FAQPage Schema
How do I install a COSS UI particle component?

Find the particle in the index by component type, then fetch its JSON manifest at https://coss.com/ui/r/<particle-name>.json. The JSON contains the full source code, which you copy into your project and adapt to your needs.

What component types are available in COSS UI particles?

The index covers 54 component types with 508 total particles, including button, input, dialog, drawer, calendar, combobox, select, slider, table, tabs, toast, and form patterns. Each type contains multiple variants such as sizes, states, and composed layouts.

Does COSS UI particles work with Tailwind CSS and React?

Yes, particles are built on COSS UI primitives, which are Base UI components styled with Tailwind CSS v4. They are designed for React projects and require COSS UI components installed in the project first.

Can I use COSS particles without installing COSS UI primitives?

No, particles depend on COSS UI primitives being present in your project. The compatibility requirement states that COSS UI components must be installed before particle source code will work correctly.

How is the COSS particle index updated?

The index is regenerated by running node apps/ui/scripts/generate-particle-index.cjs from the coss repository root. Particle source files live in apps/ui/registry/default/particles/ within that repository.
