Basic Usage

const {
  getAirportByIata,
  getAirportByIcao,
  searchByName,
  findNearbyAirports
} = require('airport-data-js');

// Get airport by IATA code
const [airport] = await getAirportByIata('SIN');
console.log(airport.airport); // "Singapore Changi Airport"

// Get airport by ICAO code
const [airport] = await getAirportByIcao('WSSS');

airports.forEach(airport => {
  if (airport) {
    console.log(`${airport.iata}: ${airport.airport}`);
  }
});

// Calculate distance matrix for route planning
const matrix = await calculateDistanceMatrix(['SIN', 'LHR', 'JFK']);
console.log(`Distance from SIN to LHR: ${matrix.distances.SIN.LHR} km`);
console.log(`Distance from LHR to JFK: ${matrix.distances.LHR.JFK} km`);

Validation utilities

// Validate airport codes before processing
const codes = ['SIN', 'XYZ', 'LHR', 'ABCD'];
for (const code of codes) {
  const isValid = await validateIataCode(code);
  console.log(`${code}: ${isValid ? 'Valid' : 'Invalid'}`);
}

// Check if airport is operational
const operational = await isAirportOperational('SIN');
console.log(`Singapore Changi is operational: ${operational}`);

Find nearest airport

// Find nearest airport to current location
const nearest = await findNearestAirport(1.35019, 103.994003);
console.log(`Nearest airport: ${nearest.airport} (${nearest.distance} km away)`);

// Find nearest large airport with scheduled service
const nearestHub = await findNearestAirport(1.35019, 103.994003, {
  type: 'large_airport',
  has_scheduled_service: true
});

Development Workflow

1. Create a branch from main for your changes
2. Make your changes in src/index.js or data/airports.json
3. Add or update tests in tests/index.test.js
4. Run tests to make sure everything passes: npm test
5. Build to verify the bundles compile: npm run build
6. Submit a pull request against main

Updating Airport Data

If you are adding or updating airport entries:

1. Edit data/airports.json directly
2. Run npm run check:duplicates to ensure no duplicate IATA/ICAO codes
3. Run node scripts/compress_json.js to regenerate the compressed dataset
4. Run npm test to verify the changes
5. Submit a pull request with both the JSON and compressed data changes

Publishing a New Version

Releases are automated via the release workflow. To publish a new version:

1. Update the version in package.json (follow Semantic Versioning)
2. Update CHANGELOG.md with a new section for the version (follow Keep a Changelog format)
3. Build and test locally to confirm everything works:

   npm run build && npm test

4. Commit your changes to main
5. Push or merge to the release branch -- this triggers the CI pipeline which will:
   • Run tests across Node.js 20.x, 22.x, and 24.x
   • Run a security audit (npm audit --audit-level=critical)
   • Check for duplicate airport codes
   • Build the package
   • Compare the version in package.json against the published npm version
   • Publish to npm with provenance (if the version is new)
   • Create a GitHub Release with notes extracted from CHANGELOG.md

The workflow can also be triggered manually via workflow_dispatch from the Actions tab.

Version Policy

• Patch (e.g., 3.0.1 -> 3.0.2): Data updates, bug fixes, performance improvements, dependency bumps
• Minor (e.g., 3.0.x -> 3.1.0): New functions or non-breaking feature additions
• Major (e.g., 3.x.x -> 4.0.0): Breaking API changes or data format changes
