reactjs - Why do we need to render a component to issue a redirect in react-router?

In react-router v4 we now need to use a component to redirect the user to somewhere else.

While it makes sense when building the routes component (so a route can issue a redirection), it's very odd when, say, you have an error and must redirect somewhere, or redirect after a user action (that's not a simple link click).

Besides linking similar routes, redirections are also a reactive action, so why there's no API method for redirects, only a component?

Answer

Well there are some cases where is quite nice to use.

But, this is not a must.

There are many cases I created my "programmatically redirection" and you can use "history" that you get in props.

this.props.history.push('/dashboard')

if you don't have access to "history" in your props, as your component is not rendered inside the Route.

You can use the helper withRouter:

import {
  withRouter

} from 'react-router-dom'

and just wrap your component with it, and you will have the history accessable as a prop.

const yourComponent = props => {
    // this.props.history is here

    return 
 dont care 
;
}
