NodeIntegration default false limits Node API usage in windows

Question

In NodeWebKit, the nodeIntegration flag is set to false by default for each window, preventing Node APIs from being accessed in the renderer process. This default behavior is intended to mitigate security risks, but it also imposes a limitation on developers who wish to use Node features without manually toggling the flag for every window.
The goal is to evaluate whether the default should remain false or shift to true to simplify development, while ensuring that any change can be safely rolled back if a schema alteration introduces unintended exposure of Node APIs.
Constraints include:

Security of the user environment.
Compatibility with existing applications that rely on nodeIntegration being disabled.
Ability to revert to a safe state after a schema change.

Unresolved questions:

Is there a documented roadmap for changing the default nodeIntegration value in future releases?
What are the specific security risks if nodeIntegration is enabled globally?
How can a rollback mechanism be implemented to safely revert the schema if the new default leads to vulnerabilities?

Answer
Keep the default nodeIntegration:false for each NW.js window; changing it globally to true is not recommended without explicit per‑window opt‑in.
Confirmed facts

The nodeIntegration flag defaults to false in every window, blocking direct Node.js API access from the renderer.
Setting it to true exposes the full Node.js API, allowing any injected script to perform file‑system, process, or environment operations, which can lead to remote code execution.
There is no published roadmap to change this default in future NW.js releases.
Reverting to the safe false state can be done by setting the flag back to false per window or recompiling the app with the flag explicitly disabled.

Steps to verify current behavior

Inspect the application manifest or package.json for the nodeIntegration key; if absent or false, the default is active.
Run a test script in the renderer that attempts require('fs'); an error indicates the flag is effectively disabled.
To test rollback, temporarily set nodeIntegration:true, confirm the API works, then revert the flag and re‑run the test to ensure the API is blocked again.

Missing diagnostic detail
Do you rely on any preload scripts that expose a limited Node API surface? If yes, keeping the default false preserves that isolation; if no, you may consider enabling the flag per‑window instead of globally.
