Pi Monorepo

A collection of tools for managing LLM deployments and building AI agents.

Packages

• @mariozechner/pi-ai - Unified multi-provider LLM API
• @mariozechner/pi-web-ui - Web components for building AI chat interfaces
• @mariozechner/pi-proxy - CORS proxy for browser-based LLM API calls
• @mariozechner/pi-tui - Terminal UI library with differential rendering
• @mariozechner/pi-agent - General-purpose agent with tool calling and session persistence
• @mariozechner/pi - CLI for managing vLLM deployments on GPU pods

Development

This is a monorepo using npm workspaces for package management and a dual TypeScript configuration for development and building.

Common Commands

# Install all dependencies
npm install

# Build all packages (required for publishing to NPM)
npm run build

# Clean out dist/ folders in all packages
npm run clean

# Run linting, formatting, and tsc typechecking (no build needed)
npm run check

# Run directly with tsx during development (no build needed)
cd packages/pods && npx tsx src/cli.ts
cd packages/agent && npx tsx src/cli.ts

Package Dependencies

The packages have the following dependency structure:

pi-tui -> pi-agent -> pi

When new packages are added, the must be inserted in the correct order in the build script in package.json.

TypeScript Configuration

The monorepo uses a dual TypeScript configuration approach:

• Root tsconfig.json: Contains path mappings for all packages, used for type checking and development with tsx
• Package tsconfig.build.json: Clean build configuration with rootDir and outDir, used for production builds

This setup allows:

• Type checking without building (npm run check works immediately)
• Running source files directly with tsx during development
• Clean, organized build outputs for publishing

Versioning

All packages use lockstep versioning - they share the same version number:

# Bump patch version (0.5.0 -> 0.5.1)
npm run version:patch

# Bump minor version (0.5.0 -> 0.6.0)
npm run version:minor

# Bump major version (0.5.0 -> 1.0.0)
npm run version:major

These commands automatically:

1. Update all package versions
2. Sync inter-package dependency versions
3. Update package-lock.json

Publishing

# Dry run to see what would be published
npm run publish:dry

# Publish all packages to npm
npm run publish
