NPM travis-ci

Render JSX and Preact components to an HTML string.

Works in Node & the browser, making it useful for universal/isomorphic rendering.

>> Cute Fox-Related Demo (@ CodePen) <<


Render JSX/VDOM to HTML

import render from 'preact-render-to-string';
import { h } from 'preact';
/** @jsx h */
 
let vdom = <div class="foo">content</div>;
 
let html = render(vdom);
console.log(html);
// <div class="foo">content</div>

Render Preact Components to HTML

import render from 'preact-render-to-string';
import { h, Component } from 'preact';
/** @jsx h */
 
// Classical components work
class Fox extends Component {
    render({ name }) {
        return <span class="fox">{ name }</span>;
    }
}
 
// ... and so do pure functional components:
const Box = ({ type, children }) => (
    <div class={`box box-${type}`}>{ children }</div>
);
 
let html = render(
    <Box type="open">
        <Fox name="Finn" />
    </Box>
);
 
console.log(html);
// <div class="box box-open"><span class="fox">Finn</span></div>

Render JSX / Preact / Whatever via Express!

import express from 'express';
import { h } from 'preact';
import render from 'preact-render-to-string';
/** @jsx h */
 
// silly example component:
const Fox = ({ name }) => (
    <div class="fox">
        <h5>{ name }</h5>
        <p>This page is all about {name}.</p>
    </div>
);
 
// basic HTTP server via express:
const app = express();
app.listen(8080);
 
// on each request, render and return a component:
app.get('/:fox', (req, res) => {
    let html = render(<Fox name={req.params.fox} />);
    // send it back wrapped up as an HTML5 document:
    res.send(`<!DOCTYPE html><html><body>${html}</body></html>`);
});
