Nebular is a customizable Angular UI Library based on Eva Design System specifications, with 40+ UI components, 4 visual themes, Auth and Security modules.
While looking for some good angular UI libraries except Material Design, I stumbled across Nebular.
Being based on Eva Design, the UI components are really clean and user experience focused.
One thing where Nebular stands out from other libraries is that Nebular modules are distributed as separate npm packages.
Nebular not only has UI components like form-control, buttons and all, but also has the security module, Auth module. Thus, acting as single source of multi-use components for angular applications.
The github repo for nebular has 5218 stars as of 10 Sept, 19 and has 80% typescript, which is understandable being an angular based component-library.
I love using this library in my side-projects, and hope to contribute to it soon.
