NestJS 12 Unblocks Modern JavaScript with Native ESM Support

NestJS 12 introduces native ESM support, finally bridging the CommonJS vs. ESM divide that has fragmented the Node.js ecosystem. While raw performance metrics show no measurable difference, the real value lies in enabling seamless integration with the modern JavaScript backend ecosystem that has already shifted to ESM. This architectural shift removes friction from tooling and monorepo setups, allowing developers to build full-stack applications on a unified module system.
