javascript - 如何不依赖 React/Webpack 3 应用程序中的相对路径

Question

我正试图摆脱这个:

从'../../services/somewhere'导入{something};

而是使用:

从'services/somewhere'导入{something}；

我找到这篇文章，但它只有 1.x 和 2.x 的示例 https://moduscreate.com/blog/es6-es2015-import-no-relative-path-webpack/

我项目的主文件夹名为 app。

我已经在我的 webpack.config.babel.js 中尝试了这两种方法，但到目前为止还没有成功。

3.x style: https://webpack.js.org/configuration/resolve/#resolve-modules

resolve: {
  modules: [path.resolve(__dirname, 'app'), 'node_modules', path.resolve('node_modules')]
}

---

2.x style: https://moduscreate.com/blog/es6-es2015-import-no-relative-path-webpack/

resolve: {
  modules: [
    path.resolve('./app'),
    path.resolve('./node_modules')
  ]
}

有什么想法吗？

Webpack 配置

可能是你的 eslint 配置有问题？例如，在您的 .eslintrc 中，尝试将 app 添加到您的解析器设置中:

{
  "...": {},
  "settings": {
    "import/resolver": {
      "node": {
        "moduleDirectory": [
          "app",
          "node_modules"
        ]
      }
    }
  },
}
