Node Js Weather App

Node Js Weather App is a simple module for obtaining weather information.

Use as a CLI Tool

Prerequisite

You need to have NodeJS installed in your machine.

Add to CLI

• Clone the repository.
• Go to the repository folder and run the following command in your terminal:

npm link

Usage

Now you can just run the following in terminal:

weather

By default you'll get current weather of Dhaka City.

If you want to get weather of a different city, run:

weather -c CITY_NAME

Use as a Library

Installation

npm install nodejs-weather-app

Usage

This library exposes two methods:

• getWeather, which will return a Promise
• printWeather, which will show the output as a readable message

For example, you can use the library like this:

var nodejsWeatherApp = require('nodejs-weather-app');

nodejsWeatherApp.getWeather().then(val => {
	nodejsWeatherApp.printWeather(val);
});

If you don't specify any city and run the code, you will get Dhaka city temperature.

Output :

Current Temperature in Dhaka is 24.6°C

If you want to get specific city temperature, then pass the city name as a parameter of getWeather method:

var nodejsWeatherApp = require('nodejs-weather-app');

nodejsWeatherApp.getWeather('New York').then(val => {
	nodejsWeatherApp.printWeather(val);
});

Output :

Current Temperature in New York is 7.82°C

Basically, when the getWeather Promise will be resolved it will give a detailed weather object. So, you can easily modify it if necessary.

Like following:

var nodejsWeatherApp = require('nodejs-weather-app');

nodejsWeatherApp.getWeather().then(val => {
	printWeather(val);
});

function printWeather(weather) {
	let message = `Temperature in ${weather.name} is ${weather.main.temp}°C`;

	console.log(message);
}

If you want to see the full weather object, try this:

function printWeather(weather) {
	console.log(weather);
}

Output :
