如何避免加载用于Web构建的Expo通知捆绑包? [英] How to avoid loading Expo notifications bundle for web build?

问题描述

我正在使用expo并响应本机网络.我已经将FCM集成到Web通知中，但是expo还加载了我不想要的通知包.

I am using expo and react native web. I have integrated FCM for notifications for web but expo also loads a notifications bundle which I do not want.

问题是当在浏览器中收到通知并单击消息时，应用程序获得了焦点，但崩溃并显示"TypeError:_emitter undefined".这是src/Notifications/Notifications.ts:40

The issue is when the notification is received in the browser and message is clicked, the app gets the focus but crashes saying "TypeError: _emitter is undefined". This is on this line in src/Notifications/Notifications.ts:40

_emitter.emit('notification', notification);

因此，似乎expo尝试使用其Notifications模块.我可以将其删除以进行网络构建吗?

So, it seems expo tries to use its Notifications module. Can I remove that for web build?

推荐答案

解决方案1-升级到expo@39.0.4:

npm install expo@39.0.4

解决方案2-初始化_emitter属性

1. 安装以下软件包:

npm install --save fbemitter

1. 在App.js/tsx文件中添加一个侦听器

    import * as Notifications from 'expo/build/Notifications/Notifications'
    
    // By calling "Notifications.default.addListener()" function,
    // the _emitter variable will be initialized correctly
    Notifications.default.addListener(event => {
      console.log('message data', event.data)
    })
