Published 7/2015 English

Course Description

This course is designed for people who are interested in getting the EWDjs development and run-time platform up and running on a Linux System. The course will focus on the Ubuntu 14.04 Server flavour of Linux, running as either a Virtual Machine or an Amazon Web Services EC2 instance.

In the case of the Ubuntu Virtual Machine, I'll demonstrate how things are done using VMWare, but the steps and approach will be applicable to other hypervisors such as VirtualBox

For the Linux user and EWDjs newbie, this course is an ideal pre-cursor to my other beginner's course: "Getting Started with EWDjs". Whilst the latter course focuses on developing using a Windows platform, there's really no difference in development approach apart from file path syntax.

What are the requirements?

  • Students should know how to use VMWare or an equivalent Virtual Machine environment; and/or
  • Students should have an Amazon Web Services account and know how to start up an Amazon EC2 instance
  • Students should be familiar with the Linux Operating System

What am I going to get from this course?

  • install all the components needed to run EWD.js on Linux Systems
  • get EWD.js up and running on a Ubuntu Linux Virtual Machine
  • get EWD.js up and running on a Linux-based Amazon EC2 instance
  • install EWD.js with the VistA EHR, using existing installers

What is the target audience?

  • This course is aimed at anyone wishing to get EWD.js up and running on Linux platforms
  • It is not suitable for WIndows users, or anyone wanting to learn how to develop applications with EWD.js

Section 1: Introduction
Running EWD.js on Linux Platforms
Preview
04:09
Section 2: Pre-installation Steps
04:12

This lecture will show you how to install the free VMWare Player on a Windows machine.

There are many other choices of hypervisor for you to use, so don't feel you'e limited to VMWare Player: it's just a convenient and free option for the Windows user, and I've found it to be a good, easy to use and reliable choice.

02:30

This lecture will show you how to install puTTY on a Windows Machine. puTTY gives you terminal / command-line access to a Linux machine over an SSH connection

02:56

This lecture will show you how to install the free, Open Source WinSCP application on a Windows machine. WinSCP is a great tool that provides file manager access to a Linux machine over an SSH connection. It also allows you to create and edit files on the Linux machine via an editor (Notepad by default) on your Windows machine.

03:14

This lecture reviews the tools and applications that I've found to be useful when using Linux Virtual Machines and Amazon EC2 Linux instances from within OS X

15:09

In this lecture I'll show you how to create a Ubuntu 14.04 Server Virtual Machine (VM) that you can use with VMWare Player or whatever other virtualisation application you choose to use. The installation will be optimised for use as Virtual Machine.

12:03

In this lecture you'll learn how to access your newly-created Ubuntu Linux VM by using puTTY and WinSCP on a Windows machine.

10:41

In this lecture I'll show you how to create an Amazon Web Services EC2 instance, running Ubuntu 14.04 Server

07:20

In this lecture you'll learn how to access an Amazon EC2 instance running Ubuntu Linux from puTTY and WinSCP on a Windows machine

Section 3: Installing EWD.js on Linux Platforms
07:01

This lecture takes a quick look at the pre-built installers that are available for creating Linux-based EWDjs systems

08:17

In this lecture I'll show you how to run our installation script that automatically installs the GlobalsDB database and EWDjs, configures it and sets it all up ready for you to run.

06:56

In this lecture I'll show you how to run our installation script that automatically installs the GT.M database and EWDjs, configures it and sets it all up ready for you to run.

12:18

In this lecture I'll show you how to run or adapt our installation script that installs Cache and EWDjs and configures it ready for use.

This lecture will show you how to upgrade the dEWDrop Virtual Machine so that it can run EWDjs

03:52

This lecture will show you how to run EWDjs as a service on the dEWDrop Virtual Machine

13:20

This lecture will show you how to use the OSEHRA installer, to create an EWDjs-enabled VistA system

Section 6: Building and Running EWD.js Applications on Linux
09:33

This lecture provides a quick guided tour of the EWDjs environment that is installed on a Linux platform.

Instructor Biography

Rob Tweed, Author of EWD.js

My name is Rob Tweed. I'm a Director and co-founder of M/Gateway Developments Ltd, a UK company that, since 1996, has specialised in web and internet technologies, in particular in conjunction with the Caché and GT.M databases.

I'm the author of EWDjs, a Node.js-based framework for browser-based client/server applications. EWDjs is specifically designed for use with the Caché and GT.M technologies, but supports other NoSQL databases including MongoDB and can be used as a framework with any other database technology.

My IT career started at the Royal Marsden Hospital, the UK's premier cancer hospital based in London and Surrey, where I headed up the application development team within their Computer Department.

I spent 4 years working in the Healthcare IT team at Touche Ross Management Consultants in London, during which time (and for several years after) I was a key member of the NHS-Wide Networking Project team, one of Europe's largest-ever networking projects, managed by the NHS Management Executive.

After becoming an independent consultant in the mid-1990s, I have focused exclusively on web technologies, with a particular focus on their role in healthcare. I was the inspiration behindWebLink, a web gateway product that I and my fellow co-director Chris Munt created and sold toInterSystems, the vendor of Caché. I also developed InterSystems' WebLink Developer framework, the pre-cursor to EWDjs, and have consulted with and supported many of InterSystems' major customers around the world to help them build their web application projects. The largest of these customers is Quest Diagnostics in the USA who use both WebLink Developer and EWD (the immediate predecessor to EWDjs) to support their Care360 application: the world's largest Caché-based, internet-facing web application. I provide support to Quest Diagnostics for both EWD and WebLink Developer.

Recent high-profile work includes my technical support and development of the JavaScript User Interface for Oroville Hospital's winning entry in 2013 to the US Dept of Veteran's Affairs Scheduling competition.

My technical expertise includes over 30 years' experience in the Mumps, Caché and GT.M technologies in not only healthcare but also a wide range of market sectors including financial services, online publishing and retail. Other experience includes:

  • Nodejs
  • Javascript
  • JSON
  • Javascript frameworks including Bootstrap, jQuery, ExtJS and Sencha Touch
  • NoSQL databases
  • WebSockets
  • XML
  • Mobile web applications and frameworks

I have presented at a wide range of conferences in the USA, UK and elsewhere, including Ajax World, Cloud Computing, EHI Live, London Node.js Users Group and InterSystems' Developers Conference.
