            }
        },
        serverLogger: { 
            // Adding logging at the server level. Any logging logging library 
            // should work what implements the below are the 
            // possible logging levels
            debug: console.log,
            log: console.log,
            info: console.log,
            warn: console.log,
            error: console.log

Controller Documentation

The controller uses the api method implementation of restify.

For more information on restify properties see http://restify.com/docs/server-api/.

    ControllerExample : Wrapper.wrap(async helper => {//Initialize controller method
        //Helper native properties
        helper.res // response property
        helper.req//  request property
        helper.reply // setup replay for request needed to end http request 
        helper.logger // Log at different levels: debug, log, info, warn and error
        return helper.res.reply.ok('Hello World');
    })

Controller Method Example

const tortilla = require('tortilla-api');
const Wrapper = tortilla.wrapper;

module.exports={
    ControllerExample : Wrapper.wrap(async helper => {
        helper.logger.info('Hello World');
        return helper.reply.ok('Hello World');
    })
};
