NestJS v12.0.0 will fully migrate to ESM, introduce Standard Schema support, and modernize the toolchain with Vitest and oxlint.
Understanding the architecture is key to a smooth setup. To simplify the process, consider your function app as having two distinct components: Azure Functions Host, which handles triggers and manages the function lifecycle, and the Worker process, where your application code resides running in a separate process with the preloaded OpenTelemetry SDK.
Package validation is the process of verifying that your library is correctly structured, configured, and ready to be consumed by others before you publish it. It's not about checking whether your logic works. That's what tests are for. It's about making sure your package metadata, entry points, module formats, and published files all line up so that consumers can install and use it without unexpected runtime errors.
