ArangoDB 2.4: EcmaScript 6, AQL Speedup and Hypermedia API Builder

04ReleasesTags:

This version is deprecated. Download the new version of ArangoDB

We are proud to announce the release of Version 2.4 of our multi-model database ArangoDB. It’s ready for download now and available for all major platforms.

This release is a major step forward. Use Foxx to create your favorite microservice with a few clicks, dockerize it and access it via a REST/Web API from everywhere. – Dr. Frank Celler (CTO)

You can now use EcmaScript 6 features like iterators, symbols, maps and sets by default and enable even more ES6 features with ArangoDB start options. The V8 engine upgrade in ArangoDB 2.4 also improves performance and speeds up V8 garbage collections.

The ArangoDB query language (AQL) gets more efficient group count calculation queries, an optional return value for AQL data-modification queries and improved index handling in filtering AQL queries.

Foxx 2.0: The new Foxx-Generator is a framework that enables developers to build Hypermedia APIs easily. Developers can create Web APIs based on a semantic description of entities and transitions using a statechart alike design approach. Additional to the recently added job queues and authentication services, Foxx got a new web-frontend to easily create new or install Foxx applications from Github or the ArangoDB Store.

Try the new tutorial Foxx in 10 Minutes to build your first Foxx application. Starting with a new Foxx app has never been easier.

Along with ArangoDB the new light-weight JavaScript driver arangojs 3.0 is ready to use.

Download the current 2.4 release and start building your own applications on top of ArangoDB!

Sending Mails from Foxx in the background via SendGrid

00FoxxTags:

ArangoDB Foxx allows defining job queues that let you perform slow or expensive actions asynchronously.

These queues can be used to send emails, call external APIs or perform other actions that you do not want to perform directly or want to retry on failure. Let’s say you want to send out an email every time you check off an item in your Foxx todo app and you want to use an external transactional email service to do that. More info

Crawling GITHUB with Promises

02API, Foxx, Javascript, nodejsTags: ,

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 a lot of promise libraries out there. The most popular one – according to NPM – was promises. It should be possible to use any implementation. Therefore I used this one.
