@lacspace/form

v1.1.0App & Utils Kit0 deps

End-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.

Usage

form.ts
// app/actions.ts
"use server";
import { createForm } from "@lacspace/form";
import { v } from "@lacspace/validate";

const contact = createForm({
  schema: v.object({
    name: v.string().min(2),
    email: v.string().email(),
    message: v.string().min(10),
  }),
  honeypot: "company",   // hidden field bots fill; humans never see it
  minSubmitMs: 800,      // reject sub-second (bot-speed) submissions
});

export async function submit(prev: unknown, formData: FormData) {
  const r = contact.action(prev, formData);
  if (!r.ok) return r;              // { errors, values } → re-render form
  await sendEmail(r.data);          // ✅ { name, email, message } fully typed
  return { ok: true as const };
}

@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.

@lacspace/case

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/color

Parse, 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/env

Typed, 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/flags

Feature 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/humanize

Turn 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.
