如何在 Webpack 中将 @material-ui/core 指定为外部？
How does one specify @material-ui/core as an external in Webpack?
我将 React 组件发布为独立的 npmjs 包。我的 React 组件依赖 @material-ui/core 作为依赖项。我可以在我的 Webpack 配置文件中将 react 和 react-router-dom 包指定为外部包，但似乎 @material-ui/core 仍然捆绑到我的最终产品中而不是外部包。
webpack.config.js:
externals: {
'@material-ui/core': {
amd: '@material-ui/core',
commonjs: '@material-ui/core',
commonjs2: '@material-ui/core'
},
'react': {
amd: 'react',
commonjs: 'react',
commonjs2: 'react',
root: 'React'
},
'react-router-dom': {
amd: 'react-router-dom',
commonjs: 'react-router-dom',
commonjs2: 'react-router-dom'
}
},
output: {
filename: 'index.js',
libraryTarget: 'umd',
path: path.resolve(__dirname, 'build'),
umdNamedDefine: true
},
resolve: {
alias: {
'@material-ui/core': path.resolve(__dirname, './node_modules/@material-ui/core'),
'react': path.resolve(__dirname, './node_modules/react'),
'react-router-dom': path.resolve(__dirname, './node_modules/react-router-dom')
}
}
最终的捆绑包有：
module.exports=t(require("react"),require("react-router-dom"));
但是没有有require("@material-ui/core")。相反，Material UI 包似乎包含在包本身中，使其变得不必要地大。

引用 @material-ui/core 作为正则表达式而不是字符串。 /^\@material\-ui\/core\/.*/ 以匹配所有以相关命名空间开头的导入。
对我有用的正则表达式：
externals: [ /^@material-ui\/(core|icons)[\/a-zA-Z]*/ ]
导入样式为：import { Card } from '@material-ui/core'，看别人的回答。
使用样式导入：import Card from '@material-ui/core/Card'，见下文：
externals: [
externalForMaterialUi
]
function externalForMaterialUi(context, request, callback) {
if (/@material-ui.+/.test(request)) {
const name = request.replace(/^.*[\\/]/, '')
return callback(null, 'root MaterialUI.' + name);
}
callback();
}
umd cdn。 webpack 4.41.2, @material-ui/core 4.7.2
我将 React 组件发布为独立的 npmjs 包。我的 React 组件依赖 @material-ui/core 作为依赖项。我可以在我的 Webpack 配置文件中将 react 和 react-router-dom 包指定为外部包，但似乎 @material-ui/core 仍然捆绑到我的最终产品中而不是外部包。
webpack.config.js:
externals: {
'@material-ui/core': {
amd: '@material-ui/core',
commonjs: '@material-ui/core',
commonjs2: '@material-ui/core'
},
'react': {
amd: 'react',
commonjs: 'react',
commonjs2: 'react',
root: 'React'
},
'react-router-dom': {
amd: 'react-router-dom',
commonjs: 'react-router-dom',
commonjs2: 'react-router-dom'
}
},
output: {
filename: 'index.js',
libraryTarget: 'umd',
path: path.resolve(__dirname, 'build'),
umdNamedDefine: true
},
resolve: {
alias: {
'@material-ui/core': path.resolve(__dirname, './node_modules/@material-ui/core'),
'react': path.resolve(__dirname, './node_modules/react'),
'react-router-dom': path.resolve(__dirname, './node_modules/react-router-dom')
}
}
最终的捆绑包有：
module.exports=t(require("react"),require("react-router-dom"));
但是没有有require("@material-ui/core")。相反，Material UI 包似乎包含在包本身中，使其变得不必要地大。

引用 @material-ui/core 作为正则表达式而不是字符串。 /^\@material\-ui\/core\/.*/ 以匹配所有以相关命名空间开头的导入。
对我有用的正则表达式：
externals: [ /^@material-ui\/(core|icons)[\/a-zA-Z]*/ ]
导入样式为：
import { Card } from '@material-ui/core'，看别人的回答。使用样式导入：
import Card from '@material-ui/core/Card'，见下文：
externals: [
externalForMaterialUi
]
function externalForMaterialUi(context, request, callback) {
if (/@material-ui.+/.test(request)) {
const name = request.replace(/^.*[\\/]/, '')
return callback(null, 'root MaterialUI.' + name);
}
callback();
}
umd cdn。 webpack 4.41.2, @material-ui/core 4.7.2
