This lecture summarises the background to React.js and outlines its 4 underlying core concepts
In this lecture we'll get a simple "Hello World" application up and running. We'll examine all the pieces needed to get started developing with React.js
In this lecture we'll see how to define a React.js component.
In this lecture, we'll begin to create a simple hierarchy of components
In this lecture, we'll examine how props are used to control the behaviour of components
In this lecture, we'll extend the application by invoking a function in the parent component via a button click handler in a child component.
In this lecture, we'll complete our simple application by introducing and applying a state variable.
In this lecture, we'll examine the techniques and options available for breaking down our application into separate standalone modules.
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.
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:
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.
