validator-json

All spirits come from validate

This module just fixed two issues of validate:

• array(simple or nested) validation
• validate for number 0, boolean false and string '' (you can see this issue)

Only validate for:

• type
• exist

Install

npm install validator-json

Usage

var validator = require('validator-json');
var errors = validator(obj, schema);

Example

var validator = require('validator-json');

var schema = {
	name: {
		first_name: { type: 'string', required: true },
		last_name: { type: 'string', required: true }
	},
	nickname: { type: 'string', required: false },
	age: { type: 'number', required: true },
	married: { type: 'boolean', required: true },
	hobbies: { type: 'array', required: true, elemType: 'string'},
	games_loved: { 
		type: 'array',
		required: true,
		elemSchema: {
			name: { type: 'string', required: true },
			years_played: { type: 'number', required: true }
		}
	}
}

var object4pass = {
	name: {first_name: 'Xv', last_name: 'kivi'},
	nickname: 'hammer',
	age: 23,
	married: false,
	hobbies: ['computer games', 'basketball'],
	games_loved: [
		{
			name: 'dota',
			years_played: 4
		},
		{
			name: 'lol',
			years_played: 1
		}
	]
}

var object4npass = {
	name: 'hello',
	nickname: 999,
	age: '23',
	married: 'false',
	hobbies: ['computer games', 999],
	games_loved: [
		{
			name: 'dota'
		},
		{
			years_played: 1
		}
	]
}

console.log('object for pass: \n', validator(object4pass, schema), '\n');
console.log('object for not pass: \n', validator(object4npass, schema), '\n');

Note

Schema only accept 4 property:

• type
• required
• elemType
• elemSchema

elemType and elemSchema should not exist at the same time

if the object you want to validate like this:
['some string', 'hello world']
then you should set schema like this:

{  
    type: 'array',  
    required: true,  
    elemType: 'string'  
}  

if you want to validate object like this:

[
    {  
        name: 'kivi',  
        age: 100
    },  
    {  
        name: 'ivik',  
        age: 20  
    }  
]

then you should set schema like this:

{  
    type: 'array',  
    required: true,  
    elemSchema: {  
        name: {  
            type: 'string',  
            required: true  
        },  
        age: {  
            type: 'number',  
            required: true  
        }  
    }  
}
