A client implementation of Directed Edge's REST API in Node.js.
What is Directed Edge?
Directed Edge (http://directededge.com) helps you find related stuff.
It's a recommendations engine that plugs into your site to deliver Amazon-like recommendations. You can show your users personalized recommendations and similar content or products based on data you're already collecting.
Installation
Installing node-directededge
$ npm install node-directedge
Examples
Example 1
Get 5 new recommended interests for a user
var de = new DirectedEdge('username', 'password');
var params = {
excludeLinked: true,
maxResults: 5,
tags: 'interest'
}
de.getRecommended('user1', params, function(err, data, res) {
console.log(data);
});
// Outputs:
// {"@":{"version":"0.1"},"item":{"@":{"id":"user1"},"count":"5",
// "recommended":["interest2014","interest2098","interest1989","interest1932","interest1977"]}}
Example 2
Update an item
var de = new DirectedEdge('username', 'password');
// Params for puts are object literals with arrays, and
// in the case of weighted_links, nested arrays
var params = {
links: ['interest1', 'interest2'], // Creates links
weighted_links: [ ['interest3', 10], ['interest4', 0] ], // Creates links with weights
tags: ['user'] // Creates tags
}
de.putItem('user1', 'add', params, function(err, data, res) {
// Updates the item
});
Example 3
Remove from an item
var de = new DirectedEdge('username', 'password');
// We'll remove the links and tags created in Example 2
var params = {
links: ['interest1', 'interest2'], // Creates links
weighted_links: [ ['interest3', 10], ['interest4', 0] ], // Creates links with weights
tags: ['user'] // Creates tags
}
de.putItem('user1', 'remove', params, function(err, data, res) {
// Removes from the item
});
Example 4
Overwrite an item
var de = new DirectedEdge('username', 'password');
// We'll remove the links and tags created in Example 2
var params = {
links: ['interest5', 'interest6'] // Creates links
}
de.putItem('user1', 'overwrite', params, function(err, data, res) {
// Overwrites the item by passing in the overwrite method
});
Example 5
Delete a resource
var de = new DirectedEdge('username', 'password');
de.deleteItem('user1', function(err, data, res) {
// This deletes user1 from DE
});
