Bracoa provides a simple interface for JavaScript server side rendering in PHP.
- php7.1
- V8Js
composer require koriym/baracoa
In a JS renderer application, implement render function which takes parameter(s) and return html string.
const render = state => (
`Hello ${state.name}`
)Call the render() method with JS app name and values to assign to redner.
$baracoa = new Baracoa($jsDir, new ExceptionHandler());
$html = $baracoa->render('min', ['name' => 'World']);
echo $html; // Hello WorldIn this example, you need to place min.bundle.js JS file in $jsDir directory.
Every page needs own JS view application which is bundled single file by bundler tool like webpack.
Typical entry file is like following code.
import render from './render';
global.render = render;
In next section we see the example of Redux with React applicaiton example.
Inject an initial component HTML and initial state into a template to be rendered on the client side.
To pass along the state, we add a <script> tag that will attach preloadedState to window.__PRELOADED_STATE__.
The preloadedState will then be available on the client side by accessing window.__PRELOADED_STATE__.
We also include our bundle file for the client-side application via a <script> tag.
This is whatever output your bundling tool provides for your client entry point.
import React from 'react';
import { renderToString } from 'react-dom/server';
import { Provider } from 'react-redux';
import escape from 'escape-html';
import serialize from 'serialize-javascript';
import App from '../containers/App';
import configureStore from '../store/configureStore';
const render = (preloadedState, metas) => {
const store = configureStore(preloadedState);
const root = renderToString(
<Provider store={store}>
<App />
</Provider>,
);
return `<!doctype html>
<html>
<head>
<title>${escape(metas.title)}</title>
</head>
<body>
<div id="root">${root}</div>
<script>
window.__PRELOADED_STATE__ = ${serialize(preloadedState)}
</script>
<script src="/build/index.bundle.js"></script>
</body>
</html>
`;
};
export default render;render() method can pass second parameter as SSR meta data which is only available in server side rendering. Typically this value is used in <header> such as for OGP.
$meta = ['title => 'awesome page'];
$html = $baracoa->render('min', ['name' => 'World'], $meta);We need to do is grab the initial state from window.__PRELOADED_STATE__ which is rendered in server side, and pass it to our createStore() function as the initial state.
import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux';
import configureStore from '../store/configureStore';
import App from '../containers/App';
const preloadedState = window.__PRELOADED_STATE__;
const store = configureStore(preloadedState);
render(
<Provider store={store}>
<App />
</Provider>,
document.getElementById('root'),
);$cache = new FilesystemCache() // PSR-16
$baracoa = new CacheBaracoa($appBundleJsPath, new ExceptionHandler(), $cache);An external "snapshot" is saved to increase performance in each app with CacheBaracoa.
Highly recommended in production site.
Consider internal snapshot for more performance.
