electron+vue+ts窗口间通信

---

    "@types/node": "^20.3.1","@vitejs/plugin-vue": "^4.1.0","@vueuse/electron": "^10.2.1","electron": "^25.2.0","electron-packager": "^17.1.1","typescript": "^5.0.2","vite": "^4.3.9","vue-tsc": "^1.4.2"

一. 目的

现有场景: 用户点击图,在新窗口展示实时数据

---

二.逻辑分析

vue作为纯渲染线程不具备操作本地数据以及窗口间通讯的功能,必须由经electron主进程解决.
因此官方为我们提供了IpcRederer向主进程发送消息的能力. 以及IpcMain主进程监听处理消息的能力.

由于ts和electron上下文隔离策略限制不允许直接使用request读取IpcRederer对象. 我们可以借助 usevue vue的第三方集成api综合库.读取ipcRederer

因此请注意
在vue渲染线程中 我们要参考的是usevue的官方文档 —> usevue
在electron主进程参考 —> electron

1. 用户点击图谱
2. A窗口向主进程发送打开B窗口请求
3. 主进程收到A窗口消息, 创建B窗口.返回响应
4. A窗口接收响应, 向生产者信道发送数据
5. 主进程监听生产者信道接收数据,主进程将监听消息发送给消费者信道
6. B窗口读取消费者信道数据

三. 代码示例

A.vue

import {useIpcRenderer} from "@vueuse/electron";
const ipcRenderer = useIpcRenderer();async function openTextBox() {await res.open()console.log(res.data.value)// 向发送数据resp.value = ipcRenderer.invoke('product-msg', res.data.value)if(resp.value){// 创建新窗口ipcRenderer.send('textBox', '/browse')resp.value=false}
}
