I found no such logic in React Router 4 sources, so write own workaround:

<pre><code>import React, { Component } from 'react';
import PropTypes from 'prop-types';
import pathToRegexp from 'path-to-regexp';
import { Route, Redirect } from 'react-router-dom';

class RedirectWithParams extends Component {
 render() {
 const { exact, from } = this.props; 
 return (
 &lt;Route
 exact={exact}
 path={from}
 component={this.getRedirectComponent}
 /&gt;);
 }

 getRedirectComponent = ({ match: { params } }) =&gt; {
 const { push, to } = this.props;
 const pathTo = pathToRegexp.compile(to);
 return &lt;Redirect to={pathTo(params)} push={push} /&gt;
 }
};

RedirectWithParams.propTypes = {
 exact: PropTypes.bool,
 from: PropTypes.string,
 to: PropTypes.string.isRequired,
 push: PropTypes.bool
};

export default RedirectWithParams;
</code></pre>

usage example:

<pre><code>&lt;Switch&gt;
 &lt;RedirectWithParams
 exact from={'/resuorce/:id/section'}
 to={'/otherResuorce/:id/section'}
 /&gt;
&lt;/Switch&gt;
</code></pre>

Here's what I've been using, similar to the other answer but without a dependency:

<pre><code>&lt;Route
 exact
 path="/:id"
 render={props =&gt; (
 &lt;Redirect to={`foo/${props.match.params.id}/bar`} /&gt;;
 )}
/&gt;
</code></pre>

You can do this:

<pre><code>&lt;Switch&gt;
 &lt;Route exact path="/" component={Landing} /&gt;
 &lt;Route path="/channels/:channelId/modes/:modeId" component={Window} /&gt;
 &lt;Route
 exact
 path="/channels/:channelId"
 render={({ match }) =&gt; (
 &lt;Redirect to={`/channels/${match.params.channelId}/modes/window`} /&gt;

 /&gt;
&lt;/Switch&gt;
</code></pre>

I did this, and it worked:

<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>&lt;switch&gt;

 return &lt;Redirect to={`/signin`} /&gt;;
 } else {
 return &lt;Redirect to={`/anypath/${match.params.id}`} /&gt;;

&lt;/switch&gt;</code></pre>

You can do it using <a href="https://reactrouter.com/web/api/generatePath" rel="nofollow noreferrer"><code>generatePath</code></a>:
<pre><code>import { Switch, Route, Redirect, generatePath } from &quot;react-router&quot;;

&lt;Switch&gt;
 &lt;Route component={PageOne} path=&quot;/one&quot; /&gt;
 &lt;Route component={PageTwo} path=&quot;/two/:id&quot; /&gt;
 &lt;Route
 path=&quot;/three/:id&quot;
 render={props =&gt; (
 &lt;Redirect
 to={generatePath(&quot;/two/:id&quot;, {
 id: props.match.params.id,
 })}

 /&gt;
 &lt;Route component={NotFoundPage} path=&quot;*&quot; /&gt;

Short general version using <code>generatePath</code> that worked for me (redirecting from <code>from</code> path to <code>to</code> path, both having the same parameters):
<pre><code>import { Route, Redirect, generatePath } from &quot;react-router&quot;

&lt;Route path={from} 
 exact
 component={({match}) =&gt; 
 &lt;Redirect to={generatePath(to, match.params)} /&gt;} /&gt;
</code></pre>

I am using the <code>next</code> version of React Router, and it seems to be dropping params. I expect the redirect below to retain the value of <code>channelId</code>, but the <code>to</code> route uses the literal string "<code>:channelId</code>" in the path instead. 

<pre><code>&lt;Switch&gt;
 &lt;Route exact path="/" component={Landing} /&gt;
 &lt;Route path="/channels/:channelId/modes/:modeId" component={Window} /&gt;
 &lt;Redirect
 from="/channels/:channelId"
 to="/channels/:channelId/modes/window" /&gt;
&lt;/Switch&gt;
</code></pre>

This looks like a <a href="https://github.com/ReactTraining/react-router/issues/1034#issuecomment-113526156" rel="noreferrer">resolved issue</a>, but it's not working. Is there something else I need to pass to the <code>to</code> route?
