带有Firebase的GatsbyJS-WebpackError:ReferenceError:IDBIndex未定义

问题描述

我在 gatsby开发上收到错误消息.与此非常相似: https://github.com/firebase/firebase-js-sdk/issues/2222 ，但是我收到的 gatsby开发而不是gatsby构建错误.我做了很多研究，但是找不到有效的解决方案.最初，我在 gatsby构建时遇到了问题，例如这篇文章: https://github.com/firebase/firebase-js-sdk/issues/2222 ，但我使用自定义onCreateWebpackConfig进行了解析(您可以在下面找到它).

I'm received error with gatsby develop. It's very similar to this one: https://github.com/firebase/firebase-js-sdk/issues/2222, but I'm received error with gatsby develop, not with gatsby build. I did a lot of research but I can't find working solution.At first I had a problem with gatsby build, like in this post: https://github.com/firebase/firebase-js-sdk/issues/2222, but I resolved it with custom onCreateWebpackConfig(you can find it below).

堆栈:-盖茨比- Firebase(可能与此有关的错误)-Redux

Stack:- Gatsby- Firebase(error probably with that)- Redux

我还要删除.cache和node_modules并重新安装所有内容，但这没有用.

I'm also delete .cache and node_modules and install everything again, but it didn't work.

错误:

There was an error compiling the html.js component for the development server.

          return callback(null, `umd ${request}`);
        }
        callback();

    });
  }

推荐答案

以下代码段由于您的情况而仅在 build 环境下有效( stage ==='build-html'):

The following snippet will only work on build environment because of your condition (stage === 'build-html'):

   exports.onCreateWebpackConfig = ({ stage, actions, getConfig }) => {
      if (stage === 'build-html') {
        actions.setWebpackConfig({
          externals: getConfig().externals.concat(function(context, request, callback) {
            const regex = /^@?firebase(\/(.+))?/;
            if (regex.test(request)) {
              return callback(null, `umd ${request}`);
            }
            callback();
          }),
        });
      }
    };

删除它并像这样使用它:

Remove it and use it like this:

   exports.onCreateWebpackConfig = ({ stage, actions, getConfig }) => {
        actions.setWebpackConfig({
          externals: getConfig().externals.concat(function(context, request, callback) {
            const regex = /^@?firebase(\/(.+))?/;
            if (regex.test(request)) {
              return callback(null, `umd ${request}`);
            }
            callback();
          }),
        });
    };

关于新问题，您可以按照此主题中的解决方法进行操作.，这是Gatsby中第三方模块尝试访问构建应用时尚未定义的DOM元素(通常是 window )的常见错误.因此，您需要等待直到定义了 window .您可以通过两种方式实现这一目标:

Regarding the new issue, you can follow a workaround in this topic, This is a common error in third-party modules in Gatsby when they try to reach a DOM element (usually window) that is not already defined when the app builds. So, you need to wait until window is defined. You can achieve this in two ways:

1)使用以下条件增强您的Firebase:

1) Instancing your firebase with a condition like this:

import firebase from '@firebase/app';
import '@firebase/auth';
import '@firebase/firestore';
import '@firebase/functions';

const config = {
   ... firebase config here
};

let instance;

export default function getFirebase() {
  if (typeof window !== 'undefined') {
    if (instance) return instance;
    instance = firebase.initializeApp(config);
    return instance;
  }

  return null;
}

注意 if(typeof window！=='undefined')语句

2)通过忽略Webpack配置中的firebase模块，例如显示其文档.在您的 gatsby-node.js 中:

2) By ignoring firebase module in you webpack configuration like shows their docs. In your gatsby-node.js:

exports.onCreateWebpackConfig = ({ stage, loaders, actions }) => {
  if (stage === "build-html") {
    actions.setWebpackConfig({
      module: {
        rules: [
          {
            test: /bad-module/,
            use: loaders.null(),
          },
        ],
      },
    })
  }
}

替换Firebase(或程序包名称)的错误模块"

此代码段替换了您先前的似乎在 concat()函数中引发错误的代码段.

This snippet replaces your previous one that seems to throw an error in concat() function.
