Bump typescript to 6.0.2, ts-jest to 29.4.9, eslint to 10.1.0, typescript-eslint to 8.58.0, and eslint-plugin-import-x to 4.16.2

[Copilot]

Modernizes the TypeScript toolchain across the repo. Key blocker: ts-jest <29.4.7 declared typescript: ">=4.3 <6" as a peer dep, making TypeScript 6.x incompatible — 29.4.7 extended that range to <7.

Changes

• typescript → 6.0.2 across all packages (tests/, scripts/, dashboard/, dashboard/api/)
• ts-jest → ^29.4.9 in tests/ (first version with TypeScript 6.x peer dep support)
• eslint → ^10.1.0 and @eslint/js → ^10.0.0 in tests/ (already at this level in scripts/)
• typescript-eslint → ^8.58.0 in tests/ and scripts/
• eslint-plugin-import replaced with eslint-plugin-import-x@^4.16.2 in tests/ — the v2.x line only declares eslint ≤9 peer dependency support; eslint-plugin-import-x is the maintained fork that supports eslint 8/9/10
• eslint-import-resolver-typescript@^4.4.4 added to tests/ for TypeScript module resolution with the new plugin
• engines field added to tests/package.json (^20.19.0 || ^22.13.0 || >=24) matching scripts/package.json, making the Node.js version requirement explicit for contributors and CI

TypeScript 6 compatibility fix

TypeScript 6 no longer auto-resolves @types/node for node: protocol imports — it now requires an explicit types declaration. Added to scripts/tsconfig.json:

"types": ["node"]

Without this, the compiler emits TS2591 on every node:* import and TS2503 on NodeJS.* namespace references.

ESLint config update

tests/eslint.config.mjs updated to import from eslint-plugin-import-x and use the import-x/ rule prefix. The no-unused-modules rule includes suppressMissingFileEnumeratorAPIWarning: true since ESLint 10 removed the FileEnumerator API that rule depends on.

Copilot bump the version of eslint-plugin-import to the one which works with @eslint/js: 10.0.0

Copilot bump the version of eslint-plugin-import to the one which works with @eslint/js: 10.0.0

Done in 435dcfc. eslint-plugin-import v2.x only supports eslint ≤9, so it's been replaced with eslint-plugin-import-x@^4.16.2 (a maintained fork that supports eslint 8/9/10) along with eslint-import-resolver-typescript@^4.4.4 for TypeScript resolution. The eslint config import and rule prefix were updated from import/ → import-x/.

Testing result that I ran from vscode copilot

Changes Tested:
TypeScript: 5.3.3 → 6.0.2
ESLint: 9.0.0 → 10.1.0
ts-jest: 29.1.2 → 29.4.9
typescript-eslint: 8.57.1 → 8.58.0
eslint-plugin-import replaced with eslint-plugin-import-x 4.16.2
Added tsconfig.json "types": ["node"] configuration
Test Results:
✅ TypeScript Compilation - All files compile successfully with TypeScript 6.0.2

tests/ - No errors
scripts/ - No errors
dashboard/ - No errors
✅ ESLint 10 - Linting works correctly with new version

Only 13 pre-existing warnings about any types in scripts/
ESLint 10's import-x plugin working properly
FileEnumerator API warning suppression configured correctly
✅ Unit Tests (Jest + ts-jest 29.4.9)

69 test suites passed
1,692 tests passed
68 snapshots passed
✅ Vitest Tests (scripts directory)

27 test files passed
452 tests passed
⚠️ Integration Tests - 42 tests failing in azure-deploy

These failures are pre-existing (verified by testing main branch)
Same failures occur on main branch
Not related to the TypeScript/ESLint upgrade
Conclusion:
The TypeScript 6.0.2, ESLint 10, and related dependency upgrades are working perfectly. All compilation, linting, and test infrastructure is functioning correctly with the new versions. The branch is ready to merge! 🚀

Pull request overview

Modernizes the repo’s TypeScript + lint/test toolchain to support TypeScript 6.x (notably aligning ts-jest with the expanded TS peer range) and updates ESLint configuration to use the maintained eslint-plugin-import-x fork for ESLint 10 compatibility.

Changes:

• Bump TypeScript to 6.0.2 across packages and upgrade ts-jest in tests/ to a TS 6–compatible version.
• Upgrade tests/ lint stack to ESLint 10 and switch from eslint-plugin-import to eslint-plugin-import-x (+ add TS resolver).
• Add explicit Node typings in scripts/tsconfig.json to restore node:* import / NodeJS.* namespace type resolution under TypeScript 6.
