Creating a weather app using node.js and the OpenWeatherMap API

Hi people!!

Today I will teach you how to make this simple app using node.js and the OpenWeatherMap API.

1st step: Create an account on the OpenWeatherMap website.
In order to make things easier, you can create the account through this link: https://home.openweathermap.org/users/sign_up

2nd step: Select the “API Keys” option, then enter a Name in the “Name” field and, finally, click on the “Generate” button;

3rd step: Open the command line and enter the following commands:
- mkdir nodejs-weather
- npm init

The result will be something like this:

4th step: Create the index.js file on the command line and insert the following commands:
- touch index.js
- npm install request --save

The result will be according to this image:

5th step: Open the index.js file and insert the following code:

let request = require('request');
let apiKey = '34ef108283d61ecbca72455a49a8d6b2';
let cidade = 'Guarda';
let url = `http://api.openweathermap.org/data/2.5/weather?q=${cidade}&appid=${apiKey}&units=metric`
request(url, function (err, response, body) {
if(err){
console.log('error:', error);
} else {
let weather = JSON.parse(body);
let dados = `DADOS METEROLÓGICO PARA a ${weather.name}:
------------
- Temperatura (ºC): ${weather.main.feels_like}
- Humidade: ${weather.main.humidity}
- Visibilidade: ${weather.visibility}
- Vento (km/h): ${weather.wind.speed}`
console.log(dados);
}
});

6th step: Run the app using the command:

node index.js

And this is going to be the end result:

I hope you enjoyed!!
