如何将类属性插件添加到Webpack [英] How to add the class properties plugin to webpack

问题描述

我正在尝试获取 @babel/plugin-proposal-class-properties 与webpack一起使用.

I'm trying to get the @babel/plugin-proposal-class-properties to work with webpack.

我已使用节点软件包管理器(npm)安装了插件.

I have installed the plugin with node package manager (npm).

我没有.babelrc，所以我假设此插件应该放入webpack.config.js.

I don't have a .babelrc, so I'm assuming that this plugin is supposed to go into webpack.config.js.

我找到了此页面，这使我相信以下内容是不错的设置将插件包含在webpack.config.js文件中的方法:

I found this page which led me to believe that the following was a good setup for including the plugin in the webpack.config.js file:

const webpack = require('webpack');
const ClassPropertiesPlugin = require("@babel/plugin-proposal-class-properties"); //installed via npm
const config = {
    entry:  __dirname + '/js/index.jsx',
    output: {
        path: __dirname + '/dist',
        filename: 'bundle.js',
    },
    resolve: {
        extensions: ['.js', '.jsx', '.css']
    },
    module: {
        rules: [
            {
                test: /\.jsx?/,
                exclude: /node_modules/,
                use: 'babel-loader'
            },
            {
                test: /\.(jpe?g|png|gif|svg)$/i,
                loader: "file-loader?name=/public/[name].[ext]",
            },
            {
                test: /\.css$/,
                use: ['css-loader'],
            },
        ]
    },
    plugins: [ClassPropertiesPlugin]
};


module.exports = config;

但是，这导致了错误

<personal info>\static\node_modules\webpack\bin\webpack.js:348
                        throw err;
                        ^

    at bootstrapNodeJSCore (internal/bootstrap/node.js:743:3)

当我看着它时，这似乎意味着我包括了插件错误，但我不确定如何.我还尝试了以下完全相同的错误:

When I looked into it, it seemed that this meant I was including the plugin incorrectly, but I'm not sure how. I've also tried the following with the exact same error:

const webpack = require('webpack');
const config = {
    entry:  __dirname + '/js/index.jsx',
    output: {
        path: __dirname + '/dist',
        filename: 'bundle.js',
    },
    resolve: {
        extensions: ['.js', '.jsx', '.css']
    },
    module: {
        rules: [
            {
                test: /\.jsx?/,
                exclude: /node_modules/,
                use: 'babel-loader'
            },
            {
                test: /\.(jpe?g|png|gif|svg)$/i,
                loader: "file-loader?name=/public/[name].[ext]",
            },
            {
                test: /\.css$/,
                use: ['css-loader'],
            },
        ]
    },
    plugins: ["@babel/plugin-proposal-class-properties"]
};


module.exports = config;

我也不能做new ClassPropertiesPlugin()，因为它说它不是构造函数.

I also can't do new ClassPropertiesPlugin() because it says it's not a constructor.

没有此插件，我的webpack(无法构建特定的.jsx文件 这就是为什么我需要这个插件的原因，否则可以正常使用)

Without this plugin, my webpack (which fails to build a particular .jsx file which is why I need this plugin, but otherwise works fine) looks like

const webpack = require('webpack');
const config = {
    entry:  __dirname + '/js/index.jsx',
    output: {
        path: __dirname + '/dist',
        filename: 'bundle.js',
    },
    resolve: {
        extensions: ['.js', '.jsx', '.css']
    },
    module: {
        rules: [
            {
                test: /\.jsx?/,
                exclude: /node_modules/,
                use: 'babel-loader'
            },
            {
                test: /\.(jpe?g|png|gif|svg)$/i,
                loader: "file-loader?name=/public/[name].[ext]",
            },
            {
                test: /\.css$/,
                use: ['css-loader'],
            },
        ]
    },
};


module.exports = config;

我希望npm run build能够正常工作而不会引发错误，并让插件正确地编译javascript.正确地说，我的意思是编译器不会针对特定错误抛出此错误我正在使用的文件.

I would like the npm run build to work without throwing an error, and have the plugin compile the javascript correctly. By correctly, I mean that the compiler does not throw this error on a particular file I'm using.

推荐答案

理想情况下，您将拥有下，否则，您可以在其中包含babel配置您的package.json(不推荐)或您的Webpack配置的babel-loader 选项.

Ideally, you would have a .babelrc file at the root of your project (just create one if it doesn’t exist) and include it under "plugins", otherwise you can include a babel config in your package.json (not recommended) or in your webpack config’s babel-loader options.
