I am also one of the developers of the original Goo Create (worked on it between 2014 and the end of 2016) and I can confirm it is indeed the same app (including colors, icons, etc). Amazon basically just added some integrations with AWS and a new logo.

It is the evolution of it indeed. Amazon got the code after Goo Technologies went bankrupt, added some integrations with AWS and rebranded it.

As others have mentioned, this is all possible with Angular >=4, both in WebStorm and VSCode. The main issue is with performance and debugging. Using Angular's AoT compilation is still extremely slow and your squiggly lines take several seconds to show up after you modify a template in your editor. And no stepping through templates either when trying to debug why something isn't rendering properly.

But, imho, the biggest problem with Angular, by far, are it's NgModules. You can't just import a component normally and use it in your template. You need to also add it to an NgModule to make it available in the templates of the components inside that NgModule. And if for some reason you stop using a component, you need to remember to clean up the module as well since nothing will warn you about unused declarations or imports in NgModules.

And then there is also the fact that you can't directly import a function/constant and use it directly in the template because, like Components, the template engine needs to be told about it. So you need to add properties to your component class which are just providing access to things you imported above. So. Much. Pain.

Some people really like templating languages but imho just using TSX (which is just mapping to function calls) and normal ES modules is the best solution by far.
