Thanks to Ward De Backer for debugging assistance and functionality suggestions

In summary: QEWD is a Node.js-based platform for developing and running both interactive WebSocket-based applications and REST APIs. QEWD can run as either a monolithic back-end or as a set of MicroServices.

QEWD uses a unique architecture that prevents CPU-intensive or long-running APIs bringing a Node.js system to its knees, and includes QEWD-JSdb, a powerful high-performance, tightly-integrated multi-model database which, uniquely, presents your data as persistent JavaScript Objects.

The quickest way to try out QEWD is using the pre-built Docker version.

docker pull rtweed/qewd-server

There's also a Raspberry Pi version

docker pull rtweed/qewd-server-rpi

Create three files within a folder of your choice (eg ~/myQEWDApp), using the sub-folder structure shown below:

    ~/myQEWDApp
        |
        |_ configuration
        |            |
        |            |_ config.json
        |            |
        |            |_ routes.json
        |
        |_ apis
        |    |
        |    |_ helloworld
        |            |
        |            |_ index.js

  {
    "qewd_up": true
  }

  [
    {
      "uri": "/api/helloworld",
      "method": "GET",
      "handler": "helloworld"
    }
  ]

  module.exports = function(args, finished) {
    finished({
      hello: 'world'
    });
  };

Fire up the QEWD Docker instance:

docker run -it --name qewdup --rm -p 3000:8080 -v ~/myQEWDApp:/opt/qewd/mapped rtweed/qewd-server

or on a Raspberry Pi:

docker run -it --name qewdup --rm -p 3000:8080 -v ~/myQEWDApp:/opt/qewd/mapped rtweed/qewd-server-rpi

Try out your REST API:

http://{{host-ip-address}}:3000/api/helloworld

eg:

http://192.168.1.100:3000/api/helloworld

Information on QEWD-JSdb, the multi-model database that is integrated with QEWD. This is a unique, ground-breaking database abstraction which provides you with on-disk, persistent JavaScript Objects with which you directly interact via JavaScript.
