Shared utilities — type predicates, promise helpers, object tools, data structures

Part of the Omni monorepo — Fullstack Type-Safe RPC Framework.

Installation

pnpm add @omnitron-dev/common

Overview

A comprehensive utility library providing type-safe primitives for everyday TypeScript development. Works in both Node.js and Bun.

What's Inside

• Type predicates — isString, isNumber, isPlainObject, isNil, isPromise, 50+ more with proper type narrowing
• Promise utilities — defer, delay, timeout, retry (with backoff), props, promisify/callbackify
• Object utilities — omit (deep, path-based, predicate), entries/keys/values with options
• Data structures — ListBuffer (O(1) queue), TimedMap (auto-expiring cache)
• Primitives — noop, identity, truly, falsely, arrify
• Platform detection — isWindows, darwin, linux, isNodejs

Quick Start

import { isString, delay, omit, retry } from '@omnitron-dev/common';

if (isString(value)) {
  console.log(value.toUpperCase()); // narrowed to string
}

await delay(1000);

const safe = omit(user, ['password', 'ssn']);

const data = await retry(() => fetch('/api'), { max: 3, backoffBase: 1000 });
