从渲染器到主的电子调用

Question

正如How to call a function/module in Electron from my webpage? 中的回答，我试过了，但代码需要电子。

const { remote } = require('electron');
const mainProcess = remote.require('./main.js');

mainProcess.test();

我将渲染器作为单独的存储库并在构建时出错：

为了更好地回答这个问题，发布您的 package.json 并确保电子在您的依赖项中会有所帮助。如果不是，请 npm install electron，如果是，请尝试以下操作：

要让 ipcRenderer 和 ipcMain 工作，您需要 2 个东西

在您的主应用程序/main.js 中，您需要需要 ipcMain

const {app, BrowserWindow, ipcMain} = require('electron');

在您的渲染器进程中，您应该像这样要求它：

const { ipcRenderer } = require('electron');
