Firebase/auth import source-map warnings

Question

我正在使用 firebase 库 v7.15.5 构建一个 React 应用程序，当我导入“firebase/auth”时，它工作正常但它在终端中向我发出警告：

这是我初始化 firebase 模块的文件代码：

import app from 'firebase/app';
import 'firebase/database';
import 'firebase/auth';

const config = {
  apiKey: process.env.API_KEY,
  authDomain: process.env.AUTH_DOMAIN,
  databaseURL: process.env.DB_URL,
  storageBucket: process.env.STORAGE_BUCKET,
};

app.initializeApp(config);

const database = app.database();
const auth = app.auth();

export { database, auth };

尝试删除node_modules并全部重新安装，但并没有解决问题。也许我应该以不同的方式导入它或配置 webpack 或 tsconfig？我不知道。

感谢您的帮助。

Answer 1

如果您绝对需要源映射（我不认为您真的需要，因为您的解决方案是禁用它们），您可以为 firebase（或只是 firebase/auth）添加一个exclude rule。示例（自行构建）：

{
    enforce: "pre",
    test: /\.js$/,
    loader: "source-map-loader",
    exclude: /node_modules\/@firebase/ //to exclude firebase from source-map
    exclude: /node_modules\/@firebase\/auth/ //to just exclude firebase auth from source-map
  },

注意： 只使用上面的排除规则之一

Answer 2

如果您不想再看到此警告，可能的解决方案是添加此修复程序编辑文件 node_modules/react-scripts/config/webpack.config.js，并将其粘贴到行 performance: false 之后，

    ignoreWarnings: [
      // Ignore warnings raised by source-map-loader.
      // some third party packages may ship miss-configured sourcemaps, that interrupts the build
      // See: https://github.com/facebook/create-react-app/discussions/11278#discussioncomment-1780169
      /**
       *
       * @param {import('webpack').WebpackError} warning
       * @returns {boolean}
       */
      function ignoreSourcemapsloaderWarnings(warning) {
        return (
          warning.module &&
          warning.module.resource.includes('node_modules') &&
          warning.details &&
          warning.details.includes('source-map-loader')
        );
      },
    ],

Answer 3

将 firebase 版本升级到 9 为我们修复了它。

注意，必须更新才能使用兼容包：

import firebase from 'firebase/compat/app';
import 'firebase/compat/auth';
import 'firebase/compat/firestore';

Answer 4

当我调查这些警告时，我注意到其中一些提到了 polyfill（虽然不是全部）。较旧的 webpack 版本默认包含 node.js 核心模块的 polyfill。从 webpack 5 开始，情况就不是这样了。这可能与这些警告有关。

参考：https://github.com/facebook/create-react-app/issues/11756

在我的例子中，使用 webpack 4 而不是 webpack 5 摆脱了警告并且没有破坏任何东西。这可能是一个解决方案，只要您的代码不需要网页 5+。

如果你想尝试这个解决方案，你需要：

1. 从 package.json 中删除以下依赖项： “反应脚本”：“5.0.0”， （你的版本可能更高）

2. 将以下依赖项添加到您的 package.json： “反应脚本”：“4.0.3”，

3. 删除您的 node_modules 文件夹

4. 运行 npm 安装

Answer 5

首先，去存储， https://console.firebase.google.com/project/

选择您的项目名称

然后去存储

然后

规则选项卡和更改允许读取、写入：如果为假；为真；如下所示。

rules_version = '2';
service firebase.storage {
    match /b/{bucket}/o {
        match /{allPaths=**} {
            allow read, write: if true;
    }
  }
}

Answer 6

通过从 webpack.config 中删除这些代码行来解决问题

{
    enforce: "pre",
    test: /\.js$/,
    loader: "source-map-loader"
  },
