References to Design Pattern Libraries

When designing and developing software it's always useful to have a reference to common software design patterns handy. Apart from cloud design pattern libraries there are collections of more low-level or more general design patterns, too. These include the classic GoF design patterns and Martin Fowler's Patterns of Enterprise Application Architecture.

State of JavaScript Survey: 2018 Edition – Criticism from an Angular Perspective

Recently, the results of the 2018 edition of the State of JavaScript survey have been published. As usual, the report comes with handy categories such as front-end, data layer, testing or mobile. While I very much support the idea of creating a yearly survey of the JavaScript landscape and this survey in particular, which I have been supporting since its inception, there's a major issue with this year's edition: In contrast to its previous editions the survey results lump together (or at least the ...

Dinero.js: Working With Monetary Values in JavaScript

Working with monetary values can become a problem in any programming language and JavaScript certainly is no different in that respect. The naïve assumption that monetary values can be expressed as floating point numbers almost inevitably leads to rounding errors caused by precision and the fact that in most cases monetary values are represented as decimal numbers with just two (instead of an undefined number of) decimal places. Apart from that, money is not just a number but usually comprises a currency ...

Jenny Shen: UX Design Across Different Cultures

UX designer Jenny Shen recently has been featured on the Scott Hanselman's podcast with her work on UX design across different cultures. She's published a two-part summary of her experiences with cross-cultural design and internationalization (i18n) and localization (l10n) of websites and applications: UX Design Across Different Cultures — Part 1 UX Design Across Different Cultures — Part 2 These articles shed light on how distributing an application or publishing a website in another country not only requires translating the content and labels of UI elements but also has ...

Nonsense We Put up With: Complexity, Agile Gone Wrong and Enterprise Decision Making

Recently, I've come across a few articles that - although about ostensibly different subjects - share a common theme: When trying to create business value through software and devising the structures required to do so we all too often put up with wasteful processes, politics and toxic behaviour patterns that not only do not contribute to our goal but are downright detrimental. First, there's this transcript of a talk Martin Fowler gave at Agile Australia this year: The State of Agile Software ...

Dependency Management for Angular Unit Tests Using TestModuleMetadata

Since its inception it's always been one of the eminent design goals of Angular (and AngularJS before it) to make JavaScript applications easily testable and bake unit and E2E testing right into the development process. While the Angular team certainly has succeeded at this there's still the occasional snag you hit when writing unit or end-to-end tests. For the most part, the testing experience with Angular is terrific and testing JavaScript codebases has come a long way but of course there's always ...

Blogumentation

I'm not sure if he actually came up with the term 'blogumentation' but software quality engineer Jamie Tanna features quite prominently when searching for it so at the very least he appears to be one of its more avid and deliberate users. Anyway, while the term 'blogumentation' might be somewhat obscure the concept behind this particular portmanteau is a seminal one. Basically, it derives from the insight that often the best way to learn and internalise knowledge is to talk, write and ...

The 5 Levels of Logging Explained by Orhan Kavrakoğlu

In this article Orhan Kavrakoğlu explains the logging levels commonly used in software alongside with some pertinent examples as well as recommendations and best practices such as in which case to use which particular log level and how to present them to the target audience (i.e. other developers, system administrators or DevOps people) so they get noticed in accordance with their respective importance and urgency. As mentioned here before seemingly trivial improvements such as providing better context in your log messages can ...

Artur Śmiarowski’s Guidelines for Writing Readable Code

Code means communication has become a bit of a mantra for me. Source code isn't just the means by which you translate requirements into commands and structures a machine can understand. Source code also communicates your intent as a designer and engineer as to what a particular piece of software is supposed to do. If written in a clear and comprehensible manner code can serve as an authoritative design specification with no or little extra documentation needed. I would go as far as ...

Tool Suggestion – NGD: Angular Dependencies Graph

When working on a larger codebase knowing about the dependencies between components is crucial, particularly so when you're trying to understand how an existing application works. NGD - Angular Dependencies Graph (part of the Compodoc documentation suite for Angular) is a tool that - as the name suggests - generates dependency graphs (i.e. boxes and arrows) for Angular applications. Dependency graphs give you a high-level overview of an application's architecture and hence are a great first step in understanding how an application ...
