Mongoosify

Mongoosify is a Javascript library to parse a JSON Schema into a Mongoose Schema.

Installation

npm install mongoosify --save

Usage

Let suppose the JSON object is saved as jschema.json

{
  "type":"object",
  "properties":{
    "address":{
      "type":"object",
      "properties":{
        "street":{"type":"string"},
        "house":{"type":"string"},
        "city":{"type":"string"}
      }
    },
    "firstName":{"type":"string"},
    "lastName":{"type":"string"},
    "title":{
      "type":"string",
      "enum":["Dr","Prof.","Ph.D."]
    },
    "email":{
      "type":"array",
      "items":{"type":"string"}
    },
    "age":{"type": "integer"}
  }
}

The following code demonstrate how to parse a JSON schema from the jschema.json file into a mongoose schema (I called it mongoosify :D)

var mongoosify = require("mongoosify");
var mongoose = require("mongoose");
var myJsonSchemaFile = require("./jschema.json");
 
var mySchema= mongoosify(myJsonSchemaFile);
 
var Schema = mongoose.Schema;
var mongooseSchema = new Schema(mySchema);
 
//now you are ready to go...

How to run tests

$ npm test

Important notes

Mongoosify will always try to cast type implicitly if a schema and the data don't have a same type. If a casting is not possible (e.g. "Hallo" can not be cast into a number but "10" can be) and CastError will be throw by Mongoose.

Current task in progress

Unit tests for the actual code

Planned features

1. Enable reusability with keywords $ref, $schema and id.
2. Evaluation of the following constraints:
   • schema keywords:
     • additionalProperties
     • required
   • array keywords:
     • minItems
     • maxItem
     • uniqueItems
   • numeric types keywords:
     • minimum
     • maximum
     • multipleOf
   • string keyword:
     • format
