# shadcn-ui/cn

> An engine for Tailwind class merging and conflict resolution that replaces tailwind-merge and clsx with the same APIs and full parity, but 30× faster.

## Useful for

- Replace tailwind-merge and clsx in an existing project with one migration command
- Speed up component rendering with frequent cn() calls in large codebases
- Configure custom Tailwind classes via createCn with extend and prefix

## Why it’s here

- There are not enough fresh counter measurements for today's UTC day. The gain is unknown.
- The repository is 40 days old and already has 1,654 stars.

## Star trust

Star growth looks organic.
- Fewer forks than usual: 18 for 1,654 stars.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 18
- Issues and pull requests: 52
- Watchers: 1
- Average over the last week: 5 per day

---

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
