axe DevTools Linter allows you to check your code for accessibility issues (similarly to how a code linter checks for coding issues). axe DevTools Linter is easy to configure and use, and it can check React (.js, .jsx, and .tsx), Vue (.vue), Angular (.component.html), HTML (.html and .htm), and Markdown (.md and .markdown) files so you can avoid common accessibility defects.


Checking inline Angular templates is not currently supported.
