Can you explain a bit more what your code is doing? Are you suppose to instantiate the handler class and call it?

- nawgszy 9y agoYeah, exactly. Say you have an API request that is persisting a chunk of data to the database, like a few dependent data items. This way, you write the API request to just be a simple function invocation of the class you instantiated: (req, res, next) => { apiHandler = new APIHandler(args); apiHandler.saveData(req.body) .then( // success () => res.status(200).json(apiHandler.getResponse()), // error () => res.status(400|500).json(apiHandler.getErrorResponse()) ) I mean, it's just a pattern, and I wouldn't necessarily say I use it all the time; it's especially valuable for workers, where you have a series of functions you want to execute where some of them are going to be asynchronous. If you're just making simple create / update / get requests, it's less valuable, and you can just return a Promise from somewhere. Hopefully that gave you an idea of my motivations
