About React
React is the most widely-used JavaScript library for building user interfaces, developed and maintained by Meta. It introduced a component-based architecture and a virtual DOM for efficient updates. React powers millions of websites and applications, often paired with frameworks like Next.js, Remix, or Gatsby.
- Declarative, component-based UI architecture
- Virtual DOM for efficient diffing and DOM updates
- Unidirectional data flow with state and props
- Massive ecosystem of hooks, libraries, and tools
- JSX syntax combining JavaScript and HTML-like markup
- Used both as a single-page app library and with SSR frameworks
How We Detect React
Our scanner identifies React usage through the following signals:
- react.development.js or react.production.min.js in page scripts
- __REACT_FIBER_TRACING__ or __reactFiber attributes in DOM
- React DevTools hook detection in window object
- Technology stack entry listing React as the framework
- JSX-compiled output patterns in page JavaScript bundles
