A Lesson In ROI: Scratch vs. Adapt Existing Angular Code

On a recent client project, I needed to develop an Angular front-end for a form that included address information. As part of the address information, there were State and Country fields. I knew I needed to make these select lists, because from a UX perspective, it would be crazy to leave them as regular old text inputs. I knew I wanted to create directives to implement these select lists. I also knew I probably wasn’t the first developer to ever want to do this.

In this blog, I talk about a decision that all developers face every day: how to solve programming problems in the best way with the best use of time. The scenario we’ll talk about shows the use of Angular directives for creating select lists for country and state. In doing so, it provides a good understanding of Angular directives as one possible way they can help make Angular development great.

Event Storming For Rapid Domain Learning

John Hoestje Agile, Articles, Consulting, Project Management 1 Comment

Tl:dr: Use Event Storming to rapidly gain group understanding of complex business domains while having a more enjoyable time.

While I was browsing tech news sites looking for articles, a headline caught my eye talking about domain-driven design (DDD). Its main idea was to implement Event Storming to drive the understanding of the business domain. The more I read about it, the more I saw the value in what Event Storming offered.

On a recent consulting project, we were piloting Agile in a Waterfall environment, so in reality, any requirement gathering process used would have been new. We chose to compare Event Storming to User Story Mapping, allotting just one hour to work with each process. The process that the pilot Agile team favored would then be used going forward.

In this blog, I will share the main takeaways and benefits that became apparent while implementing Event Storming sessions, especially as compared to User Story Mapping. I will first explain the project we worked on and underlying opinions that drove our trial, what key aspects of Event Storming stood out to us, and then tips I picked up along the way for effective Event Storming sessions….

Converting Enterprise Applications to TypeScript

Clayton Terry Articles, Development Technologies & Tools, JavaScript, Single-Page Application, TypeScript Leave a Comment

We have all been there: some new technology comes out and we know it would improve our maintainability. But we can’t use it. We already picked a technology, it is already implemented, and we can’t change it now. We are stuck.

TypeScript does not work like that. TypeScript is JavaScript, and JavaScript is TypeScript. What this means is any existing files you have are compatible with any new file you add.

So why waste time changing if it’s all the same anyway? TypeScript has some great advantages that JavaScript does not. In this blog I will introduce some of those advantages, as well as some troubleshooting tips for if you run into issues when you choose to convert to TypeScript…

Building Applications Using the backbone.khs Framework Extension

John Boardman Articles, BackboneJS, Development Technologies & Tools, JavaScript, Node.js Leave a Comment

Backbone is a very powerful application development framework. However, it can be a little “close to the metal” in terms of how much work is needed to produce a working application with it. I see Backbone as a low level framework that could use some help in making it a bit easier and faster to use.

Keyhole has released an extension to help! The backbone.khs framework extension npm module (available by clicking the link) does its best to minimize the work necessary to get a Backbone application up and running.

The extension makes it easier to deal with:
• browser history
• root level non-Model Object implementation
• caching
• session support
• regions (which break pages up into more workable segments)
• a top-level Application object to manage the application
• modules to help with page and URL routing
• a Backbone View extension to seamlessly integrate Backbone Stickit and make Marionette templates easier
• a Collection View to enhance working with groups of items.

In this blog, I’ll describe these enhancements with some code examples…
