Electron 中的错误消息和控制台日志?

在开发过程中如何在 Electron 中查看错误消息和控制台日志?另外，是否可以将日志直接写入文件?

How do you view error messages and console logs in Electron during development? Also, is it possible for the logs to be written directly into a file?

有点像 Chrome 的开发工具显示的错误和控制台日志:除了在 Electron 而不是 Chrome 中.

Kind of like the errors and console logs displayed by Chrome's dev tools: Except in Electron rather than Chrome.

推荐答案

在您的 BrowserWindow 上调用函数 openDevTools() 这将打开您在 Chrome 中找到的相同开发工具.我在我的博客 http://www.mylifeforthecode.com/debugging-renderer-process-in-electron/.

On your BrowserWindow call the function openDevTools() this will open the same dev tools you find in Chrome. I wrote about this on my blog at http://www.mylifeforthecode.com/debugging-renderer-process-in-electron/.

这是一个包含 openDevTools 的简单 main.js 文件:

Here is a simple main.js file that includes openDevTools:

var app = require('app');
var BrowserWindow = require('browser-window');

var mainWindow = null;

app.on('window-all-closed', function() {
  if (process.platform != 'darwin')  
    app.quit();
});

app.on('ready', function() {    
  mainWindow = new BrowserWindow({width: 800, height: 600});  
  mainWindow.loadUrl('file://' + __dirname + '/index.html');
  mainWindow.openDevTools();
  mainWindow.on('closed', function() {
    mainWindow = null;
  });  
});

您也可以使用远程模块通过渲染器进程访问它.对于我一直在修补的应用程序，我将函数 toggleDevTools 绑定到 F12.像这样的:

You can also access this via a renderer process using the remote module. For the apps I have been tinkering with I bind the function toggleDevTools to F12. Something like this: 

  var remote = require('remote');           
  document.addEventListener("keydown", function (e) {  
    if (e.keyCode === 123) { // F12
      var window = remote.getCurrentWindow();
      window.toggleDevTools();         
    }
  });

请注意，我只在 Windows 中使用 Electron 测试了上述内容.我假设 Linux 和 Mac 版本的工作方式相同.如果您运行的是 Mac 或 Linux，请告诉我是否没有.

Note that I have only tested the above with Electron in Windows. I am assuming the Linux and Mac versions work the same. If you are running Mac or Linux please let me know if they do not.
