Application Router Setup

Set up the SAP Application Router (approuter) as the single entry-point for your Cloud Foundry application.

Purpose

The SAP Application Router is a key infrastructure component for web-facing applications running in Cloud Foundry on SAP BTP. It is used to:

• Serve static content: Deliver HTML, CSS, and JavaScript files directly to the client.
• Authenticate users: Trigger authentication processes via XSUAA to ensure secure access.
• Rewrite URLs: Modify URLs of requests to match routing rules.
• Forward or proxy requests: Redirect client requests to the appropriate backend services.
• Propagate user information: Include user data (user ID, roles) when forwarding requests to backend services.

In the Neo environment, the platform handled routing and authentication implicitly. In Cloud Foundry, you must explicitly set up the approuter as a separate Node.js module.
