Node.js URL Shortener backed by Mongoose.js
No Callbacks, just Promises!
$ npm install short
Generates a Shortened URL Doc, then retrieves it for demo:
var shortURLPromise
, short = require('../lib/short');
// connect to mongodb
short.connect('mongodb:https://localhost/short');
short.connection.on('error', function(error) {
throw new Error(error);
});
// promise to generate a shortened URL.
var shortURLPromise = short.generate({
URL : 'https://nodejs.org/'
});
// gets back the short url document, and then retrieves it
shortURLPromise.then(function(mongodbDoc) {
console.log('>> created short URL:');
console.log(mongodbDoc);
console.log('>> retrieving short URL: %s', mongodbDoc.hash);
short.retrieve(mongodbDoc.hash).then(function(result) {
console.log('>> retrieve result:');
console.log(result);
process.exit(0);
}, function(error) {
if (error) {
throw new Error(error);
}
});
}, function(error) {
if (error) {
throw new Error(error);
}
});
Listing all Shortened URLs in DB:
var listURLsPromise
, short = require('../lib/short');
// connect to mongodb
short.connect('mongodb:https://localhost/short');
short.connection.on('error', function(error) {
throw new Error(error);
});
// promise to retrieve all shortened URLs
listURLsPromise = short.list();
// output all resulting shortened url db docs
listURLsPromise.then(function(URLsDocument) {
console.log('>> listing (%d) Shortened URLS:', URLsDocument.length);
console.log(URLsDocument);
process.exit(0);
}, function(error) {
if (error) {
throw new Error(error);
}
});
