SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides patterns and code snippets to build lightweight, dependency-free TypeScript tools and libraries, reducing bloat and improving performance.

Core Features & Use Cases

Zero Dependencies: Inline small utilities and use Node.js built-ins to avoid external package bloat.
Type Safety: Leverage advanced TypeScript features like const generics and conditional types for robust, type-safe code.
Composable Primitives: Build complex functionality by composing simple, single-purpose functions.
Use Case: When creating a new CLI tool, a small utility library, or refactoring existing code to remove unnecessary dependencies, these patterns will guide you to a more maintainable and efficient solution.

Quick Start

Use the lean-ts-patterns skill to inline a simple ANSI color utility function into your project.

FAQPage Schema

How do I build a TypeScript CLI tool without external dependencies?▼

To build a zero-dependency TypeScript CLI, inline small utilities and use native Node.js modules instead of pulling external packages, composing simple single-purpose functions for maintainability and performance.

What is the best way to refactor TypeScript code to remove unnecessary libraries?▼

Refactoring TypeScript to remove libraries involves inlining small utilities and leveraging built-in Node.js modules to eliminate external package bloat while maintaining robust, type-safe code through advanced type system features.

How do advanced TypeScript features like const generics improve utility library maintainability?▼

Advanced TypeScript features like const generics and conditional types improve utility library maintainability by enforcing strict type safety, allowing you to build composable primitives without relying on external dependencies.

When should I use zero-dependency patterns for infrastructure code?▼

Use zero-dependency patterns for infrastructure code when creating new CLI tools, building small utility libraries, or refactoring existing projects to reduce bloat and improve performance without adding external packages.

Can I use native Node.js modules instead of external utility packages in TypeScript?▼

Yes, you can use native Node.js modules instead of external utility packages in TypeScript to construct lightweight, dependency-free tools, composing complex functionality from simple, single-purpose functions.

What are the limitations of building zero-dependency TypeScript libraries?▼

Building zero-dependency TypeScript libraries requires manually inlining utilities and managing advanced type system features yourself, trading the convenience of external packages for reduced bloat and increased maintainability.
