HOC vs Render Props vs Custom Hooks

Compare the three code-sharing strategies on readability, testing, and composition.

HOC vs Render Props vs Custom Hooks is a free React Academy lesson on CoddyKit — lesson 3 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the React Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.

Welcome

In this lesson you will compare HOCs, render props, and custom hooks on readability, testability, composability, and when each one is the right tool.

The Problem All Three Solve

All three patterns exist to share stateful logic or behaviour across multiple components — without copy-pasting code.

HOC: Pros

HOCs work with class components (before hooks), integrate seamlessly with libraries that do not support hooks, and can be applied transparently without changing the wrapped component's source code.

HOC: Cons

HOCs create wrapper hell in DevTools, can cause prop collisions if two HOCs inject the same prop name, and are harder to type correctly in TypeScript. Refs must be forwarded explicitly.

Render Props: Pros

Render props make data flow explicit — you can see exactly what values the behaviour provider exposes. They work in both class and function components and are great for headless component APIs.

Render Props: Cons

Nested render-prop callbacks create 'callback hell'. Inline render prop functions break memoization. They add visual noise compared to a simple hook call.

Custom Hooks: Pros

Custom hooks are the most composable: call multiple hooks, combine them, and the component's JSX remains clean. They are easy to test in isolation. TypeScript types are straightforward.
const { on, toggle } = useToggle();
const { x, y } = useMouse();
// No wrapper components, no callback nesting

Custom Hooks: Cons

Custom hooks only work in function components (not class components). They cannot inject JSX — they return data/functions only. Some use cases (like auth guards that redirect) need HOCs or wrapper components.

Decision Guide

Need to redirect/guard a route? Use a HOC or wrapper component. Building a headless UI library? Render props or hooks. Sharing stateful logic in function components? Custom hook. Wrapping a class component or third-party? HOC.

Modern Default: Hooks First

In a modern React codebase (all function components), custom hooks are the default choice. Only reach for HOCs or render props when hooks cannot solve the problem.

Quick Check

Which code-sharing pattern is the recommended default for extracting stateful logic in modern React function components?

Recap

HOCs, render props, and custom hooks all share logic. Hooks are the modern default: clean, composable, testable. HOCs are for class components and route guards. Render props for headless UI. Choose based on context.
