Inertia handles CORS (Cross-Origin Resource Sharing) issues by leveraging the server-side framework's built-in support for CORS. Since Inertia uses the same domain for both the server-side and client-side, CORS is not a significant concern. Here are the key points:
1. Server-Side Framework Support:
- Inertia uses the same server-side framework as the client-side, which means that the server-side framework handles CORS for Inertia. For example, Laravel provides built-in support for CORS, making it easy to configure CORS for Inertia applications[1][3][5].
2. No Separate CORS Configuration:
- Unlike traditional APIs, Inertia does not require a separate CORS configuration. This simplifies the process and reduces the complexity of managing CORS[3][5].
3. Built-in Authentication:
- Inertia uses the server-side framework's built-in authentication system, which eliminates the need for a special authentication system like OAuth. This also means that CORS is not a concern for authentication, as the authentication system is handled on the server-side[5].
4. Simplified Development:
- Inertia's approach to CORS simplifies the development process by eliminating the need for additional CORS configuration and handling. This allows developers to focus on building their application without worrying about CORS issues[3][5].
Overall, Inertia's use of the same domain for both the server-side and client-side, combined with the server-side framework's built-in support for CORS, makes it easy to handle CORS issues without additional configuration.
