Well, thank you for the introduction… To all who read this and become curious. UI5 is the last what I would choose for UI. It's not truly opensource, wannabe modern, etc. But no Typescript, no HMR, no Treeshaking, no any sane UI tools, documentation is incomplete, crazy obstacles if you wanna define own component, etc. etc. So better keep you hands off it. Really!
Hi vilinski, this is not really a constructive comment :D
SAPUI5 is not Open Source you are right but SAPUI5 is based on OpenUI5 that is totally open source. SAPUI5 has just a couple of UI controls more than OpenUI5 that are not yet open source released but it's just a matter of time.

You always need to remember a couple of things. SAP is for enterprises and enterprise companies are different in needs compared to startup, projects and so on what you really want is stability and security and you cannot make huge shifts of tech without thinking about it twice. Also remember that enterprise companies relies always on Internet Explorer and when we're talking about that browser every new cool things are not supported.

SAPUI5 1.6.x is the latest version that will support that browser so I think that they will make some huge changes after that release cycle.

So yes, I think that SAPUI5 is still far behind if compared to other web framework like Vue, Angular or React but they are different products for different markets. You cannot find something better than SAPUI5 if you need to work with SAP ecosystem or with enterprise echosystem in general.

About the documentation, tools and resources you are wrong. SAP has made a huge investment about it and about the community. If you look at my first blog post on Habr "What do you need to start learning SAPUI5?" you can find all the answers.

I'm not a SAP employee so mine is the opinion of a consultant that perfectly know the state of the art of front/back end development nowadays.
Sorry if I'm scaring your customers away. I'm not an SAP employee either. I'm just stinky because I'm forced to use it now. Using it with SAP ecosystem is probably the only way you can convince any naive manager to force their devs to use it in development. SAP in general is infamous for it's user findly interfaces, not just outdated or not responsive. And any comments about enterprise in general are not constructive too. There are many examples where enterprises are doing much better than that, and if not — it's their legacy problem what you call «different market». Didn't see any security features in UI5 until now, which are not existed anywhere else for years. What you speaking about? Is using naked JS any secure? Look to the SAP own blog entry here, scroll to disadvantages: blogs.sap.com/2017/03/04/side-by-side-sapui5-vs.-react-angular2 It's not such old. What has happened to UI5 in this time period? Nothing. What about react and angular? They are literally newborn since then. If you know perfectly the state of the art of development nowaday, you probably know about even better alternatives.
Hi vilinski that blog post is on SCN (SAP Community Network) but it's not from SAP itself, it's from a community member (like me or like you) because SAP allows everyone to express an opinion.

As I said, when you work in an enterprise envoirnment innovation is slow. SAPUI5 is evolving too, maybe slower than Angular, Vue or React but it's evolving but it's also true that it's used in much different use case.

A lot of blog post about the evolution can be found here: blogs.sap.com/tag/ui5-evolution
