Veracityjs NPM

Veracity JS - Synopsis

Veracity JS is a plugin for validating your javascript object and ensuring you that the object you have received is consistent with what you want.

Installation

Veracity JS doesn't require anything. Just add the script into your app like this :

Basic usage

    var Veracity = require('veracityjs')

ES6

    import Veracity from "veracityjs"

How to use it

To use it, you must follow this pattern :

    Veracity.validate(<your data>, <your validation pattern>);

Example

Basic example

    var data = {
        test: 1
    };
    
    Veracity.validate(data, [
      {name: 'test', type: Veracity.Type.Integer, required: true}
    ];      // It will return true

You don't have to pass an object, you can just pass a variable and test its type

    var test = "string test";
    
    Veracity.validate(test, Veracity.Type.String);  // It will return true
    Veracity.validate(test, Veracity.Type.Integer); // It will return false

Here is a complete example for testing all types and all parameters

    Veracity.validate({
        integer: 1,
        float: 1.5,
        string: 'test',
        array: [1, 5],
        object: { data: 1 },
        objectWaterfall: { float: 1, integer: 1.5 },
        amongValues: 3,
        amongTypes: '3',
        regex: 'price'

    }, [
        {name: 'integer', type: Veracity.Type.Integer, required: true},
        {name: 'float', type: Veracity.Type.Float, required: true},
        {name: 'string', type: Veracity.Type.String, required: true},
        {name: 'array', type: Veracity.Type.Array, required: true},
        {name: 'object', type: Veracity.Type.Object, required: true},
        {name: 'objectWaterfall', type: Veracity.Type.Object([
            {name: 'float', type: Veracity.Type.Integer, required: true},
            {name: 'integer', type: Veracity.Type.Float, required: true}
        ]), required: true},
        {name: 'amongValues', type: Veracity.Type.AmongValues([1, 2, 3]), required: true},
        {name: 'amongTypes', type: Veracity.Type.AmongTypes([Veracity.Type.Integer, Veracity.Type.Float, Veracity.Type.String]), required: true},
        {name: 'regex', type: Veracity.Type.Regex(/price/gi), required: true}

    ]); // It will return true

Validation Pattern parameters

Parameters	State	Explication
name	required	The name of property of the data to test
type	required	A type
required	optional	if this is required, the validation won't pass if the property doesn't exist

List of types

Type	Parameters	Explication
Veracity.Type.Integer	/	Test if the property is an integer (it won't pass if it is a float)
Veracity.Type.Float	/	Test if the property is a float (it won't pass if it is an integer)
Veracity.Type.Boolean	/	Test if the property is a boolean (even if a boolean is 'false')
Veracity.Type.String	/	Test if the property is a string
Veracity.Type.Array	/	Test if the property is an array (it will pass if it is an empty array)
Veracity.Type.Object	Array of types (optional)	Test if the property is an object (you can validate all object properties with the optional parameters)
Veracity.Type.Regex	Regular Expression (REQUIRED)	Test if the property match with the regular expression passed by paramaters)
Veracity.Type.AmongValues	Array of values (REQUIRED)	Test if the property match with one of values contained in array passed by parameters)
Veracity.Type.AmongTypes	Array of types (REQUIRED)	Test if the property type match with one of types contained in array passed by parameters)

Example

To run test, juste use :
