json-programable-template v1.0.3

json-programable-template

Install

$ npm i json-programable-template --save

Example

Here is a basic example 

const helloWorld = {
    "rules":{
        hello:"const@hello",
        world:"const@world",
    }
};

const model = new JSONNormal().parseJson(helloWorld,null);

output: { hello: 'hello', world: 'world' }

let us move a bit deeper

const sum = {
    "rules":{
        sum:"const@1 => sum@5,6",
        sumTwo:"const@1 => sum@10,11",
    }
};

const model = new JSONNormal().parseJson(sum);

output: { sum: 11, sumTwo: 21 }

You can use key word '~' to get previous value

const sum = {
    "rules":{
        sum:"const@1 => sum@~,~,10",
        sumTwo:"const@1 => sum@10,11",
    }
};

const model = new JSONNormal().parseJson(sum);

output: { sum: 12, sumTwo: 21 }

You also can define and use you own function here as well

const moment = require('moment');

let func = {
    time(value) {
        if (
            "now" === arguments[0]
        ){
            return moment().format(arguments[1]);
        }

        if (
            arguments.length > 2
        ){
            return moment(arguments[0], arguments[1]).format(arguments[2]);
        } else {
            return moment(arguments[0]).format(arguments[1]);
        }
    },
};

const sum = {
    "rules":{
        currentTime:"time@now",
        parseTime: "const@20181021 => time@~,YYYY-MM-DD,YYYY-MM-DD HH:mm:ss"
    }
};

const model = new JSONNormal().parseJson(sum,func);

output: 
{ 
  currentTime: '2018-10-22T15:58:21+08:00',
  parseTime: '2018-10-21 00:00:00'
}

however the arguments you passed in the function should follow the rules:
function(argOne, argTwo, argThree, custom variable);
The last argument have to leave the space to the custom variable. 

Validation:
You can add validation in the template

In this example, because 123 is num, the template would display an output
let func = {
    isNum(value){
        return !isNaN(Number(value));
    }
};

const sum = {
    "rules":{
        hello:"const@hello",
        world:"const@world",
    },
    "validator":[
        "const@123 => isNum@~",
    ]
};

output: { hello: 'hello', world: 'world' }


If the validation is failed, return null; 
const sum = {
    "rules":{
        hello:"const@hello",
        world:"const@world",
    },
    "validator":[
        "const@123 => isNum@~",
        "const@aa => isNum@~"
    ]
};
output: null
const model = new JSONNormal().parseJson(sum,func);
