What are Progressive Web Apps and how to start?

Picture a company that has a nice web application, but also has plans to create a Native Application for mobile devices. Unfortunately creating a complete Native app, will cost a lot of time and money to develop. If this is your situation, maybe transforming your web application into a Progressive Web App can help you.

The term “Progressive Web App” isn’t a formal or official name. It’s just a shorthand used initially by Google for the concept of creating a flexible, adaptable app using only web technologies.

The goal of Progressive Web Apps is to make the end-user feel as if they are working in a Native App, as we know it from mobile devices (Android and Ios).

Another big advantage of a Progressive Web App is the fact that any existing web application can easily become a Progressive Web App.

Migrating AngularJs to Angular – part 1

In my previous article, I explained that every company has to think about what they want to do with the old AngularJs application? For some companies, it’s better to completely rewrite the application. Maybe even not in Angular anymore? (if you have the resources for it) And for some companies, it’s better to create a hybrid situation/application in which you can let the AngularJs application, with new Angular components, co-exist. This can really help you to easily make the transition from AngularJs to Angular. 

This blog post is the first part of a series of blogs that will help you to take a look at a hybrid AngularJs/Angular application. Let’s start by setting up an environment for our migration.

The end is near for AngularJs

In 2010 Google introduced AngularJs. Originally it is developed in 2009 by Miško Hevery en Adam Abrons. AngularJs is a Model View Controller (MVC) javascript framework. It has been / or still is used by many companies for creating SPA (Single Page Applications). Few years later AngularJs became part of the MEAN Stack. MEAN stands for MongoDB, Express.js, AngularJS, and Node.js. MEAN is an end-to-end JavaScript stack used for cloud-ready applications.

AngularJs became very popular because of a set of features that really helped programmers constructing stable, scalable and robust web-applications. AngularJs reached the top segment of the market and was compared to ReactJs and EmberJs also a good choice to build your product with.  

But all good things, come to an end.

SPA (Angular, Vue, React) security issue, switch to PKCE code flow

These past few weeks I have worked on the implementation of OpenID within a Hybrid AngularJs / Angular application. For this implementation, I used the Angular OpenID client from Manfred Steyer. This client is OpenID certified and makes it easy to connect your Identity Provider (IdP). It supports implicit flow and PKCE code flow. There is also good documentation and examples so I am not gonna show you the code because it’s pretty clear in the documentation.
But what I do want to tell, is that by using implicit flow you are vulnerable to a couple of security issues.
