electron-spawn is a tool that allows you to run JavaScript code inside a headless Electron (Chromium) window from the command line, making it easy to execute scripts with access to Electron's APIs. It's designed for developers who need to run Node.js-like scripts but with the ability to leverage Electron's features, such as handling images or other browser-based tasks, in a headless environment. The tool is particularly useful for testing or automating tasks that require Electron's capabilities without the need for a visible window.
