mongodiagram

mongodiagram is a node module to make diagrams/schemas from given JSON inputs/files. To install it you just simply type to command line :

$ npm install mongodiagram --save-dev

It is easy to use. Let's look at the examples.

Simple Usage

First we need to create our JSON file which contains database structure.

[{
	"ForumPosts":{
		"_id":"ObjectID",
		"category":"String",
		"hits":"Integer",
		"text":"String",
		"createdDate":"ISODate",
		"author":"ObjectID",
		"replies":{
			"_id":"ObjectID",
			"text":"String",
			"createdDate":"ISODate",
			"author":"ObjectID"
		}
	}
},{
	"Users":{
		"_id":"ObjectID",
		"username":"String",
		"password":"String"
	}
}]

after saving it lets create a nodejs file to process it.

var fs = require('fs');
var mongodiagram = require('mongodiagram');

(function init(){
	var diagram = mongodiagram(fs.readFileSync('./simple_structure.json','utf-8'));
	fs.writeFileSync('output.txt',diagram,'utf-8');
})();

output.txt will be like

          Database____________________________________________________________________
         /                                                                            \
    ForumPosts__________________________________________                             Users__________
   /          \       \     \        \          \       \                           /     \         \
  _id      category  hits  text  createdDate  author  replies____________________  _id username  password
                                                     /       \        \          \
                                                    _id     text  createdDate  author

Additional Options

There are two object properties you can pass to mongodiagram as a second argument of mongodiagram object, first is:

showDataType : <boolean>

It shows data types of each element in your JSON input. Default is false. The second property is :

title : <string>

It changes the title of diagram. Default is Database.

Let's look at the example of usage.

var fs = require('fs');
var mongodiagram = require('mongodiagram');

(function init(){
	var diagram = mongodiagram(fs.readFileSync('./simple_structure.json','utf-8'),
							  {
							   showDataType:true,
							   title:"ForumDatabase"
							   });
	fs.writeFileSync('output.txt',diagram,'utf-8');
})();

output will be like :

                ForumDatabase___________________________________________________________________________________________________________________________________________________________
               /                                                                                                                                                                        \

                                                                                                            _id( ObjectID )  text( String )  createdDate( ISODate )  author( ObjectID )
