PWA are they really reliable?

Hey there and welcome back to another blog
by Hussey Coding.


PWA's are all the rage right now, it's what most people in the world of web and technology are talking about. If you've been following us here at Hussey Coding, you'll know that we're also talking about this new development.

Over the last few weeks, we've taken a look at what PWA's are? (PWA - What's all the fuss about?), they're speed (PWA speed - Websites vs PWA) and recently what they are like to interact with (Interacting with PWA). Today we will ask a new question of PWA's, having all the speed and appearance of a native app is great but what we really want to know is ...

Maybe a better way to answer this question is to first ask what is it to be reliable? According to the dictionary, reliability is

 "the quality of being trustworthy or of performing consistently well."

So the question we are really asking here is, do PWA's perform consistently well?

We all know that the mobile web browser doesn't always deliver in this department. How often have we gone to our favourite store or site just to see the very cute yet very frustrating downasaur?

You don't really get that so much with native apps. But it can often be the case that on your commute or during lunch, you go to use your favourite app, to find that you need to download the newest version, which takes up all your time!

PWA's look to combat both these issues and more!

As frustrating as it is seeing the downasaur, it's even more frustrating when it's displaying on your website. With the average person abandoning the site altogether after the first 3 seconds, you could be losing out on valuable sales and traffic.


One of the best things about PWA's is that they work offline, yes you read right, they work offline! 

They do this by saving some of the app's resources in the cache, meaning that they will always be accessible and run smoothly and quickly. Now it's important to point out that maybe not every single part of the PWA will be accessible, but you'll still get that desktop-level speed and reach to those areas that are, giving your users the ability to browse, add to cart and in some cases even purchase items all while being offline! 

They also update themselves! I say they update themselves; what I really mean is that developers do all the updating behind the scenes (like the coding ninja's they are). This means that the user doesn't need to keep downloading updates all the time. 

In fact, as soon as a users mobile device connects to the internet, the PWA will begin to update automatically in the background. This means that the next time the user opens up the PWA, it will be the latest, most up to date version of that app! The only caveat here is the user may need to grant the app permission to do so in their settings.

BUT WAIT, there's more! Since this is a web application, all of the updates will be accessible to anyone with an internet connection regardless of device, model or web browser!

If you've been with us for a while now, you'll have been reading our series on cybersecurity. Looking at how important it is, our list of common cyber attacks to look out for and our list of things to help you better secure your stores. If you missed any of them, we've posted the links to the series below.


With this in mind, is PWA secure? Being a hybrid of web and native can they be secure? The answer is yes! A tremendous advantage to PWA is that they originate on the web, which means they have HTTPS access, this is an important step up in security over native apps. Obviously, cybersecurity is never guaranteed, even the most secure of sites and stores come under attack and at some point hackers will go after PWA, but for the moment, those little magic padlocks are there to help.
