React Across

API:

• hydrate: Requery the page and initialize new widgets.

function hydrate(): void;

• render: Alternative to ReactDOM.render() Pass in a container element and optionally a Wrapper component (to be used for Redux Providers for example.)

interface Renderer {
  container: Element | null;
  Wrapper?: React.FC;
  callback?: () => void;
}
function render({ container, Wrapper, callback }: Renderer): void;

• registerComponent: Used to register React components, can optionally pass in a loader element that will be displayed when the element is fetched.

type LazyReactEl = React.LazyExoticComponent<AcrossComponent>;
function registerComponent({
  identifier,
  Component,
  Loader,
  errorBoundaryProps,
}: {
  identifier: string;
  Component: React.LazyExoticComponent<AcrossComponent> | AcrossComponent;
  errorBoundaryProps?: ErrorBoundaryProps // See: https://github.com/bvaughn/react-error-boundary
  Loader?: React.ReactNode;
}): void;

Components imported using React.lazy will be loaded on demand, regular imports will result in the component included in the main bundle.

Usage

Register components:

import { registerComponent } from "@foreachbe/react-across";
const Widget = React.lazy(() => import("./Widget"));
registerComponent({ identifier: "my-cool-widget", Component: Widget });

Render out the main entrypoint after importing the desired widgets:

import { render } from "@foreachbe/react-across";
import "./widgets";

const rootEl = document.querySelector("#root");

render({ container: rootEl });

Add HTML with the following markup to get hydrated with react widgets:

<!-- Somewhere in the dom -->
<div id="root"></div>
<!-- Somewhere else on the page. -->
<div data-component="my-cool-widget" data-props-test="value to be passed to react"></div>
