Upgrade TypeScript to 5.2.2 and add @types/node for Node v20 compatibility

[Copilot]

Resolves TypeScript compilation errors from missing Node v20 type definitions: esnext.disposable lib, asyncDispose/dispose on SymbolConstructor, Disposable/AsyncDisposable interfaces, and TextEncoder incompatibilities.

Changes

Dependency upgrades across all packages:

• TypeScript: ^4.9.x → 5.2.2
• Added @types/node: ^20.11.0
• Added tslib: ^2.6.0 (required by TypeScript's importHelpers)

Configuration cleanup:

• Removed deprecated suppressImplicitAnyIndexErrors from all tsconfig.json files (no longer supported in TS 5.5+)
• Updated test expectations for tsconfig parsing

Files modified:

• package.json, shared/package.json, ts-plugin/package.json, eslint-ts-plugin/package.json
• All tsconfig.json and tsconfig.test.json files
• shared/test/src/tsConfigDetails.test.ts

Note

The eslint-ts-plugin has separate compilation errors from @types/eslint type changes unrelated to this Node.js type upgrade.

Original prompt

Problem

The build is failing with TypeScript compilation errors related to @types/node compatibility issues. The errors include:

• Missing lib definition for 'esnext.disposable'
• Properties like asyncDispose and dispose not existing on SymbolConstructor
• Missing type definitions for Disposable and AsyncDisposable
• Interface incompatibilities with TextEncoder

Solution

Upgrade TypeScript to version 5.2.2 and the corresponding compatible @types/node version to resolve these type errors.

Files to Update

Update the following package.json files:

1. Root package.json

• Update typescript from ^4.9.5 to 5.2.2
• Add @types/node as a devDependency with version ^20.11.0 (compatible with Node v20 and TypeScript 5.2.2)

2. shared/package.json

• Update typescript from ^4.9.4 to 5.2.2
• Add @types/node as a devDependency with version ^20.11.0

3. ts-plugin/package.json

• Update typescript from ^4.9.4 to 5.2.2
• Add @types/node as a devDependency with version ^20.11.0

4. eslint-ts-plugin/package.json

• Update typescript from ^4.9.4 to 5.2.2
• Add @types/node as a devDependency with version ^20.11.0

Expected Changes

All package.json files should have:

{
  "devDependencies": {
    "typescript": "5.2.2",
    "@types/node": "^20.11.0"
  }
}

This will ensure all packages use the same TypeScript version and have proper Node.js type definitions that support the newer TypeScript features including disposable symbols and async disposables.
