Documentation

Observations

• Throughout the code, ":modelModule" is used in comments as an alias to the name given when the module was instantiated, but there is no such param in the routes.
• Options are passed through as a parameters object, and all of its contents are required, otherwise there will be missing routes and variables. However, error handling of undefined hasn't been implemented yet.

Basic initialization

First instantiate a new model by calling var modelInstance = new crudEasy.newModel(url, collectionName); and then use the api and crud routes by calling app.use([route], crudEasy.crudRoute(modelInstance, optionsObject)); and app.use([/api/route],crudEasy.apiRoute(modelInstance, optionsObject));.

Options

options = {
    url:            "mongodb://<username>:<password>@127.0.0.1:27017/mymongodb", // any valid full mongodb url.
