<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8" />
    <meta
      name="viewport"
      content="width=device-width, initial-scale=1.0, user-scalable=no, shrink-to-fit=no"
    />
    <title>index</title>
  </head>
  <body>
    <div id="root"></div>
    <script type="module" src="./index.jsx"></script>
  </body>
</html>
import React from "https://esm.sh/react";
import { createRoot } from "https://esm.sh/react-dom/client";

const root = createRoot(document.querySelector("#root"));
root.render(<div>{content}</div>, { content: "Hello World!" });

react app

only need create index.jsx

import React from "https://esm.sh/react";

function App({ content }) {
  return <div>{content}</div>;
}

export const title = "esmodule-server";

export default function main({ preloadedState }) {
  return React.createElement(App, { content: "Hello World!" });
}

react ssr app

implement export function getPreloadedState can open SSR, function getServerReady is useful server check whether data is ready, maximum try three times when return false.

import React from "https://esm.sh/react";

function App({ content }) {
  return <div>{content}</div>;
}

export const title = "esmodule-server";

const store = {
  content: "Hello World!",
  isLoaded: true,
};

export function getPreloadedState() {
  return { ...store };
}

export function getServerReady() {
  return store.isLoaded;
}

export default function main({ preloadedState = {} }) {
  Object.assign(store, preloadedState);
  return React.createElement(App, { content: store.content });
}

production and dev mode

  • ?dev add dev parameter to all link dependences, checkesm.sh, for example http://localhost:8000/example/react-ssr-app/index.html?dev
  • ?production add bundle parameter to all link dependences, checkesm.sh, in the meantime, bundle all the local script and minify them.

upcoming features
