Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Works on Linux, Windows, Mac
Being powered by Javascript, apps build with Electron can be packed to run on all 3 platforms.
Pro Wide spread support
Javascript is a very easy language to learn, and is handy for all manner of other things. There's a good chance you already know it, or that you will need to know it in the future.
Pro WebApps without additional work
If you don't require native features and could write a web app (i.e. a website with dynamic elements), then you could just extend it and turn it into a native app. This means that people just need to type your URL to use you app and may get more by downloading and installing it.
Pro Complete IDE for GUI development
You can't find such a level of easy GUI development in any other language on the Linux platform.
Pro Constantly updated
New features and bug fixes along with performance enhancements.
Pro Easy to get started for someone familiar with VB on Windows
Pro Complete application development suite
Supports GTK and QT along with web. Built in Form building with JIT speed. If you are developing an application targeting Linux only give this a look.
Pro Fast to write apps
Pro Git integration
Integration with GIT in IDE and easy to distribute apps as source package with export as .tar.gz.
Pro Enhanced with a new test suite
Pro Runs on Windows 10 WSL2 environment, reported successful compilation on MacOS
Cons
Con Low performance
Electron applications use significantly more CPU, RAM, and disk space than applications written in almost any other framework. This results in poor battery life as well as an unpleasant user experience.
Con Backwards incompatibility between versions
Electron is growing and constantly changing, but there is no care whatsoever whether the changes in a new version will break your application or not. Even if you write and maintain one app, changes to how Electron handles JS files and functions will make maintenance of a single app your full time job. Even the development process, programming mindset and tooling changes between versions, so there is no guarantee that your app will even have a proper architecture a year from when you've built it.
Con Not cross platform
Con The documentation is not the best
Con May have trouble interfacing to C code structs
Managed struct objects in Gambas makes it harder to use with C code structs.
Con Difficult to satisfy runtime requirements
Runtime requirements to run applications written in Gambas are not always easy to satisfy (that is, without installing the whole development environment).
