APOD and Near-Earth Asteroid Information - NASA API

This repository utilizes NASA's API to fetch two sets of data:

1. Astronomy Picture of the Day (APOD)
2. Near-Earth Asteroid Information (NeoWs)

Installation

To use the APOD and Near-Earth Asteroid functionalities, install the aerolib package from npm:

npm i aerolib

Link to aerolib package on npm

Example Usage

1. Astronomy Picture of the Day (APOD) The APOD function retrieves data related to NASA's Astronomy Picture of the Day, including the image, explanation, and other metadata.

   Using async/await

   const aerolib = require('aerolib');
   
   async function getAPOD() {
       const data = await aerolib.getAPODdata();
       console.log(data.copyright);
       console.log(data.date);
       console.log(data.explanation);
   }
   
   getAPOD();

   Using Promises

   aerolib.getAPODdata().then((data) => {
       console.log(data.copyright);
       console.log(data.date);
       console.log(data.explanation);
   });

   Available Data:

   • copyright: Copyright signature for the image.
   • date: Date of the photography.
   • explanation: A brief explanation of the picture.
   • hdurl: The URL for the HD version of the image.
   • media_type: Type of media (image, video, etc.).
   • service_version: Version of the service.
   • title: Title of the image.
   • url: URL for the image.

2. Near-Earth Asteroid Information (NeoWs) The Near-Earth Object Web Service (NeoWs) allows you to fetch data on asteroids that are near Earth.

   Fetch Asteroid Count for a Date Range

   aerolib.NeoWselementcount("2015-09-07", "2015-09-08")
       .then((count) => {
           console.log(count);
       });

   Fetch Near-Earth Objects for a Date Range

        aerolib.near_earth_objects("2015-09-07", "2015-09-08").then((data) => {
            data.forEach((d) => {
                console.log(d.links)
                console.log(d.id)
                console.log(d.neo_reference_id)
                console.log(d.name)
                console.log(d.nasa_jpl_url)
            })
        })
