Kookaburra

Kookaburra is a Hapi plugin that lets you use generator function coroutines as handlers using Bluebird.

See Bluebird.coroutine for details.

You can use the usual Hapi reply interface or let Kookaburra handle replying for you by just returning a value or throwing an error.

Example

const server = require('hapi').Server();
server.connection({ host: 'localhost', port: 3000 });

server.register({
  register: require('kookaburra'),
  options: {},
}, () => {
  server.route([{
    method: 'GET',
    path: '/foobar',
    handler: function* aHandler(request, reply) {
      const value = yield aPromiseCall();
      value.doSomething();
      return reply(value.somethingElse);
      // or simply return value.somethingElse;
    },
  }]);

  server.start();
});

Options

• patchAll:
  • Automatically patch all detected generator handlers in route tables. If disabled, you must use the handler: { coroutine: *fn() {...} } syntax to define a handler. Default value: true.
• skipReturnReply:
  • Skip replying when a return reply(); return value is detected. If disabled, you shouldn't use that syntax, but it may allow avoiding a falsely detected reply call. Default value: true.
• skipUndefined:
  • Skip replying when a undefined return value is detected. If disabled, you should always explicitly return something or Kookaburra will send an empty reply. Note that if both skipUndefined and skipReturnReply are disabled, you cannot avoid Kookaburra automatically replying other than by returning an error. Default value: true.
• skipReturnError:
  • Skip replying when return value is instanceof Error. This happens if you return reply(Error) and we shouldn't double reply. Disable if you want to return an error and have Kookaburra reply with it, though throwing the error should be your first option. Default value: true.
