Build Status


Jaguar, a server framework built for speed, simplicity and extensiblity.

Advantages of Jaguar

  1. Keeps your route handlers concise and clean
  2. Bare metal speed achieved through code generation
  3. Extensible interceptor infrastructure
  4. Generates API console client to try your server without writing singleline of client code
  5. Tests are first class citizens in jaguari. Mock HTTP requests and Websocket requests ii. Use dependency injection to test your API
  6. Optional Firebase/Parse like no code or little code servers

Even though Jaguar is feature rich, it is simpler and easy to get started.


Simple routes

/// File: main.dart
library jaguar.example.silly;

import 'dart:async';
import 'dart:io';
import 'package:jaguar/jaguar.dart';

part 'main.g.dart';

/// Example of basic API class
@Api(path: '/api')
class ExampleApi extends _$JaguarExampleApi {
  int _pingCount = 0;

  /// Example of basic route
  @Route('/ping', methods: const <String>['GET'])
  String ping() => "You pinged me ${++_pingCount} times, silly!";

  /// Example of setting default status code and headers in response
      methods: const <String>['POST'],
      statusCode: 201,
      headers: const {"pong-header": "silly-pong"})
  String pong() => "Your silly pongs have no effect on me!";

  /// Example of getting path parameter in route handler arguments
  @Route('/echo/pathparam/:message', methods: const <String>['POST'])
  String echoPathParam(String message) => message ?? 'No message :(';

  /// Example of getting query parameter in route handler arguments
  @Route('/echo/queryparam', methods: const <String>['POST'])
  String echoQueryParam({String message}) => message ?? 'No message :(';

Future<Null> main(List<String> args) async {
  ExampleApi api = new ExampleApi();

  Configuration configuration = new Configuration();

  await serve(configuration);
