#What is UtilCN?

UtilCN is a clean, modern utility library built exclusively for TypeScript developers who want reliable, type-safe helpers without the bloat of larger frameworks. Launched in 2025, it serves as a centralized registry of battle-tested functions that solve common programming problems—think data transformation, input sanitization, object manipulation, and more. Whether you're working on a React frontend, a Next.js app, or a Node.js backend, UtilCN integrates smoothly by letting you import only what you need. Unlike general-purpose libraries, every function is written with TypeScript in mind, offering full autocomplete, type inference, and compile-time safety. It’s ideal for solo developers, startups, or teams aiming to maintain consistency and reduce bugs in shared codebases.

#Features ⚡️

• Type-Safe by Design: Every utility uses generics, overloads, and precise return types to catch errors during development.

• Modular and Tree-Shakable: Import individual functions to keep bundle sizes minimal.

• No Dependencies: Pure TypeScript implementation works anywhere—browser, server, or Deno.

• Performance-First: Lightweight functions optimized for speed and memory efficiency.

• Developer-Friendly: Clear naming, intuitive APIs, and practical defaults for real-world use.

• Extensible: Open structure invites community contributions and custom extensions.

#Pros ✅

• Eliminates Repetition: Replace one-off helpers with standardized, trusted implementations.

• Full TypeScript Support: Autocomplete and error detection make development faster and safer.

• Zero Bloat: No unnecessary features or runtime weight—just the tools you actually use.

• Free Forever: MIT license means unrestricted use in personal and commercial projects.

• Easy to Adopt: Copy-paste or import; no complex setup or configuration required.

#Cons ⚠️

• Early-Stage Project: Documentation and examples are still growing; some advanced use cases may lack guidance.

• Limited Ecosystem: Not yet widely known, so community support and third-party resources are minimal.

• No Built-in CLI: Unlike some UI libraries, installation relies on manual imports or npm (if published).

• Narrow Focus: Sticks to core utilities—won’t replace specialized tools like validation schemas or date libraries.

#Included Components - Templates

UtilCN organizes utilities into logical groups for easy discovery and use:

• String Tools: Format, slugify, truncate, capitalize, and safely escape user input.

• Array Helpers: Chunk, shuffle, unique, group by key, and deep filtering with type preservation.

• Object Utilities: Deep merge, pick/omit properties, safe navigation, and structured cloning.

• Validation Functions: Check emails, URLs, numbers, and custom patterns with descriptive errors.

• Functional Aids: Debounce, throttle, compose, and memoize with full type inference.

• Async Support: Promise wrappers, retry logic, and timeout handlers for robust control flow.

Each function is standalone, so you only bring in what your project needs.

#Pricing 💸

UtilCN is completely free and open-source under the MIT license. There are no paid tiers, subscriptions, or premium features. All current and future utilities are available at no cost, with optional community sponsorships to support ongoing development.

#Integrations 🧰

UtilCN works anywhere TypeScript does:

• React, Next.js, and Vue (with TypeScript) for frontend logic.

• Node.js and Express for backend utilities and middleware.

• Testing frameworks like Jest and Vitest for typed mocks and assertions.

• Build tools including Vite, Webpack, and esbuild via ES modules.

• Complements Zod, Yup, or Joi for validation-heavy applications.
