Adding a junit formatter to jest test results for a node app on Azure Pipelines

October 20, 2019

If you’re publishing a node app on Azure pipelines you will want to publish the output of your tests. The publish tests task on Azure has limited format support so you have to convert the test results to XML for processing.

How to configure a pipeline on Azure Devops to build and deploy serverless graphql and react client

October 19, 2019

I need to automate deploys on Azure Devops for a project I’m working on. I want it to work as cheaply as possible so serverless or PaaS was desirable. Read on to see the azure-pipelines.yaml file I used to make this work.

Returning null from a GraphQL mutation in type-graphql

August 06, 2019

Null is not a GraphQL type so to return null from a GraphQL mutation you have to return a GraphQL type that is nullable. All GraphQL types are nullable by default so you can just return a bool in the schema but return void from the implementation. It shouldn’t be too common to have a null response though, even for a mutation it could be better to return a state of the created item.

Typescript error "does not satisfy the constraint new" when using InstanceType in typegoose

August 06, 2019

If you get an error when trying to use InstanceType from typegoose as a parameter to a method in typescript make sure you are importing it from typegoose explicitly. There is a thing called InstanceType defined in JavaScript already. Typescript will use this by default and that’s where the error is coming from.

How to find distinct items in an array in javascript or typescript

August 05, 2019

I have to sort a bunch of work items in to organisational areas so I needed to know what were the distinct categories of objects in an array. In C#/Linq there is a nice IEnumerable.Distinct(f(x)) method available but JavaScript doesn’t have something like this yet. I didn’t want to install a helper like lodash if I could avoid it. Luckily my list was simple strings so I was able to use ‘Set()‘.

How to await async functions in specific sequence using typescript

August 04, 2019

I was posting messages to a slack webhook recently and I wanted to post a list of messages in the correct order. I had to await each one before calling the next. I tried a few different methods but only one worked the way I expected it to.

How to log full objects in winston (hint... Use meta data)

July 30, 2019

I’m exploring the Azure Devops API at the moment and I find logging out the API responses is far better than trying to understand the documentation. It seems super obvious now but it took me some messing around to figure out that you need to supply the object as meta data to the winston logger!

How to check bitwise mask in typescript

July 29, 2019

I’m currently building a little app that talks to the Azure Devops API and I had to check a bitwise operator in typescript today. I hardly ever do this these days so it took me a bit of time to get it right!

A gitignore file for Katalon projects

June 23, 2019

You need to add a gitignore file to your katalon directory or you will have lots of compiled files in your repository and it will be harder to compare changes in diffs when reviewing pull requests. Here is a suitable git ignore file for Katalon projects.

How to force a rebuild on Heroku without pushing using heroku-release-retry plugin

March 02, 2019

I had a deploy on Heroku fail because of a database issue. The code deployed but a dependancy meant that the application couldn’t start. If you try to run you just get “Everything is up-to-date”. My code didn’t need to change but I wanted the “deploy” to be re run WITHOUT pushing a new commit.

A retrospective on mentoring four new developers

February 12, 2019

Late last year I had the pleasure of helping a team of students build a prototype for a non-profit here in Auckland. The non-profit needed a prototype to raise more funds and get feedback on their plan. I’ve helped run teams and mentor junior developers in large organisations. It’s much easier because the support, tools, frameworks, systems of the organisation are already available. For this project the student teams had a blank slate and had to decide on everything from how they would communicate with the sponsors to how they would host the software. I wanted to write down what I learned and note some of the mistakes I made so that I have a framework for the next time I help new developers!

When Mocha doesn't run tests in subfolders on either windows or your CI server

January 29, 2019

I use a Windows PC for development and I had a problem where some of my mocha tests were not running on my CI server. The issue was that I use GitLab’s CI system which uses a Linux docker image to run the tests so the difference was the OS. This would also affect teams with developers on both Windows machines and Macs. Here’s how I fixed it…

Adding static JavaScript files to a react typescript project

January 25, 2019

I had to import a JavaScript in to my React project with typescript and typescript gave me an error. It wasn’t causing my build to fail but it was annoying seeing it in the console. Here’s how I got rid of the error.

Be careful of the JWT hype train

January 23, 2019

I’ve been researching using node as a back end for a few months now and SO MANY node articles, courses and project “starters” on GitHub suggest using JWT on your client facing API as a session token. I think there’s way too much hype around it and people are using JWT because it’s shiny!

How to add cors protection to an express application

January 17, 2019

Cors protection is a recommended security configuration for any api. It protects your customers from unexpected attacks by blocking websites you haven’t approved. If you have a devOps team they will handle this for you. But if you are a single maker with an application on Heroku and front end on Netlify you need to implement this yourself.

The Customer Workshop

November 21, 2017

I lead a team of developers that work on one of the busiest New Zealand websites. We have ~4 million members and ~850,000 unique users every day. Working at this kind of scale means the real people who buy and use our products can get lost behind user personas or Jira ticket numbers.

When agile gets dangerous

September 14, 2017

If you’re selling your teams on some form of agile but the reality they work in is completely different, you are damaging and demotivating your teams through confusion and an impossible to achieve vision. If you’ve adopted ‘agile’ do yourself a favor and check the health of the adoption right now.

Giving your first machine learning workshop

June 20, 2017

Last week I offered to give a workshop on machine learning to share some of what I’ve learned so far. I had 2 goals for my workshop – first, I wanted to show everyone that they shouldn’t be afraid of machine learning. Second, I wanted to get people set up with anaconda so they can continue to learn themselves.

Smart Bear Ready API

February 02, 2017

I recently had a problem where our test analysts use Ready API software from Smart bear but our API authentication does a custom hashing function on the content. For tests to work we had to hash the entire request and apply headers for each test step. There is an events hook in Ready API where you can add Java code to be run for event triggers. Unwrapping the content in the available request context API was difficult to figure out. First open the Events dialog. Add a new event for RequestFilter.filterRequest to do something for every test step with a request. https://gist.github.com/darraghoriordan/3915a246198dfe72e39f90f72566cc5e#file-header-groovy

Swagger UI: Custom HMAC hash authentication headers

January 11, 2017

Last year I launched a new API for an integration project. It’s using Microsoft’s WebApi framework. I was looking for a fast way to document the API so I wouldn’t have to do much work and clients could use the API easily. After some research it was obvious that I needed Swagger.
