Node.js API Client

For client side (browser, mobile apps …) .js library please see the .js library.

Example

Node.js
var recombee = require('recombee-api-client');
var rqs = recombee.requests;

var client = new recombee.ApiClient('--my-database-id--', '--db-private-token--', {region: 'us-west'});

// Prepare some userIDs and itemIDs
const NUM = 100;
var userIds = Array.apply(0, Array(NUM)).map((_, i) => {
  return `user-${i}`;
});

var itemIds = Array.apply(0, Array(NUM)).map((_, i) => {
  return `item-${i}`;
});


// Generate some random purchases of items by users
const PROBABILITY_PURCHASED = 0.1;
var purchases = [];
userIds.forEach((userId) => {
  var purchased = itemIds.filter(() => Math.random() < PROBABILITY_PURCHASED);
  purchased.forEach((itemId) => {

    purchases.push(new rqs.AddPurchase(userId, itemId, {'cascadeCreate': true}))

  });
});

// Send the data to Recombee, use Batch for faster processing of larger data
client.send(new rqs.Batch(purchases))
.then(() => {
  //Get 5 recommended items for user 'user-25'
  return client.send(new rqs.RecommendItemsToUser('user-25', 5));
})
.then((response) => {
  console.log("Recommended items for user-25: %j", response.recomms);

  // User scrolled down - get next 3 recommended items
  return client.send(new rqs.RecommendNextItems(response.recommId, 3));
})
.then((response) => {
  console.log("Next recommended items for user-25: %j", response.recomms);
})
.catch((error) => {
  console.error(error);
  // Use fallback
});
