React add document firestore

问题

以下是你提供的代码的翻译部分：

Hi I have a problem on code below I can't add a firestore collection to a db, when the setDoc line is executed it doesn't add the document to the collection, and the strange thing is that it doesn't print anything console, I'm using react, even though I use the add doc it does the same thing, the app is already connected to firebase because I logged in so the parameters are correct, what can it be?

**FirebaseFile.js**

import { initializeApp } from 'firebase/app';

这似乎是你合并了两个文件，但将其列为一个文件。如果这是一个文件，那么导入`db`两次将会有问题：

```javascript
import { initializeApp } from 'firebase/app';
import { getFirestore } from 'firebase/firestore';

var firebaseConfig = {
  ...
};

// 初始化 Firebase
var app = initializeApp(firebaseConfig);
export const db = getFirestore(app); &lt;-------- 使用这个。

import React, { useRef, useState } from 'react';
import { doc, setDoc, collection } from 'firebase/firestore';

import styled from 'styled-components';
import EmailEditor from '../../../src';
import sample from './sample.json';
import sample2 from './sample2.json';
import sample3 from './sample3.json';
import { db } from '../firebase'; &lt;----- 这是什么？

否则，如果你在本地遇到问题，请确保你启动了本地的`Firestore Emulator`，否则你可能会更新你的实时 Firestore 实例。

// 检测开发环境
connectFirestoreEmulator(db, '127.0.0.1', 6060);
英文:

It seems like you merged two files but you listed this as one file. If that's one file, then you are importing db twice which would be a problem:

import { initializeApp } from &#39;firebase/app&#39;;
import { getFirestore } from &#39;firebase/firestore&#39;;
var firebaseConfig = {
...
};
// Initialize Firebase
var app = initializeApp(firebaseConfig);
export const db = getFirestore(app); &lt;-------- Use this.
import React, { useRef, useState } from &#39;react&#39;;
import { doc, setDoc,collection } from &#39;firebase/firestore&#39;;
import styled from &#39;styled-components&#39;;
import EmailEditor from &#39;../../../src&#39;;
import sample from &#39;./sample.json&#39;;
import sample2 from &#39;./sample2.json&#39;;
import sample3 from &#39;./sample3.json&#39;;
import { db } from &#39;../firebase&#39;; &lt;----- What is this?

Otherwise, if you are having the problem locally, make sure you are starting your local Firestore Emulator or else you'll probably be updating your live Firestore instance.

// detect for development ENV
connectFirestoreEmulator(db, &#39;127.0.0.1&#39;, 6060);
