使用Firebase远程配置而不是.env文件

// 示例代码：读取Firebase远程配置
import firebase from 'firebase/app';
import 'firebase/remote-config';

if (!firebase.apps.length) {
  firebase.initializeApp({
    apiKey: "YOUR_API_KEY",
    projectId: "YOUR_PROJECT_ID",
    appId: "YOUR_APP_ID",
    measurementId: "YOUR_MEASUREMENT_ID"
  });
}

const remoteConfig = firebase.remoteConfig();
remoteConfig.settings = {
  minimumFetchIntervalMillis: 3600000, // 设置默认的刷新间隔为1小时
};

remoteConfig.defaultConfig = ({
  'welcome_message': 'Welcome to our app!',
});

remoteConfig.fetchAndActivate()
  .then(() => {
    console.log('Remote config activated');
    const welcomeMessage = remoteConfig.getValue('welcome_message').asString();
    console.log(welcomeMessage);
  })
  .catch((err) => {
    console.error('Failed to fetch remote config', err);
  });
