galileo_twig_dart 3.0.2

Galileo support for the twig_dart templating engine, similar to Blade or Liquid.

twig_dart

galileo support for twig.

Installation

In your pubspec.yaml:

dependencies:
  galileo_twig: ^3.0.0

Usage

Just like mustache and other renderers, configuring galileo to use twig is as simple as calling app.configure:

import 'package:galileo_framework/galileo_framework.dart';
import 'package:galileo_twig/galileo_twig.dart';
import 'package:file/file.dart';

galileoConfigurer myPlugin(FileSystem fileSystem) {
    return (galileo app) async {
        // Connect twig to your server...
        await app.configure(
        twig(fileSystem.directory('views')),
      );
    };
}

package:galileo_twig supports caching views, to improve server performance. You might not want to enable this in development, so consider setting the flag to app.isProduction:

twig(viewsDirectory, cacheViews: app.isProduction);

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 twig templates from a directory named views:

import 'package:galileo_framework/galileo_framework.dart';
import 'package:galileo_twig/galileo_twig.dart';
import 'package:file/local.dart';
import 'package:logging/logging.dart';

main() async {
  var app = new galileo();
  var fileSystem = const LocalFileSystem();

  await app.configure(
    twig(fileSystem.directory('views')),
  );

  // Render the contents of views/index.twig
  app.get('/', (res) => res.render('index', {'title': 'ESKETTIT'}));

  app.use(() => throw new galileoHttpException.notFound());

  app.logger = new Logger('galileo')
    ..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:twig_preprocessor.
