As with all framework, React comes with its personal set of greatest practices and optimum patterns. Let’s discover some ideas for writing sturdy React code:
Modular Elements
Break elements into reusable, composable items:
// Dangerous
perform App() {
return (
<header>
<nav>
<brand>
<hyperlinks>
</nav>
<h1>Welcome!</h1>
<footer>
<copyright>
</footer>
</header>
);
}
// Good
perform Nav() {
return (
<nav>
<Brand />
<Hyperlinks />
</nav>
);
}
perform Header() {
return (
<header>
<Nav />
<h1>Welcome!</h1>
<Footer />
</header>
);
}
This encourages reusability.
Unidirectional Information Move
Comply with the one-way knowledge circulate paradigm:
- State is handed down as props
- Occasions bubble as much as set off state modifications
This prevents cascading updates throughout elements.
Strict Mode
Allow Strict Mode throughout growth to catch widespread points:
// index.js
ReactDOM.render(
<React.StrictMode>
<App />
</React.StrictMode>,
doc.getElementById('root')
);
Strict mode checks for deprecated lifecycles, unsafe practices, and extra.
ESLint & Prettier
Use ESLint and Prettier to implement constant code model. Frequent plugins embody:
eslint-plugin-react
eslint-plugin-jsx-a11y
(accessibility checks)eslint-plugin-react-hooks
Abstract
- Modular elements for reusability
- Unidirectional knowledge circulate
- Strict Mode for catching points
- ESLint & Prettier for constant model
Following React greatest practices results in apps which are scalable, sturdy and maintainable.
