Introduction

HPS (@hyperse-io/hps) is the next-generation build tool designed for modern web apps. Built on Rspack, it delivers instant startup, lightning-fast HMR, and minimal-config deployment.

Three-Tier Architecture

The HPS system follows a clear separation of concerns across three architectural layers:

Layer	Purpose	Package Pattern	Examples
CLI	User interface, command orchestration	@hyperse/hps	Core CLI, command parsing
Plugin	Feature implementation	@hyperse/hps-plugin-*	build, serve, mock, deploy, update, info, pack
Service	Technical implementation	@hyperse/hps-srv-*	rspack, rolldown, mock, ts-checker, common

Each layer has well-defined responsibilities and dependencies flow downward: CLI depends on Plugins, Plugins depend on Services.
