@dirstack/utils

A lightweight, dependency-light set of TypeScript utilities shared across projects. Tree-shakeable, ESM-first (with a CommonJS build), and fully typed.

Install

bun add @dirstack/utils
# or: npm install @dirstack/utils

Usage

Everything is exported from the package root:

import{chunk,clamp,formatBytes,slugify,tryCatch}from"@dirstack/utils"chunk([1,2,3,4,5],2)// [[1, 2], [3, 4], [5]]clamp(12,0,10)// 10formatBytes(1536,1)// "1.5 KB"slugify("Hello World")// "hello-world"const{ data, error }=awaittryCatch(fetch("/api"))

What's inside

ModuleHighlights
arrayuniq, uniqBy, chunk, groupBy, keyBy, countBy, compact, sortBy, sum, sumBy, range
batchprocessBatch, processBatchWithErrorHandling (ordered, concurrency-limited, with onProgress)
colorsisLightColor
domgetElementPosition, getShortcutLabel, toBase64, setInputValue
errorsisErrorWithMessage, toErrorWithMessage, getErrorMessage
eventssubscribe, unsubscribe, publish, publishEscape
formatformatNumber, formatCurrency, formatBytes, formatMimeType, isMimeTypeMatch
helperssleep, isTruthy, tryCatch, debounce, throttle, retry
httpisValidUrl, normalizeUrl, getDomain, joinUrlPaths, query-param helpers, checkUrlAvailability
numbersclamp, parseNumericValue, preciseRound
objectspick, omit, isEmptyObject, sortObject, nullsToUndefined
paginationgetCurrentPage, getPageParams, getPageLink
parsersmaybeParseJson, maybeStringifyJson, serialize, deserialize
randomgetRandomColor, getRandomString, getRandomNumber, getRandomElement
stringucFirst, lcFirst, stripHtml, getExcerpt, slugify, getInitials, joinAsSentence
timeformatDate, formatTime, formatDateTime, formatDateRange, getReadTime

Some utilities (dom, events, toBase64, setInputValue) rely on browser APIs and are only usable in the browser.
