}
var result = jsonschemachecker.check(jsonscheme, jsonData)
console.log(result)

// output
// { validate: false,// means failed
//   jsonScheme: '{"code":"number"}',
//   jsonData: '{"code":"1"}',
//   error: 'type error: /code' }// means jsonData.code's type is incorrect(should be number)

embed object

var jsonschemachecker = require("jsonschemachecker")

        vip: false,
        address: {}
    }
}
var result = jsonschemachecker.check(jsonscheme, jsonData)
console.log(result)

// output
// { validate: false,// means failed
//   jsonScheme: '{"code":"number","user":{"name":"string","vip":"boolean","address":{"street":"string"}}}',
//   jsonData: '{"code":1,"user":{"name":"name","vip":false,"address":{}}}',
//   error: 'absence: /user/address/street' }//means jsonData.user.address.street is absence

embed array

var jsonschemachecker = require("jsonschemachecker")

var jsonscheme = {
    code: "number",
    users: [{

    }, {
        name: "name",
        vip: false
    }, {
        name: "name"
    }]
}
var result = jsonschemachecker.check(jsonscheme, jsonData)
console.log(result)

// { validate: false,// means failed
//   jsonScheme: '{"code":"number","users":[{"name":"string","vip":"boolean"}]}',
//   jsonData: '{"code":1,"users":[{"name":"name","vip":false},{"name":"name","vip":false},{"name":"name"}]}',
//   error: 'absence: /users/[2]/vip' }//means jsonData.users[2].vip is absence
