🧠🚀 Announcing helper-utils-ts — A Lightweight Utility Library for Clean Value Checks

Hey folks 👋

I recently published a small npm package called helper-utils-ts, and I wanted to share it with the community here on DEV. It solves something many of us run into pretty often — repetitive checks for null, undefined, and empty values scattered all over the codebase.

Why this library?

In multiple projects, I noticed I kept writing variations of:

if (value !== null && value !== undefined && value !== "") {
   // do something
}

This gets messy fast — especially in TypeScript projects where cleaner, readable checks are important.

So I extracted the checking logic into small reusable helpers and released them as a package.

No dependencies.
No setup.
Just simple helpers.

📦 Installation
npm install helper-utils-ts

Or if you're installing globally:
npm install -g helper-utils-ts

🧑‍💻 Usage Example

import { isUndefined, isNull, isEmpty } from "helper-utils-ts";

let foo;
console.log(isUndefined(foo)); // true

console.log(isNull(null)); // true

console.log(isEmpty("")); // true
console.log(isEmpty("null")); // true
console.log(isEmpty("undefined")); // true

🔍 How this differs from Lodash (and others)

Libraries like Lodash are extremely powerful, but they’re also large and general-purpose.

This package has a very focused goal:

• Only handles value validation checks
• Very small footprint
• TypeScript-native with clean typings
• Handles real-world edge cases (like "null" string from user input)

If you just need small readability helpers — this fits well.

If you're building full data pipelines — you probably want Lodash or Ramda.

🎯 Where this helps most

• Input validation (frontend or backend)
• Normalizing API or JSON payload values
• Form processing and sanitization
• Serverless / microservice environments where bundle size matters
• Beginner-friendly or clarity-focused codebases

💬 Feedback appreciated!

This library is intentionally minimal — but it can grow if the community finds other practical helper patterns worth adding. Suggestions are welcome 🙌
