# Application Debugging
|
|
|
|
Whenever your Electron application is not behaving the way you wanted it to,
|
|
an array of debugging tools might help you find coding errors, performance
|
|
bottlenecks, or optimization opportunities.
|
|
|
|
## Renderer Process
|
|
|
|
The most comprehensive tool to debug individual renderer processes is the
|
|
Chromium Developer Toolset. It is available for all renderer processes,
|
|
including instances of `BrowserWindow`, `BrowserView`, and `WebView`. You
|
|
can open them programmatically by calling the `openDevTools()` API on the
|
|
`webContents` of the instance:
|
|
|
|
```javascript
|
|
const { BrowserWindow } = require('electron')
|
|
|
|
let win = new BrowserWindow()
|
|
win.webContents.openDevTools()
|
|
```
|
|
|
|
Google offers [excellent documentation for their developer tools][devtools].
|
|
We recommend that you make yourself familiar with them - they are usually one
|
|
of the most powerful utilities in any Electron Developer's tool belt.
|
|
|
|
## Main Process
|
|
|
|
Debugging the main process is a bit trickier, since you cannot open
|
|
developer tools for them. The Chromium Developer Tools can [be used
|
|
to debug Electron's main process][node-inspect] thanks to a closer collaboration
|
|
between Google / Chrome and Node.js, but you might encounter oddities like
|
|
`require` not being present in the console.
|
|
|
|
