javascript - Electron ipcRenderer 与 ipcMain 同步

Question

我的问题是当我从渲染器进程调用 ipcMain 操作时渲染器线程被卡住，直到 ipcMain 操作完成(同步而不是异步)

代码示例:

渲染器.js

export const startCopy = data => {

  // Copy files tree to the drive
  ipcRenderer.send('copy-files', data);

  return new Promise((resolve, reject) => {

    ipcRenderer.on('copy-files-finished', (event, error) => {

      resolve(error);
    });
  });

}

Main.js

ipcMain.on('copy-files', (event, data) => {

  const error = copyFiles();

  console.log(error);

  event.sender.send('copy-files-finished', error);
});

先谢谢了。

是的，我在解决 Electron 问题时遇到了同样的问题，所以我想向您推荐一个我认为据我所知最好的选择

Do time consuming task or system related task in separate window which is independent from Main window(Render process) It will never affect your Main window(Render process).

之后发送消息到主窗口(渲染过程)以通知和更新 UI。
