GraphQL is a query language created by Facebook for modern web and mobile applications as an alternative to REST APIs. Following the original announcement alongside Relay, Facebook has published an official specification and reference implementation in JavaScript. Recently projects outside Facebook like Meteor have also begun to embrace GraphQL.Users have been asking us how they can try out GraphQL with ArangoDB. While working on the 2.8 release of our NoSQL database we experimented with GraphQL and published an ArangoDB-compatible wrapper for GraphQL.js. With the general availability of..

The implementation of the JavaScript require function will be adjusted to improve compatibility with npm modules. The current implementation in 2.7 and earlier versions of ArangoDB strictly adheres to the CommonJS module standard, which deviates from the behaviour implemented in Node and browser bundlers.

Module paths will now be resolved in the following ways:

• relative paths (e.g. ./hello) will be resolved relative to the current file
• absolute paths (e.g. /hello) will be resolved relative to the file system root
• global names (e.g. hello) will be resolved by looking in the following places:

Long awaited and now we´ve finished it! New major release of ArangoDB 2.7 is ready for download. First of all a big thanks to our community for your great support! We´ve implemented a lot of your ideas! After your feedback to RC1 and RC2 we are happy to bring a new major release to the world. With ArangoDB 2.7 we increased our performance even further and improved query handling a lot.

What big improvements are in for you?

In this article I want to explain how to setup a nonce-microservice using docker.

Nonce are one-time tokens that are used to ensure that an action can only be taken once. In a project, we needed to ensure that a pay button is only pressed once. Note that nonces are not used to sign requests or identify a user. This is a separate mechanism.

ArangoDB contains a nonce implementation which is a variation of Bloom-filters. It allows to store nearly unlimited nonces within a limited amount of memory. Nonce are allowed to age, that is after an hour they might expire. If there is sufficient interest,..

The generated API documentation in ArangoDB 2.6 has been updated to Swagger 2. To see the API documentation for any of your Foxx apps, open the web admin frontend and select your app from the Applications tab. For information on how to describe your own APIs in the generated documentation, see the ArangoDB documentation.

Previously on the ArangoDB blog we saw how we can use the configuration field in manifest.json to make Foxx apps configurable and more re-usable. This is all well and good if we just want to pass in simple values to a Foxx app but sometimes you want to pass in entire Foxx apps. This is where dependencies come in to save the day.

Let’s say you want to use the session storage provided by the ArangoDB sessions app available on the Foxx app store using Foxx exports and imports. Because you hadn’t yet heard of configurations, you simply hard-coded the mount path of your copy of the sessions app in..

While the optional configuration field in Foxx manifests had experimental support all the way back to ArangoDB 2.1, the feature was previously undocumented and not well understood. The upcoming ArangoDB 2.6 release officially introduces Foxx configurations, allowing you to make your existing Foxx apps more re-usable and to make better use of third-party apps.

Let’s say your Foxx app needs an API key to make a request to a third-party service using the request module introduced in ArangoDB 2.5. Without using configurations, your code might contain the hard-coded API key:

Some of the most frequent questions by new programmers learning Foxx have been about testing. While the HTTP API can easily be tested with any HTTP client and any JavaScript code that can be isolated from the ArangoDB APIs could be tested in similar environments like Node.js or io.js, it was all but impossible to test Foxx apps inside ArangoDB.

The upcoming release of ArangoDB sets out to change this. As of version 2.6, ArangoDB Foxx will come with full support for Mocha tests allowing you to use the same test framework for your frontend code in the browser, your server-side code running on..

Aside from the more noticeable features, ArangoDB 2.5 also added the console object to the scope of all Foxx app modules. Unlike the object already available by importing the console module, the Foxx console logs all messages directly to the database.

Great to know your database scales and database vendors like ArangoDB add some statistics on node / cluster health directly in their products.

But running a bunch of different servers and applications you need a central hub to collect monitoring data from all services running. In a series of recipes Willi shows how you could easily add monitoring capabilities to NoSQL databases like ArangoDB using collectd with the cURL JSON plugin.
