broadutils

A comprehensive utility library covering a wide range of use cases for both browser and Node.js environments.

Features

• Environment-specific Builds: Optimised subpath exports for both browser and node.
• Modular Design: Import only what you need (e.g., 1n-broadutils/node/filesystem or 1n-broadutils/browser/math).
• Fully Typed: Built with TypeScript, providing excellent autocompletion and type safety.
• Isomorphic Core: Many utilities (math, timing, validate, data, misc) share a common API across environments.

Installation

You can install 1n-broadutils using npm, yarn, pnpm, bun, or jsr:

# npm
npm install 1n-broadutils

# yarn
yarn add 1n-broadutils

# pnpm
pnpm add 1n-broadutils

# bun
bun add 1n-broadutils

# jsr
npx jsr add @1natsie/broadutils

Structure & Exports

The library is split into two primary environments: ./browser and ./node. Each environment has its own set of utilities, and some utilities are shared between both environments.

Browser Exports

• 1n-broadutils/browser - Main entry point for browser utilities.
• 1n-broadutils/browser/canvas - Canvas utilities (resize, getImage, getImageData, cloneImageData, getDimensions, mirrorImageToCanvas, createContextSnapshot, applyContextSnapshot)
• 1n-broadutils/browser/data - Data utilities (array, base64, object, string, clone, convertToDataUrl, textEncoder, textDecoder)
• 1n-broadutils/browser/math - Math utilities (min, max, clamp, constrain, average, hcf, lcm, convert)
• 1n-broadutils/browser/misc - Miscellaneous utilities (noop, createDeferred, allowGC, preventGC)
• 1n-broadutils/browser/network - Network utilities (fetch)
• 1n-broadutils/browser/timing - Timing utilities (time, sleep, setImmediate, clearImmediate)
• 1n-broadutils/browser/validate - Validation utilities (assert, check, isNonNullable, nonNullable)
• 1n-broadutils/browser/types - Type definitions

Node.js Exports

• 1n-broadutils/node - Main entry point for Node utilities.
• 1n-broadutils/node/data - Data utilities
• 1n-broadutils/node/environment - Environment utilities (which, parseArgs)
• 1n-broadutils/node/filesystem - File system utilities (betterReadStream)
• 1n-broadutils/node/math - Math utilities
• 1n-broadutils/node/misc - Miscellaneous utilities
• 1n-broadutils/node/timing - Timing utilities (time, sleep)
• 1n-broadutils/node/validate - Validation utilities
• 1n-broadutils/node/types - Type definitions

Usage Examples

Node.js Environment Utilities

import { which } from "1n-broadutils/node/environment";

// Locate an executable in the system PATH
const nodePath = which("node");
console.log(nodePath); // e.g. /usr/bin/node

const multipleExes = which.many(["node", "npm"]);

Node.js Filesystem Utilities

import { betterReadStream } from "1n-broadutils/node/filesystem";

// Read a file using an async generator
for await (const chunk of betterReadStream("./large-file.txt", { chunkSize: 8192 })) {
  console.log(chunk.byteLength);
}

Isomorphic Math Utilities

// Import works from both browser or node entries
import { clamp, average, convert } from "1n-broadutils/browser/math";

const clamped = clamp(150, 0, 100); // 100
const avg = average([1, 2, 3, 4, 5]); // 3

Browser Canvas Utilities

import { resize, createContextSnapshot, applyContextSnapshot } from "1n-broadutils/browser/canvas";

const canvas = document.createElement("canvas");
const ctx = canvas.getContext("2d")!;

// Resize canvas to [width, height]
resize(canvas, [800, 600]);

// Save and restore context state easily
const snapshot = createContextSnapshot(ctx);
// ... draw things ...
applyContextSnapshot(ctx, snapshot);

Data Utilities

import { array, clone, string } from "1n-broadutils/node/data";

// Deep clone objects
const original = { a: 1, b: { c: 2 } };
const copied = clone(original);

Timing Utilities

import { time } from "1n-broadutils/node/timing";

// Measure execution time
const [duration, result] = time(() => {
  // expensive operation
  return 42;
});
console.log(`Execution took ${duration}ms`);
