Progressive Web Apps

When you visit a website, web-apps are mainly what you will use. Believe it or not, we utilize web apps almost everyday. From online wikis to video hosting websites, these are all including in the wide world of Web-Apps. Today, I want to discuss Google’s developer program and their developer tools for progressive web apps. But what are progressive web apps? Progressive web-apps are applications that are reliable, fast, and engaging, according to googles development page. These are very interesting points because they can be relocatable to other aspects of computer science. Whether it is programming or deciding which algorithm is best for a certain scenario. These three key factors can help our understanding and visualization of future projects we may want to work on, which is why I choose this article. It helps detail each important aspect of user experiences and describes why these aspects need to be present.

First, let’s start of with reliability. By Google’s definition of reliable, “When launched from the user’s home screen, service workers enable a Progressive Web App to load instantly, regardless of the network state.”

This is a great viewpoint because you wouldn’t want your web-apps to load slow. By having the web-app load slow, it could alter the user’s experience – which is what our primary goal is to enhance. Determining ways that make items load faster can be a great challenge in itself. The article explains that pre-caching key resources can increase stability and enhance the user’s reliable experience because it eliminates the dependence of the app from the network. An example of this would be a service worker written in JavaScript that acts as a client-side proxy.

Google’s statistics mention that approximately 53% of users will abandon a website if it takes longer than 3 seconds to load. This data is interesting because it shows how far loading and caching algorithms and optimization have come. This also can have a big impact for monetized web-pages. If the page doesn’t load fast enough, the user could then leave, resulting in potential profit loss.

The final key point is engagement. An example of this would be your push notifications that you receive on a smartphone. Whenever the web-app wants to notify you of a change or a message, depending on what the web-app is, it sends notification to the home screen of your phone which in turn lessens the burden of opening the app itself. Small quality of life enhancements such as push notifications can really immerse a user in your product, and with a progressive web-app, that is our main goal. Knowing these main design principles of web-apps really helped me understand why and how we can further enhance user experience. Most of the time when we are developing something, it will be for the use of others, whether it’s internally or client based operation, reliability, speed, and engagement are all key aspects of creating a great web-app.
