NW.js package.json nodejs integration and remote URL boundaries

Node.js Integration in Mixed Contexts
NW.js allows the execution of Node.js APIs directly within the DOM context by setting "nodejs": true in the package.json configuration. This integration enables seamless access to the filesystem and OS-level operations from the client-side JavaScript environment.
Security Boundary Constraints
A critical design concern arises when the application must load remote URLs while maintaining Node.js capabilities for local windows. While the mixed context provides high utility, enabling this integration for windows that navigate to external domains introduces significant security risks regarding Remote Code Execution (RCE).
There is uncertainty regarding the most effective way to isolate these environments without disabling Node.js globally for the entire application instance.
- How can the
package.jsonor window options be configured to restrict Node.js API access specifically for remote frames while preserving it for local entry points? - What is the recommended mechanism to enforce a permission boundary between the Chromium rendering engine and the Node.js instance when handling untrusted external content?
