Rendering Views

Rendering Views

Just like res.render in Express, Angel's ResponseContext exposes a Future called render. This invokes whichever function is assigned to your server's viewGenerator.

There is a Mustache templating plug-in for Angel available: https://github.com/angel-dart/mustache

However, it is strongly recommended that you use Jael, the only actively-developed HTML templating engine for Dart.

Angel support for Jael is provided through package:angel_jael.

Example

app.get('/view', (req, res) async => await res.render('hello', {'locals': ['foo', 'bar']});

ViewGenerator

Angel declares the following typedef:

/// A function that asynchronously generates a view from the given path and data.
typedef Future<String> ViewGenerator(String path, [Map data]);

A templating plug-in can assign one of these to app.viewGenerator to set itself up:

import 'dart:io';
import 'package:angel_framework/angel_framework.dart';
Future plugin(Angel app) async {
app.viewGenerator = (String path, [Map data]) async {
return "Requested view $path with locals: $data";
};
}
main() async {
Angel app = new Angel();
await app.configure(plugin);
await app.startServer();
}
