从node.js错误中获取Firestore文档

问题描述

代码：

(global as any).XMLHttpRequest = require("xhr2");

import firebase from "firebase/app";
import "firebase/firestore";

// All are fake values
const firebaseConfig = {
  apiKey: "dsfds",authDomain: "sdf.firebaseapp.com",databaseURL: "https://sdfs.firebaseio.com",projectId: "dssdf",storageBucket: "sdsdfsdf.appspot.com",messagingSenderId: "wearwefas",appId: "asdfgerhdfgdettgerg",measurementId: "sdfgsregserg",};

const app = firebase.initializeApp(firebaseConfig);
app
  .firestore()
  .doc("foo/bar")
  .get()
  .then((doc) => {
    console.log(doc.data());
  })
  .catch((e) => {
    throw e;
  });

Firebase SDK版本：7.19.1

该代码与esbuild捆绑在一起，后者与汇总相同。

在终端中运行时，它输出：

[2020-09-10T13:35:55.539Z]  @firebase/app:
      Warning: This is a browser-targeted Firebase bundle but it appears it is being
      run in a Node environment.  If running in a Node environment,make sure you
      are using the bundle specified by the "main" field in package.json.

      If you are using Webpack,you can specify "main" as the first item in
      "resolve.mainFields":
      https://webpack.js.org/configuration/resolve/#resolvemainfields

      If using Rollup,use the rollup-plugin-node-resolve plugin and specify "main"
      as the first item in "mainFields",e.g. ['main','module'].

我已连接到互联网，但表明我处于离线状态。我该如何解决？

解决方法

只要您使用--platform=node，这应该在esbuild版本0.7.0（刚刚发布）中起作用。
