CSP Origin Restrictions Between Live Reload and Production Bundles

Content Security Policy and Origin Shifts
Capacitor applications often utilize a development configuration with a local IP address to enable live reload. In this state, the web view operates under a network-based origin, which typically allows for flexible network request patterns during the development cycle.
When transitioning to a production build, the web assets are bundled locally. This changes the application origin to capacitor://localhost on iOS and http://localhost on Android. This shift in origin can trigger Content Security Policy (CSP) violations that were not present during local testing.
The challenge lies in defining a CSP that maintains strict security while permitting necessary native plugin communication and external API calls across both development and production schemes.
- How should the CSP be structured to support both the live reload IP and the production local schemes?
- What is the recommended approach for dynamically adjusting the CSP based on the build target?
