So, what IS electron, exactly?

electron is a framework that lets developers create applications using web technologies, like javascript, HTML or CSS. It's open source, and it's cross platform, meaning that apps built with electron run on Windows, Mac and Linux.
ectly inside of the app, instead of being accessed on the internet.

So why do developers go the electron route?

Developing apps using native technologies on all platforms takes a long time, a different set of skills and knowledge for each platform, and so you need more developers, more time, and more money.

Electron lets you develop ONCE.

Second reason: debugging code for web technologies like javascript is pretty easy compared to lower level languages like C, C++, or objective C. Javascript is interpreted line by line, so noticing where the error is is way easier.


Another reason is that electron apps can auto update very easily: all you have to do is make sure that your electron app can detect when the code for your website has changed, and download the new files on your computer, a quick reload of the page, and you're up to date.

But, electron has a bunch of issues as well.

First, electron doesn't integrate really well with the operating system: it's just a web browser displaying a website that is stored on your computer instead of being stored on a server. This means that if electron doesn't support a specific feature of your operating system, the apps using it also won't.

A bigger problem, though, is the fact that developers often don't update the electron base, or not often enough. Electron, using CHromium, needs to be as up to date as any web browser you'd use everyday, to ensure that security flaws are patched.

That's often not the case. And it gets worse when you take into consideration operating system integration. An example is Discord on Linux. It uses an older version of electron, that doesn't support Wayland very well. electron does have wayland support, and good support at that, but Discord, by not updating the electron version they use, deprive users of that support.

And then there's the performance and resource usage. Since electron apps ship basically the whole of chromium's codebase, they aren't small. Discord, for example, once installed, weighs more than 700 MB. Almost a gigabyte. Even the most basic of Hello World applications would take about 100MB, just to display a line of text.

And there's the performance impact: chromium isn't a lighweight browser at all. Discord, again, on my system, with all its processes, uses about 480 MB. And that RAM usage is the same whether the app is minimized to the tray or fully open. GIMP, when opening a new blank document, uses 500MB.

And still, specifically for us Linux users, electron means we get applications on Linux that we wouldn't have had otherwise.
