Reviewgenerated from repository data · Aug 5, 2026

What it is

Nestia is a set of helper libraries for NestJS, supporting features across multiple packages: @nestia/core with decorators and WebSocket support; @nestia/sdk with Swagger generation, client SDKs, a mockup simulator, and E2E test function generation; @nestia/e2e, @nestia/benchmark, @nestia/editor; and integration with @agentica for LLM function calling and other tooling. The project includes a CLI tool nestia.

How it works

The toolkit provides typed fetch functions and DTO structures for SDK usage, a runtime validator with performance characteristics claimed in notes, and a mockup simulator for client applications. It emphasizes TypeScript typing and NestJS compatibility, with Swagger-related tooling and E2E testing support.

Getting started

The repository README shows guidance through a documentation website: "Check out the document in the website". It also highlights setup and pure TypeScript usage in the features section:

Dragon notes emphasize: "Only one line required, with pure TypeScript type".

Exact commands to run are not included in the truncated README excerpt provided here, but the project is published as an SDK and tooling for NestJS with TypeScript types.
