Node Js Weather App

npm

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 :
