javascript-dom-analysis

What problem does it solve?

This Skill helps you quickly determine which frontend frameworks and libraries power a website, reducing time spent on manual investigation and guesswork.

Core Features & Use Cases

• Detects frameworks via runtime signals: Identifies likely technologies by matching JavaScript global variables and framework-specific hooks in the browser context.
• Detects frameworks via DOM patterns: Finds framework-related DOM attributes and markers (including server-rendering and scoped-CSS conventions) to increase confidence.
• Fingerprints builds and meta-frameworks: Infers bundlers and platforms from common asset paths and filenames (e.g., Next.js/_next, Nuxt/_nuxt), and checks for exposed source maps to assess implementation details and security exposure.
• Use Case: You are auditing a competitor’s app and need to confirm whether it is using Next.js, Vue, or another stack, while also checking whether source maps are publicly accessible.

Quick Start

Use the javascript-dom-analysis skill to analyze a target website URL and return detected frameworks, bundle patterns, exposed source-map signals, and common analytics scripts.
