Sever side usage with Koa

First, let's create our component to render boilerplate HTML, header, body etc.

import Koa from 'koa';
import { renderToString } from 'inferno-server';
import { Switch, StaticRouter, Route } from 'inferno-router';

const app = new Koa();

function Index({children}) {
  return (
    <html>
    <head>
      <meta charSet="utf-8"/>
      <title>Inferno</title>
    </head>
    <body>
    <div id="app">{children}</div>
    </body>
    </html>
  )
}

// Example routes
function Home() {
  return <div>Welcome Home!</div>
}

function Foo() {
  return <span>Bar</span>
}

function NotFound() {
  return <h2>404</h2>;
}

const routes = (
  <Switch>
    <Route exact path="/" component={Home}/>
    <Route exact path="/demo" component={Foo}/>
    <Route path="*" component={NotFound}/>
  </Switch>
);

// Server-side render
async function render(ctx, next) {
  const context = {};
  const content = renderToString(
    <StaticRouter location={ctx.url} context={context}>
      <Index hostname={ctx.hostname}>
        {routes}
      </Index>
    </StaticRouter>
  );

  // This will contain the URL to redirect to if <Redirect> was used
  if (context.url) {
    return ctx.redirect(context.url);
  }

  ctx.type = 'text/html';
  ctx.body = '<!DOCTYPE html>\n' + content;
  await next();
}

// Add infero render as middleware
app.use(render);


app.listen(8080, function () {
  console.log('Listening on port ' + 8080);
});

Differences with React-Router v4

No "official" react-native support.
There's no inferno-router-dom, all functionality is inside inferno-router
