如何在React中渲染Firestore数据？

npm install firebase

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

const firebaseConfig = {
  // Firebase配置信息
};

firebase.initializeApp(firebaseConfig);

const db = firebase.firestore();

import React, { Component } from 'react';

class MyComponent extends Component {
  state = {
    data: []
  };

  componentDidMount() {
    const { db } = this.props;
    db.collection('myCollection').get()
      .then(querySnapshot => {
        const data = querySnapshot.docs.map(doc => doc.data());
        this.setState({ data });
      })
      .catch(error => {
        console.log('Error getting documents: ', error);
      });
  }

  render() {
    const { data } = this.state;

    return (
      <div>
        {data.map(item => (
          <div key={item.id}>{item.name}</div>
        ))}
      </div>
    );
  }
}

export default MyComponent;
