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 `git push heroku master` 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.

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!

January 29, 2019

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...

January 23, 2019
Iāve been researching using node as a back end for a few months now and SO MANY node articles, courses and project āstartersā 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!

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.
