openweathermap-ts

An abstract layer over openWeatherMap APIs to simplify making calls. Built with TypeScript and Promises. Even the returned JSON responses are typed for your benefits!

Note: The library currently only supports free tier API services:

• Current Weather
• 3-hour Forecast. (5 day / 3 hour)

Installation

// install using npm
npm install openweathermap-ts

You will also need to register for an API key at the official site.

Basic Setup

const OpenWeatherMap = require('openweathermap-ts');
// or
import OpenWeatherMap from 'openweathermap-ts';

const openWeather = new OpenWeatherMap({
  apiKey: 'Your API Key'
});

Usage

There are 2 ways of using public getter methods.

• Pass in argument/s
• Store preferences in the location object

When both are used, the argument/s precede over the defined location object.

Notice some methods are grouped together with & because their arguments are the same. But they produce different results.

getCurrentWeatherByCityName & getThreeHourForecastByCityName

/**
 * @param {
 *  cityName: string,
 *  state?: string, // Spell it out. E.g, Texas
 *  countryCode?: CountryCodeType
 * }
 */
openWeather
  .getCurrentWeatherByCityName({
    cityName: 'Cedar Park'
  })
  .then((weather) => console.log('Weather object is', weather));

// or async await example
try {
  const weather = await openWeather.getThreeHourForecastByCityName({
    cityName: 'Cedar Park',
    state: 'Texas',
    countryCode: 'US'
  });
  console.log('Weather object is', weather);
} catch (error) {
  console.error('Error is ', error);
}

getCurrentWeatherByCityId & getThreeHourForecastByCityId

/**
 * @param cityId: number
 */
openWeather
  .getCurrentWeatherByCityId(1835848)
  .then((weather) => {
    console.log('Weather object is', weather);
  })
  .catch((error) => console.error('Error is ', error));

Or

// set the cityId in location object
openWeather.setCityId(1835848);

// invoke the method without an argument
openWeather
  .getThreeHourForecastByCityId()
  .then((weather) => {
    console.log('Weather object is', weather);
  })
  .catch((error) => console.error('Error is ', error));
