电子ipcRenderer与ipcMain同步

Question

My problem is when i call ipcMain operation from the renderer process the renderer thread is stuck untill the ipcMain operation is done(sync instead async)

Code example :

Renderer.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);
});

Thanks ahead.

Yes same problem I encountered when I was working on electron problem, So I would like to suggest you one options that I think It is best one from my knowledge

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).

after that send Message to Main window(Render process) in order to Notify and update UI.
