electron-inspector

Debugger UI for the main Electron process

Overview

This package wraps node-inspector, which can be used to debug JavaScript code running in the main Electron process. Getting node-inspector running can require somewhere between a little and a lot of effort depending on the Electron version you wish to debug. The goal of electron-inspector is to get node-inspector running with minimum effort on your part.

Prerequisites

• NPM v3
• NodeJS v4.5 (or later)
• electron, or electron-prebuilt, or electron-prebuilt-compile
• electron-rebuild (optional)

Quick Start

electron-inspector should be installed as a local dev dependency of your Electron app:

npm install electron-inspector --save-dev

The easiest way to run the inspector in a cross-platform manner is to add an NPM script to your package.json, for example:

"scripts": {
  "inspect-main": "electron-inspector"
}

Then run the inspect-main script on the command line with:

npm run inspect-main

Alternatively, if you don't want to mess with your package.json you can directly execute electron-inspector (macOS / Linux), or .\\node_modules\\.bin\\electron-inspector (Windows).

On startup electron-inspector will check for compatibility of the native modules in node-inspector with the Electron version you wish to debug, if the compatibility check fails and electron-rebuild is installed then the native modules will be automatically rebuilt. You can disable auto-rebuild using the --no-auto-rebuild command line option.

When electron-inspector finally gets node-inspector running you will see a URL printed to the console window. For example:

Visit http://127.0.0.1:8080/?port=5858 to start debugging.

You can then start Electron in debug mode and open the given URL in your browser.

Configuration

node-inspector can be configured in multiple ways, electron-inspector will pass through most of the supported command line options.

Command Line Options

electron-inspector accepts most of the commandline options node-inspector does:
