jsx-a11y and Component-Level Guardrails

Catch issues with lint rules in your codebase.

Catch Bugs Before They Ship

Many accessibility mistakes are easy to spot in code. A linter can flag them as you type, long before a real user ever hits the barrier. 🛡️

Meet jsx-a11y

The eslint-plugin-jsx-a11y package adds accessibility rules to ESLint for JSX. It checks your components for common, well-known a11y errors.

npm install eslint-plugin-jsx-a11y --save-dev
