When using TypeScript with moduleResolution "node16" or "nodenext", importing clsx and using it:

```ts import clsx from 'clsx';

clsx('a', 'b', 'c'); ```

produces the following error:

``` src/index.tsx(3,0): error TS2349: This expression is not callable. Type 'typeof import("/node_modules/clsx/clsx")' has no call signatures. ```

It appears the problem is with the way typings are shipped with this library. Please read: https://github.com/microsoft/TypeScript/issues/49189#issuecomment-1137756847

The thread also mentions the same problem with classnames package, but it appears that they have dealt with it since then.
