我正在用React和TypeScript用Babel 7创建一个模块化组件库。
我希望我的库的用户使用类似如下的语法导入组件:
import SomeComponent from "my-awesome-lib/SomeComponent"SomeComponent是我的-awesome lib包中的一个TSX模块:
import * as React from "react";
export default function () {
return <h1>SomeComponent</h1>
}my- And component的package.json文件的main字段为:
"main": "src/index.ts"我不想发布我的组件库的编译版本,因为我在我的组件中导入了CSS和其他资产,我希望我的包的所有用户都使用带有一些特定配置的Webpack。
现在我的问题是,从“my -awesome/ SomeComponent”导入SomeComponent失败,并出现解析错误:
ERROR in ../node_modules/wtf/index.tsx 4:9
Module parse failed: Unexpected token (4:9)
You may need an appropriate loader to handle this file type.
|
| export default function () {
> return <h1>WTF</h1>
| }看来,在node_modules中,Webpack并没有加载或转换TSX文件。
我在我的用户应用程序的根目录下使用了这个tsconifg.json (它导入了my - at lib):
{
"compilerOptions": {
"outDir": "./dist",
"module": "commonjs",
"target": "es5",
"jsx": "react",
"allowSyntheticDefaultImports": true,
"moduleResolution": "node",
"resolveJsonModule": true,
"esModuleInterop": true,
"downlevelIteration": true,
"lib": ["es5", "es2015", "dom", "scripthost"],
"typeRoots": ["node_modules/@types", "src/@types"],
},
"include": ["src/**/*", "node_modules/**/*"],
"exclude": []
}而Webpack的相关配置如下:
const tsModules = {
test: /\.(js|jsx|ts|tsx)$/,
include: [path.resolve('src')],
exclude: /node_modules/,
loader: 'babel-loader'
}
const resolve = {
alias: {
},
modules: [
'node_modules'
],
extensions: ['.tsx', '.ts', '.js']
}
module.exports = {
...
context: resolve('src'),
resolve: resolve,
module: {
rules: [
tsModules,
...
]
}
}如何让Webpack从node_modules加载和转换我的-awesome lib的TSX模块?

此设置假设您正在使用样式组件,并且没有css/scss。
这里重要的是在你的tsconfig中有"module":commonJS,在你的webpack配置中有libraryTarget:"commonJS“。External告诉webpack不要将你的库与React、React-DOM或styled-components捆绑在一起,而是在你要导入到的项目中寻找那些包。
您还需要将React、react-dom和styled components从package.json依赖项中取出,并将这些包放入您的对等依赖项中
const path = require("path");
const fs = require("fs");
const TerserPlugin = require('terser-webpack-plugin');
const appIndex = path.join(__dirname, "../src/main.tsx");
const appBuild = path.join(__dirname, "../storybook-static");
const { TsConfigPathsPlugin } = require('awesome-typescript-loader');
module.exports = {
context: fs.realpathSync(process.cwd()),
mode: "production",
bail: true,
devtool: false,
entry: appIndex,
output: {
path: appBuild,
filename: "dist/Components.bundle.js",
publicPath: "/",
libraryTarget: "commonjs"
},
externals: {
react: {
root: 'React',
commonjs2: 'react',
commonjs: 'react',
amd: 'react'
},
'react-dom': {
root: 'ReactDOM',
commonjs2: 'react-dom',
commonjs: 'react-dom',
amd: 'react-dom'
},
"styled-components": {
root: "styled-components",
commonjs2: "styled-components",
commonjs: "styled-components",
amd: "styled-components"
}
},
optimization: {
minimizer: [
new TerserPlugin({
terserOptions: {
parse: {
ecma: 8,
},
compress: {
ecma: 5,
warnings: false,
comparisons: false,
inline: 2,
},
mangle: {
safari10: true,
},
output: {
ecma: 5,
comments: false,
ascii_only: true,
},
},
parallel: true,
cache: true,
sourceMap: false,
})
],
},
resolve: {
extensions: [".web.js", ".mjs", ".js", ".json", ".web.jsx", ".jsx", ".ts", ".tsx"],
alias: {
"react-native": "react-native-web",
},
},
module: {
strictExportPresence: true,
rules: [
{ parser: { requireEnsure: false } },
{
test: /\.(ts|tsx)$/,
loader: require.resolve("tslint-loader"),
enforce: "pre",
},
{
oneOf: [
{
test: /\.(tsx?)$/,
loader: require.resolve('awesome-typescript-loader'),
options: {
configFileName: 'tsconfig.prod.json'
}
},
],
},
],
},
plugins: [
new TsConfigPathsPlugin()
],
node: {
dgram: "empty",
fs: "empty",
net: "empty",
tls: "empty",
child_process: "empty",
},
performance: false,
};注意:将应用程序中的一个点作为只包含您想要导出的组件的条目,这一点很重要。
也就是说,对于我来说,它是Main.tsx,在Main.tsx内部,它看起来是这样的。
export { Checkbox } from "./components/Checkbox/Checkbox";
export { ColorUtils } from "./utils/color/color";
export { DataTable } from "./components/DataTable/DataTable";
export { DatePicker } from "./components/DateTimePicker/DatePicker/DatePicker";
export { DateTimePicker } from "./components/DateTimePicker/DateTimePicker/DateTimePicker";
export { Disclosure } from "./components/Disclosure/Disclosure";这意味着webpack不会捆绑你不打算出口的东西。要测试您的捆绑包works,请尝试从捆绑包中导入一些带有require语法的内容,以绕过typescript类型,并在tsconfig中将allowJS设置为true。
类似const Button =require(“../path/to/js/console.log”).Button console.log(按钮);

我发现create-react-library非常有用

您正在排除node_modules目录(这通常是件好事):
const tsModules = {
test: /\.(js|jsx|ts|tsx)$/,
include: [path.resolve('src')],
exclude: /node_modules/,
loader: 'babel-loader'
}除了明确排除node_modules文件夹之外,由于src中的include属性,您还只允许babel-loader处理tsModules文件夹的内容。所以这个错误:
../node_modules/wtf/index.tsx 4:9模块解析失败:意外标记(4:9)中的
错误
合乎道理。
如果删除node_modules属性并在tsModules.exclude中更改正则表达式,则仍可以排除tsModules.include,但单个文件夹除外
const tsModules = {
// ...
exclude: /node_modules\/(?!my-awesome-lib)\/*/
// ...
}也可以,但是我还没有测试它,将my-awesome-lib目录添加到include数组中:
const tsModules = {
// ...
include: [
path.resolve(__dirname, './src'),
path.resolve(__dirname, './node-modules/my-awesome-lib')
]
// ...
}然后,您的node_modules/my-awesome-lib目录中的文件将传递babel-loader,它将转换typescript代码。
编辑:我想你的混淆来自于你的tsconfig.json文件和"include": ["src/**/*", "node_modules/**/*"],。巴别塔是在转译你的代码,而不是打字。因此,在根目录中放置一个tsconfig.json文件可能会对您的集成开发环境有所帮助(特别是如果您使用的是微软的VScode),但不会影响babel和@babel/preset-typescript如何转换您的代码。
