What tools can you use to check accessibility issues in an Angular app?

Beginner

Answer

The Angular ESLint plugin can catch some accessibility mistakes right inside your code editor while you type. The axe DevTools browser extension and Lighthouse in Chrome scan a running page and list real accessibility problems along with clear suggestions on how to fix each one.
// Running Lighthouse from the command line
npx lighthouse http://localhost:4200 --view

// Reports accessibility issues like missing labels, low contrast text, and more
