In plain English

Eruda is a developer console for mobile browsers, written in JavaScript. Mobile browsers don't have built-in developer tools like desktop browsers do, which makes debugging web pages on a phone difficult. Eruda solves this by injecting a floating panel into any web page that provides console output, error logging, and other debugging tools directly on the device. To use it, you add a short script snippet to your web page either via npm or a CDN link like jsDelivr or cdnjs, then call eruda.init(). A small button appears on the page, and tapping it opens the developer panel. It can be used during development or to debug issues in production on mobile. The project also has a related remote debugging tool called chii and an Android app called eruda-android that loads pages with Eruda automatically.

Copy-paste prompts

Prompt 1

I'm debugging a web app on a phone and need to see console errors. Show me how to add Eruda via CDN and call eruda.init() in my HTML page.

Prompt 2

Help me add Eruda to my React app only in development mode so the debug panel appears on mobile but is stripped from production builds.

Prompt 3

My web page crashes silently on iOS. Show me how to use Eruda to capture the JavaScript error and see the full stack trace on the device.

Prompt 4

Using npm, help me install Eruda and conditionally load it only when a debug query parameter is present in the URL.
