Description
This plugin provides Accessibility (a11y) rules for React applications, enforcing WCAG standards.
Philosophy
Interlace fosters strength through integration. Instead of stacking isolated rules, we interlace security directly into your workflow to create a resilient fabric of code. We believe tools should guide rather than gatekeep, providing educational feedback that strengthens the developer with every interaction.
