What this rule does

On MacOS, cmd-tab only toggles between different apps. To toggle between different windows of the same app, you need to use cmd-` . However this is cumbersome for regular usage, as it requires stretching your fingers unnaturally. This rule allows to use cmd-CapsLock instead, which is much easier.

To enable the rule

Install Karabiner Elements and give it all permissions it asks for
cd ~/.config/karabiner/assets/complex_modifications and put the json file below there
Restart Karabiner Elements
Go to "Complex Modifications > Add rule"

Composing `<Route>` in React Router v6

Composition of <Route> elements in React Router is changing in v6 from how it worked in v4/5 and in Reach Router. React Router v6 is the successor of both React Router v5 and Reach Router.

This document explains our rationale for making the change as well as a pattern you will want to avoid in v6 and a note on how you can start preparing your v5 app for v6 today.

Background

In React Router v5, we had an example of how you could create a element](https://github.com/remix-run/react-router/blob/320be7afe44249d5c025659bc00c3276a19f0af9/packages/react-router-dom/examples/Auth.js#L50-L52) to restrict access to certain routes on the page. This element was a simple [wrapper around an actual element that made a simple decision: is the user authenticated or not? If so, ren
