#qryq

I have given talks on qryq a few times now, and, quite often I have been asked, about how to actually begin using qryq.

qryq is a general purpose library, and it can be used in a number of different ways. The most common, or default, use for it is to expose a single API endpoint on a server, where any number of APIs can be invoked in a query queue specified by the client. Thus I have created a template server that does just this, and have (creatively) decided to name it qryq-server.

This project is most useful as a scaffold or template, where you simply make a copy of it, and in most cases merely need to add more methods to the api object.

Check out qryq-server on github

A comparison of async to qryq when specifying a compound query that is diamond-shaped.

Why diamond shaped? The diamond dependency problem is a not-so-simple problem to solve, and so I have chosen this as a litmus test for testing and demonstrating compound queries. Call it a SSCCE.

Some important changes to qryq since its first announcement:

Picked GPL v3 as the licence

Fully extracted as its own project

Inline referencing + property drilldown of the results of other qrys

Specifying depends for each qry is now optional, and will be inferred when not present

Unit tested using nodeunit

Qryq has also just been published as a node module. You can now get it using:

npm install qryq
