Setting Up Angular 2 MockBackend

Todd Leininger AngularJS, JavaScript, Technology Snapshot, Tutorial 2 Comments

Todd was working on a client project developing one of the company’s first Angular 2 applications when he found that he needed access to the REST services before they were ready. He needed a good way to mock them up, so he set up a mock service for an Angular 2 application using MockBackend.

In this article Todd shows a step-by-step example of setting up a mock of RESTful web service APIs for an Angular 2 application using Angular’s MockBackend. With this method, he could then use that mock to work on the application before the real APIs were ready.



Using RetroPie to Build Keyhole’s Gaming Console

Brad Mongar Keyhole, Technology Snapshot 2 Comments

You know you work at a great company when you say to your boss that there is a Linux build for the RaspberryPi that is dedicated to playing old arcade and console games…. and he agrees to buy one for the company office for the low, low price of a written blog post about it.

Keyhole Software is just such a company and this is the promised blog post. Specifically, I’ll be talking about the process I used for setting up the Raspberry Pi. I’m hoping that it will give you a guide (alongside the official documentation) for making your own gaming console!



Using Toastr With SignalR

John Holland .NET, Technology Snapshot, Tutorial Leave a Comment

When you submit data to the server within a Single-Page Application (SPA), you are not performing the usual form post of data that would generate a new page load. Rather, you send the data using AJAX and are able to parse the response returned by the API using JavaScript and can act accordingly. In the past, this would most likely come in the form of an alert or populating a div with the appropriate message. This approach did what I needed it to do, essentially notifying the user of success or failure and allowing them to move on with their work.

Enter Toastr. Now I can have a non-blocking, consistent way in which to display these messages to the user, that are styled respective to the type of message it is. This is where the story gets interesting. So with this easy to use, non-blocking, consistent way of displaying messages, you can pair it up with SignalR and provide that same messaging from the server-side.

In this blog, we will demonstrate the use of the Toastr messaging library and how, when you couple it with SignalR, it can provide you with an easy-to-use, consistent messaging alternative.

Creating a SQL Database Project for Isolated Development

Rusty Divine .NET, Databases, Problem Solving, Technology Snapshot, Tutorial Leave a Comment

In this article you see how to create a database project that will let you quickly and consistently deploy a database to your local environment. This approach can help to solve some issues from team members interfering with each other’s work on a shared development database.

Then, in an upcoming article, we will show you how to take the next step to include this database project in your continuous integration process and deploy it to each environment up the chain to production so that you can eliminate the need for any direct interaction with database updates.



Quick Start: End-to-End Testing With Protractor

Todd Horn AngularJS, JavaScript, Technology Snapshot, Testing, Tutorial Leave a Comment

As AngularJS applications become more complex, manual testing becomes unreliable and repetitive. Unit Testing is a great start for testing the code, but eventually End-to-End testing is needed for better coverage.

A great tool to use for this is Protractor, an end-to-end test framework for AngularJS applications. In this blog, we’ll briefly introduce the benefits of Protractor and give you the steps needed to get started with the tool.



Keyhole Labs Releases Spring Boot Starter For Trouble Maker

Lauren Fournier Company News, Java, Spring, Trouble Maker Leave a Comment

The Keyhole Labs team is excited to announce the release of a Spring Boot starter for auto-configuration of Trouble Maker.

This new auto-configuration allows Spring Boot applications to easily enable Trouble Maker. Trouble Maker randomly takes down services during normal business hours in an effort to test stability and automated recovery. It also provides an ad hoc console to test application durability on demand.

Handlebars – A More Dynamic Way

Dagin Fullmer JavaScript, Single-Page Application, Technology Snapshot, Tutorial Leave a Comment

Handlebars.js is a popular templating engine based on the Mustache template language. In this blog, we will explore how Handlebars is a dynamic template creation tool and what benefits logic-less templates afford us. During our discussion we will cover Handlebars’ precompiling, partials, and helpers, and how each supports or contradicts dynamic and logic-less templates…



An Introduction To Underscore.js

Nick Brown BackboneJS, JavaScript, Technology Snapshot Leave a Comment

Underscore is a JavaScript utility library with many useful functions to handle common programming use cases. In this blog, I discuss some of the more useful functions I have found inside of Underscore. Some of the benefits are less apparent in smaller and simpler code chunks. But, as the complexity of the code increases, this is where Underscore really shines as the useful toolbox that it is…



Getting Started With JHipster, Part 3

Matt McCandless AngularJS, Java, JavaScript, Spring, Tutorial 1 Comment

Welcome back to this JHipster tutorial series! In part one we covered creating a monolithic application. In part two, we walked through creating a microservice application (which was a bit more complicated).

For those of you out there working to get things going with JHipster, there are some setup things and “gotchas” that I’d like to highlight. So this little blog is more of a helper for those of you who have decided to try JHipster out and play around with it. That’s what we’ll be discussing in this blog post with the hope that I can help you minimize the getting-up-to-speed curve…
