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.

1. Pass in argument/s
2. 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({
