http://open-notify.org/ takes raw data from NASA and turns it into APIs related to space and spacecraft.
// Dependencies
var Promise = require('bluebird');
var moment = require('moment');
var request = Promise.promisifyAll(require('request'));
var geocode = require('notebook')('capicue/geocode/4.0.1');
// API endpoints
var issNowUrl = 'http://api.open-notify.org/iss-now.json';
var issPassUrl = 'http://api.open-notify.org/iss-pass.json';
var astrosUrl = 'http://api.open-notify.org/astros.json'; 0;
Get the current position of the ISS.
function currentPosition() {
return request.getAsync(issNowUrl).then(function(body) {
return JSON.parse(body[1]).iss_position;
});
}; 0;
Find out when the ISS will next be above you.
function nextPass(location) {
return geocode.simpleLookup(location).then(function(coordinates) {
var options = {lat: coordinates.lat, lon: coordinates.lng};
return request.getAsync({url: issPassUrl, qs: options});
}).then(function(passResult) {
var timestamp = JSON.parse(passResult[1]).response[0].risetime;
return moment.unix(timestamp).fromNow();
});
}; 0;
Find out how many people are currently in space.
function numberInSpace() {
return request.getAsync(astrosUrl).then(function(response) {
return JSON.parse(response[1]).number;
});
}; 0;
Then find out who they are.
function peopleInSpace() {
return request.getAsync(astrosUrl).then(function(response) {
return JSON.parse(response[1]).people;
});
}; 0;
module.exports = {
currentPosition: currentPosition,
nextPass: nextPass,
numberInSpace: numberInSpace,
peopleInSpace: peopleInSpace
}; 0;
await currentPosition();
// Change this to use your location in this example
var myLocation = "San Francisco, CA";
await nextPass(myLocation);
await numberInSpace();
var people = await peopleInSpace();
people.map(function(person) {
return person.name + " (" + person.craft + ")";
});
