The data/countries/ directory provides a minimal dataset of countries used to power both map-based and list-based components in the application. It merges geographic metadata with human-readable names to support UI interactions.

Purpose

This module is responsible for parsing and exposing a list of countries derived from the countries.geo.json file. It extracts:

• ISO 3166-1 alpha-3 codes (e.g., USA, FRA)
• Common names (e.g., “United States”, “France”)

This ensures consistent identification of countries across both the map (CountriesLayer) and UI controls like CountrySelector.

Contents

countries.geo.json

• A GeoJSON file with country shapes and properties, including ISO alpha-3 identifiers and names.

  Source: mapsam/gist

countries.ts

• A script that processes the raw GeoJSON and exposes a clean list of { code, name } objects. These are used throughout the app as the canonical country reference.

Output Format

Each entry in the exported countries array has the shape:

{
  code: 'BRA',       // ISO alpha-3 code (uppercase)
  name: 'Brazil'     // Common English name
}
