NestJS, being a TypeScript-based framework, requires a compatible TypeScript version to function correctly. The compatibility depends on the specific version of NestJS being used. Ensuring the correct TypeScript version is crucial to avoid build or runtime errors.
General Compatibility Guidelines
For NestJS v10.x, the recommended TypeScript version is 5.2.x. This aligns with the framework's dependencies and ensures smooth integration with its features. Using a TypeScript version outside this range (e.g., 5.1.x or 5.3.x) may lead to issues such as compilation errors or dependency conflicts.
For example, if your package.json specifies:
"@nestjs/core": "^10.0.2","typescript": "~5.1.3"Copied!âś•CopyYou may encounter errors, as TypeScript 5.1.x is not fully compatible with NestJS v10.x. Upgrading to "typescript": "~5.2.2" resolves such issues.
