Utoo

Unified Toolchain: Open & Optimized

Utoo is a modern, high-performance frontend toolchain designed to provide a unified and optimized experience. It combines a fast package manager, a powerful bundler, and a flexible command system into a single, cohesive ecosystem.

💡 Why Utoo?

Feature	Description
Unified	One tool for package management, building, and workflow automation.
Performance	Core logic in Rust + Turbopack for extreme speed.
Compatible	Seamless migration with Webpack compatibility mode.
Universal	Run anywhere: Local, CI, or Browser (via WASM).

📦 Core Components

• utoo (alias ut): High-performance Rust package manager (Fast, Parallel, npm compatible).
• @utoo/pack: Next-gen bundler powered by Turbopack (HMR, TS/JSX, Less/Sass, and more).
• @utoo/pack-cli: Command-line interface for the bundler (dev server, build). A lightweight wrapper to run up commands — up is a shortcut alias for utoopack.
• @utoo/web: Web-compatible version of the toolchain (WASM, Browser-based bundling).

ut add lodash       # Add a package (or use `ut add`)
ut x create-react   # Execute a package (npx style, or use `ut x`)

Bundling via @utoo/pack-cli

utx up dev          # Start dev server with HMR
utx up build        # Production build
utx up build --webpack # Build using webpack.config.js
