Javascript 如何使用webpack 5只编译一个typescript文件,而排除所有其他文件?
我有一个Node.js运行时,为react应用程序提供服务 ,以下是文件夹结构: 我在react应用程序中运行Javascript 如何使用webpack 5只编译一个typescript文件,而排除所有其他文件?,javascript,node.js,reactjs,typescript,webpack,Javascript,Node.js,Reactjs,Typescript,Webpack,我有一个Node.js运行时,为react应用程序提供服务 ,以下是文件夹结构: 我在react应用程序中运行npm运行build,以编译react应用程序本身 然后我想从项目的根运行npm run build,只将index.ts文件编译到/dist/index.js,并忽略react app文件夹中的内容 这是我的webpack.config.ts: const webpack = require("webpack"); const path2 = require(&q

,以编译react应用程序本身
然后我想从项目的根运行npm run build
,只将index.ts文件编译到/dist/index.js,并忽略react app文件夹中的内容
这是我的webpack.config.ts:
const webpack = require("webpack");
const path2 = require("path");
const nodeExternals = require("webpack-node-externals");
const copyFiles = require('copy-webpack-plugin');
module.exports = {
entry: './index.ts',
target: "node",
mode: "production",
externals: [nodeExternals()],
resolve: {
extensions: ['.ts']
},
module: {
rules: [
// all files with a `.ts` extension will be handled by `ts-loader`
{ test: /index.ts$/, loader: 'ts-loader', exclude: [ path2.resolve(__dirname, 'react-app')]}
]
},
plugins: [new webpack.HotModuleReplacementPlugin(), new copyFiles({ patterns: [{ from: 'react-app/build', to: 'build'}]})],
output: {
path: path2.resolve(__dirname, 'dist'),
filename: 'index.js'
},
};
我尝试过只包含index.ts文件,并以百万种方式排除react应用程序文件夹,但webpack一直在尝试编译react应用程序文件夹中的ts文件。
这是我的package.json:
{
"name": "frontend-service",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "node dist/index.js",
"build": "webpack",
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"express": "^4.17.1"
},
"devDependencies": {
"@types/express": "^4.17.11",
"@types/node": "^14.14.31",
"copy-webpack-plugin": "^7.0.0",
"ts-loader": "^8.0.17",
"ts-node": "^9.1.1",
"typescript": "^4.2.2",
"webpack": "^5.24.2",
"webpack-cli": "^4.5.0",
"webpack-node-externals": "^2.5.2"
}
}
请帮助。我最初认为评论是错误的,因为我在我的tsconfig的“compileOptions”中添加了“include”:[“index.ts”]并得到:
error TS5023: Unknown compiler option 'include'.
但显然我不得不把它放在编译之外,比如:
{
"compilerOptions": {
// Your options.....
},
"include": ["./index.ts"]
}
这就行了
但是,react项目将不再生成,因为它发现:
a different version of webpack-dev-server was detected higher up in the tree
我建议不要将react typescript项目放在节点typescript项目中。最好创建一个根文件夹,并将react项目放在节点项目旁边的文件夹中。在tsconfig.json
