NodeJS Webpack 5别名解析通配符

我想知道在Webpack 5中设置别名时是否可以使用某种通配符。
我当前的别名如下所示:

// ...
resolve: {
  alias: {
    'scope:a$': path.resolve(__dirname, 'node_modules/@scope/package/a'),
    'scope:b$': path.resolve(__dirname, 'node_modules/@scope/package/b'),
    'scope:c$': path.resolve(__dirname, 'node_modules/@scope/package/c'),
  },
},
// ...

字符串
这个很好用。它目前正在阻止我的项目中的相对路径地狱。我可以汇入:

@use 'scope:a' as a;


而不是:

@use '../../../../../a' as a;


但我很想用一个化名来解决这个问题。大概是这样的:

// ...
resolve: {
  alias: {
    'scope:': path.resolve(__dirname, 'node_modules/@scope/package/*'),
  },
},
// ...


此范例实作会掷回错误:
错误在...
模块生成失败...
...
Webpack的文档似乎没有提到resolve.alias的任何可能的通配符。有人知道在Webpack 5别名中是否可以使用通配符吗?
先谢了。

正如@KarloSpacapan提到的,我们可以指定resolve.alias的目录路径
例如:
项目结构:

$ tree -L 2 -I node_modules
.
├── dist
│   ├── bundle.js
│   └── main.css
├── package-lock.json
├── package.json
├── src
│   ├── index.js
│   └── style.scss
└── webpack.config.js

2 directories, 7 files

字符串
让我们创建一个名为@scope/package的假包,其中包含node_modules中的a.scssb.scssc.scss文件。
node_modules/@scope/package/a.scss

.a {
    color: red;
}


node_modules/@scope/package/b.scss

.b {
    color: aqua;
}


node_modules/@scope/package/c.scss

.c {
    color: beige;
}


src/style.scss

// @use 'scope:a' as a;
// @use 'scope:b' as b;
// @use 'scope:c' as c;

@use 'scope/a' as a;
@use 'scope/b' as b;
@use 'scope/c' as c;


src/index.js

import './style.scss';


webpack.config.js

const path = require('path');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');

module.exports = {
    mode: 'production',
    entry: './src/index.js',
    output: {
        filename: 'bundle.js',
        clean: true,
    },
    module: {
        rules: [
            {
                test: /\.s[ac]ss$/i,
                use: [MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader'],
            },
        ],
    },
    resolve: {
        // alias: {
        //  'scope:a$': path.resolve(__dirname, 'node_modules@scope/package/a'),
        //  'scope:b$': path.resolve(__dirname, 'node_modules@scope/package/b'),
        //  'scope:c$': path.resolve(__dirname, 'node_modules@scope/package/c'),
        // },

        alias: {
            scope: path.resolve(__dirname, 'node_modules/@scope/package'),
        },
    },
    plugins: [new MiniCssExtractPlugin()],
};
