jest-axe VS eslint-plugin-jsx-a11y

I usually use a combination of Storybook + Chromatic, Cypress, and Jest + Testing Library + jest-axe. Fairly standard, I think? (Aside from Chromatic, but that's mainly for convenience)

And finally, we can use a cool library called jest-axe. You can use it to assert that your component doesn’t have any accessibility violations:

Tests are another place where plugins can bring more accessibility insights. I've used two, depending on the test setup: jest-axe and cypress-axe. They both add axe-core, Deque's testing solution to the testing environment.

I try to focus on the issues rather than individuals, but the root of the problems in the listed eslint plugin libraries points to ljharb.

If you do some simple digging into these libraries, you will find that these types of commits are quite common within them.

He would rather see the download count of these polyfill libraries https://github.com/ljharb/ljharb#projects-i-maintain increase, compared to assessing the health of the JavaScript ecosystem.

jsx-a11y is all about ensuring your DOM elements are accessible. This plugin will prompt you to include the correct ARIA attributes such as labels and roles, in addition to things like alt text.

You can also add ESLint now (props to @femincan for the suggestion). It comes with recommended settings for these plugins: typescript, prettier, react, react-hooks, jsx-a11y.

WAI-ARIA is important if you are writing custom components and do not follow the general rules for HTML tags. For example, if you are using a `div` as a button, you would need to add tags for accessibility. Yes, there are some other instances, like adding alt text to images or adding a title to an iframe, but these can all be handled with warnings in the editor using the jsx-a11y eslint plugin. Some other nuance will be up to the developer to make sure they follow the proper accessibility structure, but most use cases are outlined in the Daisy UI tailwind examples, they do a great job of using HTML properly and give fully accessible examples for their components. Take a look at the accordion example, you can tab into the accordion and use the arrow keys to navigate.

jsx-a11 (ESLint plugin) checks a couple other things.

When using react, I've been using the recommended rules from eslint-plugin-jsx-a11y. Am I naive for relying a lot on that to get a11y right? Of course I try to write semantic html too and do research for each topic, but it's a bit overwhelming and I feel like the eslint rules help me a lot.

I found the documentation but no solution here: https://github.com/jsx-eslint/eslint-plugin-jsx-a11y/blob/main/docs/rules/label-has-associated-control.md

eslint-plugin-jsx-a11y: Checks for accessiblity issues.

For example, Deque's open-source Axe project can help identify issues such as common HTML semantic errors, contrast problems, and more. There are even libraries that help integrate Axe into your project's linters, such as one for React called eslint-plugin-jsx-a11y.
