Nodejs weather app using Google Maps and Dark Sky API

Weather app

Command line application to get the weather by location, sending requests to Google Maps and Dark Sky API.

➜  weather-app git:(master) ✗ node app/app.js --a kantstr. 1
It's currently 45.61 in Kantstraße, Berlin, Germany. It feels like 38.65.

Callbacks, Promise wrappers, Promise based library...

This repository shows three different ways of requesting data from Dark Sky API. These are:

• Callbacks : app-callbacks/app.js : makes use of request library using its native callback support: request({ opts }, callback). Callback hell building up much ; ) : -> node app/app.js --a 'address here' .

• Promise wrappers : app-request-promise/app.js : uses the request HTTP request client, non-compatible Promise library. requests have been wrapped in custom Promise declarations to use promise chaining or async/await : -> node app-request-promise/app.js --a berlin .

• Calls via Promised based library : app-axios-promise/app.js : requires axios, a Promise based HTTP client for node. The simplest and quickest way of requesting async data : -> node app-axios-promise.js --address lalala
