@data-sets

A monorepo of static, curated data-sets for Node.js. Each package ships a JSON data file, ESM lookup functions, and TypeScript type declarations.

Package	Description	Records
@data-sets/countries	ISO 3166 countries	~190
@data-sets/currencies	ISO 4217 currencies	154
@data-sets/pokemon	Gen 1 Pokemon (#001-#151)	151

Install

Each package is published independently:

pnpm add @data-sets/countries
pnpm add @data-sets/currencies
pnpm add @data-sets/pokemon

Quick Start

Every package exports a data array and a set of lookup functions:

import { findByCode } from '@data-sets/countries';
const gb = findByCode('GB');

import { findByCode as findCurrency } from '@data-sets/currencies';
const usd = findCurrency('USD');

import { findById } from '@data-sets/pokemon';
const pikachu = findById(25);

Lookups by primary key (findByCode, findById) are O(1) via pre-built Map indexes. Filter-style lookups (findByContinent, findByType, findByCountry) use Array.filter.

See each package's README for the full API and data shape.
