|
[Angel 3](https://pub.dev/packages/angel3_framework) support for [Jael 3](https://pub.dev/packages/jael3).
|
|
|
|
## Installation
|
|
|
|
In your `pubspec.yaml`:
|
|
|
|
```yaml
|
|
dependencies:
|
|
angel3_jael: ^4.2.0
|
|
```
|
|
|
|
## Usage
|
|
|
|
Just like `mustache` and other renderers, configuring Angel to use Jael is as simple as calling `app.configure`:
|
|
|
|
```dart
|
|
import 'package:angel3_framework/angel3_framework.dart';
|
|
import 'package:angel3_jael/angel3_jael.dart';
|
|
import 'package:file/file.dart';
|
|
|
|
AngelConfigurer myPlugin(FileSystem fileSystem) {
|
|
return (Angel app) async {
|
|
// Connect Jael to your server...
|
|
await app.configure(
|
|
jael(fileSystem.directory('views')),
|
|
);
|
|
};
|
|
}
|
|
```
|
|
|
|
`package:angel3_jael` supports caching views and minified html output by default, to improve performance. You might want to disable them in development, so consider setting these flags to `false`:
|
|
|
|
```dart
|
|
jael(viewsDirectory, cacheViews: false, minified: false);
|
|
```
|
|
|
|
Keep in mind that this package uses `package:file`, rather than `dart:io`.
|
|
|
|
The following is a basic example of a server setup that can render Jael templates from a directory named `views`:
|
|
|
|
```dart
|
|
import 'package:angel3_framework/angel3_framework.dart';
|
|
import 'package:angel3_jael/angel3_jael.dart';
|
|
import 'package:file/local.dart';
|
|
import 'package:logging/logging.dart';
|
|
|
|
void main() async {
|
|
var app = Angel();
|
|
var fileSystem = const LocalFileSystem();
|
|
|
|
await app.configure(
|
|
jael(fileSystem.directory('views')),
|
|
);
|
|
|
|
// Render the contents of views/index.jael
|
|
app.get('/', (res) => res.render('index', {'title': 'ESKETTIT'}));
|
|
|
|
app.use(() => throw AngelHttpException.notFound());
|
|
|
|
app.logger = Logger('angel')
|
|
..onRecord.listen((rec) {
|
|
print(rec);
|
|
if (rec.error != null) print(rec.error);
|
|
if (rec.stackTrace != null) print(rec.stackTrace);
|
|
});
|
|
|
|
var server = await app.startServer(null, 3000);
|
|
print('Listening at http://${server.address.address}:${server.port}');
|
|
}
|
|
```
|
|
|

To apply additional transforms to parsed documents, provide a set of `patch` functions, like in `package:jael3_preprocessor`.
