# seo
|
|
Helpers for building SEO-friendly Web pages in Angel. The goal of
|
|
`package:angel_seo` is to speed up perceived client page loads, prevent
|
|
the infamous
|
|
[flash of unstyled content](https://en.wikipedia.org/wiki/Flash_of_unstyled_content),
|
|
and other SEO optimizations that can easily become tedious to perform by hand.
|
|
|
|
## `inlineAssets`
|
|
This function is a simple one; it wraps a `VirtualDirectory` to patch the way it sends
|
|
`.html` files.
|
|
|
|
In any `.html` file sent down, `link` and `script` elements that point to internal resources
|
|
will have the contents of said file read, and inlined into the HTML page itself.
|
|
|
|
In this case, "internal resources" refers to a URI *without* a scheme, i.e. `/site.css` or
|
|
`foo/bar/baz.js`.

|

import 'package:angel_framework/angel_framework.dart';
|
|
import 'package:angel_seo/angel_seo.dart';
|

import 'package:angel_static/angel_static.dart';
|
|
import 'package:file/local.dart';

|
|
main() async {
|
|
var app = new Angel()..lazyParseBodies = true;
|
|
var fs = const LocalFileSystem();
|
|
var http = new AngelHttp(app);
|
|
|
|
var vDir = inlineAssets(
|
|
new VirtualDirectory(
|
|
app,
|
|
fs,
|
|
source: fs.directory('web'),
|
|
),
|
|
);
|
|
|
|
app.use(vDir.handleRequest);
|
|
|
|
app.use(() => throw new AngelHttpException.notFound());

var server = await http.startServer('127.0.0.1', 3000);
|
|
print('Listening at http://${server.address.address}:${server.port}');
|
|
}
