This package provides a process manager UI for Electron applications.

It opens a window displaying a table of every processes run by the Electron application with information (type, URL for webContents, memory..).

⚠️ For @electron>=3.0.0, <7.x, use version 0.7.1 of this package. For versions >=7.x, use latest.

It can be useful to debug performance of an app with several webview.

It's inspired from Chrome's task manager.

Features

• Memory reporting
• Link memory data to web-contents (for electron >=1.7.1)
• Kill a process from the UI

⚠️ Unfortunately, memory info are no longer available in Electron>=4 (see electron/electron#16179)
