Development

Understanding Visual Testing

Building new things and enabling products to deliver better experiences to users is the things that makes development compelling for me. This surprisingly leads me to think about testing a lot. Testing enables changes to happen sustainably. With tests I have confidence that the existing product works as expected and guarantees that this doesn’t change as new values are added. The more time I need to manually validate, the less time I have to do the work I enjoy.

The Redux Saga Black Box

I’ve recently been learning React and Redux Sagas for a new project I’m joining. It’s been fun transitioning from Angular and learning what project organization looks like without an opinionated framework. As I looked through the code I started to notice that yield is used a lot to generate values and pass those values to the Redux store using redux-saga. I haven’t worked with yield yet so I needed to do some research.

What my college degree gave me

I’m a software developer working at a company that regularly employs developers and technical leaders without a degree in computer science or engineering. Compared to previous jobs where everyone, including me, had a Computer Science degree, I find this is preferable. I collaborate with people having different perspectives, who possess a more varied array of skills from their backgrounds. Skills that come in handy when we need to think on our feet, solve a problem, do something most of us have never done before, or when we need to work through a client challenge.

Technical Leaders Enabling Stronger Teams

Technical leaders have a challenging job. We look to these leaders to make decisions, mentor developers, lead meetings, and tackle the most difficult problems on our projects. These leaders are often considered the “best” developers and are placed in leadership positions because of consistent performance in the face of challenge. However, while technical leaders have many roles and responsibilities, they also have an arguably more important responsibility to enable those they lead.

Finding Your Gateway to Learning Vue

This blog post was originally written for and posted on Rangle’s blog. You can find a link to the original here. Learning is a unique experience. It requires relating what we’ve previously experienced to new concepts and patterns. Those experiences are remembered specifically and each person remembers a concept a little differently. I remember a picture of a ball falling with labelled symbols, others might remember the equation, and some may remember the sounds of the physics hall.

Why Write Server Rendered Frontend Apps

This blog post was originally written for and posted on Rangle’s blog. You can find a link to the original here. Web applications have been evolving dramatically in recent years and many techniques have evolved to help our applications run faster, respond quickly, and load easily. With a wide array of modern development techniques it’s easy to overlook all of the options. Server-side Rendering web apps is one such option that has really impressive benefits when implemented in our applications.

Building an Event Source System - Part 2

Continuing my previous post, we’ll be working to setup an event source system using NodeJS. Event source systems utilize a common log of events to manipulate system state in a repeatable and scalable way. By recording state changes in logs, the system doesn’t need to rely on a database requests to gather state information. This has a variety of benefits that I’ve included previously. I enjoy working with the JavaScript/TypeScript, React, and NodeJS stack and find these tools very expressive.

Building an Event Source System - Part 1

I love working on the full stack of technologies involved with developing an application. It’s satisfying to design and implement a feature on the backend and request the data from the frontend application to render out something awesome. It’s very rewarding but it can be a long process to set everything up. It’s often a boilerplate experience and I often find myself doing a lot more devops than development.

Designing APIs that Enable Scaleable Frontends

This blog post was originally written for and posted on Rangle’s blog. You can find a link to the original here. Successful web development requires delivering strong communication between backend servers and frontend applications. The end client of an API needs to easily understand how to utilize the system to develop features and improve the application. REST (REpresentational State Transfer) has historically been used as the paradigm for this communication.

Why I Moved to Canada For Rangle

This blog post was originally written for and posted on Rangle’s blog. You can find a link to the original here. My name is Ben Hofferber and I am one of the recent hires at Rangle. Over the course of the last couple months, I ditched or sold all of my things and moved to Toronto from Boise, Idaho. Visiting and consequently moving to Canada were my first and second times outside of the United States.

What are Serverless Architectures?

Serverless Architectures are probably the coolest technology I’ve seen in the last few years. I think that these architectures will make huge strides in scalability, efficiency, and performance of applications. If you haven’t heard of serverless before, let’s first start with a definition: My definition: Building, customizing, and deploying services to production without maintaining servers. Industry definition: There are two different meanings: BaaS (Backend as a Service) and FaaS (Functions as a Service).

