The first alpha of the official JavaScript driver arangojs‘ upcoming major release is now available on npm. Version 4 streamlines the driver’s API by removing unnecessary server roundtrips to obtain references to collections and graphs that already exist: Before: var db = require('arangojs')(); db.collection('users') .then(function(collection) { return collection.import(allTheUsers) }) .then(function() { return db.collection('blogs') }) .then(function(collection)…

AQB Update: Write More Readable Queries with ArangoDB

Alan Plum — Mon, 20 Apr 2015 07:37:24 +0000

The latest update to the AQL Query Builder for JavaScript addresses a major pain point: the “prefix notation” or LISP style syntax of AQL operator methods. Instead of calling the operator methods on the query builder object itself, you can now directly call them as methods on value objects. Let’s say you want to write…

With the ArangoDB Foxx Microservice Framework we’ve introduced an easy way to create a Web API right on top of the NoSQL database. In early January Max challenged Andreas (AngularJS / NodeJS) that they could build a full-stack application within half a day. The web application – in short – is a guessing game, in…

Crawling GitHub with Promises: ArangoDB Tutorial

Frank Celler — Tue, 06 Jan 2015 11:08:55 +0000

The new Javascript driver no longer imposes any promises implementation. It follows the standard callback pattern with a callback using err and res. I wanted to give the new driver a try. A github crawler seemed like a good side-project, especially because the node-github driver follows the same conventions as the Javascript driver. There are…

ArangoDB Query Builder: Simplifying Database Queries

The most powerful way to query your data in ArangoDB is by using ArangoDB’s own query language, AQL. In the past using AQL in your JavaScript code sadly would often require writing long, unwieldy strings. This made writing complex queries difficult and could often lead to subtle syntax errors or mistakes. The ArangoDB Query Builder…

Cheerio with Node.js and CoffeeScript | ArangoDB Tutorial

Frank Celler — Tue, 11 Feb 2014 13:40:07 +0000

Foxx’ main purpose is to create a beautiful API for your AngularJS, EmberJS or Backbone.js front-end. However, sometimes you want to do more. We, for example, needed to parse some HTML files. ArangoDB is capable of using some Node.js modules, but unfortunately Cheerio was not one of those. One problem was that we did not…
