JSX Code Formatting Best Practices
Writing clean, readable, and well-formatted JSX code improves maintainability, collaboration, and reduces bugs in React projects.
1. Consistent Indentation
Maintain uniform indentation for readability:
- Use 2 spaces per indentation level consistently.
- Avoid mixing tabs and spaces.
- Indent nested JSX elements and expressions properly.
2. Limit Line Length
Keep lines short for better readability:
- Recommended: 80–120 characters per line.
- Break long JSX expressions into multiple lines.
- Helps readability across editors and devices.
3. Logical Spacing
Use blank lines to separate components and logical blocks:
- Separate nested components and sections with empty lines.
- Add space around curly braces and operators.
- Improves scanning of complex JSX structures.
4. Meaningful Names
Choose descriptive and consistent names for components and variables:
- Components: use PascalCase like
UserProfile. - Props & Variables: use camelCase like
userCount. - Functions: descriptive verbs like
handleClick().
5. Follow Community Conventions
Adhere to established React and JSX style guides:
- Use Airbnb or Standard React style guides.
- Lint JSX code with ESLint and Prettier.
- Keep consistent formatting across your React projects.
Before Formatting
const App = () => { return <div><h1>Hello</h1><p>Welcome</p></div>; }After Formatting
const App = () => {
return (
<div>
<h1>Hello</h1>
<p>Welcome</p>
</div>
);
}Why JSX Formatting Matters
Proper JSX formatting ensures your React code is readable, maintainable, and less error-prone. Clean JSX improves collaboration and works seamlessly with automated tools like ESLint and Prettier.
- Readable JSX is easier to debug and maintain.
- Reduces bugs caused by misreading nested JSX blocks.
- Supports automated linting and formatting tools.
- Encourages professional and consistent coding habits in React projects.
