PersistentUrlInterceptor class

An interceptor that dynamically modifies the base URL for HTTP requests.

This interceptor allows the application to use a persistent base URL stored in local storage, enabling dynamic switching between different API environments (e.g., development, staging, production) without requiring app rebuilds.

How it works:

  1. Retrieves the stored base API URL from persistent storage
  2. Replaces the host of the original request URL with the stored host
  3. Preserves the original path and other URL components

Use Cases:

  • Switching between development and production APIs
  • Supporting multiple tenants with different API endpoints
  • Testing against different server environments

Example:

// Original request: https://api.example.com/v1/users
// Stored base URL: https://staging.example.com
// Final request: https://staging.example.com/v1/users
