How To: Generate Swagger REST API Client

Overview

As the web continues to grow and evolve, API’s are where all the magic happens that powers this innovation. REST API’s have become increasingly more favoured by developers for their ease of use over other alternatives (XML I’m looking at you).

Unfortunately, REST API’s can sometimes become a bit unwieldy in terms of documenting them, and consuming them. It is for this reason that Swagger was born! Swagger will autogenerate documentation for your REST API in the form of an Open API specification (swagger.json) document (formerly Swagger Specification). This makes it much easier for developers to understand and consume an API.

Third-party developers can then use the swagger.json specification file to either manually create an API client or auto-generate one for the preferred language of choice.

In this post, I’ll show you how to autogenerate a C# REST API client from a swagger.json in a few easy steps.

Solved: Why Async/Await does not work with .forEach

17th April 2022 / Shane Bartholomeusz / 1 Comment

The Problem

Javascript offers a number of different ways to iterate over an array. Recently while using the array.forEach syntax, I came across some interesting behaviour when using them with the async/await syntax.

To demonstrate. Lets take the following Javascript code which simply prints some messages to the console every 2 seconds.

function waitForTwoSecs(i) {
  return new Promise(resolve => {
    setTimeout(() => {
      console.log(`loop iteration ${i}`); 
      resolve('resolved');
    }, 2000);
  });
}

async function mainProgram() {
  const loopIterations = [1, 2, 3];
  console.log('mainProgram Start');

  loopIterations.forEach(async iteration =>  {
    const result = await waitForTwoSecs(iteration);
  });

  console.log('mainProgram finished'); 
}

mainProgram();

How To: Deep Clone a JavaScript Object

17th March 2022 / Shane Bartholomeusz / 0 Comments

Overview

JavaScript is becoming ever increasingly more popular as time goes by. While JavaScript has many advantages, it also has many interesting quirks or nuances that can catch out new beginners.

In this post I’ll show you how to deep clone a JavaScript object.

Problem

Okay … before we go any further … lets take a step back and understand the problem at hand.

Objects in JavaScript are passed by reference, meaning that any object returned by a function will point to the same memory reference as the original object. Therefore if the caller of the function modifies the returned object, they will actually be changing the original source object.

How To: Google Analytics In Chrome Extensions

Background

Google has replaced its legacy analytics library https://ssl.google-analytics.com/ga.js with the new and improved Universal Analytics library https://www.google-analytics.com/analytics.js.

I’ve been working on a Google Chrome Browser Extension but had some trouble integrating it with Google Analytics. Google’s own tutorial hadn’t yet been updated to use the new analytics library. In this post I’ll explain how I did it.

Progressive Web Apps: Future of the Web?

15th October 2016 / Shane Bartholomeusz / 0 Comments

Decisions, Decisions, Decisions …

In today’s rapidly evolving world of technology there has always been a clear distinction between mobile apps and websites. They each bring along their own set of pros and cons.

Although native mobile apps provide a first class user experience, they tend to have a higher barrier to entry; they require installation and are typically more difficult to develop/maintain. Websites on the other hand are platform agnostic and are typically easier to develop and maintain, however they provide a less engaging user experience.

In this article I’ll touch on a new technology called Progressive Web Apps which aims to bring these disparate worlds together. It may very well be the future of the web!
