The libraries and tools that inspired StellarAdmin
Acknowledgements
shadcn/ui
As mentioned in the introduction, StellarAdmin is based on shadcn/ui. The majority of the styling and component structures were lifted as-is from shadcn/ui.
Although StellarAdmin is inspired by and based on shadcn/ui, it does not follow its core principle.
You see, shadcn/ui is not a traditional library that you reference, but rather it copies the source code for all components into your project, allowing you to "own" and extend the components as you please. It is really a component distribution system that allows you to install the source code for components from various sources (called registries) into your own application.
StellarAdmin is just a traditional component library that you reference via a NuGet package. However, it is based on the shadcn/ui styling which has two main advantages:
- It provided a starting point for beautiful CSS styling for the various components. This saved me a lot of time during the development as I could, for the most part, simply copy the styles from the shadcn/ui components and did not have to wrestle with creating the styles myself.
- It gave StellarAdmin a familiar visual language. StellarAdmin has since moved to its own theming system of CSS variables, but its components still follow the shadcn/ui anatomy.
Tailwind CSS
StellarAdmin was originally built on top of Tailwind CSS, like shadcn/ui. Tailwind CSS is a utility-first CSS framework that provides a set of pre-designed classes, like flex, pt-4, and text-center, that can be composed directly in your HTML to rapidly build custom user interfaces without writing custom CSS. The Tag Helpers' stylesheet is now plain CSS, and a Tailwind adapter lets your own Tailwind build use StellarAdmin's design tokens.
Lucide
Lucide is an open-source icon library and is used by StellarAdmin in <sa-icon> and several other Tag Helpers.
Fumadocs
This website you are reading now is built using Fumadocs. Fumadocs is a React-based framework that allows you to rapidly create documentation websites. It saved me a lot of time by giving me a solid framework and a beautiful website design.
Other UI libraries
In the course of building StellarAdmin and researched many other UI libraries for inspiration and some of them may have influenced some of the design decisions I made.
- Mantine - a UI library for React.
- Flux - a UI library for Laravel Livewire using Tailwind CSS.
- Pinemix - a UI library based on Tailwind CSS and Alpine.js.
- Penguin - a UI library based on Tailwind CSS and Alpine.js.
- Pines UI - a UI library based on Tailwind CSS and Alpine.js.
- Bits UI - a headless UI library for Svelte.
- Sailboat UI - a UI library based on Tailwind CSS.
- Flowbite - a UI library based on Tailwind CSS.
