@lacspace/validate

v1.1.0App & Utils Kit0 deps

A tiny, typed schema validator with Zod-style ergonomics — parse/safeParse, objects/arrays/tuples, unions & discriminated unions, records/maps/sets, recursive (lazy) schemas, coercion, refinements/transforms/pipes, and nested form-error formatting, all fully type-inferred. Zero-dependency, isomorphic.

Usage

validate.ts
import { v, type Infer } from "@lacspace/validate";

const User = v.object({
  name: v.string().min(2).trim(),
  email: v.string().email().toLowerCase(),
  age: v.coerce.number().int().min(0).optional(),
  role: v.enum(["admin", "user"]).default("user"),
  tags: v.array(v.string()).max(10).default([]),
});

type User = Infer<typeof User>;
//   ^ { name: string; email: string; role: "admin" | "user"; tags: string[]; age?: number }

User.parse(input);      // ✅ returns typed data, or throws ValidationError
User.safeParse(input);  // ✅ { success: true, data } | { success: false, error }

More in App & Utils Kit

@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/form

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.
