no-electron-experimental-features

Disallow enabling Electron webPreferences.experimentalFeatures.

Targeted pattern scope

This rule targets Electron BrowserWindow and BrowserView constructor options that set webPreferences.experimentalFeatures to true.

What this rule reports

This rule reports webPreferences.experimentalFeatures: true in Electron renderer configuration objects.

Why this rule exists

Electron recommends disabling experimental platform features in production renderers because they expand the runtime surface area and can bypass hardening assumptions.

❌ Incorrect

new BrowserWindow({
 webPreferences: {
  experimentalFeatures: true,
 },
});

✅ Correct

new BrowserWindow({
 webPreferences: {
  experimentalFeatures: false,
 },
});

Behavior and migration notes

This rule includes an autofix for literal boolean values.

experimentalFeatures: true is rewritten to experimentalFeatures: false.

ESLint flat config example

import sdl from "eslint-plugin-sdl-2";

export default [
 {
  plugins: { sdl },

  rules: {
   "sdl/no-electron-experimental-features": "error",
  },
 },
];

When not to use it

Disable only for short-lived experiments that explicitly require Electron experimental features and are isolated behind documented review gates.
