Quick look: Electron vs Qt/QML app memory usage
In time of COVID-19 there is much less things to do if your country rules are to stay at home.
If you are lucky enough that you can work from home probably you have a bit more time that you need to fill with something that is not movies, games or eating.
One of those could be looking at what next framework you would use and if memory usage of that app should be any concern for you.
If all frameworks give you the same, should you choose the one that is more lightweight or should you wait for that bug report telling that memory usage of your app is too big and you need to optimize it? After all people can use RPI devices as a PC.
I worked quite a lot on optimizing apps that were written poorly and used too much memory. Those scenario today, in my experience, inevitably happen. Everyone is targeting to deliver more in less time and then performance and memory usage of an app usually become secondary…until they don’t.
But even in other cases putting yourself in a better starting position should be a sane choice. You don’t necessarily want your app being remembered as a ‘memory hog’, even if it is a very popular and successful ‘memory hog’.
But how much of a difference can a framework choice really make?
Qt/QML
QML is a declarative language that allows user interfaces to be described in terms of their visual components and how they interact and relate with one another. It is a highly readable language that was designed to enable components to be interconnected in a dynamic manner, and it allows components to be easily reused and customized within a user interface.
Having more than 6+ years of experience in using QML and still writing about it means that I still think it’s a great framework.
It’s cross-platform, use declarative language to write UI and is performant.
There is many ready modules that one can choose from and it is used to develop apps ranging from embedded to mobile.
It also compiles to a native app which should arguably perform better than a web app.
