Introducing Contact Cache It has been more than a year since I wanted to have some sort of “personal relationship manager”. In other words I needed a tool to write down notes about people since I am always forgetful. And since at that time I didn’t find anything satisfactory, I decided to build an app for myself that […]
Flask API Quickstart Application with JSON Web Tokens, SQLAlchemy and Pytest I created a sample Flask application that shows how to create HTTP API with authentication provided by JSON Web Tokens. It can be used to learn a bit about Flask, SQLAlchemy, JSON Web Tokens, Pytest and how it all works together. In particular, it shows how to: hash passwords using bcrypt issue and verify JWT […]
Rockets: Python-based launch page It has been 2 years already since I first played with Python and Flask and ended up creating Rockets.

How to reference hidden elements in Vue.js In Vue.js we can reference either Vue.js component or a standard DOM element by marking it with ref=”ourReferenceName” inside the HTML tag and later access this element easily inside the component with this.$refs.ourReferenceName. Let’s have a look at a simple component example: XHTML <template> <div> <div ref="referencedElement"></div> </div> </template> 12345 <template> <div> <div ref="referencedElement"></div> </div></template> JavaScript <script> export default { methods: { accessElement() { const element = this.$refs.referencedElement // TODO: do something with the element } } } </script> 12345678910 <script>export default { methods: { accessElement() { const element = this.$refs.referencedElement // TODO: do something with the element } }}</script> So far so good. The problem comes when we want to […]
Using validate.js instead of Vuelidate in Vue.js applications When I first needed some basic form of validation in my Vue.js application, I discovered and used Vuelidate, a popular validation library written specifically for Vue.js. Vuelidate is simple to use and works pretty well inside Vue.js components. It validates all different data sources in a component, based on the validation criteria provided as a […]

Why SCRUM doesn’t work? Let’s start by saying that companies hardly do SCRUM by the book. I will never forget a project manager, who, after he arrived to the office one day put a big “SCRUM” on our whiteboard and announced that from now on we will be doing SCRUM. You wouldn’t guess what we did afterwards. Every morning, […]
How to communicate with Angular components outside of Angular Recently I had to figure out the way to interact with Angular components from outside of Angular, from plain JavaScript rendered to a page. In my case I was opening a modal dialog written in Angular from a traditional server-side rendered page. I imagine I am not the only one who needs to mix Angular […]
