React Router: What is the purpose of using <Outlet /> alone without context?-CodePudding

For what I understand now, if we pass an Outlet with context, the props after the context could be passed into child, and outlet act as a template that pass those props into any child the router may render.

My question is, what if we just set <Outlet /> without context? If it doesn't pass any props, is there any reason why we particularly want to use <Outlet /> alone?

Code may look like this

index.js

root.render(
  <BrowserRouter>
    <Routes>
      <Route path="/" element={<App />}>
        <Route path="checkout" element={<Checkout />} />
      </Route>
    </Routes>
  </BrowserRouter>
);

App.js

function App() {
  return (
    <>
      <Reset />
      <GlobalStyle />
      <Header cartItems={cartItems} />
      <Outlet />
    </>
  )
}

CodePudding user response：

The Outlet component alone allows nested routes to render their element content out and anything else the layout route is rendering, i.e. navbars, sidebars, specific layout components, etc.

<Routes>
  <Route path="/" element={<App />}>
    <Route path="checkout" element={<Checkout />} />
  </Route>
</Routes>

The Checkout component is rendered on "/checkout". The Reset, GlobalStyle, and Header components are all also rendered as part of the layout route "/" rendering App. I.E. something like the following is rendered to the DOM.

...
<Reset />
<Header cartItems={cartItems} />
<Checkout />
...
