@lacspace/cache
A tiny in-memory cache — LRU/LFU eviction, per-entry TTL, stale-while-revalidate, tag invalidation and hit/miss stats, plus wrap()/getOrSet()/memoize() to cache any async function with single-flight de-duplication. Zero-dependency, isomorphic.
npm i @lacspace/cacheUsage
import { createCache } from "@lacspace/cache";
const cache = createCache<User>({ max: 500, ttl: 60_000 });
cache.set("a", user);
cache.get("a"); // user (or undefined once expired)
cache.has("a"); // true
cache.size; // 1Exports 2

Convert strings between cases — camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, Title/Sentence/Header/Capital Case and more, with a unicode-aware word splitter, an opt-in acronym registry, and is<Case> detectors. Zero-dependency, isomorphic.
@lacspace/colorParse, convert, manipulate and check colours — hex/rgb/hsl/hsv/oklch plus 148 CSS names, lighten/darken/mix/invert/complement, tints/shades & colour-wheel harmonies, and WCAG contrast for accessible UIs. Zero-dependency, isomorphic.
@lacspace/envTyped, validated environment variables — declare a schema, validate at boot, get a typed frozen object or one clear aggregated error. Coercers for ports, URLs, durations, byte sizes, lists & enums, ${VAR} expansion, secret-redacted errors and non-throwing safe-parse. A zero-dependency t3-env / envalid alternative.
@lacspace/flagsFeature flags & A/B experiments with no SaaS and no infrastructure — deterministic percentage rollouts, targeting segments, weighted variants, kill switches and per-user QA overrides, with an explain() that tells you why each flag resolved. Synchronous, zero-dependency, isomorphic.
@lacspace/formEnd-to-end form handling — turn FormData into typed, validated, spam-guarded data on the server (Next.js Server Actions), and manage interactive form state on the client (values/errors/touched/dirty, sync+async validation, nested paths, field arrays). One framework-free, zero-dependency package.
@lacspace/humanizeTurn machine values into human-readable text — bytes, durations, relative time, ordinals, plurals, compact numbers, grammatical lists, number-to-words, Roman numerals and SI units. Zero-dependency, isomorphic — one typed package instead of a pile of tiny formatting libs.
