Recommendations for web stack for a learning project [on hold]

I'm planning to make a small WCF service monitoring app, this is an actual need I have in my work now. However, I'd like to step out of .NET Framework to learn an alternative way of programming things, a different viewpoint.

My plan is:

• Node/Express for backend/hosting
• Angular 2 for UI
• (I don't need database)

Are there any interesting new web frameworks that you could recommend for this learning purpose?

Thanks, Pom
