Static Data Kit

A TypeScript-first utility library for accessing and using high-quality static reference data in SaaS, B2B, and analytics applications.

✨ Why Static Data Kit?

When building SaaS platforms, you often need consistent, high-quality static data for:

• Countries
• Currencies
• States or provinces
• Job roles and industries
• Regional formats

But existing datasets are often:

• Incomplete or poorly structured
• Behind paywalls or APIs
• Unreliable or inconsistently formatted

Static Data Kit solves this by offering a clean, typed, offline-friendly dataset with standardized fields — perfect for use in onboarding flows, settings screens, or seed data in any modern app.

📦 Installation

npm install @financially/static-data-kit
# or
yarn add @financially/static-data-kit
# or
pnpm add @financially/static-data-kit

const all = getAllRegionalSettings();

📘 Interface

export interface RegionalSetting {
  countryCode: string;
  dateFormat: DateFormat;
  timeFormat: TimeFormat;
  weekStartsOn: WeekStart;
  defaultTimeZone: string; // e.g. "Asia/Phnom_Penh"
  numberFormat: {
    format: string; // e.g. "comma-thousand-dot-decimal"
    example: string; // e.g. "1,234.56"
    groupingStyle: number[]; // e.g. [3]
    decimalSeparator: string; // e.g. "."
    thousandSeparator: string; // e.g. ","
  };
}

All the timezone values are used according to proper ISO format. We use the package: https://github.com/vvo/tzdb/

🧪 Type Safety

All datasets are fully typed with TypeScript. You get complete IntelliSense, validation, and autocomplete support out-of-the-box.

📁 Asset Access (Flags)

All country flags are stored as SVGs with filenames like:

IN.svg
US.svg
...

Each country object includes a flagFile field:

"flagFile": "IN.svg"

You can use this to construct the full flag URL using your own asset CDN or static hosting service.

✅ Usage Example

import { getCountryByAlpha2Code } from '@financially/static-data-kit';

const CDN_BASE_URL = 'https://assets.your-domain.com/countries/';
const country = getCountryByAlpha2Code('IN');

const flagFile = `${CDN_BASE_URL}${country.flagFile}`;
console.log(flagFile);
// Output: https://assets.your-domain.com/countries/IN.svg

🤝 Contributing

PRs are welcome! Please follow these guidelines:

• Keep entries alphabetically sorted where appropriate
• Ensure field consistency and valid JSON
• Add new types to src/types/index.ts
• Store new country flags in src/assets/countries/XX.svg

See CONTRIBUTING.md for more details.