Using Babel in 2017

The JavaScript environment has been changing rapidly in recent years. As new frameworks and technologies draw more developers to JavaScript, those professionals find ways to improve the language. These rapid changes are difficult for browsers and standards to keep up with. This adaption time leads developers to implement language features that can compile back to the core language without having to wait for standards to catch up. The most widely supported version of JavaScript is the ECMAScript 5 (ES5) standard.

No Javascript on the Web

Being a web developer seems to be increasingly popular as we reach “critical web” where creating a website is a introductory activity for many. Entry Level Bootcamps mostly teach students to become web developers. The considerations when developing are vast and confusing for even experienced developers to traverse. One consideration involves the use of Javascript entirely. Or, should I say, it’s abandonment. No Javascript Web Many have adopted the concept that websites should render without enabling Javascript.

Logic Eludes Javascript Frameworks

I’ve recently been unfortunate enough to work on the impending migration away from AngularJS toward the new Angular. Eventually AngularJS will be officially deprecated by the Angular team once Angular 2+ overtakes its predecessor. When that happens, security vulnerabilities may keep AngularJS from being used in production apps. This means now is the time to get out! I’ve recently been learning Angular with TypeScript and just want to say I really hate every single build system I’ve seen thus far.

Effective Endpoint Design Techniques

I’ve recently come across some pretty effective concepts surrounding the design of endpoints. My career has been focused on backend server code recently where I’ve needed to create, extend, and refactor endpoints. I’d now like to share what I’ve discovered along the way that has made my endpoint code more maintainable, testable, and performant. I’ll be using a little bit of ES6 style NodeJS code with Express syntax to explain my points.

Simple Setup: DynamoDB with NodeJS

DynamoDB is a NoSQL Document Key-Value Database hosted by AWS. They offer to serve their database as a scalable cloud solution offloading the work of maintaining a database from developers. DynamoDB also features many integrations with other elements of the AWS stack like triggering Lambda functions and analyzing data in Elastic MapReduce. They support downloading and installing a local version of the database for development which allows developers to test without worrying about being charged.

Simple Setup: Sass with NPM

SASS is a tool built with Ruby that allows you to write CSS more simply with variable support and with an arguably nicer syntax. SASS stands for ‘Syntactically Awesome cSS’. The bare minimum SASS setup is actually to run it on Ruby and you can find out how on their website. Requirements Node and NPM. I’m using NPM(3.10.3) and Node(6.4.0) Setup Install node-sass npm install -g node-sass Create a SASS file to compile to CSS

TDD Chess

I was working on a learning project to create a chess game with Javascript and figured out a way to get stuff done in a fun way with TDD. Just wanted to throw together a post of what I’ve found. First off my Spellbook of choice for Unit Test Wizardry is Jasmine. I think it had pretty good syntax about a year ago so it’s what I seem to gravitate toward.

Javascript Object Creation

Object creation in Javascript is dead simple from a data type perspective: var obj = {a: 'Ben', b: 'Hofferber', c: 'Boise, ID'} typeof obj // object The datatype is straightforward and is really easy to implement. With JSON we can directly pass these objects into our javascript applications to be used immediately. I’ve even gone a bit further to look at the byte size of the object using a node library object-sizeof:

Simply Learning React

Learning React has always seemed daunting to me. I’ve downloaded several ‘quickstart’ projects in the past and quickly become overwhelmed. With the huge chain of dependencies I wasn’t able to get a clear picture of how it all worked. So I dropped it. I still used Ramda and other functional programming libraries, but I just passed React by because it wasn’t approachable. Then Redux’s author, Dan Abramov made a post titled “You Might Not Need Redux” in September.

Testing with Karma and Wallaby

I’ve recently been spending some time trying to improve my development techniques and one area I’ve been focusing on improving on is my testing practices. It isn’t obvious to new programmers as to why you might want to start testing your code. After all, if you can test out something that you’ve written that works shouldn’t it always work? Code can usually be assumed to be deterministic right? While that’s generally true with small programs, scripts, and school projects, it doesn’t hold up when it comes to larger programs and software.

Repeater Tracking in Angular 1.5

I’ve been switching a lot of my controllers into components thanks to the recent addition in Angular 1.5. The switch has been a great time to dust off some old code and really think about how my bindings are setup. I’ve switched to a lot of single binds in order to improve performance by reducing the number of watchers. However, when I went to throw everything into a repeater element, I started noticing some strangeness.
