React-Router open Link in new tab

I think Link component does not have the props for it.

You can have alternative way by create a tag and use the makeHref method of Navigation mixin to create your url

<a target='_blank' href={this.makeHref(routeConsts.CHECK_DOMAIN, {},
   { realm: userStore.getState().realms[0].name })}>
        Share this link to your webmaster
</a>

Since React Router version 5.0.1, you can use:

<Link to="route" target="_blank" rel="noopener noreferrer" />
