[Bug] npm run lint crashes during typescript-eslint rule initialization

[VickyKumarOfficial]

Problem statement

The root lint command crashes while ESLint is loading @typescript-eslint/no-unused-expressions. It never reaches normal lint diagnostics, so contributors and CI cannot use lint as a quality gate.

Environment observed

• Branch: main
• Node.js: 22.17.1
• ESLint: 9.33.0
• typescript-eslint: 8.11.0
• @typescript-eslint/eslint-plugin: 8.11.0

Steps to reproduce

1. Install dependencies from the committed npm lockfile.
2. From the repository root, run:

npm run lint

3. The same failure can be isolated to tracked application paths with:

npx eslint src backend

Actual behavior

ESLint exits with code 1 before linting the codebase:

TypeError: Error while loading rule '@typescript-eslint/no-unused-expressions':
Cannot read properties of undefined (reading 'allowShortCircuit')
Occurred while linting src/App.tsx

Expected behavior

The lint command should inspect the configured source files, report actionable violations, and return a stable exit code without crashing inside a rule implementation.

Root-cause evidence

This dependency combination matches the upstream typescript-eslint extension-rule compatibility defect fixed in version 8.15.0:

typescript-eslint/typescript-eslint#10338

The current package range/lock state can resolve an affected 8.11.0 plugin alongside ESLint 9.x.

Proposed resolution

1. Upgrade typescript-eslint and all direct @typescript-eslint/* packages together to a compatible release (8.15.0 or newer).
2. Refresh and commit package-lock.json using the project's supported Node/npm version.
3. Confirm there are no stale, mixed versions with npm ls typescript-eslint @typescript-eslint/eslint-plugin @typescript-eslint/parser @typescript-eslint/utils eslint.
4. Keep the rule enabled; do not mask the crash by disabling @typescript-eslint/no-unused-expressions.
5. Pin or document the supported Node version if the dependency set requires it.

Acceptance criteria

• npm ci completes from a clean checkout.
• npm run lint completes without a rule-loader exception.
• The lint command checks the intended tracked frontend/backend source paths.
• npm run build still succeeds.
• Updated dependency and lockfile versions are committed consistently.
• Supported Node/npm versions are documented or pinned.

Verification checklist

npm ci
npm ls typescript-eslint @typescript-eslint/eslint-plugin @typescript-eslint/parser @typescript-eslint/utils eslint
npm run lint
npm run build
