
Dynamic page loading failed Error: addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's `render` method, or you have multiple copies of React loaded (details: https://bf.me/react-refs-must-have-owner).(…)
所以我想知道,文档不是很清楚。
2017年12月,即2018年1月,我如何排除React
和ReactDOM
被捆绑?

这里是我的webpack配置,它只是基础,因为我正在处理一个较小的项目
const {resolve} = require('path');
module.exports = {
entry: './demo/react/main.jsx',
output: {
filename: 'bundle.js',
path: resolve(__dirname, 'demo/react/dist')
}
module: {
rules: [
{
test: /\.jsx?$/,
use: [
{
loader: 'babel-loader'
}
]
}
]
},
externals: {
// Use external version of React
'react': 'React',
'react-dom': 'ReactDOM'
}
};

在你试过的例子中没有看到这个。正如OP所提到的,以下JSON配置对它们不起作用。
从GitHub issue #1275开始,试试这个:
{
externals: {
// Use external version of React
"react": "React",
"react-dom": "ReactDOM"
}
}
如果这不起作用,请尝试阅读整个问题页面。有一些建议可能会最终为你效劳。

可以将一种方式放入单独的文件中,例如reactjs
通过
entry: {
app:'./src/app.jsx',
reactjs:[
'react','react-dom' ,
]
}
output: {
path : path.join(__dirname, 'public'),
filename : 'bundle.[name].js',
publicPath : '/public/'
},
plugins : [
new webpack.optimize.CommonsChunkPlugin({
name: 'reactjs',
})
]
现在webpack
将构建两个文件bundle.app.js
和bundle.reactjs.js
。
将它们包含在index.html
首先做出反应的应用中。
