Utilities

A set of common JS functions for Node and browser.

Goals:

• Just work for most cases, not a general framework.
• No dependencies.
• High performance & less code.
• Write with latest ECMAScript.
• Tree-shakeable.
• No duplicated with FP libraries (lodash, underscore, etc.)
• Type-first, We don't check for parameters that don't match the type.

Install

This package is pure ESM, it cannot be require()'d from CommonJS.

pnpm i @kaciras/utilities

The package has 2 entry points. Most functions work for both, but there are still some differences:

• @kaciras/utilities/browser can be imported from any environment, also have functions work with DOM.
• @kaciras/utilities/node have no browser-specific functions, but add utilities for Node, it can only be used in NodeJS.

// Use in Node.
import { /* ... */ } from "@kaciras/utilities/node";

// Use in other environment.
import { /* ... */ } from "@kaciras/utilities/browser";

Develop
