@squawk/icao-registry

Resolves a 24-bit ICAO hex address to its aircraft registration and info. Pure logic library - contains no bundled data. Accepts an array of AircraftRegistration records at initialization. For zero-config use, pair with @squawk/icao-registry-data. Includes FAA ReleasableAircraft ZIP parsing utilities for consumers who want to fetch their own fresh data.

Documentation

Part of the @squawk aviation library suite. See all packages on npm.

Installation

npm install @squawk/icao-registry

Usage

With bundled data (zero-config)

npm install @squawk/icao-registry-data
Copy

import { usBundledRegistry } from '@squawk/icao-registry-data';
import { createIcaoRegistry } from '@squawk/icao-registry';

const registry = createIcaoRegistry({ data: usBundledRegistry.records });
const aircraft = registry.lookup('A004B3');
Copy

With fresh FAA data

import { createIcaoRegistry, parseFaaRegistryZip } from '@squawk/icao-registry';

const zipBuffer = await fetch('https://registry.faa.gov/database/ReleasableAircraft.zip').then(
  (r) => r.arrayBuffer(),
);
const data = parseFaaRegistryZip(Buffer.from(zipBuffer));
const registry = createIcaoRegistry({ data });
Copy

With custom data

import { createIcaoRegistry } from '@squawk/icao-registry';

const registry = createIcaoRegistry({
  data: [{ icaoHex: 'A00001', registration: 'N12345', make: 'CESSNA', model: '172S' }],
});
Copy

Browser / SPA usage

For SPAs and edge runtimes, import from the /browser subpath. It re-exports createIcaoRegistry and the shared types but omits parseFaaRegistryZip, which depends on Node's Buffer and the adm-zip package and is unsuitable for browser bundles. Pair it with @squawk/icao-registry-data/browser:

import { loadUsBundledRegistry } from '@squawk/icao-registry-data/browser';
import { createIcaoRegistry } from '@squawk/icao-registry/browser';

const dataset = await loadUsBundledRegistry();
const registry = createIcaoRegistry({ data: dataset.records });
Copy

Browser consumers that need fresh FAA data should fetch and parse the ZIP server-side (where parseFaaRegistryZip is available) and feed the resulting records into the browser via their own API.

API

• createIcaoRegistry({ data }) - builds a registry from an array of AircraftRegistration records.
• registry.lookup(icaoHex) - resolves a 24-bit ICAO hex address to a record, or undefined.
• registry.recordCount - total number of records in the loaded dataset.
• parseFaaRegistryZip(buffer) - parses a downloaded FAA ReleasableAircraft.zip into the AircraftRegistration[] shape that createIcaoRegistry expects. Node-only; not exported from the /browser entry.

Under active development. See the docs for current API status.
