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

There is also Jael, one of the few actively-developed HTML templating engines for Dart.

Angel support for Jael is provided through package:angel_jael.

Another is Jinja2, which was recently ported by to Dart byOlzhas Suleimen.

Angel support for Jinja2 can be found here:<https://pub.dartlang.org/packages/angel_jinja>

Example

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

ViewGenerator

Angel declares the following typedef:

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

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

1. import 'dart:io';
2. import 'package:angel_framework/angel_framework.dart';

4. Future<void> plugin(Angel app) async {
5. app.viewGenerator = (String path, [Map data]) async {
6. return "Requested view $path with locals: $data";
7. };
8. }

10. main() async {
11. var app = new Angel();
12. await app.configure(plugin);
13. await app.startServer();
14. }
