Responsive-database-manager NPM

responsive-database-manager

A Mongoose database interface that is created per JSON specs, and responds to changes to those specifications properly.

Example Usage

Install MongoDB

Features

This module is used extensively within a particular parent project. For this reason, a fair few decisions have been made which may not match other requirements. I've attempted to outline these decisions here:

Mandatory Properties

A JSON file containing properties which are mandatory, and their default values. If a new field is added without one of these properties, it will be added with the default value.

Mandatory Fields

A JSON file containing fields which are mandatory. These fields will be automatically added to new schema should the schema not already contain the fields.

Field Types

A JSON file containing mappings between subtle types and Mongoose types. With this, you can create complex types to support better validation, but storing the data properly within Mongoose. For example:

"email": "string",

an email type can be interpreted differently by the browser, server, but Mongoose will still store as a String type.

Getters/Setters/Validators/Defaults

Javascript files containing functions used to perform operations against data. For example:

module.exports = {
  password : function(value) {
    return "●●●●●●●●";
  }
}

The above will be applied to password type fields (see Field Types - this is actually a String) in the Getters property, and thus all passwords retrieved from the database will read '●●●●●●●●' instead of their actual value.

Schemas stored as JSON

All schema are stored as JSON files, converted using mongoose-gen, to which I owe great thanks. They contain a property called 'name', and a map called 'fields', which contains all the information required, but at a minimum contains the fields within Mandatory Properties.
