@knitkode/utils

Tree-shakeable TypeScript utilities for everyday web development: type guards, object and array helpers, string case conversion, URL, cookie and timing helpers. It also re-exports type-fest types.

Install

pnpm add @knitkode/utils
# or: npm install @knitkode/utils
Copy

Usage

import { changeCaseCamel, debounce, isFullString, objectPick, slugify } from "@knitkode/utils";

slugify("Hello World"); // "hello-world"
changeCaseCamel("hello world"); // "helloWorld"
objectPick({ a: 1, b: 2, c: 3 }, ["a", "c"]); // { a: 1, c: 3 }

const onResize = debounce(() => console.log("resized"), 200);

function greet(name: unknown) {
  if (isFullString(name)) return `Hello ${name}`; // `name` is narrowed to `string`
}
Copy

Entry points

Import from @knitkode/utils, or from one subpath per module to load only that module, e.g. @knitkode/utils/slugify.

The ambient helper types (Tweak, AssertTrue, ...) are opt-in:

/// <reference types="@knitkode/utils/typings" />
Copy

Requirements

ES modules only, with TypeScript declarations included. Use "moduleResolution": "bundler", "node16" or "nodenext" in TypeScript projects. See the repository README.
