Exalt SSR

A module to render web components on the server.

---

Installation

You can install @exalt/ssr using npm:

npm install @exalt/ssr

---

Getting Started

@exalt/ssr provides 2 functions to render web components on the server.

• loadBundle(path) - initalizes the DOM environment and loads the application bundle.
• renderToString(component, callback) - renders a component to a string.

The DOM environment provided is a subset of the DOM spec and is designed to render exalt components, however as long as the required apis are provided any web component can be rendered. @exalt/ssr will detect a components props and serialize them as a script tag in the markup.

When a shadow root is detected it will be rendered as a declarative shadow root.

Example - Rendering the app component

import { loadBundle, renderToString } from "@exalt/ssr";
import path from "path";

const bundlePath = path.join(process.cwd(), "dist", "index.js");

/* loadBundle returns the bundle exports, in this case it returns the App component */
const { App } = loadBundle(bundlePath);
const html = renderToString(new App());

console.log(html);

Example - Rendering the app component with callback

import { loadBundle, renderToString } from "@exalt/ssr";
import path from "path";

const bundlePath = path.join(process.cwd(), "dist", "index.js");

/* loadBundle returns the bundle exports, in this case it returns the App component */
const { App } = loadBundle(bundlePath);
const html = renderToString(new App(), (currentNode) => {
    console.log(`Rendering: ${currentNode.nodeName}`);
});

console.log(html);
