At Netlify, the core frontend team emphasizes making their interface accessible for all users, with every developer responsible for implementing and testing accessibility in their features. They use a standard PR template to guide reviewers through the process, including test plans and standard checks such as testing feature flag states, cross-browser compatibility, responsiveness, and ensuring changes are accessible. The team uses various tools like Storybook-addon-a11y, netlify-plugin-a11y, and @axe-core/react to catch accessibility issues early, with a focus on prioritizing bugs labeled as "bugs" to ensure timely fixes. By incorporating accessibility into their development workflow, Netlify aims to build an increasingly inclusive and accessible product for all users.
