FMY Stack

A personal TypeScript toolkit monorepo with focused packages for core utilities, runtime validation, Svelte UI, Elysia applications, and Drizzle ORM workflows.

I built these packages to keep recurring product-system concerns explicit and testable without copying ad-hoc helpers between applications.

Packages

Package	Scope	Verification
@frankfmy/core	Dates, money, strings, phone normalization, business identifiers, collections, functions, IDs and cryptographic helpers	241 tests / 634 assertions
@frankfmy/validation	ArkType schemas for identity, accounts, money, passwords, pagination and common request contracts	46 tests / 72 assertions
@frankfmy/db-utils	Drizzle pagination, search, soft deletion, transaction retry, batch operations and seeding	48 tests / 80 assertions
@frankfmy/elysia-kit	Elysia application setup, auth helpers, errors, rate limiting, logging and response contracts	40 tests / 66 assertions
@frankfmy/ui	Svelte 5 + Tailwind components for forms, tables, pagination, overlays, feedback and themes	strict Svelte check, package build, and styles export consumer

Repository status

The source repository is public. The five workspace packages are versioned together at 1.1.2. Publication is allowed only from the immutable release workflow after the complete monorepo and coordinated tarball-consumer gates pass.

Quick start

git clone https://github.com/FrankFMY/fmy-stack.git
cd fmy-stack
bun install --frozen-lockfile
bun run verify

Examples

Core utilities

import {
  formatDateRU,
  formatMoneyRU,
  groupBy,
  validateINN,
} from "@frankfmy/core";

formatDateRU(new Date());
formatMoneyRU(1_234.56);
validateINN("7707083893");
groupBy(records, "status");

Validation

import {
  Email,
  INN,
  PasswordStrong,
  UserCreate,
} from "@frankfmy/validation";

const result = UserCreate({
  email: "user@example.com",
  password: "Example-Passphrase-2026!",
  firstName: "Example",
  lastName: "User",
});

Elysia

import {
  ApiError,
  authPlugin,
  createApp,
  rateLimiter,
  respond,
} from "@frankfmy/elysia-kit";

const app = createApp({ name: "Example API" })
  .use(authPlugin({ secret: process.env.JWT_SECRET! }))
  .use(rateLimiter({ max: 100, windowMs: 60_000 }))
  .get("/health", () => respond.success({ ok: true }))
  .listen(3000);

Drizzle

import {
  buildPaginatedResult,
  paginate,
  runTransactionWithRetry,
} from "@frankfmy/db-utils";

const page = await paginate(query, { page: 1, limit: 20 });
await runTransactionWithRetry(db, async (tx) => {
  // transaction-owned writes
});

Quality gates

bun run format:check
bun run lint
bun run check
bun run test
bun run build
bun run packages:check
bun audit

The current clean gate uses Bun 1.4, TypeScript 6, Svelte 5, Vite 8, Turbo 2, Drizzle ORM 0.45, and Elysia 1.4 with zero known dependency advisories.
