The Angular Mini-Book The Angular Mini-Book is a guide to getting started with Angular. You'll learn how to develop a bare-bones application, test it, and deploy it. Then you'll move on to adding Bootstrap, Angular Material, continuous integration, and authentication.

Spring Boot is a popular framework for building REST APIs. You'll learn how to integrate Angular with Spring Boot and use security best practices like HTTPS and a content security policy.

The JHipster Mini-Book The JHipster Mini-Book is a guide to getting started with hip technologies today: Angular, Bootstrap, and Spring Boot. All of these frameworks are wrapped up in an easy-to-use project called JHipster.

This book shows you how to build an app with JHipster, and guides you through the plethora of tools, techniques and options you can use. Furthermore, it explains the UI and API building blocks so you understand the underpinnings of your great application.

Over 10 years ago, I wrote my first blog post. Since then, I've authored books, had kids, traveled the world, found Trish and blogged about it all.

RE: Life above the Service Tier

Yesterday I wrote the following:

I hope to develop with Flex, Grails, GWT or YUI + Struts 2 in the next 6 months. These seem like the most exciting technologies for Java web development in 2008.

This post is meant to explain why I think these are the most exciting technologies going forward.

A few weeks ago, a very interesting paper was posted on TSS: Life above the Service Tier. In this paper, Ganesh Prasad, Rajat Taneja and Vikrant Todankar introduce a new architectural style they're calling SOFEA, for Service-Oriented Front-End Architecture. To summarize:

The principles of SOFEA are:

0. Decouple the three orthogonal Presentation Tier processes of Application Download, Presentation Flow and Data Interchange. This is the foundational principle of SOFEA.

1. Explore various Application Download options to exploit usefully contrary trade-offs around client footprint, startup time, offline capability and a number of security-related parameters.

2. Presentation Flow must be driven by a client-side component and never by a server-side component.

3. Data Interchange between the Presentation Tier and the Service Tier must not become the weakest link in the end-to-end application chain of data integrity.

4. Model-View-Controller (MVC) is a good pattern to use to build the Presentation Tier.

Their paper can be downloaded from Life above the Service Tier.

I read this paper earlier this week and enjoyed reading it as well as thinking about the concepts it introduces. First of all, I believe SOFEA only applies to web applications and isn't a valid architecture pattern for web sites. While it may work for web sites, the traditional mechanisms (serving pages from the server side) seems to work well and isn't going away anytime soon.

So if SOFEA is the way of the future for developing web applications, where does that leave all the web frameworks that serve up pages server-side? This includes all Java web frameworks, Ruby on Rails and PHP. I think it leaves them in an interesting situation. They can still be usable if they can serve up the Application Download and the Data Interchange, but otherwise, they seem pretty much useless with this new architecture.

Is a SOFEA architecture a silver-bullet? I doubt it as there's still a lot of unanswered questions. How does SOFEA solve i18n and validation? Is it possible to re-use server-side validation rules in the client-side architecture? Granted this is probably a client-side framework feature rather than a SOFEA concept, but I still think it deserves some thought.

I don't know if i18n is that much of an issue for most applications. Most of the gigs I've consulted on in recent years were English-only, with no plans for internationalization. Validation is often server-side too. However, I believe server-side validation is often done simply because the web framework being used did not provide good client-side validation. How does i18n work in a JavaScript application? Can you bundle i18n scripts in the Application Download and have those read on the client-side - or do you serve up a different version of the application for different locales?

I think the most interesting part of SOFEA is how simple the backend becomes. With Spring and Hibernate (and some type of remoting) it should be easy to develop your SOA backend. But how do you publish those services? Do you still use a web framework on top to handle validation and such, or do you just markup POJOs with @WebService annotations?

Will 2008 be the year for SOFEA applications? It's definitely possible. I'm thinking of starting a Denver SOFEA user group to discuss and promote this architecture style. If I did - would you be interested in attending?

Google Code for Educators

Google Code for Educators looks like some really great stuff from Google.

This website provides teaching materials created especially for CS educators looking to enhance their courses with some of the most current computing technologies and paradigms. We know that between teaching, doing research and advising students, CS educators have little time to stay on top of the most recent trends. This website is meant to help you do just that.

In the Tutorials area, you will find a set of online tutorials to which you can point students to learn basic concepts in important new technologies, or if you need a refresher.

In the Sample Course Content area, you will find materials such as lecture slides, readings, problem sets and projects that you can download to use in your own course. All these materials are distributed under a Creative Commons license, so you are free to use and modify these materials according to the terms of the license. This area includes sample course content developed by CS Faculty from various universities and Google engineers.

In the Video Lectures area, you will find a set of video-taped lectures from Google Video on our technology areas. These videos are great opportunities for students and faculty to hear directly from some of the current pioneers in high-tech.

In the Tools section you will find a set of tools and resources to help you get started with the material highlighted on the site. This area includes tools developed by Google engineers, as well as links to external resources.
