next/link
should be able to cover most of your routing needs, but you can also do client-side navigations without it, take a look at the Router API documentation.
The following example shows the basic usage of the Router API:
import Router from 'next/router'
function ReadMore() {
return (
<div>
Click <span onClick={() => Router.push('/about')}>here</span> to read more
</div>
)
}
export default ReadMore
