Creating a Slack Bot

Brice McIver Articles, Conversational Apps, Development Technologies & Tools, JavaScript, Node.js Leave a Comment

If you have ever worked on a team project, then you’ve needed some way to communicate with your team. For a very small team with all of its members based in one place, face-to-face communication might be your go-to method of handling project conversations.

However, once your project size progresses past that point, there’s a good chance that you’ll at least evaluate using a collaborative software package to help manage your project.ย Slack is a popular option for this.

In this blog, I’ll show the basic steps you can take to integrate Slack with your existing tools and workflows.ย In particular, we will set up Slack for incoming webhooks and event subscriptions, showing how to program a Slack bot to say personalizedย “Welcome to the channel” and a “Goodbye” messages.

Let’s get started…

Angular State/Country Directive

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 weโ€™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.

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

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

Using Spring Integration In Conjunction With Spring Batch

Mark Fricke Articles, Development Technologies & Tools, JavaScript, Spring, Spring Batch, Spring Boot 6 Comments

Recently I was working on a development project for a client focused on Spring Batch. The program required a pull of the SFTP directory for an encrypted file, decryption of that file, starting of the Spring Batch program, and archive of that file.

Initially, my first thought was to use a shell script to perform all the tasks. Then one of my colleagues suggested Spring Integration; I thought this was great opportunity to learn and get my hands dirty with something new.

In this blog, I will show an example of Spring Integration configuration code, break it apart, and show how each part works.

Spring Integration turned out to be a simple solution to my clientโ€™s needs. Using Spring Integration and Spring Batch with Spring Boot, I was able to have a single deployable jar that included everything to run the application. I no longer needed separate deployments for the shell script, and batch process and all code is one Java project.
