关于node.js：在将google-cloud与webpack集成时遇到问题


Getting an issue while integrating google-cloud with webpack

我正在将google-cloud npm软件包与我的react应用程序集成在一起，并且我正在使用Firebase。

我遇到的错误-

WARNING in ./~/google-cloud/~/hash-stream-validation/index.js Module

有人可以帮我解决这个问题吗？

我看到您正在使用webpack，并且我假设您正在后端使用google-cloud库。

尝试将其放入您的webpack配置中：

1
2
3
4
5
6
7
config = {
    // ...
    externals: {
        '@google-cloud/storage': 'commonjs @google-cloud/storage'
    },
    // ...
}

解释

用于后端的模块并不是真正为了捆绑在一起而设计的(请参阅：带有Webpack的后端应用程序)。因此，我们使用webpack的externals配置来排除不能很好地解决捆绑问题的库。当应用程序运行时，它们只是从node_modules目录中进行require()修改。

如果您不想一一指定问题模块，请尝试使用webpack-node-externals自动排除所有模块。
