Usage

Basic Setup

You can now use the HKJC API in two ways:

Simplified Setup (Recommended)

import { HorseRacingAPI, FootballAPI } from 'hkjc-api';

// Initialize APIs directly - client is created automatically
const horseRacingAPI = new HorseRacingAPI();
const footballAPI = new FootballAPI();

Advanced Setup (Custom Client)

import { HKJCClient, HorseRacingAPI, FootballAPI } from 'hkjc-api';

// Create a custom client if needed
const client = new HKJCClient();

// Initialize APIs with the custom client
const horseRacingAPI = new HorseRacingAPI(client);
const footballAPI = new FootballAPI(client);

Horse Racing API

Get Race Meetings

// Get only active meetings
const activeMeetings = await horseRacingAPI.getActiveMeetings();

// Get all race meetings (includes race details)
const raceMeetings = await horseRacingAPI.getAllRaces();

Get Race Information

// Get all races
const races = await horseRacingAPI.getAllRaces();

// Get a specific race (default is race 1)
const race = await horseRacingAPI.getRace(3); // Get race #3

// Get a specific race with date and venueCode (default is race 1)
const race = await horseRacingAPI.getRaceWithDateAndVenueCode('2026-01-26' , 'ST', 3); // Get race #3

Get Race Runners

// Note: Runner information is included in the race data from getAllRaces() or getRace()
// Access runners through the race object's runners property
const race = await horseRacingAPI.getRace(1);
const runners = race?.runners || [];

Get Race Odds

// Get odds for a specific race and odds types
const oddsResult = await horseRacingAPI.getRaceOdds(
  1,                      // Race number (defaults to 1)
  ['WIN', 'PLA', 'QIN']   // Odds types (defaults to ['WIN', 'PLA'])
);

// Get odds for a specific date and venue race with and odds types
const oddsResult = await horseRacingAPI.getRaceOddsWithDateAndVenueCode(
  '2026-01-24',
  'S2',
  1,                      // Race number (defaults to 1)
  ['WIN', 'PLA', 'QIN']   // Odds types (defaults to ['WIN', 'PLA'])
);

// Get pool investment data
const poolsResult = await horseRacingAPI.getRacePools(
  1,                      // Race number (defaults to 1)
  ['WIN', 'PLA']          // Odds types (defaults to ['WIN', 'PLA'])
);

// Get the pool investment data of the specific date and venue race
const poolsResult = await horseRacingAPI.getRacePoolsWithDateAndVenueCode(
  '2026-01-24',
  'S2',
  1,                      // Race number (defaults to 1)
  ['WIN', 'PLA']          // Odds types (defaults to ['WIN', 'PLA'])
);

Football API

Get All Football Matches

// Get all football matches
const allMatches = await footballAPI.getAllFootballMatches();

// Get matches with filters
const filteredMatches = await footballAPI.getAllFootballMatches({
  startDate: '2025-04-30',
  endDate: '2025-05-07',
  tournIds: ['50046423'],          // Tournament IDs
  oddsTypes: ['HAD', 'CRS', 'HHA'], // Odds types
  featuredMatchesOnly: true        // Only featured matches
});

// Get details for a specific match
const matchDetails = await footballAPI.getFootballMatchDetails('50047131');

Examples

Horse Racing Example

// Simplified usage - no need to create a client instance
const { HorseRacingAPI } = require('hkjc-api');
const horseAPI = new HorseRacingAPI();

// Get active meetings
const activeMeetings = await horseAPI.getActiveMeetings();
console.log(`Found ${activeMeetings.length} active meetings`);

// Get today's race information
const races = await horseAPI.getAllRaces();
console.log(`Found ${races[0]?.races.length || 0} races today`);

// Get WIN and PLA odds for race #1
const raceOdds = await horseAPI.getRaceOdds(1, ['WIN', 'PLA']);
console.log(`WIN/PLA odds for race #1:`, raceOdds);

Football Example

// Simplified usage - no need to create a client instance
const { FootballAPI } = require('hkjc-api');
const footballAPI = new FootballAPI();

// Get all matches
const matches = await footballAPI.getAllFootballMatches();
console.log(`Found ${matches.length} football matches`);

// Get details for the first match
if (matches.length > 0) {
  const matchId = matches[0].id;
  const matchDetails = await footballAPI.getFootballMatchDetails(matchId);
  
  console.log(`Match: ${matchDetails.homeTeam.name_en} vs ${matchDetails.awayTeam.name_en}`);
  console.log(`Date: ${matchDetails.matchDate}`);
  console.log(`Kick-off: ${matchDetails.kickOffTime}`);
}

Error Handling

Both APIs include proper error handling. Methods will return null or empty arrays when data is not found, and will throw exceptions for API errors.

try {
  const match = await footballAPI.getFootballMatchDetails('invalid-id');
  if (match === null) {
    console.log('Match not found');
  }
} catch (error) {
  console.error('API error:', error);
}
