React

React is a JavaScript library for building user interfaces, created by Meta. It lets you build web apps from reusable pieces called components. For vibe coders, React is the most popular UI framework that AI coding tools generate code for — making it the default choice for building web apps with AI.

Example

You tell Cursor to 'build a dashboard with a sidebar, header, and a grid of stat cards.' It generates React components for each piece — Sidebar, Header, StatCard — that snap together like building blocks into a complete interface.

React dominates vibe coding because AI models have been trained on massive amounts of React code. When you prompt an AI to build a web interface, it almost always reaches for React first.

Why React Dominates Vibe Coding

  1. AI knows it deeply — More React training data exists than any other UI framework
  2. Component-based — Breaks UIs into small, reusable pieces that AI generates well
  3. Massive ecosystem — Libraries for everything (routing, forms, animations, data fetching)
  4. Next.js integration — The most popular React framework for full-stack apps

Core Concepts (Simplified)

ConceptWhat It Means
ComponentA reusable piece of UI (button, card, page)
PropsData you pass into a component
StateData that can change and trigger re-renders
JSXHTML-like syntax you write inside JavaScript
HookSpecial functions for managing state and effects

React in the Vibe Coding Stack

Most vibe coding tools default to a React-based stack:

  • V0 — Generates React + Tailwind components from prompts
  • Bolt / Lovable — Scaffold full React apps from descriptions
  • Cursor / Windsurf — AI pair-programming in React projects
  • Next.js — The go-to React framework for production apps

Do You Need to Learn React?

Not deeply — but understanding the basics helps:

  • Read component structure — Know what a component returns
  • Understand props — How data flows between components
  • Recognize hooksuseState, useEffect show up everywhere
  • Trust AI for the rest — Let it handle the complex patterns
