Redirects in React Router v6

An important part of "routing" is handling redirects. Redirects usually happen when you want to preserve an old link and send all the traffic bound for that destination to some new URL so you don't end up with broken links.

The way we recommend handling redirects has changed in React Router v6. This document explains why.

Background

In React Router v4/5 (they have the same API, you can read about why we had to bump the major version here) we had a <Redirect> component that you could use to tell the router when to automatically redirect to another URL. You might have used it like this:

import "babel-polyfill";

const asyncQuerySelector = async (node, query) => {
  try {
    return await (query ? node.querySelector(query) : node);
  } catch (error) {
    console.error(`Cannot find ${query ? `${query} in`: ''} ${node}.`, error);
    return null;
  }
};
