toolkit

toolkit is a developer-friendly TypeScript utility library with small,
well-typed helpers for common tasks. It’s designed to reduce boilerplate,
stay out of your way, and feel natural to use in everyday projects.

Getting Started

You can install this application from npm or jsr.

# recommended if using NodeJS
npx jsr add @bytebury/toolkit

# good, old-fashion npm
npm install @bytebury/toolkit --save

# or, if you're using Deno
deno add jsr:@bytebury/toolkit

Sample Usage

import { average, isNoneOrWhitespace, title } from "@bytebury/toolkit";

function sayHelloTo(name: string): void {
  if (isNoneOrWhitespace(name)) {
    console.log("Hello, Guest!");
  } else {
    console.log(`Hello, ${title(name)}!`);
  }
}

function getAverageAge(): number {
  const people = [
    { name: "Tom", age: 2 },
    { name: "Carly", age: 8 },
    { name: "Jenny", age: 5 },
  ];
  return average(people.map(({ age }) => age)); // 5
}

Naming Notes

Helpers such as isWhitespace and isEmpty are already null and undefined safe. The more explicit isNoneOrWhitespace, isNoneOrEmpty, isNotNoneOrWhitespace, and isNotNoneOrEmpty aliases are available when that behavior should be visible at the call site.
