Usage

Server

  Dream.router([
    Dream.get("/", _request => {
      let portals: ref(array(UniversalPortal_Shared.Components.Portal.portal)) = ref([||]);

      let element =
        ReactDOM.renderToString(
          UniversalPortal_Server.collectPortals(
            <Page scripts=["/static/app.js"]>
              <Shared_native_demo.App />
            </Page>,
            (collectedPortal: UniversalPortal_Shared.Components.Portal.portal) => {
            portals := Array.append(portals^, [|collectedPortal|])
          }),
        );

      let html =
        UniversalPortal_Server.appendUniversalPortals(element, portals^);

      portals := [||];

      html |> Dream.html;
    }),
    Dream.get("/static/**", Dream.static("./static")),
  ]);

Shared

For client dune config add

 (libraries universal-portal.shared_js)

For native dune config add

 (libraries universal-portal.shared_native)

Component

Use UniversalPortal_Shared and it will work on both client and native content.

[@react.component]
let make = () => {
  <div>
    <UniversalPortal_Shared.Components.Portal selector="body">
      <div>
        {"Hey, I'm a portal, disable JS on your dev tools and check that I'll still here"
          |> React.string}
      </div>
    </UniversalPortal_Shared.Components.Portal>
  </div>;
};

Cleaning server side portals

You must call the UniversalPortal_Shared.Hooks.UseRemoveServerPortals.make at the main entry point of your app, so it will remove all the server side portals.

Checkout the demo for more details: Demo

  UniversalPortal_Shared.Hooks.UseRemoveServerPortals.make();
