crossOrigin

Core Idea

Use crossOrigin to add a crossOrigin attribute to every <script> tag Next.js generates for next/script, controlling how cross-origin requests for those scripts are handled.

Key Concepts

• crossOrigin: string config option in next.config.js, applied to all next/script-generated <script> tags.
• 'anonymous': adds crossOrigin="anonymous".
• 'use-credentials': adds crossOrigin="use-credentials".

Code Examples

module.exports = {
  crossOrigin: 'anonymous',
}

• O que demonstra: aplicar crossOrigin="anonymous" a todas as tags <script> geradas por next/script.

Key Takeaways

1. Afeta somente scripts gerados via o componente next/script.
2. Só dois valores válidos: 'anonymous' ou 'use-credentials'.
