arowana
a lightweight http server framework for dart.it is based on the shelf library for handling http requests and implements a high-performance routing with reference to golang’s gin framework.
usage
a simple usage example:
import 'dart:isolate';
import 'package:arowana/arowana.dart';
class myachannel extends defaultchannel{
@override
future prepare() {
print('current isolate [${isolate.current.debugname}]');
return super.prepare();
}
@override
void entrypoint() {
get('/hello', (r){
return response.ok('hello,arowana!');
});
}
}
void main() {
var app = application(myachannel());
app.start(numberofinstances: 2,consolelogging: true);
}
another example, containing grouped routes:
class myachannel extends appchannel {
router app = router();
middleware verification() => (innerhandler) {
return (request) async {
if (request.query['name'] == 'abc' &&
request.query['pass'] == '123') {
return await innerhandler(request);
} else {
return responsex.unauthorized('authentication failed !!!');
}
};
};
@override
void entrypoint() {
var r1 = app.group('/v1');
// var middleware = pipeline().addmiddleware(verification()).middleware;
r1.use(verification());
r1.get('/hello', (request request) {
return response.ok('hello-world');
});
r1.get('/greet/:name', (request request, string name) {
return response.ok('hi,$name');
});
var r2 = app.group('/v2');
r2.get('/hello', (request request) {
return response.ok('hello,arowana');
});
r2.get('/user/:name', (request request, string user) {
return response.ok('hello, $user');
});
}
@override
futureor<response> call(request request) {
print('current isolate [${isolate.current.debugname}]');
return app.call(request);
}
}
void main() {
var app = application(myachannel());
app.options = applicationoptions()..address = '127.0.0.1';
app.start(numberofinstances: 2,consolelogging: true);
}
