Process Manager UI for Electron Apps

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..).

:warning: 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)
• [x] Kill a process from the UI
• [x] Open developer tools for a given process
• [x] CPU metrics
• [x] Sort by columns

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