#Altar
A library for transforming and multiplexing file requests from the server using HTTP/2
Altar knows what files to Server Push by analyzing HTML requests for <link rel="preload" ... > as per the W3C spec https://www.w3.org/TR/preload/
You can define other transformer middleware that will transform and cache files into more efficient forms for delivery:
public/index.html
<html>
<head>
<!-- a flag for signalling to the backend to HTTP/2 server push this when this file is requested -->
<link rel="preload" href="/app.css" as="style">
<link rel="stylesheet" type="text/css" href="/app.css">
</head>
<body>
Hello World
</body>
<script>
//State is dynamically injected depending on the route
var state = {{STATE}};
console.log(state.message);
</script>
</html>...
const app = koa();
//Define static files location and middleware
app.use(altar({
root: 'public',
middleware: {
js: [altar.jsMinify],
css: [altar.cssMinify],
html: [altar.htmlHTTP2Send, altar.htmlMinify, altar.htmlRenderState],
},
}));
app.use(_.get('/', function* getPeople() {
altar.renderState(this, '/index.html', { message: 'You are on the home' });
}));
app.use(_.get('/people', function* getPeople() {
altar.renderState(this, '/index.html', { message: 'You are on the people' });
}));
app.use(_.get('*', function* getPeople() {
if (this.accepts('html')) {
altar.renderState(this, '/index.html', { message: 'You are on the 404' });
}
}));
